Do sunglasses work? Or they also don't work because some light still goes through?
Asking for a friend.
Discussion
Depends.
They block UV rays, or they should anyway. If they don’t you need better glasses.
That said, your eyes need sunlight to help them focus, particularly early AM sunlight.
So, depending on how you use them you’re helping or hurting
Are you saying UV light is like spam for the eyes and gets filtered by the sunglasses?
Spam for the eyes?
No, but yes it’s filtered.
Okay, I am saying it.
UV light can cause several serious eye conditions, including cataracts, pterygia ("surfer's eye"), and macular degeneration. These chronic effects develop over time and can lead to irreversible vision loss. UV exposure can also cause short-term, painful photokeratitis ("snow blindness").
Sure, but it’s nuanced.
If the only sun you get is an hr a day, probably not an issue.
If you’re getting blinding sun bounced back directly into your eyes from water, or other exposure, yes, it can damage your eyes over time.
It’s like shining a magnifying glass onto a camera lens, it’s going to break if done for too long.
They are a shitcoin, removing the information hidden in light necessary to live healthy.
The shitcoin ones are the ones that let everything through. They don't work.
The ones that work filter UV.
