My glasses are a few years old and I can't remember if they came with UV protection/UV coating or not.
I do not remember the name of the lenses but I bought them at Wal-Mart and they are definitely nothing fancy.
Because I want to protect my eyes, I want to take them to a store and (if possible) add UV protection.
Can a UV coating be added to existing lenses for glasses or would it have to be done when the lense was actually being manufactured?
Hopefully I can take in my glasses and get this added.
Of course there's the obvious answer of calling up some shops. Since I'm staying in Bangkok now there's a bit of a language barrier. Before I venture out to some shops I would like to know if I'm wasting my time in even trying.
Thanks in advance.
