Eye Health


| 2 Comments
When using my computer or phone for too long, or staring at the screen in the dark, I often find my eyes beginning to hurt. And of course, my mom always told me not to sit too close to the TV screen. This is normal, I'm sure, and happens to many people, but does this problem have a lasting impact on our eyes? Apparently not.

News Medical describes that although staring at a bright screen for too long may cause some problems, it does not effect your eyes permanently. Several problems that are caused by this habit are eye discomfort, headaches, itchy, dry, or watery eyes, and difficulty focusing. One of the most prevalent occurrences is eyestrain. This is often caused by glare, which is usually due to a screen being either too dark or too bright. Because of this, eye muscles strain to focus on what is on the screen and must try to make out the images. Another cause is the positioning of such a screen. If it is anywhere above eye level, the eyes struggle to stare and must keep working to look in the direction, rather than straight ahead where they normally are.

According to WebMD, 50- 90% of people suffer from a disease called Computer Vision Syndrome, or CVS. Simply stated, it is caused by repetitive motion, aka staring at your computer screen for too long, far too often. This problem is often much easier to get when a person already suffers from something else, such as nearsightedness or astigmatism.

So, although the problem is not really permanent, there is a definite risk when using a phone or computer, or staring at TV for too long. Always rest your eyes or take breaks when possible in order to help keep your eyes safe!

This topic is really interesting. I feel like there might be a lot more business for eye doctors because of the extreme amount of technology that is constantly in our faces. I feel like as college students, we are especially vulnerable to being exposed to CVS. This article, http://wearesocial.net/blog/2010/08/uks-media-consumption-habits/, points out media consumption by age group. It is apparent that people 18-24 years old barely use print media, and spend the most amount of time on the computer. I wonder what remedies we can use for CVS?

This topic is great news, especially in this day and age. We constantly use our laptops and we're super close to the screen which obviously causes problems for our eyes. I have bad eyesight as it is and when I heard that it might make them worse I panicked! I can't have worse eyes than I already do! So knowing that it doesn't cause permanent damage is awesome. When I spend too much time doing homework on my laptop my eyes do start to get painful and that's when I know that it's time to take a break!
