How to wear reading glasses for the elderly with myopia

This article tags:How to wear reading glasses for eye health With age, the elasticity of the lens capsule decreases, the lens nucleus enlarges and hardens, the ciliary muscle weakens, and the regulatory power decreases and presbyopia appears. Presbyopia is a normal physiological phenomenon, just like a person's hair turns gray when they reach a certain age.

Some elderly people with myopia do not need to wear reading glasses, and they can read and write every time they take off their glasses. However, there are also some myopia patients who cannot see near without reading glasses, and need to wear a pair of reading glasses to read and write. What's going on?

The eyes of myopia patients also have aging, and they also have presbyopia, but the presbyopia of myopic patients happens to be neutralized by the myopia, so presbyopia is later than that of people with normal eyes, and it is generally possible to not wear reading glasses or only wear a pair of low-power reading glasses. Some people say that people with myopia greater than 400 degrees will never have presbyopia. But in fact, it is not necessarily, because the adjustment power of the human eye varies greatly from person to person, which is why some myopic patients need to wear reading glasses when looking closely, even if they have a high degree of myopia.

How to choose reading glasses? The most common way to correct presbyopia is to wear reading glasses. Reading glasses are a kind of biconvex lens, which can supplement the lack of eye accommodation and achieve the purpose of correcting presbyopia.

Before fitting glasses, you should go to a regular hospital for optometry and check whether you have other eye diseases, determine whether you have myopia, farsightedness and astigmatism, and then increase or decrease the refraction according to age and presbyopia. If you have astigmatism, you need to integrate the astigmatism power into the reading glasses when you wear glasses. Of course, when fitting glasses, it is necessary to increase or decrease the power of the lenses appropriately in combination with the working distance that the patient is used to, and if the working distance is close, the power of reading glasses should be appropriately increased.

Conversely, the power should be lowered appropriately.

How to get glasses for myopia and presbyopia.

The degree of myopia and presbyopia varies from person to person.

There is no general number of degrees.

If you want to buy presbyopia, it is best to have glasses based on the refraction data after refraction.

Let's not ignore the existence of the elderly

1. When matched, do not delay presbyopia is a normal physiological process, and the degree of presbyopia is related to age. For example, at the age of 45, presbyopia is +, i.e., 150 degrees), and at the age of 50, whether you wear glasses or not, presbyopia will increase to +i.e., 200 degrees). If you have already seen presbyopia, if you don't wear reading glasses, you will not be able to adjust the exhaustion of the ciliary muscles, which will definitely aggravate reading difficulties, produce dizziness and swelling and many other symptoms, and affect your life and work, which is very unwise.

So, read glasses should be fitted immediately, and don't delay. As you get older, the prescription of your reading glasses is not enough, so you need to replace them in time.

2. Reading glasses should also be refraction first. Some elderly friends have inconsistent presbyopia in their eyes, or they still have farsightedness, myopia, and astigmatism, so they don't experience light and buy a pair of reading glasses to wear, which not only can't solve the problem, but also cause double vision, eye swelling, and vision loss. Even if the vision of the two eyes is relatively consistent, it is necessary to accurately refraction and reasonably determine the power according to the remaining adjustment force of the eye.

This allows for a certain amount of accommodating power, making it easier to use your eyes at close range. What's more, the pupil distance between the two eyes of each of us is not the same, and the interpupillary distance is smaller when reading than when looking far, which can only be accurately determined by optometry.

3. Wear reading glasses to consider the needs and habits of use. Reading glasses are also known as:"Ruler mirror"That is to say, after wearing reading glasses, the near point can be moved forward to the general reading distance of 1 foot, that is, about 30 centimeters. However, if your workbench is relatively low, or you are engaged in machine maintenance work, then the proximity point should be more than 30 cm; Conversely, if you work closely, the periapsis is within 30 centimeters.

Therefore, when wearing reading glasses, you should explain your needs to the optometrist and adjust the prescription of the lenses appropriately. Some middle-aged and elderly people need the help of glasses to see far and near, so they need to wear two pairs of glasses. If you think two pairs of glasses are too troublesome, you can also choose multifocal gradient lenses with increasing diopters from top to bottom, and a pair of glasses is suitable for seeing far above and near at the bottom, which will be more convenient to use.

It is suitable for people of all ages with myopia, myopia and astigmatism.

There are three kinds of reading glasses on the market, namely single vision lenses, bifocal L lenses and progressive multifocal lenses. The monofocals can only be used to see close, and you need to remove your glasses to see far.

The so-called far-near and far-purpose smart reading glasses are progressive multifocal glasses, that is, between the far light area and the near light area of the lens, they are organically connected in a gradual change of diopter, and the wearer can see the distance through the visual distance area above the lens when looking forward, and read the newspaper and mobile phone through the near vision area under the lens when looking down.

It is true that wearing these lenses allows you to see far and near with only one pair of glasses, but not everyone is suitable for wearing them. In addition, this type of glasses has strict requirements for optometry, try-on, processing and frame selection, and it is not possible to simply provide the two parameters of power and interpupillary distance to be successfully fitted.

There are hidden dangers in buying glasses online: there is no professional optometrist to detect and determine the appropriate prescription of glasses; The quality of the lenses and the frames cannot be tried on the spot, and the quality and after-sales are difficult to guarantee.

Therefore, it is advisable for the public to go to a regular hospital for professional optometry to determine the prescription, and try it on, and a professional optometrist will confirm whether it is suitable for wearing and whether it can be adapted.

Go to the hospital or a regular optical store for optometry, take the list to match glasses, and of course, you can also take the list to a certain treasure to match.

If you have low-grade myopia, although the distant scenery is still clear when you wear myopia glasses, you can't read and write as "vividly" as before, and you can see it really when you take off your glasses, which is dazzling, which is called presbyopia in medicine. It means that it is time to wear reading glasses. Presbyopia is not just a matter of finding reading glasses and putting them on, but it is very particular.

At present, there are two kinds of prescriptions for reading glasses: one is to add 1 3 adjustment power to the prescription of glasses that are close (33cm) and clear for reserve; The other is to use the lowest lens power to see at close range (33 cm). The practice of many older people proves that the latter is better.
