With the vast amount of technology used, from smart phones, to tablets, to computers, there is a huge concern over our daily exposure to HEV (High Energy Visible) light or blue light. Extended exposure can lead to headaches, blurred vision, red, burning or aching eyes, and other symptoms of Computer Vision Syndrome. It can also lead to Macular Degeneration and other serious eye conditions. But what can you do about it? Resting your eyes by taking a break from your computer or other electronic device is one way of preventing Computer Vision Syndrome. Another potential solution would be to get fitted for Computer Glasses. But what are Computer Glasses and how do they help?
We are all familiar with sunlight, and many of us are aware that sunlight consists of a variety of colours, both visible and invisible to the human eye. Each of these colours represents a different energy wavelength. Most of us should be familiar with the effects of Ultraviolet (UV) rays on our skin. If you have made the mistake of looking directly into the sun, or even snow on a sunny day, you will also be aware of what UV radiation can do to your eyes. But there is another light that is becoming almost as much of a concern, and that is Blue Light.
This week is Sun Awareness Week. Over the last few years the sun has been the subject of some pretty confusing mixed reviews: Sunlight is good for you – No! It’s bad for you. You need to get out in the sunshine – You need to protect yourself from the sun’s rays. So which is the truth? Well, actually both. Sunlight is necessary for good overall health in all living things. It warms the air and helps plants to grow, and it provides a major source of Vitamin D needed for good health in humans. But like many good things, too much of a good thing can have a negative effect. Just as too much sunshine can dry out and kill plant life, overexposure to the sun’s rays can burn and damage our skin, and also our eyes. But how does this happen?
March is National Nutrition Month, a very good time to discuss the effect of diet on your vision. The average rabbit can tell you about the importance of carrots for your eyesight, but what other foods can help?
Aging and Eye Disease
We all know that as we get older, our bodies wear down and need more maintenance and upkeep. The same is true for our eyes. Some common eye diseases that are related to getting older are: Cataracts, Diabetic Retinopathy, Dry Eye Syndrome, Glaucoma, and Macular Degeneration. Many of these age related conditions can be avoided or controlled by maintaining a healthy lifestyle, not smoking, getting regular exercise, and eating healthy. But what is a good diet to maintain eye health?
With so many screens to stare at: computers, tablets, iPads, Smart Phones; and so much work being done electronically, people are left with one big question. Is all this time staring at a computer screen harming my eyes? The simple answer is, it can if you aren’t careful.
Computer Vision Syndrome
There are two names that are used interchangeably to describe the same eye condition, which results from excessive computer use. These are Computer Vision Syndrome and Digital Eye Strain. The symptoms are dry, irritated eyes, headaches, blurred vision, red eyes, often accompanied by neck and shoulder strain and back pain.
Perhaps you’ve heard the term “blue light”, but aren’t sure if it affects you or not. There are definitely some misconceptions about blue light, where it’s found and the potentially harmful effects, so hopefully this post can help to shed some ‘light’ on the situation.
Where is blue light found?
Blue light is everywhere. Smartphones and other digital devices have been targeted as the main blue light culprits, but the truth is, sunlight is the main source of blue light. Being outdoors during daylight is where most of us get the majority of our blue light exposure. There are also many man-made, indoor sources of blue light, such as fluorescent and LED lighting and flat-screen televisions.
