Eye sight is one of the most important part of the human body because without an eye sight one will forever live in dreams. For example, they can’t get to know what people around them look like, what their surroundings look like, and most important of all, what they would look like. Eye sight is more important than other senses in many ways.So we should not risk our this blessing by any means.
So by looking at the sun may not only give you a headache and mislead your vision temporarily, but it can also cause a very intensive damage to your retina, which is the back of eye. The effects of ultraviolent(UV) radiation on your eyes are very hazardous. As the UV exposure is connected to eye disorders such as macular degeneration, solar retinitis, and corneal problems. The most hazardous time for sun-gazing is when there is a solar eclipse. As the brightness of the sun is concealed, but the dangerous rays that burn your eyes are at their peak during the eclipse.
The sun’s UV rays can damage your eyes even when the sky is overcast. There are several categories of UV rays with differing levels of energy: Lower-energy UVA rays, which are able to get to the cornea to the lens and retina, have been connected to the development of cataracts and macular degeneration. And any UVB rays that make it through the ozone layer are absorbed by the cornea, which can lead to photokeratitis and pterygia. While UVC rays have the potential to be the most damaging but mostly they are blocked.
As when the light reaches the retina at the back of your eye, where it activates photoreceptors that relay the information to your brain. This is why you are able to see anything. But when you bombard them with too much light at a time and this can actually damage the cells and proteins that help them process light. As your retina has no pain receptors, the damage won’t cause you pain, but it will leave that blurry spot on your vision.
So the UV radiation isn’t the only issue for it but also a lot of visible light can penetrate your eye and damage the retinal tissue.So it means that the parts of your retina can no longer process light normally which is a huge loss and damage.
Hence, by seeing on the extent of the damage, recovery can take weeks, months and in some cases over a year. Normally, bodies have a self defense mechanism against staring at the sun so it provides a huge protection in this case.
