help Shamir Blue Zero FAQ
Is Shamir Blue Zero a coating or part of the lens?
Blue Zero protection is embedded in Shamir's polymer lens material rather than existing only as a surface coating. An anti-reflective treatment can still be added separately by the dispensing laboratory.
How much blue light does Shamir Blue Zero block?
Shamir materials describe absorption of up to about 50 percent of HEV light in the 405 to 435 nanometer range. The actual percentage can vary with lens index, prescription, and thickness.
Can Shamir Blue Zero be made with a prescription?
Yes, Shamir markets Blue Zero for both prescription and plano lenses. Availability depends on the requested lens design, refractive index, and the optical laboratory supplying the glasses.
Will Shamir Blue Zero lenses look yellow?
They are designed to remain substantially clearer than strongly amber-tinted blue blockers, though a slight residual tint may be visible. Shamir specifically positions the material as preserving contrast and normal color perception while filtering a limited HEV band.
