Important!
If you have inadvertently looked at the sun for a short while, you know that its light is so bright and strong that it causes eye pain and temporary loss of vision. That is why you should never look straight into the sun.
Sight is a very important sense. The eyes are extremely sensitive. Focusing your eyes on objects lying close to them is exhausting. When using the computer or reading books, let your eyes rest sometimes: close every hour for a while, intensively blink a few times and look into the distance without looking at the object. Remember also that the sun can not only harm us if we look straight at it. Sunglasses with a high UV filter are very useful (that is, protecting against ultraviolet radiation). These glasses should be worn not only in the summer, but also in winter, because the light reflecting off the snow can damage the eyes!

Sunglasses should have large enough glasses to cover all eyes, not just part of what we see straight

Nowadays there are very common problems with human eyesight: myopiamyopiamyopia, farsightednessfarsightednessfarsightedness and astigmatismastigmatismastigmatism. It may happen that initially the eye defect is not serious, but it increases over time. The eyes get tired when using the computer and watching TV, as well as when reading with too little light. Remember that the room may be dark, but the text you read must be well lit.

Protecting the ears
It is not only the eyes that need to be protected! Another of our senses, hearing, is as equally important and vulnerable. If you live in a city, you hear noise caused by traffic every day. The road works or the taking‑off and landing of planes are even louder. Even some toys can cause hearing damage! We already know that the volume is measured in decibels (dB). The more decibels, the louder the sound, and thus the more dangerous to health.
The type of sound
Sound volume
rustling of leaves in the wind
10 dB
whisper
20 dB
noises in the house
40 dB
playing loud TV
65 dB
busy street, bustling cafe
70 dB
warning! Sounds over 110 dB can permanently damage your hearing!
chainsaw close up
110 dB
jet taking off
130 dB
explosion of firecrackers close up
160 dB
Fortunately, the ears can also be protected. In conditions of high noise (eg when the renovation is in house and the drill is very loud), it is best to use special protective earmuffs. You can also use ear plugs. Try not to listen to music too loud. It is most harmful to listen to it through the earphones.

Summary
Our eyes and ears are exposed to damage even during everyday activities.
To protect against eye damage, we use goggles and allow the eyes to rest during the day. We also do not read when the light is too dim.
To protect against ear damage, we use protective earmuffs and avoid noise.
