It still blocks a majority of visible light, and is an excellent choice for morning, evening or partly cloudy days, or anytime light conditions are constantly changing. 5.The Yellow Lens is the trickster of the Competition family. It blocks about 85% of the sun visible rays, but it plays a trick on the brain by actually making things seem brighter.

They are fantastic for dark, cloudy days, indoor sports, or under artificial lights where physical eye protection is desirable.
