In today's digital age, electronic devices have become an integral part of our lives. From smartphones and tablets to laptops and monitors, we spend more and more time in front of screens. However, this overuse can have negative consequences for our eye health. One of the most common problems associated with prolonged use of electronic devices is eye fatigue, also known as computer vision syndrome.

Causes of eye fatigue:

- Blue light: Electronic devices emit high-energy blue light that can penetrate deep into the eye and cause eye fatigue. Continued exposure to this light can disrupt the circadian rhythm and affect the quality of sleep.

- Reduced blinking: When we are in front of a screen, we tend to blink less frequently than normal. Blinking is essential to keep the eyes lubricated and protected. Lack of adequate blinking can lead to dry eyes and fatigue.

- Distance and viewing angle: Most people hold electronic devices at a closer distance and at an angle that is unnatural for vision. This can increase strain on the eye muscles and contribute to fatigue.

Symptoms of eye fatigue:

- Eye dryness and redness: one of the most common symptoms is the feeling of dryness and the appearance of redness in the eyes. This is due to lack of blinking and reduced tear production.

- Eye fatigue and eye pain: Eye fatigue can manifest as a feeling of tiredness or heaviness in the eyes. It may also be accompanied by eye pain, sensitivity to light and burning sensation.

- Blurred vision: after long hours of using electronic devices, it is possible to experience blurred vision or difficulty focusing on objects at different distances.

Prevention tips:

- Take regular breaks: it is important to take frequent breaks while using electronic devices. The "20-20-20" rule can be very helpful: every 20 minutes look at an object 20 feet away for at least 20 seconds.

- Blink more frequently: remember to blink regularly to keep your eyes lubricated. You can do this consciously or use apps or reminders to help you maintain a proper blinking rhythm.

- Adjust the lighting and contrast: make sure the screen of your electronic devices is not too bright. Adjust the lighting and contrast settings to suit your environment and reduce eye fatigue.

- Use blue light filters: consider using blue light filters on your electronic devices. These filters help reduce the amount of blue light emitted and can alleviate eye fatigue.

- Maintain an appropriate distance: place electronic devices at an appropriate distance and at a level slightly below the line of sight. This reduces eye strain and associated fatigue.
