How do you choose the right lenses?
A higher prescription and a higher price do not always mean a lens is better for you.
When choosing lenses, focus on your prescription, frame size, budget, and daily needs.
A simple rule:
Higher refractive index = usually thinner lenses, which are better for stronger prescriptions.
But higher index lenses also usually cost more.
Quick guide:
0–300 degrees: 1.56 / 1.60
300–500 degrees: 1.60 / 1.67
500–700 degrees: 1.67
700+ degrees: 1.67 / 1.74, depending on frame size
Also keep in mind:
Bigger frames can make lens edges look thicker
Strong prescriptions should avoid oversized frames
1.74 is not always the best value
Don’t only look at thickness—clarity, durability, and price matter too
The best lenses are the ones that fit your eyes, frames, and needs.
