Teenagers whose prescription changes particularly quickly are best to change their glasses once every six months to a year.

Glasses are generally required to be done twice a year in children with developing glasses.

Widening, growing the face shape, and constantly changing the frame of the glasses, so as to ensure that the lens power is suitable for the child's refractive state.

As the child grows, his interpupillary distance will widen, the power of the eyes will deepen, and wearing ill-fitting glasses will not only accelerate myopia.

progression, but also visual fatigue. Some metal frames are easy to be corroded by sweat and discolored, and long-term wear is easy to cause ** disease.

Lenses are not well maintained and prone to wear and tear, so it is not recommended to wear lenses that are not clear.

Precautions for changing glasses

If you have worn glasses in the past, you need to provide the doctor with the original prescription of glasses, and make appropriate adjustments according to the prescription before and after. After the glasses, you also need to choose the wearing time according to your own situation, those with low prescription can wear it at work and study, and those with higher prescription can increase the wearing time accordingly.

Before fitting glasses, it is recommended to complete refraction, prescription detection and other examinations to clarify the type of refractive error and the specific prescription. When dispensing glasses, strictly according to your own prescription, under the guidance of professionals, choose the appropriate prescription glasses, which can effectively correct vision and avoid excessive growth of prescription. The prescription of glasses should be avoided from over-wearing, which can lead to faster deepening of the prescription.

For children and adolescents in the developing period, it is recommended that they need to have an optometry once a year or so, and decide whether to change the glasses according to the results of the refraction. For adults who have basically not progressed after the age of 18, they should change their glasses according to the wear and tear of the glasses, and of course, it is also recommended to have an optometry every time they change their glasses.

Vision will change over time, and according to the previous prescription glasses, it is likely to do not match your real vision, which is not conducive to vision control correction. There is also a situation that the mirror surface of the glasses is prone to scratches after a long time, which is easy to affect the refractive correction performance, so we do not support wearing the same pair of eye wax glasses for too long.

There are also some friends who think that the glasses are more expensive, so they don't need to be replaced regularly. But the value of glasses is closely related to eye health, and many people simply can't do without it. Of all the accessories, glasses are also used the most frequently.
