Swimming goggles are indispensable for every swimmer. Although it is quite simple to buy swimming goggles right now, to choose suitable goggles you need to keep in mind some of the following issues.
A swimming goggles no matter how polished and “genuine” it will be useless if it doesn’t fit you. The fitting glass is when the goggles cup must match the eye socket, the size of the glass fits your head and most importantly: a glass that fits well to absolute water leakage.
Usually, the edge of the swimming goggles is designed to include a soft rubber gasket. When wearing and lightly pressing the glass, the gasket will push the air out of the glass out and suck it tightly around your eye socket, thereby preventing water from entering the glass. A glass would fit well when the size of the rubber gasket was not too large nor too tight compared to the eye sockets, but the sucking was not too loose nor too tight.
Your swimming goggles can be very good at water spills, but if it causes discomfort or even pain when used for long periods of time, it’s best to consider replacing another pair of glasses. Unfortunately, to know if a pair of swimming goggles is comfortable, there is no other way to try and use it for a long enough time.
Swimming goggles do not provide a comfortable feeling when it causes tension, too deep sores, even redness in the sensitive skin around the eyes, temporal area, head area. To limit these problems, ask the seller what kind of glass is made of good material, with fringe and glass of soft rubber or silicon.
This criterion relates only to the lens part of the swimming goggles.
Most swimming goggles are now made of scratch-resistant, anti-frog, and UV-resistant (anti-UV). If a glasses does not have all these functions, you should not buy them if you are really serious about swimming.
