Lighting Tips to Avoid Eye Strain
Avoid Harsh Lighting
According to the American Optometric Association, more than half of office workers who use computers daily have eye strain. The lighting in your room or workspace plays a major role in your comfort while using digital devices. Many offices have extremely bright or harsh interior lighting that can trigger eye strain. Experts suggest using fewer light bulbs and fluorescent tubes.
Glare can make it difficult for you to see what’s on the screen and also cause discomfort. It can occur if there is a window directly in front or behind you. A simple way to prevent glare on your screen is to move your table, close the curtains or blinds, or add an anti-reflecting coating on your glasses.
Adjust the Brightness of Your Screen
Computer screens emit blue light, which can also contribute to eye strain. One way to help your eyes feel more comfortable while working is to adjust the brightness of your screen so it’s nearly as bright as your surroundings.
Avoid Reading in the Dark or Dim Light
Good lighting is even more essential if you are doing tasks that require intense focus. While reading or using devices in the dark won’t permanently damage your eyes, they can give you headaches. You can reduce your risk of developing eye strain by using task lighting around your home, such as desk lamps, under-cabinet lighting, and reading lamps.
Good Light Can Help People With Low Vision
The older you get, the more your need for good lighting increases. According to research, a 60-year-old needs nearly twice as much light as a 30-year-old. Individuals with macular degeneration, glaucoma, and other eye conditions should talk to an eye specialist regarding specific improvements they can do to their lighting to enhance their home’s visibility.
What Are the Best Kinds of Light for Your Eyes?The best type of light for good eye health is warm light sources, such as natural light. Many modern windows can allow natural light while blocking the harmful ultraviolet rays from the sun. These windows will flood your home with natural light throughout the day, which is beneficial to your eyes.
Some of the most common artificial warm light sources you can get are incandescent bulbs and LED bulbs. These kinds of light are not only better for your eyes but are also more energy-efficient. Another thing you can do is to get full-spectrum bulbs for your light fixtures. These bulbs resemble the sun’s warm natural lighting but without the harmful effects of UV rays.
Which Kinds of Light Should You Avoid?
One of the worst kinds of light you can expose your eyes to is UV. Its main sources are fluorescent tube lighting and the sun. Over time, exposure to UV light can lead to cataracts and permanent vision loss. When going outside, make sure you are wearing UV-blocking sunglasses to keep your eyes protected.
Blue light is another kind of light that can possibly harm your eyes. This form of cool light generates a significant amount of energy. It usually comes from your tablet, television, computer, and smartphone screens. You can avoid excessive exposure to this light by wearing protective eyewear while using your computer. Your local eye clinic may be offering eyeglasses with an anti-blue light coating.
