Combats the Evolving Threat of Indoor Lighting

The benefits of the novel BluTech lenses have recently received the attention of the ophthalmic community. Fluorescent and LED lights are replacing the incandescent bulb with a spectral curve peaking early in the blue wavelengths, dropping off, and providing moderate light in the middle of the visible light spectrum.

Blu-Tech lenses worn under indoor fluorescent conditions filter light below 500nm, with transmission starting in the non-harmful green zone of the spectrum.
