It is difficult to accurately determine how many people have gone blind from the sun, as there is limited data regarding this phenomenon. That being said, the American Association of Retinal Specialists reports that solar retinopathy is a rare, though serious, condition that can lead to permanent vision loss.
This occurs when the ultra-violet rays from the sun damage the macula, the part of the eye responsible for central vision. This is usually a result of directly looking at the sun, and is sometimes made worse by optical aids such as binoculars or telescopes.
As most cases of solar retinopathy have taken place in patients who have experienced a transient increase in eye sensitivity to light, it is difficult to determine the exact number of people who have gone blind from the sun.

Has anyone gone blind looking at the sun?
Yes, there have been cases of people going blind from looking at the sun. This condition is known as solar retinopathy and can occur if you look directly at the sun for a long enough period. Solar retinopathy is a damage to the retina of the eye caused by prolonged exposure to intense visible, infrared, and ultraviolet radiation emitted by the sun.
It can permanently damage the eyes and even lead to total and irreversible blindness. The condition often goes away within a few days, but in some cases, some persons may experience permanent visual impairment or even blindness.
To prevent solar retinopathy, it is important to always wear protective eye wear when viewing the sun, even during a solar eclipse. Additionally, you should never look directly at the sun for any period of time, even if you are wearing protective eye wear.
How long can you look at the sun before you go blind?
According to the Royal National Institute of Blind People, you should never look directly at the sun, even during an eclipse or when the sun is low in the sky. Looking directly at the sun can result in serious and permanent damage to your eyes.
Even brief periods of exposure to direct sunlight can cause solar retinopathy, a condition which results in impaired or loss of vision. Solar retinopathy can occur after just a few seconds of exposure and is usually worse the longer you look at the sun.
It can take multiple days of exposure to cause permanent vision damage, so it is recommended that you never stare at the sun for an extended period of time. Wearing properly certified sunglasses can protect your eyes from the sun’s harmful rays and should be used if you want to take a quick glance at the sun.
Who went blind from staring at the sun?
Nobody is known to have gone blind from staring at the sun, however staring at the sun can cause serious injury to the eyes. Prolonged exposure to the sun’s ultraviolet (UV) rays can cause a condition known as solar or photochemical keratoconjunctivitis, sometimes called “sunburn of the eyes”.
Symptoms of this condition include redness, pain, swelling, blurred vision, and sensitivity to light. In extreme cases, this condition can permanently damage the eyes, resulting in blindness or decreased vision.
Some of the risk factors include those with pre-existing vision problems, people who are taking certain medications or have certain medical conditions, and children or teenagers who spend long periods of time outdoors.
It is important to protect the eyes when exposed to sunlight by wearing sunglasses or other protective eyewear.
Do blind peoples eyes hurt when they look at the sun?
No, blind people’s eyes do not hurt when they look at the sun. Since they are blind, their eyes will not sense the light, so they will not be affected by it. However, people who have some sight may be at risk of burn to the eyes if they look directly at the sun.
Exposure to bright sunlight can cause sunburn to the eyes, also known as photokeratitis. It is important for everyone, regardless of their level of vision, to protect their eyes from sun damage – this includes wearing sunglasses, avoiding looking directly at the sun and limiting the amount of time spent in the sun.
What happens if you look at the sun for 20 seconds?
When you look directly at the sun, even for a short amount of time, you run the risk of damaging your eyes. The sun emits ultraviolet (UV) light, which can burn the back of your eye, even if it doesn’t appear to cause any immediate pain.
UV radiation is one of the most common causes of preventable blindness around the world. If you look at the sun for 20 seconds, you are exposing your eyes to a very large dose of UV radiation which has the potential to cause serious damage, such as vision loss, inflammation of the cornea, or even permanent blindness.
It is possible for damage to occur even after just a few seconds of looking at the sun, so it is important to protect your eyes when looking at the sun. Wearing ultraviolet-blocking sunglasses or using an approved solar filter over the eyes are two ways to avoid any potential damage.
Can you go blind from looking at the sun for a second?
No, you cannot go blind from looking at the sun for only a second. However, staring at the sun for a prolonged period of time can cause permanent damage to the retina, which can eventually lead to impaired vision or even blindness.
When looking at the sun directly, you can cause serious damage to the photosensitive cells in your eyes, which can lead to a condition called solar retinopathy or photic maculopathy. This can cause blurred vision or distortion in the central vision, blind spots, or other vision issues.
The worse the vision damage, the longer the stare at the sun was. To protect your vision and prevent any damage, experts highly recommend not to ever look directly at the sun with any of your unprotected eyes.
What percentage of Earth’s population is blind?
Based on a 2015 estimate by the World Health Organization, approximately 1. 3 billion people, or just under 19% of the world’s population, suffers from some form of vision impairment. Of those, around 36 million people (which equates to about 0.
5% of the world’s population) are blind. This means that very roughly speaking, 0. 5% of the world’s population is blind.
Impairment in vision is based on a variety of factors, including lifelong disorders or physical accidents that cause deprivation of vision. Diabetes, macular degeneration, glaucoma, cataracts and uncorrected refractive errors such as nearsightedness and farsightedness are leading causes of impaired vision worldwide.
There are also diseases like trachoma and onchocerciasis, major concerns in developing countries, which can cause devastating and irreversible blindness if left untreated.
Despite the fact that millions of people struggle with vision impairment, it’s been estimated that about 75% of vision impairment cases can be prevented, cured or even made less debilitating through available and affordable eye care treatments.
This means that there are actions than can and should be taken to reduce the amount of vision impairment that inhibits the quality of life of so many people worldwide.
Can I see again if I go blind?
Unfortunately, if you become blind, no matter what the cause may be, you will not be able to see again. The eyes are very complex structures and currently, there is no medical procedure that can restore your sight once you have lost it.
However, there are many adaptive strategies and devices that can help people with vision loss adjust to the challenges of day to day life. This includes various low-vision aids, assistive technology, and services that can help you make the most of your remaining vision.
Additionally, there are rehabilitation programs designed to teach individuals with vision loss how to learn skills needed for independent living. There are also support groups for people with vision loss or their caregivers to share advice, learn about resources, and make connections with others in the same situations.
Is sun blindness permanent?
No, sun blindness is not permanent. It is a condition known as photokeratitis, which is a temporary inflammation of the eye’s cornea due to overexposure to UV rays. It is also referred to as ‘snow blindness’ or ‘welder’s flash’.
It typically resolves itself within 48-72 hours, however, if symptoms don’t improve, it is recommended to seek medical attention. It can generally be treated with the use of artificial tears, cold compresses and more serious treatments such as steroid drops or ophthalmic ointments, depending on the severity of the symptoms.
As for prevention of sun blindness, it is best to wear sunglasses that block UV rays and to avoid looking directly at the sun.
Can blind people dream?
Yes, people who are blind can dream. Blindness does not stop a person from experiencing dream imagery. While the dreams of a visually impaired person may not include visual details, all other senses are still active in their dreams, so they can experience thoughts, emotions and sensations.
In fact, many visually impaired people associate dreams more closely with tactile, olfactory and auditory elements than with visual experiences. Like sighted people, blind people dream in both color and black-and-white.
Can a sunset blind you?
No, a sunset cannot blind you, as the intensity of the light is not typically bright enough or focused to cause eye damage. In fact, looking at a regular sunset (as opposed to staring at the Sun directly) is generally considered healthy and even beneficial.
Sunsets can provide a calming, therapeutic effect, with the warm colors and gradual decrease in sunlight providing comfort and invigoration. Although it is not possible to be blinded by looking at a sunset, it is important to be mindful of not looking directly at the setting Sun, as the Sun emits powerful UV rays and light which can cause problems with your eyesight if looked at for extended periods of time.
It is generally recommended to avoid direct exposure to the Sun for prolonged periods.
Will I go blind if I accidentally looked at the sun?
No, you will not go blind if you accidentally looked at the sun. While it is not recommended to look directly at the sun with your eyes unprotected, because it can cause serious and permanent damage to your eyes, looking directly at the sun for a very short amount of time is unlikely to cause any permanent damage.
That said, it’s still important to take preventative measures to protect your eyes when looking at the sun. You should be sure to look away from the sun and use special equipment, like eclipse glasses, to shield your eyes from the dangerous UV radiation that the sun emits.
Also, avoid looking directly at the sun even for short periods of time on a regular basis. Over time, repeated exposure to the sun can damage your eyes, potentially leading to vision loss.
Are we blind for 40 minutes a day?
No, we are not blind for 40 minutes a day. While it is true that blind people are missing certain visual inputs, the general population is not blinded for any set amount of time. In fact, it is impossible to determine how long an individual is without sight without doing medical tests, which would be unlikely to be done on a daily basis.
Additionally, even people with significant visual impairments usually have some ability to detect light, and this ability can vary depending on an individual’s eyesight and the type of visual impairment.
Therefore, it is highly unlikely that all people are blind for 40 minutes a day.
Who was the first person to look at the sun and go blind?
The ancient Greek legend of Eupraxis tells the story of the first person to look at the sun and go blind. According to the legend, Eupraxis was an apprentice to a blacksmith. He stole some of his master’s tools and went to a nearby mountain to make his fortune by forging gold.
Unfortunately for Eupraxis, the mountain he chose to work on happened to be Mount Helios, the resting place of the sun god Helios.
As Eupraxis began to hammer his tools, he became lost in the moment, and he unintentionally gazed directly into the sun. In the blink of an eye, Eupraxis was irreversibly blinded by the powerful rays of the sun, and he was unable to see any light for the rest of his days.
Eupraxis’s story is often told as a cautionary tale about the dangers of looking directly into the sun. Though it’s unlikely that anyone in the ancient world would have actually been able to do so, the tale of Eupraxis has served as a powerful reminder to take precautions when observing the sun.
