Introduction to swimming glasses
Swimming goggles are a kind of equipment in swimming. They are tightly fastened to the eyes when used. When swimming, they can see things clearly under the water and prevent the water in the swimming pool from entering the eyes. They are necessary items for many swimming enthusiasts and also bring a lot of fun to swimming.
In terms of functions, goggles can be divided into: racing goggles, ordinary goggles, near-sighted goggles, and presbyopic goggles. Good goggles also have high-performance anti-fog, 100% anti-ultraviolet treatment and sealing functions, which can better protect eyes and prevent injuries.
A swimming mirror, generally including six parts: frame, frame, lens, waterproof rubber ring, elastic adjustment buckle, and mirror belt.

A swimming mirror, generally including six parts: frame, frame, lens, waterproof rubber ring, elastic adjustment buckle, and mirror belt.
spectacles frame
The part connecting the lens, lens belt and lens frame. The material is usually PC. The frame, frame and lens are generally integrally molded with PC materials. However, some conjoined frames do not have a nose support, and they are made of soft materials.
Mirror frame
PC material, used to fix the lens, is also the attachment point of waterproof rubber ring.
Lens
PC material, high transparency, relatively scratch resistant, providing good transparency and visibility. Generally, the swimming goggles are high-grade. The goggles lenses are generally fog-proof, and most of them are electroplated, which can better protect the eyes from ultraviolet rays, and are more suitable for outdoor swimming.
Waterproof rubber ring
Its main function is to block water and small sundries in the water from entering the eyes. Secondly, the rubber ring is generally made of soft material (silicone), which is in contact with the face, improving the comfort of wearing. Waterproof rubber ring is generally made of silica gel or rubber material. Silica gel can be divided into liquid silica gel and solid silica gel. Rubber can be divided into general rubber and special modified rubber. Different materials have different bonding tightness with PC, and the surface texture of aging resistance and yellowing resistance is quite different.
Elastic adjusting buckle
It is used to adjust the tightness of the goggles belt to make it suitable for wearing.
Mirror band
Use it to fix the goggles on the head. The materials are mostly silica gel, and some are made of cloth.
Color selection of swimming goggles
1. Transparent color goggles provide protection and clear vision without changing color, which is the choice of many people.
2. Smoke color goggles can reduce the light transmitted into the naked eye and reduce the brightness without changing the color too much.
3. Blue lens goggles can reduce the reflected strong light on the water surface and maintain good visibility under indoor brightness conditions.
4. The lavender and pink swimming goggles can make the objects under the blue or green background appear particularly prominent and suitable for outdoor activities.
5. Yellow and orange goggles, blue removed from the color spectrum, all things look clear and bright, suitable for indoor use.
Precautions for purchasing swimming glasses
- Transmittance
When swimming, because the water temperature is relatively low, glasses are easy to fog, which will affect the sight. When selecting glasses, you should choose the mirror material with good hydrophilicity, so that it can absorb moisture and prevent it from condensing into fog. Antifogging agent for swimming goggles can also be bought on the market, which is also an effective way to prevent the fog on the mirror surface.
- Check the tightness
When selecting glasses, try to wear goggles to feel whether the sealing ring is absorbent and will not make the eyes feel tight. The sealing ring of good swimming glasses can not only reduce the penetration of water, but also relieve the impulse of the eyes in the water without causing pain to the eyes.
- Look at the material
There are many materials for swimming goggles. Because there are several parts of the goggles, the materials are different. Generally, the head wear, nose bridge and frame of the goggles are made of silicone material. The advantage of this material is that it is very soft and the skin will not feel pain when wearing. The lenses are made of glass, resin, silica gel, plastic, etc. The lenses of better swimming glasses are made of a combination of reinforced glass and silica gel, and the price is relatively expensive; The cheaper one is made of plastic.
- Viewing degree
Some people are short-sighted, but it doesn’t matter. Now there are special short-sighted swimming glasses, which are suitable for those short-sighted people. When you buy swimming glasses, you should select them according to your personal situation. A good pair of short-sighted swimming glasses is in line with medical standards, and will not affect your vision.
