Most of the individuals have heard that they should reduce their exposure to blue light. Exposure to digital screens may affect the blue light, that is emitted from such as laptops, flat-screen television, tablets, and smartphones. The reality is that it could be lead to permanent damage to your eyes. And the risk of blue light damage from screens is higher because of the proximity to the screens and the time you spent on them. If you’d like to find out more about blue light, then read this full article inspired by Vista Clear Reviews to find what it is and how it could impact your eyes.
What is Blue Light?
Blue light is the visible light spectrum and it is a short wavelength, high energy frequency of light. Sunlight is the main source of blue light, as it is made up of red, orange, yellow, green, blue, indigo, and violet light. When it’s combined, it becomes the white light we see. Blue light is associated with damage to the retina and may also be associated with digital eye strain. Moreover, it is essential to good health and maintaining a healthy circadian rhythm. Mostly the Blue light is emitted by electronic devices such as fluorescent lights, LED TVs, computer screens, smartphones, and tablets.
Sources of Blue Light
The sun is the major source of blue light. Some of the potential sources of blue light include:
- Fluorescent light tubes.
- Compact Fluorescent Light (CFL) bulbs.
- LED bulbs.
- LED TVs and screens.
- Computer monitors.
How Does Blue Light Affect the Eyes?
Almost all visible blue light passes through the cornea and lens and reaches the retina, and the direct penetration of crystals into the retina causes irreversible retinal damage. Some research and studies have found that too much exposure to blue light could cause eye problems. This is because the molecule called rhodopsin in our eyes helps us see, especially in low-light situations. It has a complicated structure that includes attachments to another molecule called retinal. So when the blue lights hit the retinal, it causes the whole molecule to twist a tiny bit and cause a chain reaction that damages the walls of the cells in the eye.
Blue light may contribute to digital eye strain because it scatters more easily than other wavelengths, it’s not as easy to focus. So when you’re looking at a computer, a cell phone, or another blue light-emitting device, this unfocused light reduces contrast and makes your eyes work harder.
Some studies have found that too much exposure to blue light could lead to:
Long exposure to blue light causes worsening of visual fatigue and nearsightedness. Major symptoms of Myopia are diplopia and inability to concentrate which can affect people’s learning and working efficiency.
- Cataract formation.
The blue light exerts its protective effect on the retina, and when it affects the lens undergoes a decrease in transparency that leads to cataract formation.
Blue light from digital devices can lead to eyestrain. The major symptoms of eyestrain include sore or irritated eyes and difficulty focusing.
- Retina damage.
Continued exposure to blue light may lead to damaged retinal cells. And this may cause vision problems such as age-related macular degeneration.
Protecting Yourself From Blue Light
Constant exposure to blue light is an issue, so here are some best ways to decrease exposure to blue light:
- Limit the amount of time spent in front of a screen or take frequent breaks to give your eyes a rest.
- Use screen filters, decrease the amount of blue light given off from these devices that could reach the retina in our eyes.
- Use yellow-tinted computer glasses, as they can block blue light and ease computer digital eye strain by increasing contrast.
- Use gadgets in the night mode.
- Keep the brightness at 50% while using laptops.
- Use anti-reflective lenses, it reduces glare and increases contrast, and also blocks blue light from the sun and digital devices.
Surprising Benefits of Blue Light
- It boosts alertness.
- Helps memory and cognitive function and elevates mood.
- It regulates circadian rhythm.
- Exposure to blue light during the daytime helps to maintain a healthful circadian rhythm.
- Decreased exposure to sunlight is important for children, or else it could affect the growth and development of the eyes and vision.
5 Quick Steps You Can Take Right Now to Protect Your Eyes
- Look for a Computer Equipped with a Built-in Blue Light Filter.
- Proper Lighting in the Room to reduce possible glare, as well as reflections.
- Adjust Display Brightness to maintain the screen slightly brighter than the ambient lighting.
- Adjust Contrast for superior comfort and utilize the night mode when available.
- Adjust Color Temperature with more red and less blue.
