If bright lights, glare, fluorescent lighting, LED lighting, or digital screens are visually uncomfortable, Eschenbach Acunis FL-41 glasses provide specialized rose-tinted filtering with three different light-absorption options.
Choose from 25%, 50%, or 75% light absorption depending on your preferred tint level and the environment where you plan to wear the glasses.
Unlike a conventional dark tint that primarily reduces overall brightness, FL-41 filter lenses selectively reduce transmission of certain wavelengths of visible light. Eschenbach's Acunis filters are designed for people experiencing glare and light sensitivity, including migraine-related light sensitivity.
25% Light Absorption – Light Rose
The lightest of the three available tints. A good choice when less overall light reduction is preferred.
50% Light Absorption – Medium Rose
A medium-strength rose tint providing increased light absorption compared with the 25% option.
75% Light Absorption – Dark Rose
The darkest of the three options. Designed for situations where greater light absorption is preferred.
Please select your desired lens absorption from the variation menu before ordering.
