Does High Altitude Affect LASIK Safety?

Is having Colorado lasik laser eye surgery less safe than, for example, having LASIK in California? Many eye related complications can arise due to high altitudes. For example, people that live in high altitude areas have a difficult time wearing extended wear contact lenses. Although there are now contact lenses that you can leave on overnight, high altitude can cause problems that don"t occur at regular elevation. This and many other such issues related to the elevation are largely caused by the swelling of the cornea. This swelling is known as corneal edema. As there are more cases of corneal edema in high altitude areas, many people question whether undergoing LASIK surgery is safe in those places. Of course, this is a valid concern as our eyes are our life and you should address this query and discuss it with your LASIK surgeon. But, most experts do agree on the fact that there are no more risks at high elevation than you have at regular altitude. This essentially means that you can have a safe and sound LASIK surgery in Colorado and other high altitude places.

Nearsighted individuals can see things when they are brought closer to their eyes. For the cosmetic reasons, oh well everybody wants to look ravishing and stand in a crowd.

Vitamin Supplements For Cataract Prevention, Proceed With Caution

In an effort to stay healthy, and prevent disease many of us have been taking vitamins. When examining the physiology of our eyes, it makes sense in certain instances to supplement our diets, and improve the metabolism of tissues. There are several problems that arise with that point of view. The first; is that many of these supplements have not been proven to be useful. The second; is that there can be drug interaction between the vitamins and other medications. Therefore care must be taken, and always inform your doctor of anything that you take. Many studies have suggested that taking Vitamin E will prevent cataract formation. As such, many seniors have rushed out and started taking this fat soluble supplement. However, a recent 10 years study published in the May issue of Ophthalmology concluded that there is NO benefit in taking the vitamin E with regard to preventing cataracts. The study followed over 37, 000 women and found no difference between those taking the vitamin and those that did not.

Buying Glasses - What You Need to Know

One of the first things that you need to know before you even start looking for a new pair of eyeglasses is that you'll need to have your eyes checked first. Even though you might have a pair of prescription eyeglasses that is only one or two years old, you need to be careful before you go to fill them again because prescriptions often change quickly-especially as you get older. It's not uncommon for a person in their forties to need to get a pair once every two or three years. So once you know that it's time to get your eyes tested, you need to make another decision specifically about how you're going to do just that. While many people think that just getting a pair of inexpensive reading glasses from the drugstore will be good enough, there are some reasons why you need to visit your eye doctor on a regular basis. For one, while these drugstore glasses work for some people, it's impossible to catch some of the more dangerous eye diseases unless you get a regular checkup. As well, if you've got a different prescription in each eye, the drug store variety of reading glasses won't work.

In Search of Cheaper Glasses

It wasn't until my domestic and financial situation changed dramatically several months ago that I realized that I needed to start some serious budgeting if I was to survive. Despite the fact that I consider myself very computer literate and pretty up to date on buying over the internet, it never occurred to me that I could actually buy prescription glasses in that way. Sure I've purchased books, CDs, software, cameras etc from Hong Kong, China, Australia and the UK. But spectacles? In the past I would have my eyes checked by my optician, who would draw up the prescription necessary to be followed for my glasses to be made correctly to give me good vision. And guess what? The optician sold me the glasses as well - how convenient! With more and more glasses frames retailers cropping up in malls, it became obvious that I could actually shop around to have my prescription filled. More choice in brands was a revelation - and the designer frames were fantastic, but expensive. Then I found myself with a newly broken pair of glasses, and a reduced income.

Eye Exercises

Some people have a problem getting their head around the idea of eye exercises, and not so long ago it was considered to be a new age fad with no scientific backing. New research, however, has proved that bad vision isn't always caused by genetics; lifestyle and environment can play a major part in the health of our eyes. Man is naturally a hunter, and the eyes of a hunter are designed to seek out and identify at some considerable distance. It is a known fact that people like farmers and sailors who spend a lot of time looking into the distance often retain good eye sight well into old age. In a natural environment we exercise our eyes all the time. When we look at the horizon, for instance and then look at something close by, our eyes or automatically refocus. When we are doing this all the time, our eye muscles retain their elasticity and strength. The tiny muscles that control our eyes are just like any other muscle in our body, they need to be exercised regularly. Constant use and exercise means the muscles will remain supple and strong.

Selecting the Right Sunglasses

To protect yourself from cataracts and other vision problems associated with ultraviolet (UV) light radiation, what should you do? Wearing sunglasses immediately comes to mind but do they really protect your eyes from the sun? To compare how well sunglasses block UV rays, Consumer Reports tested more than 48 brands using a spectrophotometer. This instrument measures the amount of UV and visible light which sunglasses block. The standards used were those issued by the American National Standards Institute (ANSI). "The ANSI standards apply to three classes of nonprescription sunglasses: cosmetic, general purpose, and special purpose sunglasses. The standards include limits on transmission of both UVB and UVA (the two kinds of UV rays that damage the eyes). Cosmetic models are allowed to transmit up to 30 percent of the UVB striking the sunglass lens. General purpose models, however, must block at least 95 percent of the UVB and much of the UVA as well. Standards for special purpose models - sunglasses used for mountain-climbing, skiing, and the like - are the most stringent.
