While most people see very clearly without glasses after laser vision correction you still might need or desire corrective lenses for certain activities (driving at night for example) if you have mild residual refractive error after surgery. If you're over age 40 and have signs of presbyopia eyeglasses with progressive lenses will give you clear vision at all distances and also shield your eyes from dust debris and drying wind or air conditioning. Photochromic lenses are beneficial because they protect your eyes from 100 percent of the suns UV rays and darken automatically in sunlight. (This is particularly helpful if you are sensitive to light after surgery.) Whatever type of glasses you choose to wear after LASIK (including reading glasses) you will experience the best clarity and comfort if the lenses include anti-reflective coating. Ask your optician for details.
