Should I get UV and blue light protection glasses

Without at least 97% UV protection, framed pieces can age and fade more rapidly. Indoor and outdoor UV light rays contribute to severe color loss, paper embrittlement and deterioration of framed pieces. These effects are both cumulative and irreversible.
Is 100% UV protection in sunglasses enough
Sunglasses are more than just a fashion accessory, they are very essential for safeguarding your eyes from the harmful effects of UV rays. That's why 100% UV protection sunglasses are a must-have when stepping out into the sun, even for a short period of time.
Does UV protection make glasses darker
Photochromic lenses are the type that darkens gradually when exposed to sunlight, and return to normal when you go back indoors. UV coating alone does not provide this color change. UV rays are invisible, and UV coating does not block out visible light.
Is UV protection the same as SPF
SPF stands for “Sun Protection Factor”. It measures the amount of time it takes for sun-exposed skin to redden, while UPF measures the amount of UV radiation that penetrates a fabric and reaches the skin. Remember that SPF only accounts for UVB rays unless specifically stated as a broad-spectrum sunscreen.
Does UV damage eyesight
Prolonged exposure to UV rays modifies lens proteins, leading to cataract formation and worsening eyesight. Over time, cataracts can make vision blurry, hazy, or less colorful. Cancers of the eyelid, including basal cell carcinoma and squamous cell carcinoma, are linked to UV exposure.

How long does UV protection last on glasses
Because sunglasses lose UV protection the more you wear them in the sun, the answer to "how often should you replace your sunglasses" depends on how frequently you wear them. If you find that you wear your sunglasses about two hours a day, you should replace them every two years.
Is SPF 50 better than SPF 70
While any sunscreen is good because it protects your skin from UV exposure, SPF 70 only protects your skin from less than one percent more UVB rays than SPF 50 does.
Is SPF 30 lighter than SPF 50
An SPF 30 allows about 3 percent of UVB rays to hit your skin. An SPF of 50 allows about 2 percent of those rays through. That may seem like a small difference until you realize that the SPF 30 is allowing 50 percent more UV radiation onto your skin.
How long does it take for UV to damage eyes
eight to 24 hours

Is UV 400 same as 100% protection
To be considered UV sunglasses, the lenses are required to block 75% to 90% of visible light and must offer UVA and UVB protection to block 99% of ultraviolet radiation. Ideally, you want sunglasses that offer UV 400 protection since they offer virtually 100% protection from UV rays.
Why not use SPF 50
High-SPF products might give you a false sense of security.
One potential problem with using super-high SPF is that it might backfire and lead to more UV exposure. "In real life, products with very high SPF often create a false sense of security," dermatologist Dr. Stephen Q.

The Skin Cancer Foundation recommends a water-resistant, broad-spectrum sunscreen with an SPF of 30 or higher for any extended outdoor activity.
