How often should spectacle lenses actually be replaced?

Presumably, most people will keep using the same pair of glasses until they can no longer be used as long as the lenses are still clear and the frames are not broken and can still be worn.

In fact, lenses are consumables with a certain service life and need to be replaced when that time comes. If they are used beyond their intended lifespan, not only will the lenses be in a bad state, but it will also cause harm to the eyes.

Under normal circumstances, adults can replace their glasses every 2 to 3 years.

However, strictly speaking, the frequency of changing glasses also varies from person to person. For example, different people have different myopia or hyperopia conditions and are in different age groups. Now let's talk about how often people in different groups need to change their glasses.

It is recommended that children and adolescents change their glasses every six months to one year.

Children and adolescents are in a period of rapid growth and development. Their eye conditions change very quickly. Moreover, many of them are at school age, facing great pressure from schoolwork, using their eyes at close range for long periods, and also liking to play electronic products while having less time for outdoor activities.

All these factors combined lead to a rapid increase in the degree of myopia among adolescents, so it is necessary to update and wear suitable glasses for correction in a timely manner. Therefore, it is recommended that children and adolescents change their glasses every six months to one year.

Of course, whether glasses need to be changed specifically depends on the optometry results. You should choose whether to change the glasses under the advice of a professional optometrist.

*Even if you don't change your glasses, you should also have regular optometry examinations, at least once every 3 to 6 months, to keep abreast of your eye conditions in a timely manner.

It is recommended that adults change their glasses every 2 to 3 years.

Generally speaking, the myopia condition of adults is basically stable, and glasses don't need to be replaced too frequently. However, due to busy work, long hours of staring at electronic products, staying up late to watch dramas, play games or engage in other entertainment activities, the vision of some adults may also fluctuate.

Moreover, over time, the coating of the lenses may be seriously damaged, the clarity may decline, and problems such as the peeling or cracking of the coating on the lens surface, the deformation of the frame that cannot be restored, and the fading of the frame (especially in the parts that touch the skin) will all affect the visual effect and the wearing comfort. So it is recommended that adults change their glasses every 2 to 3 years.

*Adults also need to have an eye examination once a year to detect eye problems in a timely manner and achieve early detection and early prevention.

It is recommended that middle-aged and elderly people change their glasses every 1 to 2 years.

After the age of forty, many people begin to experience "presbyopia", which is the decline of eye accommodation that we often talk about.

It is a physiological phenomenon that occurs when people reach a certain age, and the degree of presbyopia will change every year. So when the glasses being worn can no longer ensure clear vision and the eyes feel sore and uncomfortable, glasses should be changed in a timely manner.

In terms of the cycle, it is recommended to change glasses once every 1 to 2 years. When having glasses fitted, try to choose professional institutions for professional optometry and don't buy ready-made glasses casually.

Everyone's specific situation is different, and the frequency of reexamination and changing glasses also varies from person to person. It is recommended that everyone have regular eye examinations and choose whether to change the lenses under the advice of a professional optometrist.
