SHINU | SHINU Orange Lens for Long Time Working Gaming Eyeglasses Anti Blue Light Glasses Red Lenses Better Sleep Y2k Glasses

There are mainly four types of anti-blue light lenses: transparent, yellow or orange, and red. Red lenses can block 100% of blue light. Wearing them before going to bed can help with sleep, but they have a low light transmittance and the light is relatively dim. It is recommended not to wear them for more than two hours.Orange lenses can block 99.5% of blue light and are suitable for wearing when playing computer games or working for a long time. They offer a good experience and protect the eyes. Yellow lenses can block 78% of blue light. They also have other functions: night vision. Because they are better for driving, we use polarized lenses for yellow lenses. They are very effective when driving at night. Transparent lenses can block 18% of blue light. They do not affect any colors, and the scenes you see are the same as when not wearing glasses. We use the same material as prescription lenses. C1 GREY PEAR WOOD FREAM.
