Why does visual performance vary so much from person to person?

Color perception, three-dimensional vision and night vision vary greatly between people, but what causes these discrepancies in visual performance between individuals?

Part of the population faces visual difficulties, however, through the use of glasses and contact lenses, an effective correction of variations in visual performance is observed.

However, as time goes by, the differences between people tend to increase. It is certainly not possible to say that at 80 years old we see the same way as we did at 20 years old. Visual acuity, night vision, spatial perception and color perception all deteriorate over time.

Around the age of 40 or 50, the lens and ciliary muscle lose elasticity, which consequently makes it difficult to focus at different distances. As a result, many people begin to feel the need to move objects, such as books or screens, away from their eyes in order to see more clearly.

On the other hand, night vision depends on the proper functioning of the rods in our retina. In some cases, vitamin A deficiency can reduce night vision, but this can be easily restored.

Differences in vision can also be caused by pathological diseases that arise throughout life.

How can I harness the potential of my vision?

By using glasses or contact lenses!

Without a suitable pair of glasses or lenses, the wearer's vision potential cannot be fully utilized, and the most subtle details are not considered.

To do this, it is essential that you carry out a visual examination regularly!
