Dry eyes are caused by inability of your tears to provide proper eye lubrication. The composition of tears (watter, fat, mucus) enables the protection of of your eyes. The cause for this can be either reduced tear production or increased desiccation.
Inability to produce enough tears is called keratoconjuctivits sicca. Among some people, the problem lies in disproportion of tear composition. Medical causes for this condition include: age, diabetes, rheumatoid arthritis, Sjögren’s syndrome, scleroderma, lupus, thyroid illnesses, vitamin A deficiency, clogged eyelid glands, blepharitis, rosacea, allergic reactions, tear gland damage.
Medications such as: hormonal therapy, antihistamines, decongestants, antidepressants, antihypertensives, drugs for acne, Parkinson’s etc , are known to cause the condition. Causes of increased tear include: air composition, wind, less blinking( while driving or looking at the screen), smoke, eyelid disorders ( entropion, ecropion).
4 Making a Diagnosis
Dry eyes condition is diagnosed by performing several tests.
Once you decide to visit your family doctor, do not forget to mention all the symptoms which you are experiencing, recent life changes, other chronic illnesses and medications that you are taking.
Your doctor may refer you to the ophthalmologist. Try with using special eyedrops ( artificial tears) for eye dryness. Eyedrops that reduce eye redness can cause additional eye irritation.
Doctor are likely to undertake some tests. These include comprehensive eye examination and measuring your tear production using the Shimmer test. The main idea behind this test is measuring the distance of paper soaked by your tears after previously placing them beneath your eyelids.
Other tests are used to determine the quality of your tears, such as fluorescein clearance test.
