Do You Need To Wear Prescription Swimming Goggles When Swimming?

Swimming may be a little difficult for people with minus eyes. The reason is, even people with healthy and normal eyesight will appear blurry when in the water. So, do you need to wear prescription swim goggles while swimming?

In a normal eye, the incoming light must fall right on the lens of the eye and the cornea for the image to be focused on by the retina. People with normal eyes can see clearly when on land because the light is not obstructed or disturbed by any elements around them.

Now when in the water, even a normal view will be blurred because the optic layer of the cornea of ​​the eye and water has almost the same level of turbidity. This prevents light refraction from occurring, resulting in blurry vision when you accidentally open your eyes underwater.

For those of you who have minus eyes, the refraction of eye light on land is not right from the start. The light that comes in falls in front of the retina of your eye, so you can't see objects that are far away clearly. This vision problem can be corrected using prescription swimming goggles.

So just like when you wear ordinary glasses to see everything on land clearly, you need to wear prescription swimming goggles if you want to swim. The principle is similar. Your eyes work best for processing images when light enters them without obstruction from the air.

When you wear goggles for minus eyes, you have a "barrier" in the form of air between the cornea and the goggles. So even if the light comes from underwater, it will first pass through the air between your goggles first and then reach your 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 chlorine exposure which can make your eyes red.

Many people choose to wear minus contact lenses and then wear regular swimming goggles while swimming even though this is not recommended by the Foods and Drugs Administration (FDA), the food and drug regulatory agency in America.

When pool water gets into the glasses, the residue can stick to the lining of your contact lenses so that bacteria and germs from the water can enter your eyes.
