Which is most sensitive part of eye?

The most sensitive part of the eye is the retina. This retina lies below the choroid and is the only light-sensitive part. It has two types of photoreceptor cells, 1. Rod cells 2. cone cells

• Rod cells are long and contain a protein called rhodopsin.

• Cone cells are angular and contain a protein called iodopsin. The number of rod cells and cone cells in the eye is about two hundred and fifty lakh. Cone cells are useful for seeing colored objects in light and rod cells are useful for seeing in darkness.

The eyes are the most complex and sensitive part of our body. So we should take eye care and take vitamins to keep our eyes healthy.

The most important vitamin for eye health is vitamin A, also known as retinol.

Lack of vitamin A causes night blindness. This vitamin helps the eye adjust to changes in light such as light to dark or dark to light. It promotes better vision in low light, and it protects the retina against degeneration. So the role of vitamin A is more for maintaining good eyesight.

Although the eyes are our sensitive organs, we are reducing the vision of these eyes. Today, everywhere in the world we are damaging our eyes at a young age. So when we go to the doctor, he advises us to wear glasses. One of the reasons for this eye damage or reducing our vision is electronic devices mobile, computers, laptops, etc.

Turning off the lights at night, watching movies for hours on mobile, and playing games are taking away the eyesight.

Besides, those who smoke not only damage their heart but also damage the retina of the eyes. Doctors have identified smoking as the cause of poor eyesight

Due to not eating sufficient amounts of vitamins A, B, E, D, and C, the eyesight decreases. Therefore, it is necessary to keep vitamins A, B, E, D, and C in the food. Vitamins are useful not only for the eyes but also in other areas.
