Many people don’t understand this disease that almost all parents have!

Are your parents starting to get presbyopia?

According to the survey data of "2018 Market Scope", about 56.9% of the Chinese population aged 35 and above have presbyopia, reaching 390 million.

In other words, nearly 30% of people in the country suffer from presbyopia.

The reality is that people don’t pay nearly as much attention to presbyopia as they do to myopia: it’s something that happens as we age.

After parents discovered that they had presbyopia, most of them chose to go to roadside shops or Pinduoduo to buy a pair of reading glasses for 9.9 yuan with free shipping, rather than going to regular eyewear stores for strict eye examinations and fittings.

But did you know that although presbyopia is common, it cannot be treated casually?

It is not recommended to buy and wear reading glasses casually! Otherwise, it may affect your vision and may delay the treatment of other eye diseases and lead to blindness.

Today, we join ophthalmologist Lin Danni to talk about presbyopia.

Friends have been asking if presbyopia can be prevented, and we have also arranged some super practical methods! Be sure to read to the end

I don't know when I went home, but I found a pair of reading glasses on my parents' desk. When I asked, I found out that they were crystal reading glasses bought at a small shop at the entrance of the vegetable market for 9.9 yuan.

"These glasses are very cheap! They are drop-proof and allow for very clear vision!" My parents even told me with a little pride.

After surveying my colleagues, I found that this is the norm for our elders.

Some were bought in street shops, some were bought on Pinduoduo and Taobao, and the better ones would go to a special glasses store to try on a few pairs.

But it is not recommended to wear reading glasses casually! The consequences are much more serious than we think. There are three reasons:

With this kind of "big currency" glasses, getting them is easier than buying clothes.

When buying clothes, you still need to know your height, weight, and style preferences, but these stores only need age to match the degree:

When parents buy glasses, they usually try on a few pairs and only buy the ones they can see clearly; some couples even share a pair of glasses.

However, the degree of presbyopia varies from person to person, and the conditions of the left and right eyes are also different. Therefore, the degree of the glasses you buy may be quite different from the actual degree.

Wearing this kind of glasses can help you see clearly in the short term, but in the long run, it will not only fail to relieve eye fatigue, but may even aggravate presbyopia.

Pupillary distance refers to the distance between the pupils, which is the distance between the centers of the two pupils when our eyes are looking straight ahead.

Measuring the pupil distance is an essential step in optometry. Whether glasses are comfortable to wear has a lot to do with the accuracy of the pupil distance.

But the glasses sold in street shops have fixed pupil distances and cannot be customized.

Wearing glasses with inappropriate pupil distance can cause dizziness, nausea, and distorted vision, which will greatly affect the comfort level during wearing.

Wearing such glasses for a long time may even cause strabismus and affect vision.

In addition, some elderly people may have myopia, astigmatism or other problems, which require specially customized glasses to solve.

The decline in vision among the elderly is not necessarily due to presbyopia. It may be accompanied by other eye fundus diseases, such as cataracts, glaucoma, age-related macular degeneration, etc.

If you just wear a pair of glasses, the problem of blurred vision may be temporarily alleviated, but there is a high possibility that potential eye diseases will be ignored.

Taking the above factors into consideration, we strongly recommend that friends with presbyopia symptoms go to a regular eyewear store and have a strict eyesight test before getting reading glasses.

Going to a regular optical shop to get glasses generally requires the following steps:

Let’s first look at the causes of presbyopia: As we age, the lens of the eye gradually hardens and thickens, and the ability of the eye muscles to adjust decreases, resulting in a decrease in the eye’s ability to focus.

Specifically, when we look at objects at close range, our vision becomes blurred.

Myopia is caused by the prolonged contraction of the eye lens and its inability to relax, which results in the inability to see distant objects clearly.

Because of their different causes, presbyopia and myopia cannot cancel each other out, so people with myopia will gradually develop presbyopia as they age.

At this time, you can choose to wear two pairs of glasses: one pair of myopia glasses for seeing far away and one pair of reading glasses for seeing near. If you find it troublesome, you can also wear a pair of special progressive multifocal lenses:

It is a pair of glasses specially designed for people with myopia and presbyopia, which can see clearly both near and far objects:

Looking forward is used to see far away; looking downward is used for medium and close distances, such as reading and walking.

The disadvantage is that it is more expensive than ordinary myopia glasses.

A friend has been sending me a private message: Dad Wei, presbyopia is so troublesome, is there any way to prevent it? Let me tell you the good news: it can be prevented!

Doing more exercises to train the eye muscles can effectively prevent presbyopia.

For example, in table tennis and badminton, the eyeballs need to follow the ball's movement back and forth during the exercise, which can effectively exercise the eye muscles.

If you are not good at ball sports, you can also consider buying a double-sided mirror flip racket to practice at home.

This is a common vision training method in ophthalmology. It has two lenses, the positive lens simulates looking far away, and the reverse lens simulates looking near. Training back and forth several times a day can also effectively adjust the eye muscles.

However, we also want to remind everyone: presbyopia is like wrinkles on the face and white hair on the head. No matter how you prevent it, it will come "although late."

If your parents have mild presbyopia, you can take these measures to relieve the symptoms:

Special large print version, remember to save and forward to your parents

Most of the elders are frugal, and many of them are unwilling to go to the optical shop to get glasses out of the mentality of "I'm old, there's no need to buy something too good".

So we hope that everyone will not just forward this article casually. Why not take your parents to a regular optical shop/eye hospital this week and get a pair of suitable reading glasses?
