One things that can reduce eyesight is due to exposure to light radiation for too long. For that, if you work too often using a laptop / computer, or staring too long at the smartphone screen, it can reduce eye health.

Preventive things that are very important to do to maintain eye health include:

If the eyes feel tired when staring at a computer / smartphone screen, immediately rest your eyes so that the eye muscles become relaxed again
If the eyes are too often staring at objects at close range in detail, then it must always be balanced by looking at objects remotely so that the eye muscles do not have difficulty focusing to see long distances. The tips are to stop for a moment from seeing close up every 20 minutes, replace it with seeing the focus distance (about 20 meters or more) for 20 seconds
Stop smoking, because smoking can increase the risk of cataracts, damage to the optic nerve, and macular degeneration
Avoid seeing blinding lights. If necessary, use anti-radiation goggles to protect the eyes from sun exposure because UV rays can increase the risk of cataracts and macular degeneration
