Reviews
Questions and answers
- Which is better for long gaming sessions?
- The GUNNAR Berkeley is the safer pick. It is built for gaming, comes in a wide 137 mm frame and reviewers report less eye strain over long sessions. The Spektrum is a plain amber pair with no gaming-specific design.
- Does the Spektrum block more blue light?
- Spektrum states 99% blue light blocking. GUNNAR says its lenses block harmful blue light and 100% UV but gives no blue light percentage, so the two figures are not directly comparable.
- Can I get either pair with a prescription?
- Only the GUNNAR Berkeley. It accepts prescription lenses, ready in 2–7 business days. The Spektrum has no diopters and is non-prescription only.
- Which has the clearer lens?
- The GUNNAR Berkeley, if you pick the clear tint. Its clear lenses avoid the yellow cast of amber lenses. The Spektrum comes only in amber, which shifts colors.
- Which is lighter to wear all day?
- The GUNNAR Berkeley is likely lighter. Its nylon frame is described as lightweight. The Spektrum weighs 6.4 oz (181 g), which is heavy for glasses.
- Is the GUNNAR worth the extra cost?
- No prices were given for either pair, so compare them on Deal.ai. The GUNNAR adds prescription support, UV protection, a clear lens option and a known brand, which the Spektrum lacks.
