Hydration: also essential for the eyes

By Cristiano Antonino On Apr 6, 2022

It is well known that drinking is important, and that hydration in general is essential for the proper functioning of our organism

What may not be so well known is that the eye also needs to stay hydrated: the eye itself is made up of tissues, such as the cornea and vitreous, which are more than 90% water.

In the event of a reduction in the body’s fluid content, this concentration may vary.

Insufficient hydration: some causes

Under certain conditions, the eyes are under stress, which can lead to inadequate hydration.

For example, in the summer heat leads to excessive sweating, the air is made dry by the use of air conditioners or dehumidifiers, and as a result we lose fluid more easily.

Also in summer, there are more cases of retinal detachment: severe dehydration can cause contraction of the vitreous, the jelly contained at the front of the retina and behind the lens.

As it adheres to the retina, the vitreous, by contracting, is likely to exert traction that can induce retinal breaks that subsequently lead to retinal detachment.

In winter, the use of radiators, low humidity and dry wind can contribute to dehydration of the body, especially if little water is drunk.

Insufficient hydration: the most common symptoms

People suffering from insufficient eye hydration often show symptoms that may include:

– burning eyes;

– feeling of fatigue in the eyes;

– irritation typical of dry eyes;

– photophobia.

Dry eye syndrome

If there is a reduction in fluid content in the body, this concentration can vary, affecting eye health.

Insufficient hydration can lead to fluid depletion, with reduced tear production, and thus to dry eye syndrome.

Inadequate hydration? Here’s what to do

The first tip is to drink at least one and a half litres of water a day.

It is also important to always keep the environment humidified and, if necessary, lubricate the eye with tear substitutes, which can also help prevent inflammation.

Finally, the most important thing is to consult an ophthalmologist, who can prescribe the best treatment, once the correct diagnosis has been made.
