→ Eye dehydration can occur for many reasons, including chronic and temporary 
It may happen when your eyes cannot produce enough tears to weave them.

→ The liquid of tears consists of water, lipids, proteins and electrolytes. Tears keep the surface clean and smooth and help shield the eye from pollution.

Any one of the three primary tear compounds may have been faulty:

➜Outer fatty layer

Produced in the edges of the meibomian glands, which contain lipids. It helps the tear fluid to slide and reduces the evaporation rate of its more fluid middle class. The lack of production of this layer leads to more evaporation of the middle layer, resulting in dry eyes. The blockage that produced that layer was more common in people suffering from blepharitis and various skin diseases.

➜Middle liquid layer

The central compound in this layer is water, a little salt. It is produced in the lacrimal gland. This layer cleans the eyes of the molecules that enter it. If the layer is deficient, the outer fatty layer mixes with the inner mucus and produces a yarn mucus.

➜Inner mucus layer

This layer helps to spread tears properly and uniformly across the surface of the eye.

⏩ Causes of eye dryness:

  • Dehydration can occur as a result of an imbalance between different tear compounds, or as a result of the lack of tear fluid. This could be insufficiency due to eyelid problems.
  • People over 50 years old.
  • In women in the menopause generation.
  • People who had laser surgery for eye.
  • People with disturbed tear glands.
  • Patients with various group diseases, such as diabetes, rheumatoid arthritis, gout, lupus, and scleroderma.
  • Use of many medicines, including diuretics used to reduce blood pressure, antihistamines for allergy, birth control pills, antidepressants and painkillers
  • Multiple environmental factors such as wind, altitude and dry air.
  • Work requiring continuous focus.
  • Deficiencies in some nutrients, especially vitamin A and omega 3, maybe a cause of eye dryness.

⏩ Eye dehydration complications:

If eye dryness is severe and not treated for a long time, there may be scars (Cicatrices) on the surface of the cornea, which may cause disorientation.

⏩ Preventing and treating dry eye:

• Eye protection against direct stimulants such as wind, dehydration, and various chemicals. With glasses or swimming goggles.

• Intervals during activities that require the continuous focus of attention.

• Placing the computer monitor at a location lower than the eye level, to avoid significant eyelids opening.

• Quit smoking or avoid smoking.

• Use Moisturized eye drops: 

Dehydrated eyes should have heard of special eye drops that contribute to wetting. These drops must be used regularly and placed every few hours

• Eat omega-3 foods.

It seems that eye health has also been affected by the numerous benefits of omega-3! Because omega-3 or fish-oil cereals, as they are known, help reduce and control inflammation in the body, particularly eye infections and eye inflammation, can be a major cause of drought, make sure to consume omega-3 either from its natural sources of fish, nuts, vegetable oils, or by ingesting their dietary supplements.

• Take a break from the contact lenses.

Wearing contact lenses may be one of the main reasons for dry eyes, so if you do not need to wear them for certain cosmetic purposes, we advise you to avoid them.
If you need to wear lenses all day or at work, as soon as you get home, remove them and take a rest.

• Make sure from the environment you live in.

Sometimes living in dry places can make the eyes dry. Especially in winter where heating systems are frequently used, which in turn may dry up the workplace or home environment and thus increase the dehydration of the eye.

• Make sure your medication doesn't cause dehydration.

Certain types of medication can cause eye dehydration, such as certain types of oral contraceptives and menstrual regulation or antihistamines used to treat allergies, since they are designed to dry out the sinuses, and thus may increase the risk of eye dry as well. In this case, we advise you to consult a doctor about the best species and alternatives that may be less dried.

• Learn Eye massage.

There are simple movements of eye massage that may help to relieve them and reduce dehydration:

  • Rub your hands to heat them, and then put your hands full over your eyes with elbows on the table. Take a deep breath and try to move your palms with a firm upper hand with slight eye pressure.
  • Use the thumb to massage the eyebrow area starting between the eyebrows, close your eyes, move to each eye and rub them gently with slight pressure, open your eyes and take a deep breath.
Such occasional movements help to relieve the eyes.
