looking to the sun

The Bible states :The cause when you looked at the sun:

Job 31:26
If I have looked at the sun when it shone Or the moon going in splendor,

◼Photokeratitis and photoconjunctivitis:

Both feel like a sunburn to the eye and are caused by UVB rays. They can be caused by directly looking at the sun, or by reflected UV from snow, concrete, water and sand, or from arc welding. Snow blindness is a form of photokeratitis. Welder’s flash or ‘arc eye’ is another form.

You may already know that it’s pretty difficult to look directly up at the sun at noon. It’s not only immediately discomforting, but can also have long-term or permanent adverse effects on your eyes. In fact, that’s why scientists and stargazers strongly advise you to avoid watching a sun.

Basically, harmful ultraviolet rays from the sun can damage your eyes if you look at the sun directly. But what about the times when you look at the sun, but with your peripheral vision, or in other words, from the corners of your eyes? We don’t usually hear about people getting eye problems by looking at the sun sideways, right? Why is that?

Why does having the sun visible in your peripheral vision not do any damage to your vision?

How are eyes affected when you look at the sun directly?

When one stares at the sun for too long, it can result in too much ultraviolet light flooding the retina, causing solar retinopathy. In the worst cases, this can cause permanent blindness (although that’s rare), but looking directly at the sun is so painful that it’s usually impossible for anyone to stare at the sun for that long. Typical damage to the eyes after staring directly at the sun include dark or yellow spots, dimmed or blurred vision, and loss of vision in the center of the eye (the fovea), among others.

Looking up at the noon sun is one of the most dangerous things you can do to your eyes.

Now, let’s try to understand the specifics of this issue – there is a lens in the front of the eye, whose primary job is to focus incoming light onto the macula – an oval-shaped pigmented area near the center of the retina. It has the highest concentration of nerves and the thinnest protective layers.

The pupil is directly in front of the eye; so, when you look at the sun directly, the lens focuses the light right on the retina, which can result in damage.
