Where to get prescription sunglasses

[All Darc]

I'm forced to tell you that maybe be worth do check with a bas-tard, oops, I mean a doctor, to see if there is anything wrong with your eyes. Just to be sure, since some problems can be detected earlier to treated better, but a self prescription glass could hide a problem until it became too serious.

Medical science helped dogs, but not humans : Years ago they studied a pair of identical chinese twins that borned with congenital cataract, and neither parents had cataract. They checked the genome of the twins and the parents and found out it was a mutation that happend to the twins, since no parents had the mutation. More studies showed that the mutation altered a gene responsible to produce a substance, now not being produced in the eyeball of the twins. They concluded such substance was responsible to keep the eye's crystallin clear. They tested it with intraocular injections on rabbits and dogs, and it worked cleaning well low and meddium degree of cataract, and almost cleaning all in advanced cataract.
So they decided to test in humans, AND IT FAILED !!!

Started with humans DNA research, but only worked in animals.

I've been happy with Zenni Optical.

3-d printer?

I haven't tried it myself but it looks interesting. I've read that this is near impossible to make clear lenses at home but maybe in the future as tinkerers get better at it.

My first thought was 3D printed as well.

What's the use case? Driving? I have a picture of myself wearing my current prescription [aviator frame] dark glasses that was taken in 1995.

I've given up on bifocals, I just take them off for reading and put them on when I leave the house. Them being a 6 or 7-year-old un-tinted pair.

The use case is anytime I'm outside and it's not overcast. I'd really like to play Ultimate someday and have some shades that also correct my terrible vision. Bicycling. Any outdoor activity really.

I drive for a living. Prescription eyewear is no joke.

The rest aside, it’s why I recommend DriveWear. Sun up to sun down if wanted.

And, FB, can’t be distracted looking for eyeglasses while moving. Paying for the bifocal aspect is par.

FWIW, glass lenses are the way to go for most of the day. No yellowing, etc. High Index now available. Permanency.

The right frames are big. Not about fashion. Sturdiness.

And not using one hand.

Driving.

You don't really get what you pay for in frames, but lenses... you get what you pay for in lenses.

I could see that... but at the end of the day, the lenses are merely precision shaped plastic, perhaps with some coatings which I'm probably not too interested in. I'll go with polarization since I spend a fair amount of time on the river. I'd be curious to know what the margins are on the frames, and the margins on the lenses. I have a feeling it's somewhat like mattress prices.

The precision is the expensive part, not the plastic. Or, preferably, the glass.

I'm newish to glasses (2 years), and have never had glass. My understanding is plastic is thinner and lighter, with glass being more durable, and possibly clearer?

Anyhow, I don't have much of a problem with durability of the lens since I don't subject them to scratching, and intend to replace them every couple years (which is why I prefer cheap).
