Eye fatigue is a condition where the eyes are constantly tired and in some amount of pain as well. The other symptoms of this condition can also include swelling, burning and itching. Other ailments and conditions in the body like computer vision syndrome and others can cause this condition as a side effect and it should be referred to an ophthalmologist at the earliest for treatment. So what else do we know about tired eyes or eye fatigue? Here are our list!

Causes: Usually, this condition may be caused by activities that require the constant movement and focus of the eyes for tasks like reading, writing, focusing on the glare and flicker found in computer screens or on smartphones, and more. Also, driving for a long time and exposing the eyes to too much sunlight can lead to this condition. Video games and handheld devices may also lead to the same. Also, the presence of more serious ailments in the body as well as computer vision syndrome that hits roughly 50 to 60% of workers who use computer screens on a daily basis and for long hours, can lead to this condition. Lack of sleep and a poor diet that does not have plenty of nutrients can also cause this condition and other related symptoms.

Symptoms: There are many symptoms of this condition including redness, itching, burning, swelling, watery eyes and much more, which will leave the eyes feeling tired. Also, blurred or cloudy vision may be experienced by patients for whom this condition has become more severe. The patient will also end up facing difficulty when it comes to focusing or driving for long periods of time, and headaches may take over after a few hours of reading or computer screen times. Also, related symptoms include acute pain and dull aches in the neck and shoulders which can trickle down to the upper back region.

Treatment: The best treatment for this condition is with the help of lifestyle changes like cutting down your working hours and taking frequent breaks. Also, you could place your computer screen at least 20 to 26 inches away from your face while you are working so that your eyes are at a more comfortable distance and do not get affected too easily. You must also try and limit your screen time in terms of hand held device usage. A doctor may also carry out an eye exam and prescribe artificial tear inducers or bifocal lenses to deal with the problem.

Persistent eye fatigue must be checked by an ophthalmologist who will arrive at a proper diagnosis and treatment.

Redness, itchiness and watery eyes are common symptoms of eye allergies. Pollen, mold, dust and pet dander are common allergens that trigger such allergies. Other triggers include adverse reactions to cosmetics and eye medication such as eye drops. Being allergic to certain food items rarely causes eye conditions such as itchiness or excessive tearing. When the surface of the eye is exposed to allergens, it releases histamines. This causes itchiness and makes the eye red and watery.

However, sometimes these can also be symptoms of a larger problem. Itchiness in the eyes and excessive tearing can also be a symptom of conjunctivitis or caused by eye disorders like dry eyes and blepharitis. Ironically,dry eyes is the most notorious factor amongst the above. Watery eyes could also be caused by clogged tear ducts or eyelids that turn inwards or outwards.

If your eye feels itchy or is persistently watery, you must consult an eye doctor. To correctly diagnose the condition and recognize the symptoms triggering it, he will conduct a thorough eye exam and discuss your medical history and lifestyle. If the condition is triggered by an allergy you might also require blood tests for allergies. This will decide your course of treatment. A few tips that could help are:

Avoid allergens
The best way to keep your eyes healthy is to limit their exposure to factors that could irritate it. Avoid going outdoors during the pollen season especially if it is windy. Wearing wraparound sunglasses can also help create a barrier between your eyes and the allergens. Within the house, ensure that your air filters in the air conditioner are cleaned regularly.

Avoid contacts
Switch to spectacles or consider lasik surgery if you wear contacts regularly and often suffer from eye allergies. Alternatively you could switch to daily disposable lenses to avoid the buildup of airborne allergens on the surface of the lenses.

Eye drops
Non prescriptions eye drops that help lubricate the eyes are easily available over the counter and can help relieve itchiness. This can also keep your eyes from drying out and thus prevent watery eyes.

Antihistamines
The histamines released by the body on contact with an allergen dilute blood vessels and make then abnormally permeable. Antihistamines reduce these reactions by not allowing the histamines to attach themselves to cells in the body. Antihistamines can take a while to react and can make you feel drowsy. Hence it is advisable not to take them when operating heavy machinery or driving.
