The optometrist recommended seamless bifocals. I have a very painful nerve condition in my face (atypical trigeminal neuralgia), so this is what I need with glasses: the lightest weight frames possible- known as ultra light- with the lightest weight lenses possible and automatically darkening lenses so I don’t need the weight of sunglasses. The cheapest frames brought the total to $250 on the site the insurance worked with.
The frames are $20 on the cheap site. Everything else in the cost is the lenses.
As for why I have to buy them online- I don’t want anyone touching my face unless it’s absolutely necessary. The exam was painful enough.
American for-profit healthcare is fucking awesome.
I always go for sprung hinges with Zenni. I’ve never need to tighten the screws with those.
Used them for years with no issue and get lots of pairs for distance, reading, daytime driving (polarized sunglasses bifocals so no glare and I can see the instruments), etc.
