Your Cornea: Conditions, Symptoms and Treatments

The cornea is located at the front of the eye where protection is vital to the health of the eye. This provides protection for the eye as much as possible but can be contaminated by bacteria or fungi. There are some symptoms known for when the eye is contaminated and for when other situations occur as well, for each symptom, there are treatments to help. Corneal transplants are the last resort for treating these symptoms but can be the best option for some cases.
The cornea is the transparent protective outer layer of the eye. It helps to protect against dirt, germs, and any other particle that can harm the eye. It also helps filter out some of the sun’s ultraviolet light. The cornea plays a critical role in vision as it refracts or bends light when it enters the eye. The three most important layers of the cornea are the epithelium, stroma, and the endothelium. The epithelium is the most superficial part of the cornea; it helps prevent external matter from entering the eye. The stroma is found behind the epithelium, it is made up of water and proteins giving it an elastic yet solid form, and it is the thickest part of the cornea. Lastly, the endothelium is a single layer of cells between the stroma and aqueous humor which works similar to a pump as it expels excess water that’s absorbed by the stroma.  
Maintaining the cornea is vital to keeping the eye healthy and preventing any diseases from occurring. Depending on the environment, always protect the eyes as well as possible. Dietary supplements are also an excellent way to get the nutrition and vitamins that the body needs, however, be sure to check with a dietitian before taking supplements without it being recommended. However, the main way to keep the cornea healthy is through nutrition with foods such as fish, broccoli, walnuts, sweet potatoes, eggs, salmon, and carrots. Eating healthy with these such foods also help with the conditions of Fuchs’s dystrophy, corneal dystrophy, and keratoconus. Keratoconus is a well-known condition that very much affects the cornea, but other conditions such as ectasia and astigmatism are conditions that affect the cornea is significant ways as well. Keratoconus is when the cornea gradually thins and bulges into a cone shape. Astigmatism is when the lens or cornea has a different curvature in one direction. Lastly, ectasia is when the cornea bulges from being weakened from lasik surgery. To help prevent from experiencing any corneal issues refrain from smoking, sunlight exposure, and exercise regularly.
Treatment of corneal damage can be hectic to deal with which is why keeping the cornea healthy is vital to the eye. For ectasia and keratoconus, a non-surgical procedure named Holcomb CR-3 is used to strengthen the corneal structure. As for astigmatism contact lenses or glasses can be the solution for less severe cases; whereas, for more serious cases corrective surgery is the best solution. Corneal transplant is for the most severe of cases of a damaged or diseased cornea. A corneal transplant removes the damaged or diseased cornea and replaces it with a donor.
   Since the cornea protects the eye in many ways taking care of it should be something that should be a priority that pays off in the end. Although the cornea does protect the eye in its ways, take the precautions mentioned above and be consistent with a routine.

Are your eyes dry & itchy?

Dry eye, or dry eye syndrome, can happen to anyone and can be very disturbing. Some of the causes for dry eye are easy to treat, and others can be more challenging but also dealt with simply. The symptoms are relatively easy to spot, and again the syndrome can be treated depending on how the eyes are acting.
The cause of dry eyes consists of about eight different reasons. The causes of dry eye syndrome can be due to lots of reading or digital usage, being in a dry environment, overuse of contacts, and lasik surgery. Some other causes could be from particular types of drugs, not consuming enough food with essential fatty acid or anti-inflammatory foods, certain types of health conditions, and lastly a deficiency of tear-producing glands. If you can find out where the problem is coming from sooner than later, you will be able to get rid of the disturbance much quicker.
The signs of dry eye can either be very distinct or hard to read. The signs could be any of these possibilities; there is blurriness, sensitivity to light, irritation from windy conditions, fatigue of eyes near the end of the day, problems with wearing contacts, scratchy or gritty feeling eyes, excessive tearing, and red eyes. Itchy eyes is also a result of dry eye syndrome but, be sure not to rub your eyes as much as possible when dealing with any of these disturbances as it can cause damage to the eye.
Treating the eyes can be simple once the cause and symptoms are known. The best ways to treat dry eye syndrome is by checking medication thoroughly, eating healthy foods rich in omegas, avoid pollution and irritants, balancing hormones, take care of contacts efficiently, use eye drops, drink lots of water, and simply blink often. Again, if you think you’re experiencing dry or itchy eyes do not hesitate to try some different treatments.
Maintaining your eyes throughout the day can be difficult when wanting to do other things on the agenda. But, try to take care of your eyes by taking precautions before having to deal with the symptoms.

Avoid headaches with new lenses

Avoid headaches with new lenses
Headaches are the prime result from eyestrain, but how do I avoid headaches with new lenses in the first place? New contact lenses or eyewear can be stressful to the eyes when being prescribed a new prescription for the eyes to adjust to. There are many causes of eyestrain that can be prevented if taken care of properly. Causes of eyestrain with both contacts and glasses can be difficult to control, but relatively easy to relieve.
The main causes of eye strain with contacts could be getting the wrong prescription, receiving poorly fitted lenses, dry eye syndrome, or computer vision syndrome. Getting the wrong prescription does not happen very often, but being given a prescription that is too strong or too weak can cause a lot of strain on the eyes. Poorly fitted lenses are when contacts dry out and tighten up when being worn for several hours. Dry eye syndrome can cause the eyes to become more sensitive to light which results in squinting and in turn causes a muscle tension headache. Lastly, there is computer vision syndrome where headaches can be caused by working at a computer for long hours. Although contacts don’t necessarily increase the chance of getting computer vision syndrome, the contacts can dry out faster and cause more discomfort.
Glasses have almost the same causes for eye strain. The causes of eye strain with glasses could be getting a new prescription or using a computer for several hours. Getting a new prescription with glasses can be difficult on the eyes. It’s difficult because during the times that the glasses are worn the eyes can strain to adjust to the new prescription. As for using the computer while wearing glasses, eye strain is mainly caused by the glare from the screen.
Preventing or relieving eye strain can be simple with these different types of techniques. To avoid headaches with new lenses when getting a new prescription, try to wear the new prescription as often as possible for the eyes to adjust properly. If you are noticing that the prescription you received is off in any way, consult your eye doctor right away. When using a computer, limit how long you work at the computer for and take a break every twenty minutes for the eyes to rest. To relieve eye strain, again take breaks and try relaxing your eyes open in a dark room. Having your eyes open in a dark room allows them to rest without having to focus on anything. To aid when trying to get rid of a headache try taking a pain reliever and continuing one of these techniques.
If you don’t feel sure or comfortable with dealing with a headache personally, consult the eye doctor immediately. If you do decide to attempt in relieving the pain personally, try to be diligent and patient with the process.
 

Know your contacts & how to manage them

The contact lens today has been manufactured to structurally fit a human eye and maintain consistent results for the person it is being worn by. But what are contact lenses? The three most important things of having contacts are knowing what they’re made of, what kind of contact is being worn, and how to manage or take care of the contacts themselves.
 
The material that a contact lens can be made of depending on whether the contact lens is a soft lens or a hard lens. The material of a soft lens is made of Hydrogel which is a water-absorbing polymer that uses the moisture content to transmit oxygen to the eye through the lens. Another material for soft lenses is Silicone Hydrogel which has been developed for even greater oxygen permeability, which has become more of use since it is considered more comfortable. As for hard contact lenses, they are manufactured with hard polymers (plastics) that are naturally porous enough to allow oxygen to reach the eye. The hard plastics give the lens wearer a higher level of optical clarity at the risk of initial discomfort while getting used to the lens. So that you can have a high level of oxygen breathability, scientists had to add fluorine to the lens material to achieve the required oxygen permeability that would allow hard lenses to be worn long-term. Through adding fluorine, rigid lens materials develop microscopic holes and pores which allow oxygen to flow freely through the lens despite the fact that the lens is a solid material.
 
After knowing what a contact is made of, you need to know what kind to wear. The four different types of contacts to consider, when finding the best contact for you, are dailies, weeklies, monthlies, and extended wear. Each contact is unique, but some are more efficient than others based on who is wearing them. Here is a brief description of each contact lens mentioned so far.
 
Dailies: Daily disposal contact lenses are discarded every night and replaced every morning. Daily disposable contact lenses are ideal for people with sensitive eyes because they are replaced every day. They do not accumulate the same bacterial and dirt build-up to which other contacts are prone, and they require much less care because they do need to be washed or stored overnight.
 
Weeklies: Like daily disposable contact lenses, weekly disposable contact lenses are made to last a short period; however, they do need to be disinfected and stored every night. They are made to be worn for a week and then replaced with a fresh pair. They, like daily disposable contacts, offer a comfortable and fresh feeling because they are frequently replaced.
 
Monthly Disposable: Monthly disposable contact lenses are very common. They are perhaps even the most common style of contact lenses. They should be changed every night, disinfected with a solution, and stored in a proper receptacle. Monthly disposable contact lenses are safe to wear and provide clear vision for one month.
 
Extended Wear: Extended wear contact lenses are typically those that can be worn continuously for up to seven days and six nights. Some extended wear contact lenses, Know your contact lenses and how to manage them namely those made with a silicone hydrogel, can be worn for up to thirty days straight.
 
Extended wear contact lenses have a high oxygen permeability, which means they allow oxygen to pass through them into the cornea. Extended wear contact lenses are best for people who live a highly active or unpredictable lifestyle that may not enable them to remove their contact lenses every night. They are also ideal for people with binocular vision abnormalities and those with especially bad vision who want to be able to see clearly at all times, even when waking up at night or first thing in the morning. Extended wear contacts lenses are typically worn for six days and nights and then stored in a contact lens case for cleaning while the eyes are allowed to rest. It is important to check with and adhere to the wear schedule for each brand and type of extended wear contact lenses as it can differ from brand to brand.
 
Once you are ready to start wearing the contacts, managing them is going to be the most important aspect of wearing contact lenses. Before you handle contacts, wash and rinse your hands with a mild soap. Make sure it doesn’t have perfumes, oils, or lotions. They can leave a film on your hands. If they get on your lenses, your eyes could get irritated, or your vision might be blurry. Be sure that you are wearing the contacts to their prescribed extent and no longer, as mentioned before through the types of contacts. Some contacts need special care and products.
 
Always use the disinfecting solution, eye drops, and enzymatic cleaners your doctor recommends. Some eye products or eye drops aren’t safe for contact wearers.
 
Wearing contact lenses may not be for everyone, but if you or a loved one are seriously considering wearing contact lenses, be sure to know these components of a contact lens. Knowing what the contact is made of, what type of contact is being worn, and how to manage the contact will help with safety issues that can occur when handling and wearing contact lenses.

How the sun rays can damage your eyes

Sun Damaging Your Eyes?

 
Eye medical doctors (ophthalmologists) caution us that too much exposure to UV light raises the risks of eye diseases, including cataract, growths on the eye, and cancer. Strong exposure to snow reflection can also quickly cause painful damage called snow blindness.
Growths on the eye, such as pterygium, can show up in our teens or twenties, especially in surfers, skiers, fishermen, farmers, or anyone who spends long hours under the midday sun or in the UV-intense conditions found near rivers, oceans, and mountains.
Diseases like cataract and eye cancers can take many years to develop, but each time we’re out in the sun without protection we could be adding damage that adds to our risks for these serious disorders. Babies and kids need to wear hats and sunglasses for this very reason. People of all ages should take precautions whenever they are outdoors.

Follow these tips to prevent the sun damaging your eyes:

  • Sun Damaging your eyes can occur anytime during the year, not just in the summertime, so be sure to wear UV-blocking sunglasses and broad-brimmed hats whenever you’re outside.
  • Don’t be fooled by clouds: the sun’s rays can pass through haze and thin clouds.
  • Never look directly at the sun. Looking directly at the sun at any time, including during an eclipse, can lead to solar retinopathy, which is damage to the eye’s retina from solar radiation.
  • Don’t forget the kids and older family members: everyone is at risk, including children and senior citizens. Protect their eyes with hats and sunglasses.
  • Schedule a visit at Twenty Twenty Eye Care to grab you a set of brand new stylish sunglasses.

Overuse of electronics can damage your eyes

We were always taught that staring at the Sun for too long can damage your eye’s, but I bet you didn’t know that staring at your phone or computer screen can also damage them. Prolonged use of electronics can damage your eyes according to experts when a person is viewing a computer screen their natural blink rates goes down and can cause eyes to burn, itch or get dry.
Prolonged viewing of a computer screen can make any slight existing vision defects more noticeable. It can also give you what is sometimes known as “computer vision syndrome” – eye strain, headaches, gritty eyes and blurry vision. But this is only temporary and can be minimized by:

  • Consulting with your eye care professional
  • Use the 20-20-20 rule: every 20 minutes, take a 20-second break and look at something 20 feet away
  • Consider using computer eyewear to help combat eye strain; products are available in prescription and non-prescription varieties
  • Create an ergonomically-friendly workstation with proper lighting, seat adjustments, and monitor settings
  • Maintain an appropriate distance from handheld and stationary device screens
  • Enlarge your computer text and browser windows for easier viewing
  • Limit the amount of competing for indoor and outdoor light
  • Clean electronic device screens frequently to eliminate dust and glare
  • Remember to blink; staring at screens can dry eyes

Keratoconus Diagnosis And Treatment

Are you experiencing prolonged blurred vision and difficulty seeing at night? Could you be suffering from Keratoconus? Learn about Keratoconus symptoms, diagnosis & treatment.
Keratoconus Symptoms
First of all, what is Keratoconus? Your body has many parts that need to remain flexible to be fully functional. This includes your eye’s cornea. Keratoconus is when your cornea can no longer flex, due to becoming very thin. It might bulge, like a cone because it is stuck in one shape. Keratoconus might differ from person to person. Generally, symptoms might consist of the following: blurred vision, light sensitivity, difficulty with night vision, light halos, eye strains, headaches and eye irritation. Of course, many of these symptoms might have other causes. That is why its early stages require diagnosis from a competent eye doctor. The most severe Keratoconus can make it very difficult for you to see and live a normal life.
Diagnostic Eye Exam
Your cornea has a normal cone shape, with Keratoconus this become more pronounced, bulging and deformed. Our professional eye doctor can use a slit-lamp eye exam to determine if you suffer from corneal thinning, Fleischer’s ring, Vogt’s striae or Apical scarring. What do these medical terms mean? Fleischer’s ring is an iron colored ring around your eye’s cone. Vogt’s striae are stress lines caused by corneal thinning. Apical scarring occurs at the apex of your eye’s cone. Your vision doctor can also use eye refraction, keratometry or computerized corneal mapping for Keratoconus diagnosis.
Keratoconus Treatment
Treatment all depends on the severity of your Keratoconus. Mild to moderate Keratoconus can be treated with stronger eyeglasses or contact lenses. The cornea should regain stability after a couple of years. Other possibilities are Corneal Vaulting Devices. Due to the larger bulge, these vision devices must clear your eye to prevent any rubbing. The worst case scenario could require surgery. Preventative eye care might involve tests to see if any chronic or long-term problems are serious. We, at Twenty Twenty Eyecare can give you a Keratoconus eye exam. Keratoconus diagnosis & treatment can help you improve your vision. We are your friendly neighborhood Tulsa, Oklahoma optometrist.

Corrective Sports Lenses

Do you play sports? Some athletes also have eye problems, but it doesn’t stop them from doing what they love. Using corrective sports lenses is perhaps the most convenient alternative for correcting your vision while doing the sports you love. Unlike to using glasses, contact lens does not fog up or slip off. Instead, it gives you the freedom to focus on the game.
 

Different Types of Sports Corrective Lenses

GP Contact Lenses
GP contact lenses are also known as rigid gas permeable, or RGPs, made of firm, impervious plastic that conveys oxygen and offers more comfort and excellent health. GP contact lens counters protein deposits from tears and perspiration. Also, it doesn’t absorb water, so your eyes will stay extra comfortable throughout a set of badminton, tennis, and squash.
 
Hybrid Contact Lenses
Hybrid contact lenses are composed of a GP lens center surrounded by a “skirt” of soft lens substance. The purpose is to give the crisp optics of a GP with the convenience of soft lenses. It is also larger, similar to soft lenses so that they don’t bulge on your eye while playing a game.
 
Daily Disposable Soft Contact Lenses
Aside from perfect for casual use, daily contact lenses are also suitable for sports activities. It is moderately inexpensive to substitute and can be tossed away after application; this indicates no cleaning solution is needed, making them trouble free. Disposables might be best for you if you find yourself too busy to clean traditional contact lenses
 

How To Decide Which Option to Choose

Getting the right sports lenses for your needs is significant, so the safest thing you can do is to consult your eye doctor before buying anything. Our doctors at Twenty Twenty Eyecare will have your best care in mind while choosing the correction prescription, you can be positive that you will enjoy your favorite sport with convenience.

Consequences Of Not Cleaning Your Contact Lenses

Cleaning Your Contact Lenses:
You started as a new contact lens wearer with the best intentions for your eye health. Looking forward to the luxury plus convenience of contacts, but sooner or later, those intentions might dwindle. The three points to keep in mind for all contact lens wearers include improperly cleaning your contact lenses, overextending your contact lenses wearing schedule or overextending your contact lenses replacement schedule can damaging your eyes and put your eyes at risk. Contact lenses are classified as medical devices and are controlled by the US Food and Drug Administration (FDA). For safety purposes, they cannot be purchased without an expert fitting and a current contact lens prescription signed by a licensed eye care physician.
The moment you start extending your wearing schedule longer than that prescribed by your eye care professional or stop cleaning your contact lens, you put yourself at a higher risk for eye infections. There are many types of bacteria that can damage your eyes, one of them called microbial keratitis occurs when bacteria, viruses, or amoebae invade the cornea. In extreme cases, keratitis can lead to blindness.
The Food and Drug Administration recommends contact lens users use extra care in preserving, cleaning, storing, and disinfecting contact lenses as well as their storage cases and solutions. Not adhering to healthy hygienic practices might result in frightening consequences such as:

  1. Going blind: Center for Disease Control and Prevention predicts that blindness caused by a severe eye infection can hit one out of every 500 contact lens user each year. To lower the risk of serious complication related to contact lens use, users should avoid sleeping with their contacts on, wearing them for too long, sharing with friends, contamination by washing or contact with water or mixing different or expired storage solutions not recommended by your primary eye care professional that might lead to corneal irritation or scarring
  2. Contact lens parasites: Using your contact lens after its expiration date or over wearing them either by extended hours or replacement schedule can permanently harm your corneas. A shortage of oxygen can impair the surface of the epithelial tissue, forming tiny wounds into which the bacteria can quickly infect, extending to the rest of the eyes and providing an ideal breeding ground for parasites. Swimming in contact lenses can also be another cause of contact lens parasites. Even if you properly disinfect contact lens, you can still acquire Acanthamoeba keratitis if you wear contact lens while swimming. You never know what kind of bacteria could be lurking in swimming pools, hot tubs, drinking water, lakes, or sea water.
  3. corneal ulcers or Eye Ulcers: The Cornea is a clear layer of tissue at the front of the eye often described as the window of the eye and allows light to enter. Wearing contact lens for too long, or wearing them while sleeping can lead to an infection that causes an open sore on the cornea with inflammation and death of corneal tissue. This sore if left untreated can lead to permanent scarring and in severe cases the need for a corneal transplant.

Always see your eye doctor as directed for routine contact lens eye check-ups and your annual eye exam. Eye doctors can identify a small problem before they become big ones, and assist in keeping your eyes healthy and protected while you wear contact lenses.
