With enough damage to the retina, though, staring at the sun can leave you partially blind. Prolonged UV exposure can damage the macula
Macula of retina
The macula or macula lutea is an oval-shaped pigmented area near the center of the retina of the human eye and some other animalian eyes. The macula in humans has a diameter of around 5.5 mm and is subdivided into the umbo, foveola, foveal avascular zone, fovea, parafovea, and perifovea areas.
Does the reflection of the sun while driving damage the eyes?
Originally Answered: Does the reflection of the sun (e.g. while driving) damage the eyes? In and of itself, no. Reflected light can make your eyes water, can cause irritation and blurry vision, and has an effect (while driving) called "glare recovery time", which is longer in older people, and those with already existent eye problems.

Why are sunglasses important?
It’s important that your sunglasses protect your eyes from both UVA and UVB light. Children are at a particular high risk of solar retinopathy. Younger eyes may transmit more light to the retina. Children may also not fully understand the consequences of staring at the sun for too long.
How long after staring at the sun do you have retinopathy?
If you experience any of the symptoms of solar retinopathy several hours or the day after staring at the sun, see your eye doctor for an assessment.

The oxidative damage is referred to as solar or photic retinopathy. Damage can occur in as little as a few seconds of staring directly at the sun.
How long does it take for retinopathy to show in one eye?
In most cases, you probably won’t even notice symptoms or vision changes right away, either. It can take up to 12 hours for you to start having symptoms. Symptoms of solar retinopathy can occur in just one eye, but most cases occur in both eyes at the same time.
Why can't we stare at the sun?
Most of us can’t stare at the bright sun for too long. Our sensitive eyes begin to burn, and we instinctively blink and look away to avoid discomfort.
What happens when UV rays are absorbed into the retina?
Once absorbed into the retina, the UV rays result in the formation of free radicals. These free radicals start to oxidize the surrounding tissues. They ultimately destroy the rod and cone photoreceptors in the retina. The oxidative damage is referred to as solar or photic retinopathy.
How long does it take to recover from solar retinopathy?
Recovery is mostly about waiting it out. Symptoms will most likely improve over time, but it can take anywhere from one month to a year to fully recover. Some people may never fully recover their vision.
Where is the diamond ring in the solar eclipse?
This panel shows the various stages of the solar eclipse. The so-called "diamond ring" marks the beginning of totality (third from the left) and the end of totality (third from the right). Imelda Joson and Edwin Aguirre assembled this sequence from individual still frames they took of the March 29, 2006, total solar eclipse near El Salloum in Egypt.

What happens when the sun hits the retina?
When intense solar radiation hits the retinas, it can damage and even destroy those cells , in what doctors call a retinal photochemical injury, or solar retinopathy. Whether looking at the sun will cause this type ...
Why is it so hard to look at the sun?
Under normal circumstances, it's more difficult to look at the sun long enough to incur damage because of something called an aversion reflex.
When should you remove your glasses during an eclipse?
While official recommendations by NASA and the American Astronomical society say you shouldn't look directly at the sun when any part of it is showing, experienced eclipse watchers like Chou say it's safe to remove your eclipse glasses during the 2-3 seconds before and after totality to see the so-called diamond ring effect, or "Baily's beads." During this phase of the eclipse, the light of the crescent sun forms points of light on the edge of the disk for just a few seconds.
Why does the sun burn your eyes?
That's because the light from the sun is so intense that it can literally burn your eyeballs — even during a solar eclipse, when part of the sun's disk is still visible.

How many airmasses are there in the Sun?

Does snow hurt your eyes?
Snow-blindness is an example of how reflected sunlight can hurt your eyes. If you walk outdoors on a very bright day with snow on the ground, especially deep snow with very little else to see, your eyes can get damaged from the UV radiation just like you would if you looked at the sun directly. Bright white snow is very reflective. People who have to spend long periods of time in a snow-covered, sunlit environment need to wear sunglasses or goggles to protect their eyes.
What happens when you stare at the sun?
When you stare directly at the sun—or other types of bright light such as a welding torch—ultraviolet light floods your retina, literally burning the exposed tissue. Short-term damage can include sunburn of the cornea—known as solar keratitis.
How long does it take to recover from solar keratitis?
Most people who experience solar keratitis and solar retinopathy make a full recovery but, depending on the level of damage, this can take up to 12 months. Others never fully recover complete vision, and continue to experience vision problems such as blurriness or spots.
What to do if you think you have overdone it?

What is the damage caused by UV light?
More serious damage is known as solar retinopathy. This occurs when UV light literally burns a hole in the retinal tissues. It destroys the rods and cones of the retina and can create a small blind spot in the central vision , known as a scotoma.
Does the retina have pain receptors?
The retina does not have any pain-receptors, so you won’t feel the damage being done. It’s often not until several hours (or even days) later, when people find their eyes hurt, their vision is blurred or that dark or yellow spots are affecting their sight that they realise damage has occurred.
Do parents always warn us not to look at the sun?
Parents always warn us never to look directly at the sun. They threaten our retinas will burn up and we'll be blind forever. Is this really true or are they repeating an old urban myth? Even a quick glimpse of the sun is usually painful and difficult, so our natural instinct is to immediately squint and turn away.
