What strength glasses should you pay for thinner lenses
9 Answers
Hi, I have -2.75 power lenses and I am getting thick Wayfarer style plastic frames. Should I pay the extra £40 to get the 1.6 thinner lenses or is it not worth it with only -2.75 power?

My prescription is so strong, that even with Zeiss lenses i am restricted to the type of frames that will support my lenses.
I am of the opinion that if you wear something throughout your waking hours, you should get the best you can. if you compare it with the price of a car, which you drive some of the time, it makes good sense to have the best glasses you can afford - and get them insured, very cheap, but worth it if anything happens to them.

I agree, and wear 1.67 varifocals, But to assume that a lens is better just because it has a higher refractive index (and is therefore thinner) is not correct. The higher the index, the higher the chromatic aberration. So if you can get a decent thickness at a lower index, you are better off saving your money.
