- Do these glasses actually reduce eye strain?
- Blue-light filtering lenses help some people feel less tired after long screen sessions, but research on the effect is mixed. They do not replace breaks or treating dry eyes.
- Can I put a prescription in these frames?
- They ship as non-prescription glasses. An optician can sometimes reglaze a full-rim frame, but check the frame's lens groove and material first, since not every frame takes prescription lenses.
- How do they compare with rimless blue light glasses?
- The full rim protects the lens edges and feels more durable, but it weighs more and shows more frame on the face. Rimless pairs are lighter and less visible.
- Will the tortoise pattern match my face?
- Brown speckled tortoise is a warm neutral that flatters most skin tones. The rectangle shape is widest at the brow, which balances round and oval faces.
- What comes in the box?
- Usually just the glasses. Cases and cleaning cloths are often sold separately, so confirm before ordering if you need them.
- Are they good for driving at night?
- Blue light glasses are aimed at screens, not headlights. For night driving, look for lenses with an anti-reflective coating instead.
