Visual fatigue is a group of symptoms that make the human eye look at objects more than its visual function can bear due to various causes, resulting in visual impairment, eye discomfort or systemic symptoms after using the eyes。
Epidemiological studies showed that 23% of school-age children, 64% ~ 90% of computer users and 71.3% of dry eye patients had different degrees of visual fatigue symptoms.
So how should visual fatigue be alleviated or prevented？
1. Balanced diet
Dietary factors are important regulatory factors related to the incidence of visual fatigue. Appropriate dietary supplement of relevant nutrients can prevent and delay the occurrence and development of visual fatigue. Young people like to eat snacks, drinks and fast food. This kind of food has low nutritional value, but it has large calories. The intake of these foods should be controlled. Eat less takeout, cook more and eat a balanced diet。
2. Use eye drops with caution
Different eye drops have their own uses, such as treating eye infections, reducing intraocular pressure, relieving inflammation and pain, or relieving dry eyes. Like other drugs, many eye drops have some degree of side effects.Frequent use of eye drops will not only cause drug dependence, reduce the self-cleaning function of the eyes, but also cause damage to the cornea and conjunctiva. Eye drops containing antibacterial ingredients may also make bacteria in the eyes resistant to drugs. Once an eye infection occurs, it is not easy to treat it.
3. Reasonable allocation of working hours
Studies have shown that regular intervals can restore the eye's regulatory system.Following the 20-20-20 rule requires a 20 second break from the screen every 20 minutes. According to the optometry times, California optometrist Jeffrey Anshel designed a 20-20-20 rule to facilitate rest and prevent eye fatigue. That is, take a break every 20 minutes of using the computer and look at the scenery (preferably green) 20 feet (about 6m) away for at least 20 seconds.
4. Wear anti-fatigue lenses
Universe Optical anti-fatigue lens adopts asymmetric design, which can optimize the binocular vision fusion function, so that it can have high-definition and wide field of vision when looking close and far. The use of near use auxiliary adjustment function can effectively reduce the symptoms of eye dryness and headache caused by visual fatigue. In addition, three different kinds of lower light of 0.50, 0.75 and 1.00 are designed for all kinds of people to choose, which can effectively reduce the visual fatigue caused by long-time eye use and meet all kinds of close workers, such as students, white-collar workers, painters and writers.
Universe optical fatigue relief lens has short adaptation time for both eyes. It is especially suitable for beginners. It is a functional lens available to everyone. It can also be added with special designs such as impact resistance and blue light resistance to solve the trouble of visual fatigue.
