I have been having a little problem for a number of years and I am wondering if this issue affects others also.... and how they have (or have not) solved it.
I am basically blind as a bat... and have worn glasses since I was a really young child. As I have ...... ahem.... "matured"
I have a nice set of bi-focal "reading" glasses that I have had made up that I now use in the studio a lot of the time. I had the optometrist set the focal distance for the upper part for the distance to my wheelhead and the lower part for a closer in distance that fits my handbuilding and decorating needs. This works really great for me.
The problem here is that I find that both the distance and the "reading" glasses consistently get scratched all to heck in only about a year's time. I have tried every "scratch resistant coating" that Pearle Vision has available ....to no avail. In fact, the difference between a lens with scratch coating and one without does not seem to make a difference to this.
I am ASSUMING here that the issue is realted to the abrasive qualities of ceramic dusts I am exposed to.... but it is also possible that is NOT the genesis of this issue. But I THINK it must be.
I'm not exactly "Pigpen" in the studio... as my college students can attest.... being the "health and safety" nut on campus (many years as the chair of the college Health and Safety Committee). My home studio is kept pretty darn clean compared to all too many I have seen. I have local pickup ventilation for the major dust making operations, general duilution ventilation, and a ceiling mounted HEPA filter unit (for only when I think it might really be needed). I am constantly conscious of dust making activities...and try to minimize them.
When I clean my glasses, I typically rinse them off under clean running water before I do any "wiping" of them with a tissue or a cloth. I am very "conscious of the whole eyeglass issue... and try to make sure that I am not grinding excessive clay dust into the lens. In fact I typically cannot "see" any obvious dust sitting on the lenses when I clean them about 95% of the time. But still it keeps happening.
Is this just a "cost of doing business" and others are experienceing this same problem also. Or is it a Pearle Vision lens quality issue...and I should shift to another company's product? (My optometerist is located next door to Pearle Vision....conveninet.)
I REALLY do not want to have to go back to the heavier "glass" lenses (they did not exhibit this issue). But these glasses are expensive to keep replacing!!!!!
So I am very curious if it is just me or if other eyeglass wearers are finding the same kind of thing. Thanks.
best,

PS: Shifting to contacts is not an option...... perscription issues as well as highly sensitive eyes.
