For many individuals, the option iGenics Review of the two is not even a consideration. The limitations are due to the fact that these candidates have thin corneas and are only suited for PRK surgery. If LASIK surgery were to be preformed on an individual with a thin cornea than their is the possibility of jeopardizing the integrity of the cornea and therefore PRK is the recommended method because it does not do as much change to the structure of the cornea when compared to LASIK. This decision is one that should be made carefully by an individual only after learning and understanding both options that are available for laser eye surgery. You should do your research and weigh the pros and cons of both procedures and make a decision that works best for you. What type of light is dangerous for your eyes? Ultraviolet light is dangerous and its negative effects are well known. It is invisible and cannot be seen. Most sunglasses protect against UV light as this is the commonly feared. While UV light is beneficial to the skin in small doses, where it promotes the production of Vitamin D, in larger doses it can cause cancer among. It also damages the structural integrity of the skin, noticeably damaging the collagen and leads to an increase in what is described as age related damage. Ultraviolet radiation has been established to cause damage to the lenses and can lead to cataracts and other damaging effects. Both short term exposure to UV light as well as long term exposure can lead to severe damage to the cornea, retina and other parts of the eye. There is a second type of light which is just as dangerous, however, unlike ultraviolet light, it can be seen. It is blue light that can lead to a specific and very dangerous problem known as Macular degeneration. This occurs when damage to the macula region of the retina causes a drastic loss of central vision. Blue light, and also Violet light, are the highest frequency of the visible spectrum. High levels of exposure to Blue light cause irreparable damage to the human eye. Unlike other colors on the visible spectrum, the eye cannot handle a significant amounts of blue light and can be overloaded. When the eye becomes overloaded with blue light there is an increased risk for oxidative stress as well as damaging structural effects on the cornea and retina. Researchers have found that retinal cells exposed to blue light have a higher loss of mitochondrial activity then cells which have been kept in the dark for the same amount of time.
