Do I really need to use special cleanser for my new lenses, or is the company that made them just trying to get me to spend more money?
This week, I got a new pair of glasses from Pearle Vision
. They applied an "anti-reflective coating" to the lenses, which is supposed to reduce the glare from my computer screen and that sort of thing.
When I went to pick up the glasses, the salesperson handed me a stack of these pre-moistened towelettes
and told me to wipe the lenses down with them before
I used the soft cloth to clean them. She warned that if I cleaned them without using a towelette, I risked scratching the anti-reflective coating.
Conveniently, these little towelettes are sold at Pearle Vision. I think the price is $10 for 21 of them. At the rate at which I smudge my glasses, I probably need at least one a day. I did the math, and that's $180 annually (if I'm really judicious) on special cleaning cloths.
So my question is: does anyone have any experience with this? Will it really scratch up the lenses (or, I guess, the coating)? Or will a soft cloth suffice and they're just trying to get more money out of me?
The only thing I could find via Google was this, wherein one man complains that his wife's lenses were indeed scratched within six months, and they blamed it on her not using their cleaning supplies. (That, and a lot of complaints about their customer service, which makes me feel a little less alone in my bitterness toward them.)
