Is it OK to swim without goggles?

In the gym, swimming can be said to be a sport that everyone likes very much. Especially in summer, most young people go to some swimming pools to learn how to swim. Generally speaking, we need to prepare a lot of equipment when swimming. Among them, swimming goggles are an indispensable one. But many friends will find it troublesome. So, is it okay to swim without goggles?

1. Why do you need to wear glasses when swimming?

(1) The lenses of the goggles are parallel, which ensures clear vision both above and below the water, without causing visual distortion.

(2) When swimming, you will inevitably be exposed to ultraviolet rays. Wearing glasses can prevent ultraviolet rays from entering your eyes, avoid eye damage, and improve your underwater vision!

(3) Since the refractive index of the water surface is different from that of the air, if you do not wear goggles, things will appear blurry, affecting your swimming efficiency!

(4) Since water is in direct contact with the air and there are many people in public swimming pools, there are relatively many bacteria. Therefore, wearing glasses when swimming can prevent bacterial infection and avoid some eye diseases!

(5) If you are a myopic patient, wearing myopic swimming goggles while swimming can not only provide you with clear vision underwater, but also help correct your vision, allowing you to fully experience the freedom and ease of swimming!

2. The dangers of not wearing swimming goggles

If you don't wear goggles in the swimming pool, you will be exposed to many substances that are harmful to your eyes. Public swimming pools usually contain disinfectants and bleach. Even if these things are directly discharged into the tap water without being treated, there are still certain bacteria, so they will have a certain impact on people's eyes!

If you swim in a river, the composition of the water cannot be analyzed, so it is relatively unsafe. Also, if you are often exposed to the sun, ultraviolet rays can cause great damage to your eyes. Therefore, if your eyes are exposed to pure water for too long, it will cause discomfort to your eyes. The harm is even greater in water containing disinfectants. Therefore, you must wear goggles when swimming. This is a must!

3. What are the complications of eye injuries?

If you do not protect your eyes well when swimming, it is very easy to get conjunctivitis, which is mainly caused by viruses, bacteria and allergic reactions. Summer itself is a season when viruses and microorganisms grow and spread rapidly. It is also a season when various acute conjunctivitis are prevalent. Public swimming pools are very likely to cause the spread of conjunctivitis.
