A blue-light-blocking lens is an excellent way to protect your eyes against the blue and violet light produced by digital devices. These lights cause damage to the retina, which can result in vision impairment. As the blue and violet wavelengths have higher energy levels, they are difficult for your eyes to process. But with the proper use of blue-light-blocking lenses, you can reduce their effects and improve your vision.
Filtering Out High-Energy Violet And Blue Light
Wearing a pair of blue light blocking glasses can improve your eyesight in various ways. They reduce eye strain and help you focus better. In addition, they can reduce the risks of macular degeneration and cataracts. Whether you work long hours or spend a lot of time on your computer, wearing these glasses can help you stay healthy.
Blue light is electromagnetic radiation, which is dangerous to your eyes. Too much exposure to this type of light can cause skin cancer. It also affects color perception. It is, therefore, essential to avoid prolonged exposure to bright light. Exposure to sunlight may also lead to skin cancer.
A particular brand’s transmission and blocking percentages are essential for choosing the right blue light-blocking glasses. You want your glasses to block fewer than 70% of blue light. You can test this by looking at an online color test or a transmittance spectrum report. To test the effectiveness of a particular type of blue light-blocking glasses, try to search for an image of a rainbow. The blue part of the rainbow should look black, while the rest should appear darker.
Reducing Digital Eyestrain Symptoms
Studies have shown that wearing blue light-blocking glasses can reduce symptoms of digital eyestrain. In particular, they can reduce redness and dry eye. In addition, the glasses can reduce eye itchiness. Other measures may help you avoid digital eyestrain, such as taking frequent breaks from the screen and using eye drops.
One common cause of digital eyestrain is not blinking frequently enough. Studies show that people who suffer from this condition reduce their blink rate by 50 percent. So, it’s essential to practice regular blinking. Another way to minimize digital eyestrain is to reduce the brightness of your screen. You can do this by using anti-glare screens or by purchasing low-wattage bulbs. You can also prevent glare by avoiding areas of extreme brightness.
Blue light-blocking glasses help reduce eye strain by limiting the amount of blue light reaching the eyes. There is no direct evidence that blue light causes headaches, although light often triggers this condition. But by limiting the light that reaches the eyes, these glasses can significantly reduce eye strain.
To ensure you’re wearing the best glasses, you should check for UV protection and blue-light-blocking properties. Also, look for glasses that don’t squeeze your nose or slide down your face. A pair should also not be tight behind the ears. If you’re unsure about blue light-blocking glasses, you can start with an inexpensive pair and see how they fit.
Several studies show that wearing blue-light-blocking glasses can help reduce the amount of blue light that enters the eyes. These studies have also shown that they can reduce the amount of redness and eye itching. Consequently, blue-light-blocking glasses are an excellent option for those who spend hours in front of a computer.
Not Harmful For Your Eyes
Despite what you may have heard, blue light-blocking glasses aren’t necessarily harmful or destructive for your eyes. It is recommended to follow the 20-20-20 rule:
- Take a 20-second break after every 20 minutes of screen time.
- Ensure your prescription is correct and you maintain good posture when using a screen.
- Avoid looking at a screen two to three hours before sleep.
The amount of blue light you’re exposed to depends on several factors, including time of day and season. If you’re outdoors all day, your exposure to blue light is likely lower than in the office. However, even cloudy days can expose you to blue light. Wearing sunglasses may help reduce your exposure to blue light. Electronic devices automatically adjust to bright light, so blue-blocking glasses are designed to counteract that.
Some studies suggest that blue-light-blocking glasses help reduce eyestrain and other symptoms caused by computer use. These symptoms include eye fatigue, redness, and headaches. Additionally, these glasses are supposed to reduce computer vision syndrome symptoms. However, it needs to be clarified if they help.
