So, I was just sitting in the sun, which is already getting stronger and stronger as spring is on its way. I don't wear sun glasses and I was wondering if when keeping one's eyes closed the eye lid is enough to protect the eyes when the sun hits the face directly at a 90° angle.

I am not talking about the eyes as such. I know the sun is dangerous when too much enters the eyes. I am talking about the eyelids. One often sees people tanning on sun loungers, of course they have their eyes closed, but is that enough? That is my question.

No, if you must use a tanning bed at all, then you need to buy the small goggles that they sell for $5-10.
All that makes me wonder, why early humans did not suffer from such problems. They lived in Africa, where the sun is even stronger than for instance here in southern Portugal. Humans didn't have sunglasses for the longest time. Those were invented by the Chinese in the 12th century.
Sometimes I think we might be overprotecting these days, thanks to all the scare mongering by the industry.
They said the other day that many Portuguese (can you believe it) have vitamin D deficiency because they use too much sun blocker. The skin needs unprotected sun exposure every day.
Early humans didn't live 1/2 as long as we do today.
