Hello,

I'm nearsighted and have been wearing glasses for 25 years or
so. I've noticed that whenever I get new glasses the new lenses
seem to work much better, clearer and sharper, even though
they have the same perscription. Do lens "wear out" over time?
Does it has something to do with the lens coatings that are
popular these days? What are the best lenses to buy? I'm
interesested in maximum clarity, I'm thinking of going with just a
plain lens, no anti glare coatings or such.

thanks,
Mark
