How to Choose a Lens Strength

For lenses that offer multiple strengths, our standard strength tint is most popular. The overall tint of the lens is 35%. It balances protection from the most problematic wavelengths of light with a lens that is comfortable to wear.

If you know light bothers you a lot or you are very sensitive to it, our extra strength tint is a good option. For people who are exceptionally sensitive to light, we offer max strength, though we generally recommend starting with a lighter tint first.

Note, if you have photosensitive epilepsy, we recommend TheraSpecs Z-Blue™ in max strength. That is the only strength that has been studied for this condition.

Whatever tint strength you choose, please let us know if it doesn’t meet your needs. We make exchanging for a lighter or darker tint easy!
