Protecting Your Eyes from Solar Radiation

The sun supports all life on our planet, but its life-giving rays also pose dangers.

The sun’s primary danger is in the form of Ultraviolet (UV) radiation. UV radiation is a component of solar radiation, but it can also be given off by artificial sources like welding machines, tanning beds and lasers.
Most are aware of the harm UV radiation can do to the skin, but many may not realize that exposure to UV radiation can harm the eyes or that other components of solar radiation can also affect vision.
There are three types of UV radiation: UV-C is absorbed by the ozone layer and does not present any threat; UV-A and UV-B radiation can have adverse long- and short-term effects on the eyes and vision.
If your eyes are exposed to excessive amounts of UV radiation over a short period of time, you are likely to experience an effect called photokeratitis.

Like a “sunburn of the eye”, photokeratitis may be painful and include symptoms such as red eyes, a foreign body sensation or gritty feeling in the eyes, extreme sensitivity to light and excessive tearing. Fortunately, this is usually temporary and rarely causes permanent damage to the eyes.
Long-term exposure to UV radiation, however, can be more serious. Scientific studies and research have shown that exposure to small amounts of UV radiation over a period of many years increases the chance of developing a cataract and may cause damage to the retina, a nerve-rich lining of the eye that is used for seeing. Additionally, chronic exposure to shorter wavelength visible light (i.e. blue and violet light) may also be harmful to the retina.
The longer the eyes are exposed to solar radiation, the greater the risk of developing later in life such conditions as cataracts or macular degeneration. Since it is not clear how much exposure to solar radiation will cause damage, the AOA recommends wearing quality sunglasses that offer UV protection and wearing a hat or cap with a wide brim whenever you spend time outdoors. Also, certain contact lenses can provide additional UV protection.
To provide adequate protection for your eyes, sunglasses should:

• block out 99 to 100 percent of both UV-A and UV-B radiation;
• screen out 75 to 90 percent of visible light;
• be perfectly matched in color and free of distortion and imperfection; and
• have lenses that are gray for proper color recognition.

The lenses in sunglasses should be made from polycarbonate or Trivex® material if you participate in potentially eye-hazardous work or sports. These lenses provide the most impact resistance.
If you spend a lot of time outdoors in bright sunlight, wrap around frames can provide additional protection from the harmful solar radiation.
Don’t forget protection for children and teenagers. They typically spend more time in the sun than adults.
Be sure to see your doctor of optometry at least every two years [recommended schedule of examinations] for a comprehensive eye examination. It is a good way to monitor your eye health, maintain good vision and keep track of your solar radiation protection needs as well as new advances in eye protection.

Micheal's Refractive Lense Exchange surgery

1. What convinced you to go through with the surgery? And what made you choose this Clinic?

 I had worked in Korea and knew people who had used Korean surgery before so felt confident with this. I looked on-line and read the different recommendations and also noted that a group, I belong to, mentioned your clinic  in their newsletter.
2. Tell us about what has changed since you had your surgery. What are the major changes, comparing your life before and now after, the surgery?

The major changes include being able to work better at my teaching job because I have clearer eyesight. I love being able to watch a show and see it all so clearly, (but, I don't like the fact that i can see all the lines on my face which were not so obvious to me before. I am really  so pleased to have done this surgery.

3. Were there any inconveniences during the recovery process? Tell us about how satisfied you are with your newly improved vision.

Any inconveniences were so minor, like wearing an eye patch for 4 hours, or remembering to use the eye drops, that they are not really worth mentioning. It was all worth it. I am more than satisfied with my new eyes.   

4. What were the most valuable and memorable experiences at Joeunnun Eye Clinic?

The staff were all so very helpful and understanding. English was not a problem as Moon Joo and others had enough English to understand my needs (thank you). The surgeon was considerate and careful and explained the procedure, so i was not afraid.    

5. Finally, what else do you want to tell us (our medical staff, doctors, and nurses)? Anything is OK, including some of your ideas that may help  us to improve ourselves.

  You all did a very good job. The only suggestion I have is better instructions for finding your clinic. Your map is not clear to us foreigners and even when we asked some Chinese people to help they could not. I would suggest you draw a new map and add the MacDonald's location to it.  Also include that it is within 15 steps of exit 12 or something along these lines.

Thank you to the staff, including nurses, doctors and reception. You all helped make this a comfortable experience and I have recommended your clinic to friends.

Z4 SCOUT LASIK

The staffs were friendly and helpful, Doctor seemed to competent and gentle.

 I was mildly off put by the giggles from surgical support staff who fumbled and dropped equipment and were seemingly inept at adminstering analygisic eye drops before the surgery. The surgery was comfortable even though I was a bit worried about my eyes However considering that lasers were cutting holes through my eyeballs It was surprisingly minor procedure.All in all regarding the surgery, It was quick, relatively painless and the doctor seemed competent.I would have consider this a fantastic procesure,  However unfortunately as the anesthesis were off the pain became so excruciating that my eye muscles bagan to spasm continuely. I was concerned that this contractions may have affected the healing prrocess and the outcome of the surgery.

what irks me is that the simple prescription of the anelgesic eyedrops, or a single dose of a muscle relaxent, or an opite would have mitigated the contractions releaved the pain and allow the patient to sleep through the healing process.
 Now after 1 month, My eyes are getting better and I am very happy with the result that I could see better without glasses,  Thank you for the help and wish to be your business goes well.

  * Like what I said. I think because every person has different level of pain nervs, It would help the patients more if they would have proper medicines for after surgery.

5 Foods for Healthy Eyes

You've probably heard that carrots and other orange-colored fruits and vegetables promote eye health and protect vision, and it's true: Beta-carotene, a type of vitamin A that gives these foods their orange hue, helps the retina and other parts of the eye to function smoothly.

But eating your way to good eyesight isn't only about beta-carotene. Though their connection to vision isn't as well-known, several other vitamins and minerals are essential for healthy eyes. Make these five foods a staple of your diet to keep your peepers in tip-top shape.

Leafy greens

They're packed with lutein and zeaxanthin—antioxidants that, studies show, lower the risk of developing macular degeneration and cataracts.

Eggs

The yolk is a prime source of lutein and zeaxanthin—plus zinc, which also helps reduce your macular degeneration risk.

Citrus and berries

These fruits are powerhouses of vitamin C, which has been shown to reduce the risk of developing macular degeneration and cataracts.

Almonds

They're filled with vitamin E, which slows macular degeneration, research shows. One handful (an ounce) provides about half of your daily dose of E.

Fatty fish

Tuna, salmon, mackerel, anchovies and trout are rich in DHA, a fatty acid found in your retina
