Accurate optometry is key.

Optometry before wearing glasses is very key. Children's optometry should choose mydriasis optometry. Mydriasis optometry is a method of optometry designed specifically for children. It works by using drugs to completely paralyze the ciliary muscle of the eye so that it loses its regulatory role. So you can check out the child is true myopia or pseudomyopia. During optometry, you should pay attention to let the child as far as possible to relax, so as not to affect the effect of optometry. For the sake of children's health, it is recommended that parents and friends can take their children to a professional optometry place to choose glasses. In addition, do not rely solely on optometry to determine the child's glasses, but to see which degrees are more suitable.


The lifetime of contact lens

Traditional type: the replacement cycle is more than 3 months, not more than 1 year, that is, we say we abandon after one season, and we can abandon after half a year and a year.

Frequent-change type: the replacement cycle is more than 2 weeks, not more than 3 months, that is, we often say that we throw them after 1 month or two weeks.

Abandoned type: as a one-time use, common for the day use.

Contact lenses, like food, have an expiration date. For example, the shelf life of daily contact lenses is one day (after it is opened), and can not exceed this time. And the life span of a pair of glasses depends on how long you use them each day. Although different lens materials determine different wear times, we recommend that soft lenses should not be worn for more than 8 hours per day (do not wear soft contact lenses to sleep). Traditional contact lenses can be used for a long time, so the lens is easy to produce protein-lipid deposition, and then they are easy to cause eye surface inflammation and hypoxia reaction. If conditions permit, it is recommended to choose the frequent-change type and discard type, the shorter the cycle, the healthier.



Convenience and timeliness.

The essential carrier of Mobile applications is the mobile terminals. As the name suggests, these mobile terminals are not only smartphones and tablets but smart glasses, watches, clothing, accessories, and other kinds of personal belongings. They are part of what the human body wears and can be used anytime, anywhere. People can make full use of the fragmented time in life and work to accept and process all kinds of information on the Internet. They can no longer worry that they will miss any vital information, time-lapse information.


Wear glasses normally after being fitted with glasses

If you have myopia and have been diagnosed as true myopia at the same time, and the degree is above 0 degrees, you should wear suitable myopia glasses for correction. Once equipped with glasses, you should wear them except for washing your face and sleeping, because myopia patients are in a state of emmetropia after wearing suitable glasses, and the natural relationship between adjustment and convergence is restored. Wearing glasses is not only to improve eyesight, but also to read and work within an appropriate distance, so that there is a normal coordination relationship between the adjustment of the eyes and the convergence function, and to avoid eye fatigue.



Protect the lenses of your safety glasses.

Scratches can be caused by damage at work, aging, improper care, improper cleaning, or improper storage. Whatever the cause of a scratched lens can affect vision quality through the polycarbonate, causing eye strain. Make sure the safety glasses lenses are replaced in time when they are scratched.


Eye problems that may occur while driving.

Visual fatigue and xerophthalmia: when driving, the spirit and eyes are in a highly tense state, reducing the blink of an eye, which will easily cause eye fatigue and xerophthalmia. Flash glare -- car headlights and city light pollution -- can cause serious damage to the eyes. UV damage: UV radiation is strong when driving in the daytime, especially in the plateau and snow weather. Nocturnal myopia: nocturnal light is insufficient, so it can make the eye pupil dilate, causing nocturnal vision to drop influence driving safety.

Nylon: This frame material is used in some cheap eyeglasses. Nylon is strong, lightweight and flexible, and it can become brittle with age. Nylon is also a premier material for sports and performance frames, and also easily molded into today’s popular wraparound style.
