What should you do if your eyes are tired?😵😵😵

During the 24 hours a day, our eyes are in use at other times except for sleeping time. If you look at mobile phones, computers, TVs or books for a long time, I believe you will see things blurred sometimes. For example, the handwriting is blurred and confusing when reading or the wrong line is read when reading. In fact, this is some manifestations of asthenopia. In addition, if long-term asthenopia is not effectively alleviated, it can lead to a decline in visual function.

Causes of asthenopia.

Asthenopia is very common in clinical practice. It is caused by the sudden relaxation or convulsive contraction of the temporary ciliary muscle. There are many factors that cause asthenopia:

1. Use your eyes for too long.
2. The effect of object color.
3. Nervous.
4. Sleep disorder.
5. The effect of light.
6. Excessive smoking and drinking.
7. It is related to physical fitness.

Methods to prevent asthenopia.

1. In daily life, we can do more eye exercises.
2. Eyes should be used wisely to avoid using eyes for too long.
3. Exercise to enhance physical fitness. 
4. Avoid staying up late to ensure adequate sleep time.
5. Participate in outdoor activities. Let your eyes see the distance and green plants more.
6. Eliminate the unfavorable factors in the work and study environment, so that the eyes are in a comfortable eye environment.

Drugs to relieve asthenopia.

In addition to improving daily eye habits, we may also need to use drugs at certain times. However, there are many kinds of eye drops on the market and not every one is suitable for us. If we choose the wrong one, it will cause irreversible damage to our eyes.

1. Artificial tears

Artificial tears are currently the safest medicine to relieve eyesight fatigue. It mainly simulates natural tears, which can form a protective film of tears on the surface of the eyes and reduce the loss of water in the eyes. When the eyes are dry, artificial tears can appropriately relieve the symptoms and do not contain any anti-allergic or anti-inflammatory ingredients. In addition, some artificial tear products contain antiseptic ingredients. Long-term use of artificial tears containing antiseptic ingredients will cause damage to the eyes.

Commonly used drugs are: sodium hyaluronate eye drops, polyethylene glycol eye drops, sodium carboxymethyl cellulose eye drops, hydroxysugar eye drops and so on.

The main component of sodium hyaluronate eye drops is sodium hyaluronate, which imitates the normal components of human tears. It can moisten the cornea and promote the healing of corneal wounds. It is mainly used for the treatment of dry eye and alleviating symptoms of eye dryness. Therefore, if there are symptoms such as dryness, soreness and foreign body sensation in the eyes, and it is clear that it is dry eye after examination, you can choose sodium hyaluronate eye drops to relieve the symptoms. However, although artificial tears are safe, they cannot be abused. Generally, it should be controlled 3-4 times a day. Some patients with severe dry eye can increase the number of medications depending on the situation. Under normal circumstances, no more than 6 times a day is appropriate.

2. Chondroitin sulfate eye drops

There are many different products on the market for chondroitin sulfate eye drops. For example, chondroitin sulfate + taurine, chondroitin sulfate + taurine, chondroitin sulfate + vitamin E + vitamin B6 + allantoin + taurine, etc., can all improve the symptoms of eye fatigue and dry eye.

Chondroitin sulfate is an acidic mucopolysaccharide, which is one of the important components in eye tissue. It has the functions of improving microcirculation, regulating cell growth, protecting the cornea and promoting the repair of corneal tissue damage. At the same time, it can also promote corneal water metabolism, form a protective film on the surface of the cornea, prevent water from dissipating, effectively relieve eye fatigue and dry eye symptoms. 

Taurine is an amino acid antibacterial and anti-inflammatory drug. In addition to its antibacterial and anti-inflammatory effects, it also participates in a variety of physiological activities in the eye tissues, promotes metabolism and improves asthenopia symptoms.

👉In addition, we can eat foods rich in lutein such as carrots, cabbage, corn, spinach, and kiwi. Lutein is an antioxidant. It is the main pigment that constitutes the macular area of the retina of the human eye. If it is lacking, vision will decrease and the eyes are easily dim. Therefore, it is very important to properly supplement foods containing lutein.
