On a related note, anyone wearing prescription glasses will be affected by chromatic aberration to some degree, which may notably cause the blue portion of the image to be shifted relative to the rest of the image, which makes text and other detail harder to see and can be annoying. This effect is accentuated when looking at a strongly trichromatic source like a computer or screen because the spectrum is discontinuous and the blue content has more power at shorter wavelengths than most natural sources.

You can mitigate this by using lenses made from a material with a higher Abbe value. Polycarbonate is the worst, CR-58 is the best, and Trivex is quite good. Trivex is also impact resistant, so it’s an excellent alternative to polycarbonate. The high-index plastics are quite bad, so if you don’t need them, consider asking for mid-index or Trivex instead.
