Should You Use Minus Swimming Goggles When Swimming?

Swimming may feel a little difficult for people who have minus eyes. The reason is, even people with healthy and normal vision will look blurry when in water. So, do you really need to use minus swimming goggles while swimming?

Use minus swimming goggles, do you really need it?

In normal eyes, the incoming light must fall right into the eyepiece and cornea so that the image can be focused on the retina. Normal-eyed people can see clearly when on land because light is not blocked or disturbed by any element around it.

Now when in the water, even a normal view will blur because the optical layer of the cornea of ​​the eye and water has almost the same level of turbidity. This causes light refraction to not occur, so that vision will blur when you accidentally open your eyes under water.

For those of you who have a minus eye, refraction of light on the land is not right from the start. The incoming light actually falls in front of the retina of the eye so you cannot see objects that are far away clearly. This vision problem can be corrected using minus glasses.

So just like when you wear regular glasses to see everything on the ground clearly, you need to use minus swimming goggles if you want to swim. The principle is similar. Your eyes work well for processing images if light enters the eye without obstruction from the air.

When you use minus swimming goggles, you have a "barrier" in the form of air between the cornea and glasses. So even if the light comes from underwater, the light will first pass through the air between your glasses first and then reach the eyes. So, your vision will look exactly like when you are on the ground and can see better.

In addition to helping you see more clearly, wearing swimming goggles protects your eyes from the risk of irritation from exposure to chlorine which can make red eyes.

Isn't it better to use contact lenses and swimming goggles only?

No. Many people choose to use minus contact lenses and then use regular swimming goggles while swimming, although this is not recommended by the Foods and Drugs Administration (FDA), the drug and food regulatory agency in America.

When pool water enters the glasses, the residue can stick to the contact layer of your lens so that bacteria and germs from the water can infect your eyes.

If you are someone who has minus eyes and quite often swims, it never hurts to invest in good quality minus swimming goggles. Swimming goggles are now being sold in a variety of designs and features as needed, including swimming goggles with a minus lens.

Tips for choosing good minus swimming goggles

In general, minus swimming goggles are equipped with ready-made circular lenses (diopters) that are the same as reading glasses that can be found in optical stores. Ideally, you should also get a recipe with the same value as your regular glasses. But usually, the minus swimming goggles score may not be as exact as those in reading glasses or contact lenses.

So when shopping for swimming goggles, make sure you tell the condition of your eyes and what the value of your glasses minus the shop clerk to find swimming goggles with a range of minus scores that are closest. Many minus swimming goggles are sold with lenses from -1.5 to -10.0 and have multiples of 0.5.

After getting swimming goggles with the right minus lens, you also need to understand the correct size and how to use them. Glasses that are too loose or incorrectly installed will make water flow into the lens space. This not only interferes with your vision, it also risks causing irritation.

Look for eyewear designs that are suitable for the type and shape of your face. Swimming goggles with narrow nose pieces are usually intended for children and adolescents to help maintain the shape and position of swimming goggles in stable and immovable eyes.

Then, examine the color of the lens and search for what is needed. The lenses of swimming goggles that are a little dark are suitable for use when swimming during the day to protect your eyes from excessive sunlight.

Finally, swimming goggles offer three types of ropes. There are single straps, double straps, or separate single straps according to your needs and comfort when wearing them.
