Wikipedia says that the heating from the focused light is minimal because the retina is surrounded with fluid, similarly to how a balloon filled, even partially, with water won’t pop over a candle flame. However, the light itself is damaging, as far UV is ionizing radiation and can rip apart the molecules making up your cells.

Ever fry an ant with a magnifying glass?

Swap out the ant for your retinas, and that’s pretty much the deal.

There is physical damage of heating the retina with focused light, and there is chemical damage of depleting the reactions that normally occur when light is translated into neural signals in the retina.

It’s too bright and your lens focuses that light on your retina. Like a magnifying glass focusing the sun on a leaf and setting it on fire.

But my eyeball has never set on fire when I looked at the sun?

On a related note, why is it that looking at the sky when there’s a lot of light, if I use both eyes it hurts, but if I keep one closed I can see the sky just fine?

That’s actually a bug; your brain averages light levels across both eyes when deciding how much to flinch.

Don’t do it - you’re basically exposing yourself to potentially damaging light levels in the eye you keep open.

I’m not sure, it doesn’t matter which one I close

Pure conjecture, but maybe one overloaded eye is easier to handle than two?

Rules (interactive)

That’s it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it’s in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.

Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.
