my lenses are like a plastic kinda material, but they also aren’t very strong. maybe glass lenses are, and that’s why they’re used? perhaps i’ll find out when i go back to the eye doctor (i need stronger lenses :[ )
Glass doesn’t scratch as easily, and it has a different refractive index so a stronger prescription might be thinner in glass…
They area lot heavier though.
People still make glasses out of glass?
Yeah, some still do.

No, plastic lenses are less fragile than glass.
sorry, i did not mean “strong” as in physical strength. i meant perscription strength
Plastic is capable of stronger prescription strength in a thinner lens than glass.
ah, i see*, i am entirely wrong.
*no, i can’t really
