Advancing age: Tear production tends to diminish with age. Dry eyes are more common in people over 50[i].
Gender: Women are more likely to experience dry eyes due to hormonal changes such as those occurring during pregnancy, menopause and through the use of hormonal contraceptives[ii].
There are certain medical conditions or nutrient depletions which result in dry eyes:
Allergic eye disease
Meibomian gland dysfunction
Vitamin A deficiency
To support healthy membranes:
Beta Carotene Complex / Bilberry, Lutein & Astaxanthin Complex – Bilberry, Lutein & Astaxanthin Complex – Carotenoids are a type of vitamin A known to support eye health. Lutein and astaxanthin are carotenoids which support many aspects of eye health, helping to prevent dry eyes[vi] [vii]. Bilberry may also provide relief from dry eyes [viii].
Use a humidifier if your environment is very dry.
Ensure you take breaks during long tasks - Close your eyes for a few minutes to replenish moisture in the eyes.
Position your computer screen below eye level - it may help slow the evaporation of your tears.
Stop smoking, smoking has been linked to an increased risk of dry eyes[xi].
