Why do pilots have to wear sunglasses when flying?

To ensure perfect vision, pilots must wear special sunglasses when flying .

Pilots often have to wear sunglasses when flying , but it's not just to look cooler. Many people would think that wearing sunglasses could interfere with identifying all the lights, buttons and instructions on the plane. But the truth is not like that.

The important thing for a pilot is to have good health and perfect eyesight. They need annual check-ups and make sure they don't have any vision problems. Daily eye care is required to maintain perfect vision, but this is not always easy for pilots.

The harmful radiation the Sun emits is trapped by the Earth's atmosphere, so sunlight is unlikely to cause harm if you spend most of your time above ground. But in the sky there is less air and the brightness is 5% higher every 100ft (30.5m). The average plane flies at an altitude of 35,000ft (10,700m), which means the amount of UV radiation is 1,750% higher than on the ground.

This is very harmful to eyesight, making pilots susceptible to eye diseases. Encountering such problems can cost pilots their careers. That's why they wear sunglasses to protect their eyesight.

Pilot sunglasses must also be of the best quality . They must minimize the impact of sunlight and protect the eyes 100%. In addition, they must not be polarized because polarization may interfere with viewing of cockpit displays. These glasses must completely reduce eye strain and even minimize color distortion so that the pilot can see just like without glasses.
