Do these glasses actually reduce eye strain?

Gunnar's amber lenses filter blue light and add slight magnification, and many owners report less fatigue after long screen use. Results vary, and the tint does not replace breaks or proper monitor distance.

Can I wear them for photography or design work?

Not ideal. The amber tint shifts colors, so whites look warm and color-critical work is affected. Use them for reading and general screen time instead.

Are the lenses prescription?

The standard Campbell comes with non-prescription lenses. Gunnar offers prescription versions of some frames, so check the specific listing if you need a prescription.

How do they fit different face sizes?

The round-oval metal frame is unisex and fits most medium faces. The nose pads can be adjusted, but people with very wide or very narrow faces should check the frame width.

How do I clean the lenses?

Use the included cloth and a lens spray, and avoid paper towels or clothing, which can scratch the coating. Clean both sides of the lens to remove smudges.
