Harmful Effects of Blue Light

Protect Yourself from Computer Vision Syndrome

Blue light is a hot topic nowadays due to the fact that we are constantly exposed to its potential health hazards. However, how much do you know about blue light? Our eye doctors have prepared the following outline to explain the basics of blue light – and the reasons you need to protect yourself from it.

Definition of Blue Light

All light is composed of electromagnetic particles that constantly release energy as they travel in waves. These light waves differ in length and strength, and shorter wavelengths emit higher amounts of energy. Wavelengths are referred to by color, with blue light having one of the shortest (highest energy) wavelengths on the spectrum of visible light.

Where Are You Exposed to Blue Light?

Exposure to blue light happens everywhere! The sun’s rays include natural blue light, and modern technology emits large quantity of artificial blue light. Fluorescent lighting, LED lights, digital screens and all electronic devices release blue light into our atmosphere. Nowadays, people spend hours per day using computers and digital tech, which puts our eyes and bodies in nonstop contact with blue light.

Hazards of Blue Light

In reality, moderate amounts of the sun’s natural blue light can benefit your health. It helps to regulate your circadian rhythm, which is responsible for your sleeping and waking times. Blue light can also put you in a better mood, give you energy and bolster your memory. However, overexposure to blue light, both natural and artificial, can lead to a list of health problems.

Computer Vision Syndrome and Digital Eyestrain

Blue wavelengths flicker, which causes a glare that puts extra stress on your visual system. Over time, viewing a digital screen can therefore lead to many uncomfortable symptoms. It doesn’t matter if you’re staring at a computer screen, tablet, smartphone or other gadget, all of these electronic devices can cause Computer Vision Syndrome (CVS). In contemporary society, estimates claim that the average person spends at least 6 hours per day in front of some type of digital display. It’s no wonder why our North Carolina eye care specialists diagnose Computer Vision Syndrome so frequently in our clinics in Raleigh, Durham, Fayetteville, Burlington, Wilmington and Cary, NC.

Symptoms of Computer Vision

The classic signs of computer vision include:

  • Blurred vision
  • Dry eyes
  • Trouble focusing between near and far
  • Constant need to blink or rub your eyes
  • Headaches
  • Eyestrain
  • Neck, shoulder and back pain

While computer vision and blue light can cause the above symptoms, these complaints may also be caused by other factors, such as glare, poor lighting, uncorrected vision needs and improper posture.

Healthy eyes have melanin, which acts as a natural filter against normal exposure to hazardous blue light. However, melanin doesn’t protect enough against overexposure, which is the problem in our high-tech world. Additionally, melanin decreases with age. Recent studies show that the massive doses of blue light shining into our eyes are leading to an increased rate of macular degeneration and retinal damage. These ocular diseases threaten your lasting, quality vision.

Blue light is also associated with:

  • Increased risk of diabetes, obesity and heart disease
  • Higher prevalence of certain cancers
  • Increased chances of depression
  • Disruption of circadian rhythm, which can cause insomnia and sleep disorders

Stay Safe from the Dangers of Blue Light

Computer glasses are an effective way to block blue light from reaching your eyes. Wearing computer glasses can reduce your risks of developing the symptoms of computer vision and help preserve your eye health. Customized lens tints, coatings and lens powers can enhance your vision and comfort!

For more info, ask our eye doctors about computer glasses in our optometry offices in Raleigh, Durham, Fayetteville, Burlington, Wilmington and Cary, NC. We can help optimize the health of your eyes and body with protection from blue light!
