A subtle cat-eye shape with soft, round curves makes this unisex frame an easy crowd pleaser. STYLE THAT ADDS UP ? Felix Gray?s Lovelace is a great fit for any face and has a crowd-pleasing look, with a subtle cat-eye shape and soft, rounded edges. WHY FILTER BLUE LIGHT ? Filtering Blue Light and eliminating glare may help to combat Digital Eye Strain. Blue Light is emitted by most modern, digital devices, and may be linked to eye strain, sleep cycle disruption, and potentially macular degeneration. Glare creates unnecessary feedback that enters into our eyes and can cause it stress. THE FELIX GRAY DIFFERENCE ? Felix Gray?s proprietary filtering technology is embedded directly within lenses, so 50% of all Blue Light and almost 90% of the highest range are filtered out. Premium anti-glare and UV protection are also applied, with no blue-reflective coating and an unnoticeable tint. TOP-LEVEL QUALITY ? Hand-finished Italian acetate frames with proprietary lenses make Felix Gray?s Blue Light blocking computer glasses a must-have. RIGHT SIZE FOR YOU ? Lovelace is a medium width frame and has measurements of 51-15-135. This corresponds to 51mm lens width, 15mm nose bridge width, and 135mm arm length.
