How many pairs of eyeglasses do you have? How often do you change your eyeglasses? The question of how long to use glasses can be significantly different. Some people rotate several pairs of glasses, while others don't replace them until they break. Do you know how long the shelf life of a pair of eyeglasses is?
Adults, in particular, think, "my prescription may not go up." So as long as their glasses are still working, they won't go for a new pair of prescription eyeglasses unless they've been crashed or broken by sitting.
Here, we would like to say to those whose eyeglasses are not broken for a long time and have not changed: Wrong! Very wrong!
First of all, we live together with our eyeglasses, with a long time easy to loosen or deformation. Secondly, the lenses are prone to yellowing, scratches, cracks, and other problems under prolonged consumption. Third, the prescription may also rise in adulthood; with the growth of the old prescription, the lens of eyeglasses can not meet the needs of the eyes' precise correction. So, more and more implications come with it—for example, frame deformation, which can affect the comfort of wearing. In addition, lens wear affects the clarity of vision, causing poor vision; long-term wearing of blurred eyeglasses quickly causes visual fatigue to accelerate myopia development.
In short, for eye health, it is necessary to change glasses regularly. However, the use cycle of eyeglasses is different for people of different ages.
Eyeglass use cycle for Children and Teenagers
Children and teenagers are in the growth and development period, the need for close eye use is significant, and myopia is easy to deepen. Therefore, after the child wears eyeglasses, it is best to review the optometry every six months, according to the change of prescription, timely change, and adjust the parameters of glasses.
Parents should pay more attention to the change in their child's prescription, but also to the structural and strength integrity of the eyeglass frames and the wear and tear of the lenses. Scratched and broken lenses can affect their corrective function and the visual effect of the eyes. Therefore, they should be replaced in time, as recommended by the optometrist, to ensure that the child can use the eyes comfortably and permanently.
Adult eyeglasses use cycle
Generally speaking, the prescription for adults is relatively stable, but it does not necessarily mean that it will not change. It is recommended that adults have at least one optometric examination per year. The reason is firstly to understand their eye health and vision; Secondly, to check the wear and tear of their glasses and make a comprehensive assessment of whether to replace their existing eyeglasses in conjunction with their daily eye environment and habits.
Elderly eyeglasses use cycle
First, it is essential to emphasize that presbyopic eyeglasses are never just bought by the supermarket and put on! The deepening of presbyopia is relatively slow, and the frequency of use is relatively low, so you can generally replace your eyeglasses once every 1-2 years. However, suppose a middle-aged or older adult is already wearing presbyopic eyeglasses, and they feel fatigued when reading. In that case, there may be a situation where the glasses prescription is inaccurate. So it is recommended that you seek medical attention promptly and have your doctor examine you to determine if you need to replace your glasses or if there is a possibility of other eye diseases.
In addition, the risk of cataracts, glaucoma, and dry eye is relatively high in old age, so it is recommended to have an eye examination every six months to a year.
In the above, you can find that in addition to the change in prescription, there is an important point that affects the life of the glasses, that is, the deformation and loosening of the frame, which requires us to do an excellent job of daily maintenance of glasses.
