Prescription glasses are basically just chunks of not-too-special plastic that you can buy online for $20 or less, but people refuse to believe that the whole industry is a scam when I try to tell them about it
Btw Zeiss (known to HNers for making EUV lithography hardware) also makes glasses and you can buy them online. Some of their lenses are $700. Not worth it for me, but I can definitely see how someone would be willing to pay even more for those optical specs
One is SV AS +2.5 sphere 0 cyl duravision platinum uv 1.60 index (guess this is what you’re talking about) uvprotect
The other is the same but 1.25 sphere
Hope it helps
Don't scratch them. It's simple as that. Wash lens with soap. It's as simple as that.
You can choose the material you put into them. Ray-Ban Scamglasses from the Scam Shop are definitely NOT better. Even Costco glasses aren't better.
Anything insurance touches becomes expensive, because insured individuals are no longer price sensitive, so there is no incentive to lower costs by providers.
My employer pays for my vision insurance, whether I want it or not, so I may as well maximize the benefit with the "best" hardware I can get for "free."
And buy the glasses at Zenni et al.
Likewise, store bought lenses are available with $20 out of pocket expenses.
