Viewing direct, unfiltered sunlight (even for an instant) causes permanent, irreversible eye damage including blindness.

Accordingly, What is it difficult to look at the sun directly?
damage will occur! 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. … It destroys the rods and cones of the retina and can create a small blind spot in the central vision, known as a scotoma.

Why is looking at the Sun bad?
Solar Retinopathy: The most common instance of solar retinopathy is direct eclipse viewing or sun gazing without adequate eye protection. UV rays enter the eye, going through the pupil to the retina at the back of the eye, damaging the rods and cones of the retina creating a blind spot.
Do blind people see black?

Can you look at the sun through a camera?
It’s important to note that you should never look at the sun through an unfiltered camera, telescope or binoculars, regardless of whether you’re wearing eclipse glasses.
