If you end up getting a prescription set. Look at zenni optical. Yeah a its fucking chinese company...
If you think the glasses you are going to buy at the optician are special, you should look into that iondustry, 2 companies, and everything is made in China.
Zenni can get you the cheapest pair of prescription glasses for 7 bucks or so, addons (polarization, transitions...) cost more just like at the optician.
I wore glasses till I got lasik and I used them extensively, had enough pairs of glasses lying around that I could change them with my clothes they were cheap enough. The only issue I ever had, was their frameless designs, feel like coke bottle think compared to other designs.
