What’s the Deal with Blue Light? Smartphone Light Damaging to Retina at Night

If you lie in bed or sit in the dark and play with your cell phone or other electronic devices, you could be damaging your eyes. Not only will using digital devices in bed cause a disruption in your sleep cycle, but the blue light that emanates from these devices has been linked to a variety of health problems.

Smartphone Light Damaging to Retina at NightThe blue light coming off of these devices is a part of the full light spectrum, so everyone is exposed to it during the day when out in the sunlight. However, when you are exposed to it at night, in the dark, at the high levels that are emitted from cell phones, computers, tablets, and other devices with LED screens, it can cause problems to your eyes and vision.

Problems Caused by Blue Light

When your eyes are directly exposed to blue light, it can cause the retina to become damaged. According to the American Macular Degeneration Foundation, damage to the retina caused by blue light can result in the development of macular degeneration. Macular degeneration causes loss of central vision and when that happens, you will no longer have the ability to see things in front of you.

It also disrupts your sleep cycle because it limits the production of melatonin in your brain, which is a hormone that is responsible for your moods, emotions, and regulating your sleep patterns. If you’ve had trouble sleeping well at night, it might be a good idea to skip taking anything to bed with you that produces blue light and see if your sleep doesn’t improve.

When melatonin production is thrown off, it can cause all sorts of things to go wrong in your body and your brain and can even lead to an increased risk of health issues such as depression and cancer. While blue light has always been around – in the sun and in other devices – the real problem comes from continual usage at close range to your eyes in low-light or dark settings.

Overexposure to blue light can also cause eye strain and vision problems, such as dry eye and blurred vision. Because digital technology has become such a big part of life over the last several years, more and more people are showing up at their optometrists’ offices complaining about blurred vision, strained eyes, burning sensations in the eyes, and a whole slew of other problems. And because this has become such a big issue, there is even a name for this condition now – Computer Vision Syndrome.

People who wear corrective lenses may be even more affected by blue light than those who don’t wear glasses or contacts and this is due to the fact that regular corrective lenses are not designed for reading or doing other sorts of activities on computers, tablets, or cell phones.

It’s recommended that people who wear corrective lenses and are experiencing eye strain and other issues after using digital devices should purchase a pair of computer glasses or occupation glasses. These types of glasses are designed specifically for use with computers and will do a better job of protecting your eyes from the damaging effects of extended computer use.

Steps to Take to Reduce Eye Damage

If you want to protect your eyes from damage, there are many things you can do. For starters, limit or completely eliminate the use of smartphones, iPads, computers, and even the TV at night when you’re in bed or even when you’re sitting in a dark room. This alone will help to reduce your risk of developing macular degeneration as well as other eye and vision problems, and it will allow you to get a good night’s sleep.

Limiting your use of these devices that emit blue light during the day is also a good idea. You may cringe at the thought of being without your smartphone for any length of time, but there was a time when there was no such thing as a smartphone and everyone survived just fine without having one glued to their hand all day. If you want to save your eyesight and decrease your chances of vision loss one day in the future, it will be worth it to spend a few hours of the day without your smartphone, computer or any other type of digital device.

If your job requires you to use the computer for long periods of time, be sure to take frequent breaks to give your eyes a rest and consider purchasing a pair of computer glasses as mentioned earlier. You may also want to make sure there is sufficient light in the room and that there are no glares from windows or lighting on your screen as these issues can also cause problems with your vision.

Get regular eye exams. This is probably the most important step you can take to ensuring your eyes stay healthy. Some vision problems are symptomless and can only be detected through a thorough eye exam, so if you’re getting regular eye exams, you can be assured that any problems will be detected early enough for treatments to begin.

The last thing you might want to consider is incorporating easy eye vitamins into your daily diet. If you have vision problems such as farsightedness, nearsightedness, or astigmatism, eye vitamins can help to improve those issues and reduce the strain that is put on your eyes.


About Orlin Sorensen

My vision started to get blurry as a young teenager. Soon I was wearing glasses for just about everything. This was a hard blow for me because I had always dreamed of becoming a U.S. Navy fighter pilot which required perfect vision without glasses or surgery. But I wasn't ready to give up on my dreams, so I looked into every possible alternative which led me to eye exercises. Through daily vision training and eye exercises, I improved my vision from 20/85 to 20/20 and passed the Navy's visual acuity test. In fact Men's Health declared this one of the "Greatest Comebacks of All Time!" Now, I'm sharing exactly how I did it with the program that helped me so people like you can improve your vision safely and naturally, without glasses, contacts or laser surgery.

    i also know about the blue light from the digital devices affects our eyesight recently. Lately i have to use computer a lot because of different assignments and feeling my eyes very dry. I think I probably also the computer vision syndrome as it is mentioned in this blog. My friend suggested me to wear a pair of computer glasses and told me that it can protect my eyes from ‘blue light’. It is also surprising to know that my eyes will be more affected by ‘blue light’ if I wear corrective lenses to work in front of computer or to read on my smartphone
