Every day we are exposed to increasing amounts of blue light. Outdoor exposure to blue light comes from the sun while indoor exposure comes from artificial sources of blue light such as computers, tablets, cell phones, televisions and modern energy-efficient light bulbs. Over time, blue light can impair our daily visual performance, disrupt our ability to sleep and contribute to the development of macular degeneration a devastating eye disease that can lead to vision loss. Constant exposure can impact visual performance by increasing sensitivity to glare, reducing contrast and color perception and decreasing visual acuity. Ask your eye care professional how you can protect yourself and your loved ones from the dangers of blue light exposure.
Here are some of the top computer ergonomics tips recommended by the U.S. Department of Labor’s Occupational Safety & Health Administration (OSHA). These tips are designed to reduce the risk of stress, physical injury and computer eye strain from prolonged computer use.
- Sit so your head and neck are upright and in-line with your torso, not bent down or tilted back.
- Face your computer screen directly. Avoid viewing your screen with your head turned or your back twisted.
- Keep your elbows comfortably close to your body.
- Use a chair that provides support for your lower back and has a cushioned seat with a contoured front edge.
- Keep your mouse close to your keyboard so you don’t have to reach for it.
- Position your computer display so the top of the screen is at or slightly below eye level. This will allow you to view the screen without bending your neck.
- Adjust the position of your display to prevent reflections of overhead and outdoor lighting appearing on your screen.
- Put your monitor close enough to your eyes so you can comfortably read text on the screen without leaning forward.
- When working with print documents, use a document holder that positions them at the same height and distance as your computer screen.
- Use a hands-free headset when talking on the phone while working at your computer.
Also, adjust the height of your chair and desk so that:
- Your upper arms are perpendicular to the floor, not stretched forward or angled backward
- Your forearms, wrists and hands form a 90-degree angle with your upper arms
- Your thighs are parallel to the floor and your lower legs are perpendicular to the floor
- Your wrists and palms are not resting on sharp edges
If you wear bifocals or trifocals, you should be able to comfortably view your computer screen without tilting your head back. If this is not the case, consider purchasing computer glasses.
Following these tips will help you avoid stressful postures that lead to headaches, neck and back pain and computer vision syndrome.
But remember, prolonged computer work ‚Äî even at an ideal workstation ‚Äî is stressful to your body and your eyes.
To relieve stress that can lead to computer vision syndrome and physical disorders, be sure to take frequent breaks when working at a computer.
Many experts, including optometrists who specialize in computer vision, recommend that you get up and move away from your computer for short breaks at least every 20 to 30 minutes.
Take a few minutes to stretch your arms and back, and let your eyes relax their focus by looking at something at least 20 feet away.
Also, blink fully and frequently to reduce your risk of dry eyes from computer use. If necessary, apply “artificial tear” eye drops to moisten and lubricate your eyes.
Where to Buy Computer Glasses

Because an accurate eyeglasses prescription is essential if you want to get the full benefits from computer glasses, it’s best to purchase this eyewear from a knowledgeable eye care professional.
Prior to scheduling your eye exam, measure how far you like to sit from your computer. Measure from the bridge of your nose to the surface of your computer screen.
Bring this measurement with you to your exam so your eye doctor can use it to help determine the optimum lens power for your computer glasses.
