Blue light, or high energy visible light, is an increasingly present phenomenon in our everyday lives that poses a serious threat to the health of our eyes. If you live in the United States in the 21st century, statistics show that you are likely to be spending up to 25 hours every single week staring at the screen of your computer, tablet, smart phone or television. That is more than the total of an entire day, without sleeping, in front of devices that emit harmful blue light.
Recent studies indicate that this level of blue light exposure is linked to an increase in a person's risk of macular degeneration as they age. At special risk for this are those who have a history of macular degeneration in the family, and children, due to their larger pupils and shorter arms, relative to adults, which cause them to hold electronic devices closer to their faces.
Fortunately, our eyes have a natural defense against blue light called macular pigment. This is a yellow spot in the eye that acts as a sort of internal sunglasses, and is found in the area of the retina responsible for central and detail vision, known as the macula.
Dr. Dan Bristol of Bristol Family Eyecare in Austin, Texas explains, “The amount of a person's macular pigment can vary, and may be influenced by a person's diet. A great deal of research has been done on the impact of the amount of macular pigment on the prevention of macular degeneration and promotion of overall visual health. Much of this research indicates that a low amount of macular pigment is a key risk factor for macular degeneration, while a high amount of macular pigment seems not only to reduce one’s risk for macular degeneration, but may also help to improve visual performance.”
So, what can you do to be sure that your amount of macular pigment remains as high as possible to protect your long term eye health and maintain your optimal vision?
Two of the major substances that constitute macular pigment are lutein and zeaxanthin. Unfortunately, the body does not make lutein and zeaxanthin itself, so taking it in as part of one's diet is essential. “Research shows that a diet rich in zeaxanthin can increase a person's macular pigment and promote healthy vision.” explains Dr. Bristol, “However, the common U.S. diet is deficient in these essential substances, making the taking of proper vision supplements, such as EyePromise Restore , essential for long term vision health. EyePromise Restore is a unique vision supplement, made from dietary lutein and zeaxanthin, rather than the more common synthetic meso-zeaxanthin. This guarantees a higher rate of absorption into the body, meaning much better results in promoting a high amount of ocular pigment and protecting your eyes from the harmful effects of blue light.”
