We’re all guilty of checking our phones a little too often at times aren’t we? Aside from using them to actually speak to people, we now use them for checking our social media accounts, our email, reading the news, shopping, listening to music and even telling the time. It’s safe to say that our smart phones have become indispensable. In fact, under 25s are said to check their phones at least 32 times a day. But aside from being anti-social, it’s not really that much of a problem is it?
Well actually it might be. You see, those sharp displays of light and colour are made up of blue light, and this can be toxic to our eyes.
We need a certain amount of ‘good’ blue light to regulate our body clocks, but exposure to the wrong types of blue light over a long period of time – checking your phone frequently each day, for example – can cause damage to the back of the eye. Over exposure can even lead to macular degeneration, which can eventually lead to blindness.
And eye damage isn’t the only negative effect of overusing your smart phone. You may also suffer with eye strain from looking too closely or for too long at your screen, headaches, and even stress if you can’t check your phone as often as you’d like to (sad, but true!).
Don’t think that by switching your phone for your tablet will help either. Tablets, computer screens, and even your flat screen TV will contribute to your blue light exposure, so it’s really important to limit your use of these things where possible.
Often it’s difficult to escape blue light exposure; especially if you work in an office and use a computer all day long. However, you should speak to your optician to find out about various types of lenses that can be used to filter out blue light.
At Eye Emporium, we recommend a range of specs, sunglasses and optical aids that filter out blue light, which is especially important in a your sunglasses. Pop in to see us if you would like some advice.
If you’re worried that you may have caused damage to your eyes, either from over-exposure to blue light, or from anything else, book in an eye exam to make sure everything is as it should be. You might be surprised at how much state-of-the-art eye examinations can detect these days.
