Each GUNNAR lens tint has a specific use and designation



BLUE LIGHT PROTECTION FACTOR (BLPF™)

The Blue Light Protection Factor is a scale to measure and grade the protection level for the eyes provided by lenses from damaging (HEV) Blue Light and UV Light. The BLPF scale ranges from 0 up to 100, which corresponds directly to the amount of Blue Light being blocked – the higher the number the better. The BLPF is about lens protection of the eye as Sun Protection Factor (SPF) is about sunscreen protection of the skin.

A scale to measure and grade the protection level for eyes from Blue Light and UV Light. Wearing a lens with a 65 BLPF means that the lens blocks a minimum of 65% of incoming blue light (from 380 to 450nm) and 99% of UV Light.



AMBER – BLPF 65, BLOCKS 65% OF BLUE LIGHT

The signature Amber lens tint offers the best enhancement of contrast and visual performance while minimizing screen glare, and diminishing the harshest parts of the color spectrum. Our signature Amber lens tint filters 65% of harmful high-intensity blue light and 100% of UV light.

LIQUET – BLPF 35, BLOCKS 35% OF BLUE LIGHT

The GUNNAR Liquet lens is the in-between solution for those who need a balanced color spectrum as well as protection from artificial blue light. The GUNNAR Liquet lens blocks 35% of artificial blue light without the tint so your creativity won’t be inhibited, and your eyes will feel much more relaxed at the same time.

CRYSTALLINE – BLPF 10, BLOCKS 10% OF BLUE LIGHT

The Crystalline lens tint is designed specifically for graphic designers, video/film editors, and creative visual artists who require an equally balanced color spectrum. If your profession requires you to work in true color, then this lens option is for you. The Crystalline lens filters 10% of harmful high-intensity blue light and 100% of UV light.

OUTDOOR – BLPF 90, BLOCKS 90% OF BLUE LIGHT

Our Outdoor lens tint helps enhance your outdoor experience when you’re spending time away from home or the office. When you need to go outside and face the sun’s harsh ultraviolet rays, you need the GUNNAR Outdoor lens. The Outdoor lens filters all harmful UVA and UVB light and is specifically tuned to help improve your circadian rhythm by harnessing the benefits of long-wave blue light.



Blue light, which is part of the visible light spectrum, reaches deeper into the eye and its cumulative effect can cause damage to the retina, Cataracts, disrupt melatonin production, and is implicated in the development of age-related macular degeneration (AMD).

Wearing a lens with a BLPF value of 65 means that the lens blocks a minimum of 65% of the incoming blue light (from 380nm to 450nm) and 99% of UV Light.
