What are the types of glasses?

There are many types of glasses, which can be roughly divided into the following categories according to their functions, designs and materials:

Myopia glasses

Glasses correct myopia by reducing the intensity of the light the eye focuses on. The lenses are thicker in the center and thinner at the edges, allowing distant light to focus on the retina after refraction.

Hyperopia glasses

Hyperopia glasses correct hyperopia by increasing the intensity of the light your eyes focus on. The lenses are thinner in the center and thicker at the edges, allowing light from nearby refracts to focus on the retina.

Bifocals

Segmented bifocals divide nearsightedness and farsightedness into two areas, usually the upper part is farsightedness and the lower part is nearsightedness. Progressive bifocals are a transition area of gradual change, which can gradually transition from farsightedness to nearsightedness, which is more natural and comfortable.

Reading glasses

Reading glasses are mainly used to improve the near vision of middle-aged and elderly people, especially when reading vision problems. The upper part of the lens is used for farsightedness and the lower part for nearsightedness.

Sunglasses

The lenses of sunglasses usually have ultraviolet protection, which can effectively block harmful ultraviolet rays from the sun and reduce the irritation of the eyes from strong light, while also helping to reduce eye fatigue.

Sports glasses

Designed to be worn during exercise, it usually has lightweight, non-slip, shock-proof and other characteristics to ensure that the glasses are not easy to fall off or be damaged during intense exercise, protecting the eyes from external damage.

Blue blocking glasses

Anti-blue glasses reduce the stimulation of blue light emitted by electronic devices (such as computers, mobile phones, etc.) through special lens technology, which helps to reduce eye fatigue and improve sleep quality.

Goggles

Goggles are usually made of special impact-resistant materials, which can effectively prevent the damage of external objects to the eyes, and are suitable for industrial, laboratory and other environments.

Contact lens

Contact lenses are clear lenses placed directly on the surface of the eye that correct vision problems by changing the curvature of the front surface of the cornea, and are suitable for people who do not like to wear glasses frames. Common contact lenses include hard contact lenses and soft contact lenses.

Each type of glasses has its own characteristics and application scenarios, choosing the right type of glasses needs to take into account personal vision, lifestyle and doctor’s advice.

Then let’s learn how to choose glasses

Learning the shape of your face and the width of your nose

The shape of the face and the width of the bridge of the nose are important factors in determining the right type of glasses. Generally speaking, people with rounder faces are suitable for square or rectangular frames; People with longer faces are suitable for slightly wider frames; People with higher nose Bridges can choose glasses with thinner nose pads, so as not to press the frame to the nose bridge; People with a lower nose bridge are suitable for glasses with thicker nose pads to increase the support of the nose bridge.

Choosing the right frame material for you

It is also important to choose the right material for your frame. Generally speaking, plate frames are light and wear resistant, but easy to deform; Metal frame texture is strong, not easy to deformation, but relatively heavy. Therefore, you can choose according to your needs and preferences.

Trying on glasses

Trying on glasses is a very important step. Before trying it on, you should first determine the number of lenses you need and the size of the frame that suits you. When trying it on, pay attention to comfort and whether the frame fits perfectly with the face shape and the bridge of the nose. At the same time, pay attention to whether the tightness of the frame is moderate, so as not to slide the frame after wearing it for a long time.

Considering the brand and after-sales service of the glasses

When choosing glasses, in addition to style and quality, brand and after-sales service are also very important factors. Generally speaking, the quality and after-sales service of well-known brands are relatively guaranteed, but the price is also relatively high. Therefore, you can choose your own eyewear brand according to your economic strength and needs.

Finally, let’s know what to pay attention to wearing glasses?

Changing glasses regularly

Cleaning lenses properly

When cleaning the lens, you can first rinse with water, and then wipe with paper towels, or wipe with a special glasses cloth to avoid dry wiping the lens, so as to avoid grinding the lens.

Just-in-time screw

In daily life, we should pay attention to check the screws on the frame, if loose, should be tightened in time. The frame should be repaired in time after deformation.
