Whether you are swimming in an indoor pool, challenging outdoor waters, or practicing hard in a training ground, a pair of suitable swimming goggles is an indispensable partner. The following is a guide to buying swimming goggles to help you choose the swimming goggles you like.
1. Anti-fog performance of the lens
Anti-fog is one of the core performances of swimming goggles.
High-quality swimming goggles usually use a special anti-fog coating. The hydrophilic substance in the coating can make the surface of the lens form a super-hydrophilic property, so that small fog droplets will quickly spread to form a water film once condensed, avoiding the fog from beading and affecting the vision.
Adding hydrophilic materials to the lens material, such as hydrophilic materials made of fluoride, can effectively prevent water from condensing into fog on the surface of the lens, allowing water to spread evenly on the mirror surface with surface tension to form a water film, achieving an anti-fog effect. For example, a lens material made of polycarbonate matrix resin and fluoride hydrophilic materials can achieve better anti-fog performance.
Optical anti-reflection materials with multi-layer film system design can achieve high transmittance and low reflectivity in the visible light range, reduce the condensation of fog on the surface of the lens, and improve visual clarity and comfort.
By using special technologies such as plasma treatment on the lens surface, the physical and chemical properties of the lens surface can be changed, which can enhance its anti-fog performance, make the lens more hydrophilic, and reduce fog adhesion.
In addition, the anti-fog lens made of the anti-fog lens body and the polarized lens can not only prevent fogging, but also reduce water surface reflection and glare, thereby improving the visual effect. However, due to its high technical threshold and expensive material cost, the price of polarized lenses is relatively high.
When purchasing, you can check the product description or consult the store clerk to understand the durability of its anti-fog effect. Applying anti-fog agent before use can also enhance the anti-fog ability of some swimming goggles, but be careful to choose products that are harmless to the eyes.
2. Comfort of the frame
The material and design of the frame are directly related to the comfort of wearing.
Silicone frames are a common and popular choice. They are soft and fit the contours of the face. They can ensure good sealing performance and prevent water leakage without causing excessive pressure on the facial skin. When trying on the glasses, pay attention to the fit of the frame around the eye sockets, the bridge of the nose, and the temples. There should be no obvious tenderness or gaps.
3. Lens clarity and color
Lens clarity determines the quality of vision in the water.
You should choose lenses with good optical properties and no obvious deformation and chromatic aberration. Polycarbonate lenses have the characteristics of high impact resistance, high transparency, and light weight.
It is suitable for long-term wear, and its impact resistance is 250 times that of ordinary glass. It is the choice of many swimming goggle manufacturers.
For lens color, transparent lenses are suitable for use in dim light or indoor swimming pool environments, and can provide a natural field of vision; while dark lenses (such as gray, brown, etc.) are more suitable for outdoor waters with strong sunlight, which can effectively reduce light stimulation and increase contrast.
If you have a high demand for reducing light stimulation, you can also choose swimming goggles with polarized lenses. This type of lens contains small crystals with special structures. These crystals are arranged neatly according to a certain pattern, and only light vibrating in a specific direction is allowed to pass through. It can effectively eliminate reflections from the water surface, reduce glare, filter out messy light, make underwater objects look clearer, improve visual contrast and saturation, and has UV protection.
In addition, there are some photochromic lenses that can automatically adjust the color depth according to the intensity of light, providing convenience for different scenes.
4. Adjustability of goggles strap
The goggles strap needs to have good elasticity and adjustability.
Elastic goggles straps can adapt to different head sizes to ensure that the goggles are worn firmly and comfortably. The adjustable design allows users to adjust the tightness according to their needs to avoid headaches caused by too tight or goggles falling off due to too looseness.
5. Durability
Considering the durability of goggles, you can start with the material quality of the frame and lenses.
Wear-resistant frames and lenses can withstand frequent use and contact friction with water, pool walls, etc. At the same time, the scratch resistance of the lens is also important, which can extend the service life of the goggles.
Wear-resistant goggles frames usually use the following materials:
Thermoplastic elastomer (TPE)
This material has good elasticity and wear resistance. It can withstand the friction with the pool wall and other objects in the swimming pool environment, and it is soft to the touch. It fits the face well when worn without causing discomfort. For example, the frames of some professional sports goggles are not easy to show signs of wear after long-term use.
Polycarbonate (PC)
Polycarbonate material has high hardness and excellent wear resistance. At the same time, it also has good impact resistance and stability, which can keep the goggles frame intact in complex use environments and is not easy to deform or damage. Many high-end goggles brands often use this material to make frames.
6. Brand and price
Choosing goggles from well-known brands is often more guaranteed in quality and after-sales, but the higher the price, the better. You can compare and select cost-effective products from multiple brands according to your budget. At the same time, referring to the evaluation and recommendations of other swimmers can help you make better decisions.
