I used to work for LensCrafters and I can tell you for a fact that they make a big deal out of wanting as many customers as possible to want to get contacts. Every meeting there was a reminder that we were to push contacts. Hell, the other employees /managers repeatedly tried to push contacts on me even after I informed them that there was no way that I would ever shove a piece of plastic into my eye.

To them, the difference between selling glasses and getting a customer to sign up for contacts is like the difference between selling a video game and getting a player to get a monthly subscription.  And failing that their next big sell is for frames that cost twice to three times as much, but have little to no frame (and thus almost look like you aren’t wearing glasses at all) and are fragile as all hell (and thus are likely to break and have to be replaced).

They can’t rely solely on our prescription getting heavier or otherwise changing to the point that we have to buy a new pair every year. They want to push you to buy their product every time that you visit the optometrist and then some more in between.

As counter-intuitive as it might seem, it is in Big Optic’s best interest to convince us that we look terrible if we wear glasses.

The next time you need an eye exam, ask for a copy of your prescription. Take a picture too.

You can buy prescription glasses and even prescription sunglasses online for a fraction of the cost as they will force you to pay in stores.

The only thing you need is your prescription, and your pupil distance, which you can just measure at home

Firmoo.com

Eyebuydirect.com

I forget the other ones but these are the two I've used. Firmoo always has a lot of coupons and buy one get one free deals.

If you buy them online, you can get prescription sunglasses for $30. If there's a buy one get one sale, you can get two pairs of prescription sunglasses for $30. And they don't have to be the same prescription. You but yourself prescription sunglasses for $30, and you can get somebody else a pair of prescription sunglasses for free. Or just a backup set if something happens to the first one!

Seriously!

You do not need to be spending $60 on glasses!! Buy them online!!!

It also means that if you break them catastrophically, you can just reorder them online instead of having to go to the eyeglasses place, which would suck even more for you if your eyes are so bad that you can't drive.

I use zennioptical.com for my glasses, which is how I got the heart shaped ones

This is all true but it's actually because it's difficult to film people wearing glasses - they reflect the set lights and camera and stuff. So it's easier not to bother. Most times I've been filmed, doing any sort of head shot/speak to camera stuff, the camera operator has had me take mine off.

Knives Out went to ridiculous lengths to allow the actors to wear glasses, sculpting different light diffusers so the reflections would be natural and everything
