Generally speaking, many people will find that their vision begins to decline gradually when they are nearly 50 years old. The most typical manifestation of presbyopia is that you must move away from the newspaper to see clearly. The accommodative power of the ciliary muscle becomes weak, and this change progresses slowly throughout a person's life.
The elderly generally need to wear reading glasses when they have the following symptoms. Generally, reading glasses on the market can be divided into bifocal reading glasses, progressive reading glasses, and foldable reading glasses.
1. When reading, you need to take the book far away, or you need to read in a bright place to see clearly.
2. Eye fatigue is common. And due to over-adjustment of the eyes, eye swelling, headache and other symptoms of asthenopia may occur.
3. For nearsighted people, it is necessary to take off the glasses or stretch the reading material when reading at close range, which is also a manifestation of presbyopia. Nearsighted reading glasses will help you a lot.
In the annual eye examination, ask the ophthalmologist what reading ability and diopter you need. This can help you wear good quality reading glasses with the right degree.
First, you need to understand what kind of reading glasses lens you need.
The bifocal reading glasses have an unamplified lens. For people who like to wear a reader all day or who often go from reading to farsightedness, this lens has the highest adaptability.
The magnifying glass for reading is best for people who only wear the reader when they need it.
For people who use computers or other digital devices for a long time, eyekepper computer glasses are the best choice.
It is recommended to use progressive multifocal reading glasses or polarized reader sunglasses when going out to protect your eyes from the sun’s UVA/UVB rays.
Secondly, you can choose to customize reading glasses according to your own needs. It includes the color, pattern, width, and shape of the frame.
Some people think that reading glasses are just a frame with two glasses, and you can buy a pair of cheap reading glasses in bulk at any stall. There are even old couples wearing the same pair of reading glasses, which is a wrong approach.
Go to a professional institution to fit reading glasses. After the symptoms of presbyopia appear, it is best not to be afraid of troubles. You need to conduct professional optometry inspection and fit your own reading glasses. You can choose ordinary reading glasses or multifocal progressive lenses with gradual diopter from top to bottom.
As the age increases, the degree of presbyopia will increase. Once the reading glasses are not suitable, they must be replaced in time, otherwise it will increase visual fatigue.
For 40-55 years old, refraction is performed every two years to see if the presbyopia is deepened or the lens refractive changes. If the presbyopia lenses are scratched or aging, the light transmittance will decrease, which will affect the imaging quality of the lenses.
