The sun is the life source of our planet. By providing heat and light main reason for living Our star will continue to rise and set in our sky for billions of years.

One of the things most of us have heard about the sun is that if you look at it for a long time, to permanent blindness even cause. So how come it can cause such damage to our eyes?

First of all, it is necessary to know that light actually contains an extremely high amount of energy.

However, the power and distance of the light sources weaken the effect of the light until it reaches our eyes. Therefore, while it’s okay to look at some light sources, whether in the sky or on Earth, some can cause problems.

While looking at the sun with a telescope, to prevent damage special filters are used. Looking through a telescope without these filters is one of the worst ideas imaginable. Even if you normally raise your head and stare for a long time, without just needing a telescope, you can ruin your eyes.

In clear weather, the sun is 5000 times brighter than an average light bulb. If you look at the sun with that much force and turn your head for a moment, you will see a blurry round shape appear before your eyes.

The reason for the formation of this image is that your cells in your eye that process the information about the incoming light and the proteins used during these processes process as a result of intense light bombardment. by short circuit caused by damage.

Because there are no pain receptors in the eye, none you feel no pain or pain; but the blurry image stays in front of your eyes for a while.

If you stare too long, you’re doing more than just straining your eyes.

First of all, an abnormally high amount of ultraviolet rays it burns your cornea; And this event causes you to feel very sharp pain.

Because in the cornea, unlike the rest of the eye there are pain receptors; This is exactly how you feel pain when you get something in your eye.

Moreover, ultraviolet rays are not the only problem; intense amount of lightdamage the tissues in your retina and it stops your eyes from processing light normally.

As the exposure time increases, the recovery time from the damage you have sustained becomes longer and can sometimes take years. In very rare cases your eye will never heal.

Another problem is the misconception that it is safe to look at the sun during eclipses, since most of the star’s light is blocked.

Under normal circumstances, our eyes squint when we look at the sun, this is a precaution our body automatically takes. However, during solar eclipses, since the sunlight is very low, these mechanisms in our body do not play a role and we can look at the sun for a long time. Meanwhile, it keeps getting corrupted without realizing it and to permanent blindness we can come up with results.

In short, there is nothing good about looking at the sun. Instead at night to the moon You can long look or explore other stars you can see as much as you want.
