With World Sleep Day on March 14th, Optical Express is raising awareness about an often overlooked factor that could be affecting your eyesight: sleep. It turns out that the quality and duration of your sleep may play a more significant role in your eye health than you might think.
Millions of people unknowingly put their eye health at risk simply by not getting the right amount of rest. According to leading eye health specialists at Optical Express, both sleep deprivation and excessive sleep can have negative impacts on vision, and understanding the ideal amount of rest is key to maintaining healthy eyes.
The Vital Connection Between Sleep and Eye Health
Sleep is essential not only for our overall health but also for the proper functioning of our eyes. During sleep, the eyes go through a recovery process that includes producing essential tears and removing irritants and toxins that build up throughout the day. When sleep is disrupted, either by not getting enough, or in the other direction by oversleeping, the eyes can suffer from a variety of issues, some of which can lead to long-term vision problems.
The Dangers of Too Little Sleep
Most people are familiar with the common effects of sleep deprivation, such as fatigue and irritability, but many might not realise that insufficient sleep can have serious consequences for your eyes. The experts at Optical Express warn that chronic sleep deprivation can lead to several eye issues, including:
- Dry Eye Syndrome: Lack of sleep reduces tear production, leaving the eyes dry, irritated, and uncomfortable.
- Blurred Vision: Fatigue from sleep deprivation can make it difficult to focus, causing vision to become blurry or even double.
- Eye Spasms: Myokymia, or twitching eyelids, is a common side effect of not getting enough rest.
- Increased Risk of Eye Diseases: Chronic sleep deprivation has been linked to an increased risk of conditions like glaucoma, which, if left untreated, can result in permanent vision loss. Glaucoma is often referred to as the “silent killer” of vision due to its subtle symptoms.
The Dangers of Too Much Sleep
While we all know that too little sleep can be harmful, it may surprise you that oversleeping can also have negative consequences for your eyes. Experts at Optical Express point out that sleeping for more than nine hours a night can contribute to certain eye health risks, including:
- Increased Eye Pressure: Prolonged sleep may be linked to raised intraocular pressure, which is a major risk factor for glaucoma.
- Circulation Issues: Oversleeping can affect blood flow to the eyes, potentially leading to retinal problems over time.
The Ideal Amount of Sleep for Eye Health
So, what’s the magic number when it comes to sleep? It’s recommended that adults aim for seven to nine hours of sleep each night for optimal eye health. This range allows your eyes to rest, repair, and stay hydrated, reducing the risk of developing common eye problems.
Stephen Hannan, Clinical Services Director at Optical Express, emphasises the importance of quality sleep, saying, “Many people don’t realise just how vital sleep is for eye health. The eyes go through a natural recovery process while we sleep, and without adequate rest, they can become dry, irritated, and more susceptible to disease. Getting between seven and nine hours of good quality sleep each night is one of the easiest and most effective ways for the vast majority of the public to protect their vision in the long term.”
