Binge-watching Netflix? Working crazy hours at night? Restless night’s sleep? Out socialising until late? We all know how important it is to get some shut-eye to feel refreshed the next day (most adults need an average of 7-9 hours of sleep each night) and how bad sleep deprivation is for our health. When we get enough sleep, we have a stronger immune system, our blood pressure stays healthy, and we feel happy and energetic! Let’s find out how lack of sleep can adversely affect our eyes and what we can do to keep them healthy.

Rest your eyes

Just as your body needs to recover and rest, so too do your eyes. People who don’t get enough sleep regularly are at the risk of developing dry eyes, eye strain and twitchy eyes. It’s not that surprising – after all, the eyes are a set of sensory organs and a part of our central nervous system. That’s why poor bedtime habits are just as bad for your eyes as it is for your overall health.

Stop screen time before bedtime  

Tossing and turning instead of going to sleep? Stay away from your smartphone – it could cause insomnia. Checking your phone keeps your brain stimulated and engaged instead of relaxed. The blue light emanating from your digital device mimics daylight and this restricts the production of melatonin, the hormone that regulates your sleep-awake cycle (circadian rhythm). This makes it harder for you to fall asleep. Our optometrists advise you to stop using all screens at least one hour (two hours for children) before bedtime. In fact, keep your phone out of your bedroom and invest in an old-fashioned alarm clock.

Avoid wearing contact lenses overnight

If you wear contact lenses, make sure to take them off before going to sleep. Having contacts in your eyes during bedtime prevents the flow of oxygen to your eyes, and increases the risk of getting an eye infection.

So, make sure to get enough sleep, practise good eye hygiene and visit our optometrists regularly to ensure that your eyes are healthy.
