How to find the best swim goggles
Swimming goggles provide essential eye protection, whether you're swimming in salt water, fresh water or in a public or private pool. Worn to keep salt, chlorine and other contaminants and irritants out of the eyes, swim goggles also help you see clearly when you're underwater.
The best swim goggles are airtight, forming a seal around your eyes that no water can get past. Lenses are usually made from plastics and range in thickness. Wider-gauge plastic swim goggle lenses are more durable but can cause some vision distortions, while thinner-gauge lenses maintain regular visual perception but don't have the same impact resistance.
Swimming Goggles: Available Options
Many swimmers grow frustrated with the tendency of swim goggles to fog up relatively quickly after underwater immersion. To combat this problem, you have two choices. The first option is to treat your swimming goggles with a fog-preventing spray, which is available at many sports retail stores. Alternately, you can buy anti-fog swim goggles with specially crafted lenses designed to resist the effects of condensation.
Like sunglasses, swim goggles can also offer UV protection. Swimming goggles are available will a full range of lens tints and colors, and in general, you should choose darker shades for bright conditions and select lighter or clear lenses when you need to make the most of a small amount of available light.
Both adults' and kids' swim goggles can be fitted with prescription lenses if you or your kids rely on glasses to see properly. They cost quite a bit more than regular goggles, though, so you may also want to invest in prescription swimming goggles that have scratch-resistant lenses.
As with any product where the right fit matters, you should try your swim goggles on before you buy them. Some retailers even go as far as to provide customers with a tank or bucket of water they can use to ensure the goggles remain airtight when immersed. Also, keep the type of swimming you plan to do under close consideration: standard swimming goggles can't resist much water pressure, which increases the deeper you go, so if you're doing some deeper diving, make sure you get a pair of goggles that are designed to withstand the added pressure.
Also, keep comfort in mind. Swimming goggles that are too tight will put a lot of pressure on your face and may be difficult to wear for extended periods of time. You can also get swim goggles with dual head straps which alleviates some of the pressure created by single-strap designs.
