Precision Lens

Precision Lens Technology

Short-wavelength, high-energy blue light rays in the 450 to 495 nanometer range penetrate the light sensitive retina in the back of the eye. The remaining visible light spectrum is filtered at the lens of the eye.

Bullhead precision lenses block blue rays, which reduces eye strain, increases visual acuity and protects from the long-term effects of blue light exposure.

Short term exposure to blue light rays causes eye-strain, and long term exposure causes retinal damage which contributes to macular degeneration.
