How to choose glasses
Recently, a well-known ophthalmologist in Xi'an died of illness, which attracted the attention of the general public. In our daily life, many people are facing eye health problems. Glasses have become an important tool to solve these problems. However, there are many kinds of glasses on the market. How to choose the glasses that are suitable for you has become a headache. This article will elaborate on how to choose glasses from four aspects.
Know your glasses
The first step in buying glasses is to know the degree of your glasses. The glasses are divided into myopia and hyperopia, and the corresponding glasses are myopia glasses and hyperopia glasses respectively. To accurately measure the degree of glasses, it is best to go to a regular eye hospital for inspection to accurately determine the degree.
On this basis, we should also consider whether there are other vision problems, such as astigmatism, presbyopia, etc. According to personal conditions, choose the lens suitable for yourself to ensure normal vision.
In addition, it is also necessary to check the glasses' degree regularly, because the glasses' degree may change with age and vision.
Choose the right frame style
Frame style is one of the important factors to consider when selecting glasses. The frame style can be selected according to the face shape, personal preferences and usage habits. Generally, people with long and thin faces are suitable for round or square frames, while people with round faces are suitable for slightly angular frames.
In addition, the size of the frame should also be considered, and the appropriate frame size should be selected to ensure that the lens can cover the entire field of vision without causing discomfort to the face.
The material of the frame is also a concern. The common materials of the frame are metal, plastic and titanium alloy. Select suitable materials according to personal needs and budget.
Understand the material and function of lens
Lens is the core part of glasses, which determines the visual comfort and visual effect of glasses. At present, the common lens materials on the market are resin, glass and advanced lens materials.
The resin lens is relatively light and has good impact resistance, which is suitable for daily use. Glass lenses have good scratch resistance, high refractive index, clear vision, and are suitable for special needs. Advanced mirror material has higher light transmittance and better anti blue light function, which is suitable for people who use electronic products for a long time.
In addition, there are also some lenses with anti ultraviolet, anti glare, anti blue light and other functions, and suitable lens functions can be selected according to personal needs.
Select suitable glasses according to personal needs and budget
Finally, choose suitable glasses according to individual needs and budget. If glasses are needed for special occasions, such as sports and driving, professional sports glasses or driving glasses can be selected to meet special needs. If the budget is limited, you can choose a high cost performance glasses brand or get a pair of classic glasses.
No matter which kind of glasses you choose, you should ensure the quality and safety of the glasses, choose a regular glasses store or brand, and avoid buying low-quality glasses that will harm your eyes.
Summary
Choosing glasses is a complex and important task. In order to ensure that we can purchase the right glasses, we can choose from the following aspects: knowing the degree of our glasses, choosing the right frame style, understanding the materials and functions of lenses, and combining personal needs and budget. Only by purchasing glasses that are suitable for you can you better protect your eyesight and eye health.
