There is an article that confirms what most people suspect:
Alternet: Wow -- the Eyewear Industry Is an Incredible Ripoff, But There Are Alternatives
Eyeglasses are an artificial ripoff because one corporation, Luxottica, based in Milan, Italy has a global vertical monopoly on much of the manufacture, retailing, insurance and and licensing of eyeglasses causing high artificial markups.
That article mentions several websites that sell outside of the Luxottica monopoly for much less. I personally went with ZenniOptical:

But they also mention:

https://www.goggles4u.com/

I got a hookup since my bro works at a retina specialist who gave me a free eye exam. I decided to order memory Titantium glasses(the kind that can bend around your finger and snap back to remember its shape:

Frame 210121 $12.95
Color
Prescription Type Single Vision
PD-Pupillary Distance 65
Lens 1.59 PC(Polycarbonate, this is an extra meaning that the lens cannot shatter) Single Vision $9.00
AR Anti-Reflection Coating Anti Reflection Coating (another extra too cheap to pass) $4.95
Extra Strength Charge (This is extra charge is because I choose memory titanium I think) $16.00
Unit Price $42.90
Quantity 1
Sub Total $42.90
Subtotal $42.90
Shipping & Handling $4.95
Grand Total $47.85
They still have not arrived as it could take up to 2 weeks, but I am excited. I do alot of active stuff like mountain biking, kayaking, running at times and eventually after years glasses fall down, you have to adjust the frame to fit your face, etc. The frames come to get bent out of shape and look asymmetrical no matter what adjustment you happen to make. Not only are these dirt cheap(I believe memory titanium is $300+ retail for just the frame), but hopefully years later this frame will still have its proper shape.
