Sunglasses
Even before LASIK surgery, protective sunglasses should always be worn in the sun to protect the eyes from ultra-violet rays. After LASIK it is even more imperative that the eyes are not subjected to any risk of damage from the sun's rays. Ultra violet rays can actually reverse the effects of LASIK and can cause a corneal haze to develop. They can cause cataracts to develop and cause retinal damage.
Polarized sunglasses are a great option. These sunglasses dramatically reduce the glare caused by light reflecting off flat surfaces such as roads, water and glass buildings. Reduced glare helps preserve your vision and also maintain its health.
LASIK usually eliminates the need for prescription sunglasses since LASIK corrects your vision problems. However, photochromic lenses are a good alternative. Photochromic lenses automatically darken in sunlight and then return to a relatively clear state indoors. Photochromic lenses are very convenient, but they do have a drawback: UV rays are required to activate the tint.
Dry eyes after LASIK are so common that they occur in about half of all LASIK patients. While the condition usually is temporary and mild, significant numbers of people continue to have dry eyes for months or even years after a procedure.
But to keep the problem in perspective, many people who seek LASIK already have dry eyes. As an example, contact lens wearers who find their lenses uncomfortable because of dry eyes may investigate LASIK as an alternative because they do not want to wear eyeglasses.
