You might not go blind by staring at the Sun, but please don’t test it! It’s possible, but the hazard is often exaggerated. Even at midday, a normal eye will only let in enough light to heat the retina by about 4°C. You need at least 10°C to cause thermal damage.

Can you go blind from staring too long?

According to Dr. Arvind Saini, an ophthalmologist affiliated with Sharp Community Medical Group, extensive screen use has its downsides, but blindness isn’t one of them. “There is no clinical evidence that prolonged screen use causes permanent vision loss,” he says. “Dry eyes and eye strain, yes.

But what you might not realize is the number of ways the sun can damage your eyes.

• It can increase the risk of eye cancers, including on the eyelid.
• Too much sun exposure can lead to cataracts.
• Prolonged sun exposure can lead to growths on the eye.
• It can lead to macular degeneration.

What happens if you stare at the sun for 10 seconds?

It destroys the rods and cones of the retina and can create a small blind spot in the central vision, known as a scotoma. The retina does not have any pain-receptors, so you won’t feel the damage being done.

Can sunlight damage your eyes?

Your eyes can be damaged from ultraviolet rays. In particular, UV-A and UV-B rays from the sun can cause short- and long-term damage to your eyes and affect your vision. Although the sun also emits UV-C radiation, those rays are absorbed by the ozone layer and don’t damage your eyes.

What happens if you accidentally look at the sun?

First, staring directly at the sun can damage a part of the retina — which is responsible for the center of your vision — causing a condition called solar retinopathy. Solar retinopathy is like a sunburn on the retina, a layer of tissue at the back of your eye, Habash tells BuzzFeed Health.

How long can you stare at the sun?

Permanent retinal damage can occur when someone looks at the sun for 100 seconds or less. This is under two minutes. Ultimately, how long it takes for damage to occur depends on several factors, such as the dilation of the pupil and the sun’s intensity on that specific day.

What happens if you look at the sun for 5 minutes?

How long does it take to go blind from staring at Sun?

That being said, under optimal viewing conditions (midday sun and clear skies) you can easily be temporarily blinded within a minute of staring at the sun. It may take days or weeks before the cells repair themselves and some retinal scarring may occur, slightly impairing your vision for the rest of your life.

What happens to your eyes when you stare into the Sun?

The damage is mainly done to the retina, which is a “layer at the back of the eyeball containing cells that are sensitive to light and that trigger nerve impulses that pass via the optic nerve to the brain, where a visual image is formed.” By staring into the sun, the strong rays burn those nerves in your eyes, and nerve damage is irreversible.
