Question

Why we never look directly at sun ?​

Answer 1

Explanation:

Looking steadily at the sun for any prolonged period can cause damage to the retina. This is the collection of light-sensitive cells located at the back of the eye which transmit images to your brain. This kind of damage to the retina is known as solar retinopathy.Exposing your eyes to the sun without proper eye protection during a solar eclipse can cause “eclipse blindness” or retinal burns, also known as solar retinopathy. This exposure to the light can cause damage or even destroy cells in the retina (the back of the eye) that transmit what you see to the brain.

Answer 2

Answer:

Beware … 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.
