KEI Lenses
Precision-engineered lenses, made for you
Standard
100% UVA/UVB protection with premium anti-reflective and anti-scratch coatings, precision-ground to your exact prescription. Blue light filtering can be added to this lens.
Thin
Our 1.67 high-index lenses are thinner and lighter — ideal for stronger prescriptions. Includes 100% UVA/UVB protection and premium anti-reflective and anti-scratch coatings. Recommended for prescriptions stronger than -4.00 and +4.00. Blue light filtering can be added to this lens.
Non-Prescription Blue Light
They filter harmful HEV blue light from digital screens and artificial lighting, with 100% UVA/UVB protection, premium anti-reflective and anti-scratch coatings, and a hydrophobic coating that repels water, oil, smudges, and dust — keeping your lenses cleaner for longer.
