Computer Eye Strain

People who have advanced eye disease have waited too long to improve their vision health. Keeping the eyes health is a lifetime endeavor. An unhealthy lifestyle and poor nutrition lead to a higher risk of eye diseases. Researchers have linked cataracts, macular degeneration, glaucoma, optic neuropathy, retinal vein occlusions, and other eye conditions to mostly-controllable risk factors. Seniors are especially at risk. Natural Eye Care offers this guide to improving vision health.

A strong study in the International Journal of Ophthalmology found that omega-3 fatty acids significantly reduced dry eyes. Dry eye syndrome is becoming more prevalent in the West from extended close-up work on computers and phone screens. The condition can also be caused by an autoimmune disorder; it can accompany menopause; and it can have other causes. Symptoms include burning, dryness, irritation, a feeling of grit, and difficulty reading for extended periods.

Omega-3 fatty acids are found in highest quantity in

Americans are spending at least 5 hours per day close-up looking at computers, tablets and smartphones.¹ However, our eyes were not designed for extended hours of close-up work. In the same way that we need regular physical exercises, we also need eye exercises. We evolved as hunter-gathers, and our eyes are made to scan the landscape. Modern technology has resulted in wide-spread computer eye strain. Symptoms include short-term dry eyes, worsening farsightedness, nearsightedness and astigmatism, eye focusing disorders and poor eye coordination.

Chinese scientists have identified nutrients that come from marine algae that may prove to provide even better support for vision health problems due to computer eye syndrome than the antioxidants lutein and zeaxanthin. Fucoxanthin¹ comes from a brown seaweed where it is the primary part of the light-absorbing mechanism of the plant.  It is what gives seaweed a brown or olive-green color.

Blue light is emitted from all handheld electronic devices as well as desktop and laptop computers and televisions. It is the shortest wave length light in the visible spectrum and causes significant damage to many parts of the eye seriously impacting present and future vision capacity. Damage from blue light from smartphones is particularly important because smartphones are often used in dim light and are used close to the eyes. Unlike ordinary computer vision fatigue, damage from blue light is serious, cumulative and irreversible.

Eye strain is the symptom that most people associate with overuse of electronic visual display devices — from television to laptops & desktops — to smartphones — to handheld games and ebooks.

Smartphone ownership has grown explosively with 68% of Americans owning smartphones in 2015 compared to 35% in 2011. Most adults under age 50 (79%-85%) are smartphone owners, and of the middle-age to senior group (age 50-64) more than half own and use smartphones. This growth has lead to increased rates of a number of vision conditions.

Electronics have become primary obsessions in our personal and work lives. This has lead to nearly everyone becoming susceptible to Computer Vision Syndrome. Symptoms include dry eyes, eye strain, blurred vision, headaches, double vision, difficulty in concentrating, fatigue and/or and head, neck and shoulder pain.

Additionally, heavy computer use has been associated with glaucoma¹ Electronics screens emit blue light that can damage the retina, leading to macular degeneration.² Close-up work is associated with myopia (nearsightedness).³

How Prevalent Is Computer Eye Syndrome?

Vision is the sense most heavily relied on by modern, technological society. Hearing may come in as a close second, but even without a sense of hearing, we could still navigate most electronics. Without our eyes, that becomes a laborious task. But what, exactly, are the screens we look at so much, doing to our eyes?

Blue Light Damages the Retina

Those glowing flat panes, held mere inches from our face, emit a powerful light that can, opticians say, lead to permanent eye damage. Much of the light that comes out of a screen is blue-violet. Studies show that, over time, too much exposure to blue-violet light can injure the retina. Retina damage can lead to macular degeneration,

Excessive time spent in front of a computer, smartphone, or tablet screen can increase risk of macular degeneration, especially in young people.

The AOA’s survey focused on how much time parents thought their children spent on handheld devices. Their responses easily underestimated those of the children, aged 10 to 17, who reported (83%) that they use a handheld device for at least three hours a day, with 32 percent looking at a screen for more than an hour without glancing
