How Sleep Affects Eye Health

According to research, sleep deprivation resembles alcohol in how it impacts your mind, body, and eye health…

While that’s not good, how do our eyes fit into the equation? Why is our eye health dependent on sleep and how can we can improve our sleep quality by changing what we put in front of our eyes before bed? Well here’s a few things that you might want to take into consideration if you are feeling sleep deprived. 

The Effects of Sleep Deprivation on Eye Health

If you aren’t getting enough sleep, you may find yourself grumpy, drowsy, and having trouble concentrating. Not to mention those things also leading to weak immunity, weight gain, increased blood pressure, and mood changes which are all signs of sleep deprivation.  Sleep deprivation can also affect our eyes. 

To function effectively throughout the day, our eyes need at least five hours of sleep each night. The need for sleep extends beyond simply keeping our eyes open throughout the day. We are more likely to experience eye strain, dry eyes, and even twitching when we don’t get enough sleep. The good news is that our eyes play a role in getting more and better sleep that will help them!

The blue light that comes from screens and our internal clocks

Our eyes are biologically incapable of being altered, no matter how tech-savvy we are. Over the course of all of human history, blue light has only ever come from the sun, until recent years that is. Blue light tells our brain it’s daytime, so we should be awake. We trick our brains into thinking it’s not yet bedtime by looking at screens late into the evening. Therefore it is always a good idea to power down devices long before bedtime. 

Before you go to sleep, turn off the blue light

If you are having trouble going to bed there may be a few factors contributing to your inability to fall asleep. Late-night screen use maybe one of the things not helping you sleep once you’re in bed if you don’t feel tired until very late at night once you’re in bed. If you are going to be using a computer or a screen after sundown, we recommend either putting them away at least an hour before bed or switching to a screen setting that reduces the blue light. The quality of your sleep and the health of your eyes will improve significantly if you do this!

Put your contact lenses away for the night

Modern contact lenses are much more oxygen-permeable than they used to be (allowing your eyes to breathe easier) but if you plan to wear them overnight, you should still take them out. Wearing your contact lenses overnight can be uncomfortable not to mention it may also lead to infection.

Sleeping with your eyes free of contact lenses will reduce your risk of eye infection and help them to recover from their day’s work. You can keep your contacts in if you wish, as long as you follow the directions on the packaging and take them out as often as you need to.
