What Are Blue-Light-Blocking Glasses and How Do They Work?
In today’s digital world, we spend hours in front of screens, whether it's for work, entertainment, or socializing. But with all that screen time comes a downside: blue light exposure. This type of light is emitted from digital screens and can cause eye strain and affect your sleep. But don’t worry—Phifinery Eyewear has the perfect solution with our blue-light-blocking glasses.
What Is Blue Light?
Blue light is a high-energy visible (HEV) light in the shorter wavelength range of the visible light spectrum, specifically between 400 nm to 450 nm. It is a portion of the light that is emitted by digital screens such as phones, computers, and TVs. Prolonged exposure to blue light can lead to eye discomfort, especially during long screen sessions, and disrupt your sleep cycle by interfering with your circadian rhythm.
What Are Blue-Light-Blocking Glasses?
Blue-light-blocking glasses, also known as screen glasses or computer glasses, are designed to filter out the high-energy visible light (blue light) that digital screens emit. They protect your eyes by preventing this light from reaching your eyes, helping to reduce digital eye strain and improve sleep quality.
How Do Blue-Light-Blocking Lenses Work?
Blue-light-blocking lenses come with special coatings or tints that either reflect or absorb blue light.
- Reflective coatings typically have a bluish hue and block around 10% of blue light.
- Absorbing lenses, usually with a yellow or amber tint, block 35% or more of blue light. Some lenses even block up to 98% of blue light, but these lenses can change the colors you see, making everything appear reddish-brown, like a sepia-toned photo.
Phifinery Eyewear offers blue-light-blocking glasses with lightly amber-tinted lenses that filter up to 50% of blue light emitted from digital screens (420 to 450 nm). These lenses provide minimal color distortion, allowing you to use your devices without sacrificing color clarity.
How Do Blue-Light-Blocking Glasses Protect Your Eyes?
By filtering out blue light, these glasses can help reduce eye strain caused by prolonged screen time. Additionally, they can improve your sleep quality by protecting your circadian rhythm. Blue light exposure, especially before bedtime, suppresses melatonin, the hormone that signals your body to sleep. Using Phifinery Eyewear blue-light-blocking glasses before bed can help you fall asleep more easily by filtering blue light and letting your biological clock recognize when it's time to wind down.
Do Blue-Light-Blocking Glasses Actually Work?
The effectiveness of blue-light-blocking glasses is a subject of debate among researchers. Some studies show that blue light contributes to digital eye strain, while others argue it doesn’t have a significant impact. However, research published in The Journal of Clinical Endocrinology and Metabolism highlights that blue light does affect melatonin production, which can interfere with your sleep cycle.
While opinions vary on the degree to which blue light impacts eye strain, many users report subjective improvements in eye comfort and sleep quality when using blue-light-blocking glasses. For those who spend long hours in front of digital screens, trying Phifinery Eyewear blue-light-blocking glasses may be the perfect way to enhance both comfort and rest.
