Protan-Specific Outdoor Lens

These glasses correct protan colour blindness, which accounts for about 25 percent of red-green cases. The outdoor lens boosts reds and normalises the red-green ratio so hundreds of hues become distinguishable. Buyers with deutan colour blindness need a different lens type and cannot use this model.

UVA UVB and Blue Light Filtering

The lenses filter out 100 percent of harmful UVA and UVB light and also block blue light. Patented optics refined over more than a decade enhance colour distinction, improve contrast and render whites and neutral tones naturally. No thermal, noise or power metrics apply to this passive optical accessory.

Cellulose Acetate Frame With Spring Hinges

A cellulose acetate and stainless steel frame moulds to various face shapes while adjustable nose pads and spring hinges flex for a secure fit that adapts over time. Water-repellent coating helps keep lenses clear in outdoor conditions. This accessory is not suited for indoor screen work or low-light environments.

Questions about this item

How do I adjust the spring hinges and nose pads for the first fit, and what step is often missed?

Bend the adjustable nose pads gently until the frame sits evenly on the bridge, then flex the spring hinges outward so the temples hug the head without pressure; the step most people skip is re-checking the nose pads after the hinges settle.

What part of these glasses will need replacement first with daily outdoor wear?

The water-repellent and blue-light-blocking coatings on the Outdoor Protan lenses degrade before the cellulose acetate frame or stainless steel hinges, so plan to replace the lenses when color saturation noticeably fades.

At what point does the Protan lens stop boosting reds effectively during prolonged bright sunlight?

The lens corrects the red-green ratio continuously while UV intensity stays within normal outdoor levels; extreme glare beyond typical daylight can reduce the saturation boost, but the 100% UVA/UVB filter remains active.
