How to Size Swim Goggles

If you’re unsure how to size swim goggles, there are several things you should look for. Adjustable nose pieces and double or split straps are common features, while anti-fog coating is also essential. Check the instructions that came with your swim goggles and follow them carefully to get the best fit. Read on to learn more. Also, consider whether you need to buy new ones every few months.

Adjustable nose bridge

An adjustable nose bridge for swimming goggles is a component of the swimming gear that allows a user to customize the fit. The nose bridge consists of an elongated flexible tube that receives two fasteners in a movable manner. These fasteners are positioned so that they pinch securely and provide extra space away from the user’s face. The nose bridge can be adjusted by hand by adjusting the distance between the frames.

The nose bridge of a swimming goggle may need to be adjusted to achieve a tighter seal around the eyes. A nose bridge that falls right away is unlikely to achieve a good seal and will most likely cause irritation during long swimming sessions. If the nose bridge is not adjustable, you may need to buy a different type of swimming goggle. But it is a standard feature of most advanced swimming goggles.


If you’re looking to buy a new pair of swim goggles, you need to ensure that the size is right for you. Double-strapped goggles come in a variety of sizes. Some goggles have an adjustable nose piece, while others do not. The nose piece should fit snugly but not painfully. If the goggles are tight on the eyes, they’ll hurt even more after a swim workout. To ensure that your goggles fit properly, you should check the manufacturer’s return policy.

There are two main styles of double-strapped goggles. The first is the traditional “squeeze-button” strap. This strap type is easier to adjust, and the buckle holds the goggles in place. This style costs more, though, and you’ll find fewer designs for the straps. However, it’s worth the extra money. The straps can also be adjusted in order to fit the head of a person who’s a bit larger or smaller than usual.

Split straps

Swim goggles come with two straps, called double or split straps. While these are convenient, not all straps are the same. Split straps with one large split tend to stay on better than those with two holes. Split straps with two holes usually create a single strap that spans the back of the head and are easier to put on and take off. The double or split straps with squeeze-button bungee type closures are also easier to adjust.

Split straps on swim goggles allow swimmers to adjust their goggle’s fit and release it quickly. These straps come in various styles and designs, and you can choose from four different nose pieces. Most swim goggles also have an anti-fog feature that reduces fogging and provides better vision. Split straps are a great way to prevent fogging and improve your swimming experience.

Anti-fog coating

Almost all swimming goggles are made with an anti-fog coating. These are composed of components that absorb water and either spread it across the lens or repel it. These features reduce the buildup of large water droplets on the lenses and make it easier to see. If your swim goggles do not have this coating, you will quickly notice that they fog up. This problem can be avoided by keeping the lenses clean.

To keep your swim goggles fog-free, take good care of them. Do not use soap or other abrasive products on them before using them. Do not store your goggles in the shower, either. This can scratch the protective anti-fog coating. Instead, dry them completely with an air-drying method. When storing them, you should consider investing in a protective case.

Lens strength

Choosing a swim goggle with the right lens strength is crucial to your overall vision. To find out what your lens strength should be, you can look at the numbers on the sphere and cylinder. The sphere number is the negative four and the cylinder number is the positive one. To calculate lens strength, add these two numbers together, and you’ll have the exact measurement of your goggles’ lenses.

A good fit is essential to prevent water from leaking inside the goggle, and a good pair of goggles will fit well. If your eyes are not the same size, the lenses should overlap the frame of the goggle on the left and right sides. If you have moderate astigmatism, add a few millimeters to the lens strength to avoid fogging. Always rinse your goggles after each swim. Never touch or wipe the inside of the lenses, as this will destroy the anti-fog coating. Let them air dry naturally before putting them back on.
