Do lenses also have a shelf life? Don’t wash and scrub too old

[Community Hot Discussion] column is online. The column will sort out the pan-health content that everyone is paying attention to recently from the “Dr. Clove App”. The content has a large space for discussion, and the hot comments are also interesting and sharp. Sections will be launched regularly.

This issue is issue 6. Looking forward to one day your sharing can also appear in the column.

Myopia is a common eye disease in today’s society, and myopia glasses are a must-have item for myopic patients. Glasses look good in the frame, the key lies in the lens, but the consequences of not changing the lens for a long time may be worse than expected. No, community netizen @open pickup’s pudding has something to say.

Recently, a friend told me that he often has eye pain and can’t see clearly. After inquiring, he found out that he has been wearing glasses for 9 years.

He went to the hospital for examination and was diagnosed with visual fatigue. The preliminary judgment was that the lenses had not been replaced for a long time, and the degree of prescription did not meet the eye discomfort.

The doctor also shared with him the common phenomena and consequences of not changing lenses for a long time.

1. The lens is yellow

Reduce visual clarity, increase the burden on the eyeball, and deepen the degree of myopia.

2. There are scratches on the lens release film

Affects the refraction effect and optical correction performance of the lens, and loses the effect of improving vision.

3. Degree does not match

The degree of myopia does not match the previous degree of myopia, and symptoms such as blurred vision, dizziness, and eye pain occur.

In addition, the doctor also reminded that if the lens is not replaced for a long time, it is easy to make the eyes tired, sore, sore, and in severe cases, it may even cause a series of eye diseases.

In the words of doctors, lenses also have a shelf life.

How often is a reasonable lens change?

Adolescents: It is recommended to replace the lenses every six months to one year. Adolescents are in the peak period of eye use, and the degree of change at this age is relatively faster.

Adults: It is recommended to replace the lenses once a year and a half. The normal service life of ordinary resin lenses is generally about one and a half years.

Senior: Regular replacement is recommended. Older reading glasses also need to be replaced regularly. However, because the power of reading glasses increases slowly, there is no strict time limit.

Of course, I understand that everyone’s situation is different, and the frequency of rechecks and lens replacements varies from person to person. There are also some friends who may not be able to replace them on time due to price factors.

Here I will add an affordable way to get glasses: first go to a professional eye hospital for optometry, get a prescription for glasses, and then buy online according to the prescription, which will be cheaper in comparison some. However, online purchases may have quality risks, and you should evaluate by yourself.

I was wearing glasses five years ago, and I can’t see clearly now, but I’m too lazy to change it, and my refraction must be high again, and I feel uncomfortable.

Open pickup pudding Answer: Don’t delay your eyes just because you feel uncomfortable for a while.

Every time I go to the optical shop to wash my glasses, I put them in a small ultrasound machine, and they can be washed very cleanly. When I was in college, I put my glasses on the ultrasonic cleaning machine in the laboratory once, and the effect was exactly the same. Engineering friends can try it.

The glasses I just got don’t take long, I put them in my bag when I don’t use them, and then the lenses get scratched… I just took them off and took a look, they’re the same as the pictures, I need to change the lenses Expensive, friends who are not short-sighted must take good care of their eyes.

I changed every four years in college, and it all brought out my feelings. It is also the right eye that has increased the degree, and it feels a little blurry before I change it.

Is online distribution reliable? I am highly short-sighted, and every time I wear glasses, I have to pay less than 2,000 yuan, which is a little distressing.

Dark volute A: I bought it. If you are not too troublesome, you can indeed optometry offline and buy online. Going to a special store for optometry is only a few dozen yuan, and then choose a store with high shipment volume and high praise rate online.

That’s all for now.
