How Blue Light Affects Your Eyes and How to Protect Them
Blue light is a group of light that the sun and screens such as mobile phones, computers, and televisions produce. These days, human beings spend a lot of time on such devices. That is why we receive the blue light in the eye more frequently.
What Happens When Blue Light Enters Your Eyes?
When you stare at the screens, blue light passes through the eyes and enters the back area, known as the retina. Your eyes might be fatigued and become dry in case you watch screens for too long.
Effects of Blue Light on Eyes
If you spend too much time in front of these sources, such as computers or TV, eye strain may occur. Your eyes feel sore, dry, or like they want to shut. Those who experience long periods of screen time might get a headache or their vision might get blurry. Blue light at night can also keep you awake because it tricks your body into thinking it is time to stay awake.
Signs of Eye Strain from Blue Light
- Eyes feel dry or water a lot
- Hard to keep eyes open
- Eyes get tired quickly
- Headaches or discomfort around the forehead
- Blurry or double vision
If you notice these signs often, blue light could be the reason.
Who is Affected Most?
Nowadays, children, adults, and even elderly people are found to spend numerous hours on the screen. Individuals with work or video-watching exposure to more than two hours a day are at a higher risk when experiencing the blue light fading effects. Eye strain due to blue light can also affect those who practice healthy eating.
How to Protect Your Eyes from Blue Light
- 1. Follow the 20-20-20 Rule
Every 20 minutes, look away from your screen. Focus on something 20 feet away for 20 seconds. This helps your eyes rest.
- 2. Adjust Your Screen Settings
Reduce screen brightness. Try “night mode” or “blue light filter” on your device to make the light softer for your eyes.
- 3. Blink More Often
Blinking maintains the moisture of your eyes; however, people blink much less when viewing display screens. Don’t forget to blink more, try and remember that.
- 4. Eat Healthy Foods for Eyes
Fruits and vegetables, for example, oranges, carrots, and green leafed vegetables, help in keeping one’s own eyes healthy.
- 5. Use Blue Light-Blocking Glasses
Blue light may also cause eye strain, and special glasses may help to reduce the amount of strain in the eyes, particularly when using computers over long periods of time.
- 6. Keep Screens at the Right Distance
Hold your mobile and tablet at least an arm’s length away. Keep your computer monitor a little farther away for less stress.
- 7. Limit Screen Time Before Bed
Avoid looking at screens one hour before bedtime. This aids your body in preparing to rest and sleep better.
Benefits of Good Eye Care
In following such simple steps, your eyes will not be tired anymore, fewer headaches will occur, and sleep will be enhanced. Healthy foods provide an additional shield to your eyes. You are happier and live life better.

- Pick outdoor games over phones or tablets
