Disidratazione, bere poca acqua affatica anche gli occhi

Dehydration causes eye fatigue

Paying close attention to one’s eyesight means taking good care of eyeball health

MILAN – If you want to keep your eyes healthy and full of vitality, it is essential to drink a lot of water. It has emerged that dehydration can have a negative impact on all the body’s organs (especially the kidneys). However, it is perhaps not widely known that it can also cause problems for the eyes and as a result, for one’s vision.

What does water loss involve?

The body loses fluids in various ways during the day: through sweating, urination or when you have colon problems. Furthermore, if you stay out in the sun for too long, if you vomit, if you are diabetic, or if you consume alcohol, the risk of dehydration increases. When the body starts to lose too many fluids, many symptoms appear, ranging from thirst to reduced urination.  But there is also reduced production of tears due to poor lubrication. This condition, therefore, increases dryness in the eyes and the likelihood of vision problems.

The importance of tears

Tears are necessary for keeping the eyes lubricated and enabling clear vision. They help wash away the debris which enters the eyes, such as dust and reduce the risk of developing eye infections. Poor hydration of the eyes also gives rise to irritation and this can then cause blurred vision. Eye drops can be used to lubricate the eyes and reduce the symptoms of dryness, as well as being used to cleanse the eyes, but the best way to alleviate dryness in the eyes is to drink enough water every day.

Caring about your diet

A healthy diet can also be good for the eyes. For adults aged between 18 and 60, The American Optometric Association recommend the consumption of substantial amounts of cabbage, spinach, carrots, peppers and sweet potatoes, because they contain nutrients which are useful for the eyeballs. Incorporating such foods in one’s daily diet can help protect against eye diseases such as glaucoma, cataracts and macular degeneration, prevent dry eye syndrome and maintain good eyesight.
