Adjustable Focus Range

These sunglasses provide a variable diopter range from -6.00 to +3.00, allowing the wearer to dial in the exact correction needed for reading or distance vision. The single pair replaces multiple prescription glasses for everyday tasks. They suit adults who want one frame that adapts to changing focal demands without switching eyewear.

Frame Fit and Portability

The black ABS frame measures 18 mm at the bridge and 133 mm along the arms, delivering a lightweight fit that folds flat for pocket storage. Impact-resistant polycarbonate lenses handle daily knocks while the scratch-resistant coating keeps vision clear. No special case or tools are required to adjust the focus dials.

Optical Clarity and Durability

Polycarbonate lenses block glare with a black tint while maintaining impact resistance for active use. The adjustable mechanism operates smoothly without adding noticeable weight or bulk to the frame. Scratch resistance protects the optical surface during regular cleaning and transport.

Questions about this item

How long do the dial mechanisms stay accurate when I keep changing focus all day?

The self-adjusting lenses use a manual dial system with no batteries or electronics, so there is no power drain or drift; accuracy depends only on the mechanical detents holding position.

Do the frames get hot or uncomfortable after hours of wear in sunlight?

The ABS frame and polycarbonate lenses are lightweight and do not conduct heat noticeably; no active cooling or power draw means temperature stays close to ambient.

What bridge width do I need on my face for these to sit correctly?

The bridge measures 18 mm (0.7 in), so your nasal bridge should be near that width for a secure fit without slipping.
