I just bought a pair of $250.00 reading and computer bifocals with coated lenses. The clerk said that if I cleaned them with the proper cloth and solution, they'd last 1 year. ONE YEAR! Suggestions for making the coating on the lenses last longer? Thanks!
My eyeglasses used to get scratched all the time and I couldn't figure out why. When I cleaned them I would use glass cleaner and a towel. I was told by my eye dr. that glass cleaner is too harsh and it removes the coating that is on the lenses and to use t-shirt material to clean with. In the meantime I bought a glasses cleaning kit from Walmart. Perfect! The solution is diluted but still cleans the lenses and it comes with a special cleaning cloth. I haven't had any scratches on my lenses for 2 years.
One thing I learned from working for an eye dr. was to be sure to rinse the lenses first, wash with mild soap and water, then dry gently with a lint free cloth. The rinsing is the most important part as it removes any particles that would scratch the finish during the soaping or drying.
I agree with getting the right cloth, microfibre is good. But also, RAINex, used on car windshields, keeps the fog factor down, and a little goes a long way in protecting the lenses. by the way, is this my neice Holly, that has three beautiful little girls? :)
Ditto to what ChloeA said! Tissues and paper towels are biproducts of trees and abrasive. I even have a pair of coated glasses that are four years old and not a single scratch from using cotton cloth. Most of the time I only use water and no soap.
With proper care they should last a lot longer than a year. However, I can tell you from experience that the coating is very easily scratched. It's so delicate that you should never use something like a kleenex or paper towel on it. Cotton fabric is okay--in fact, I wash my lenses with my hands using soap and hot water, then dry them with a clean towel and have no scratches--this time .
