Do these actually block blue light?

Yes. The polycarbonate lenses are amber-tinted and filter a portion of high-energy blue light from screens. The effect is real but modest; independent studies find blue-light glasses help comfort more than sleep or eye health.

Will the amber tint affect my work?

It will. Colors look warmer and less accurate through the lenses, so they suit gaming and general screen use better than photo or video color grading.

Can I get these with a prescription?

This model is sold as non-prescription. Gunnar offers prescription versions of some frames, but the COD Tactical as listed here is plano only.

How do they compare with clear blue-light glasses?

The amber lenses filter more blue light than clear coatings, at the cost of color shift. Clear lenses are better if you need accurate colors and only want mild filtering.

What comes in the box?

One pair of glasses in Gunnar's packaging set. A cleaning cloth and case are typical of Gunnar's retail packaging, but check the listing for the exact contents.

Are they good for people with sensitive skin?

The nylon frame is hypoallergenic, which helps if metal frames irritate your skin. Nose pads still touch the skin, so fit matters.
