How to choose reading glasses for people with myopia presbyopia? 50

Before wearing reading glasses, you should go to the hospital for a comprehensive eye examination, including distance vision, near vision, intraocular pressure and fundus examination. Cataracts, glaucoma, and some fundus disorders should be ruled out before refraction can determine the prescription. The prescription of presbyopia varies with age, so it is best to go to optometry every three to five years and do not wear glasses that are too shallow for a long time.

How to get glasses for myopia and presbyopia.

It needs to be selected according to the degree of eye aging. The adaptation degree of reading glasses is not fixed, in addition to the different degrees of presbyopia, there are also ** different distances. Generally, the prescription of glasses according to age refers to the most comfortable and clear object 30 cm away from the eye.

In the application, if you look at a close and small object, the power should be a little higher, if you look at a distant and large object, the power should be a little lower, for example, when I look at the mobile phone, it is generally suitable for 300 degree glasses, when looking at the large screen of the computer, the distance of about 1 meter is suitable for 50 degrees, and when it is 70 cm, it is suitable for 100 degrees. If it is interchanged, it cannot be used at all, and it is not good for the eyes for a long time. Therefore, it is best to choose glasses with different powers according to different scenes, and now ordinary glasses are not expensive, it is best to buy a few more pairs of glasses with different powers according to your own situation to adapt to different scenes.

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

There are three main types 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, these glasses have strict requirements for optometry, try-on, processing and frame selection, and it is not possible to 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.

Reading glasses for both near and far purposes are currently mainly aimed at people who have myopia or farsightedness in their eyes and already have presbyopia. However, whether it can be worn or not, whether it is suitable for wearing, can only be determined after going to the hospital for accurate optometry, and it is not recommended to wear it blindly.

First of all, people who wear these glasses often have other vision problems such as myopia or farsightedness, and their eyes are not simply presbyopia. Simply wearing one type of lens will not meet the needs of everyday life.

Secondly, the degree of presbyopia in the two eyes may be different, and the power of the reading glasses that need to be worn will be different, while the power of the two lenses of general reading glasses is the same.

Finally, middle-aged and elderly people who are more responsible for eye problems should also cooperate with oral Lejing blueberry lutein to supplement eye nutrition, relieve eye fatigue, and prevent the occurrence of other eye problems.

You can only look close, look far and misty, don't be fooled, I just delivered to a pair, I inspected the goods not at all on the Internet, I just didn't pay and left.

Hello, your eyes should be farsighted, it is recommended that you go to the hospital for an optometry examination, according to the results of the refraction with a moderate number of glasses.

It should be suitable for people who have had myopia when they were young, because it seems that presbyopia is a kind of farsightedness, and those who have myopia will offset and reduce some of the presbyopia, but it will not be completely reduced, that is to say, presbyopia and myopia will coexist.

Many middle-aged and elderly people think that reading glasses don't need to be too particular, you can buy a pair for 10 yuan on the street, and you can see it clearly. Moreover, reading glasses are only used occasionally, so there is no need to spend time and energy to specifically check the prescription after optometry.

However, everyone's eye condition is actually different, and the prescription of reading glasses should be adjusted according to the original condition of a person's eyes. The reading glasses that cost 10 or 20 yuan on the street are all fixed, and they are all finished products such as 100 degrees, 150 degrees, 200 degrees, etc., and are not customized for individuals.

Before wearing reading glasses, you should do a comprehensive examination of your eyes, including fundus and intraocular pressure.

Examination and measurement of near and distance visual acuity. To rule out cataracts.

Glaucoma and some fundus diseases can only be determined by refraction.

Moreover, with the increase of age, the degree of presbyopia will also deepen, once the reading glasses are not suitable, they must be replaced in time, otherwise it will bring a lot of inconvenience to the life of the elderly, and it will also accelerate the aging of the eyes. At the same time, reading glasses lenses.

The life of the lens is also limited, and after a long period of use, the lens will be scratched and worn, resulting in a decrease in light transmission and affecting the imaging quality of the lens.

When choosing reading glasses to wear, pay attention to the choice of frame, lens and prescription. It is recommended to choose a non-metallic or lightweight metal frame, which can reduce the weight of reading glasses and make them easy to wear. If you like to play with your mobile phone or play outdoors, you can choose lenses that prevent blue light and UV rays.

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.

The key points for choosing the right reading glasses are: go to a regular institution or hospital for examination and optometry, go to a regular place to buy reading glasses, choose the right reading glasses, choose the right lens material, and pay attention to the comfort of the frame.

1. Go to a regular institution or hospital for examination and optometry: When there are symptoms of unclear vision, it is necessary to go to a regular institution or hospital for examination and optometry in time.

2. Go to a regular place to buy reading glasses: Many elderly people like to buy a pair of reading glasses at the stall in order to be cheap and reluctant to spend money.

3. Choose the right reading glasses: Whether it is when choosing a frame or lens, you must choose the one that suits you. In addition, the prescription of presbyopia will increase with time, remember to replace the lenses in time, and replace the glasses in time if they are aging.

4. Choose the right lens material: The lens material of reading glasses has a variety of options such as ordinary resin, advanced resin, glass, etc. Ordinary plastic lenses are lightweight and comfortable, and the cost is low, but they are not tough enough; High-grade plastic lenses have better impact resistance and are more expensive at the same time; Glass lenses, on the other hand, are dense and hard, but fragile and heavier.

Therefore, when purchasing, you need to choose the right lens material according to your own situation and needs.

5. Pay attention to the comfort of the frame: The comfort of the frame is also very important, which affects the comfort of wearing reading glasses. Choose the right frame material, such as pure titanium, metal, plastic steel, etc.

Also pay attention to the proper size and shape of the frame to avoid pressure or discomfort to the ears and nose.
