Gunnar Technology Eyewear MATEO

The GUNNAR Mateo Blue Light Glasses use a premium, lightweight titanium frame, weighing only about 15.9 grams without packaging — one of the lighter builds in GUNNAR's lineup. Titanium is generally valued for being both strong and light, which can make a difference in comfort during long periods of wear.

The GUNNAR Mateo Blue Light Glasses have a keyhole bridge with adjustable nose pads, letting you fine-tune how the frame sits on your nose. This is paired with high-quality German spring hinges, which are meant to give a more customizable, secure fit than a fixed frame.

Asian-fit compatible on the GUNNAR Mateo means the frame's bridge and temple design is built to fit face shapes with a lower nose bridge and higher cheekbones more comfortably than a standard Western-fit frame. This is in addition to the adjustable nose pads for further fit customization.

The GUNNAR Mateo Blue Light Glasses measure 52mm lens width, 43mm lens height, 20mm nose bridge, 135mm frame width, and 135mm temple length, weighing about 15.9 grams. These relatively compact, lightweight dimensions are part of why the frame is marketed as subtle rather than oversized.

Yes, the GUNNAR Mateo Blue Light Glasses are available in prescription lenses. They ship with a tri-fold glasses case, a microfiber pouch, and a microfiber cleaning cloth, backed by a 24-month manufacturer's warranty — longer than the 12-month coverage on many other GUNNAR frames.
