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, our extra strength tint may be a good option. For people who require even more protection, we offer max strength, though we generally recommend starting with a lighter tint first.

Note, if you are living with photosensitive epilepsy, we recommend adding TheraSpecs Z-Blue™ in max strength to your light management toolkit in order to filter the harsh wavelengths from flashing or strobing lights and/or repeating patterns.

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!
