Are these glasses worth it for screen work?

They are a low-cost way to try blue-light filtering in a light frame. Evidence that blue-light lenses reduce eye strain is mixed, so treat them as one part of screen breaks and good lighting.

Can I order them with my prescription?

Yes. Cyxus lists these as prescription glasses with polycarbonate lenses. You will need your current prescription, including pupillary distance, at checkout.

Will the 140 mm frame fit me?

A 140 mm frame width suits most average adult faces. If your current glasses are narrower than about 135 mm, these may feel loose.

What is included in the box?

Cyxus typically ships the glasses with a case and cleaning cloth. Confirm the exact contents on the store listing before ordering.

Do they block all blue light?

No. They filter a portion of blue light and the lenses stay clear. They are not a substitute for sunglasses outdoors.

When is the best time to buy?

Cyxus frames often drop during back-to-school and holiday sales. Check the price history on this page and buy when it sits near the low end of its range.
