Protect the eyes from the dangerous blue light

HERE’S a look at how students can prevent eye problems when working on a tablet or laptop.

In the short term, blue light is tiring for eyes, causing eye strain, and also drying eyes out. In the long term, it increases the risks of age-related macular degeneration (ARMD).

As well as affecting eye health, blue light is known to suppress the secretion of melatonin – a hormone associated with sleep onset – levels of which usually rise in the body from around 9pm. It may, therefore, disrupt sleep.

Lack of sleep could, in turn, potentially contribute to a drop in performances at school.

However, initial feedback from primary schools and middle schools equipped with tablets appears to show boosted motivation and improved collaboration among students.

Cut out blue light To protect children from blue light, look for applications or device settings that cut out the blue light mode in smartphones and computers. Also, try increasing font size onscreen.

Some glasses can now provide lenses with built-in blue light filtering for children under 16.

Give eyes a break To reduce eye fatigue and dryness, it’s recommended to look away from the screen regularly for a few seconds at something far away that doesn’t emit blue light. Also keep blinking often to rehydrate eyes.

Spend more time outside To make up for time spent in front of screens, outdoor activities should be stepped up to ensure exposure to natural light. – AFP-Relaxnews
