Why Do You Need Blue Light Blocking Glasses? More Direct Eye Protection While Maintaining a Stylish Look, Instead of Just Consuming Lutein!
What Exactly Is Blue Light, and Why Do We Often Hear About the Need to Protect Against It?
Modern lifestyles are heavily intertwined with smartphones and computers. We spend long hours staring at screens, not only for work but also after work and even before bedtime. We often hold onto our phones, only realizing the need for a break when our eyes become dry, fatigued, or even watery, or when we experience high eye pressure. In the natural world, there are various sources of light, divided into visible and invisible light, all of which have different effects on our eyes. Infrared and ultraviolet light, which we often hear about, are examples of invisible light. Today, I'd like to delve into one type of visible light - blue light.
The Impact of Blue Light: A Force to Be Reckoned With, Affecting Vision and Sleep.
Blue light is not just a component of sunlight; it's also present in modern artificial light sources such as LCD displays, smartphone screens, and LED lights. Unlike ultraviolet radiation, blue light penetrates the eye, and prolonged exposure can lead to eye fatigue and blurred vision. Furthermore, blue light affects the body's circadian rhythm and the production of melatonin, which can disrupt sleep. This is why we often hear about the need to protect against blue light.
A Little Eye Care Knowledge: Blue Light with Shorter Wavelength Requires More Protection
Blue light has higher energy and a shorter wavelength, typically ranging between 400-500 nanometers. It has stronger penetration capabilities compared to red and green light. Reports indicate that blue light with wavelengths between 415-455 nanometers can penetrate the eye's crystalline lens and reach the retina, potentially leading to cataracts and macular degeneration. Some types of blue light may even cause atrophy of retinal pigment epithelial cells, contributing to myopia. Given modern lifestyle habits, protecting your eyes and slowing down the progression of myopia through blue light protection is a crucial step that shouldn't be delayed.
Why is Wearing Blue Light Blocking Glasses So Important?
Effective blue light blocking glasses feature special lens coatings that help shield your eyes from harmful blue light. They can reduce eye fatigue caused by digital devices, prevent disruptions to your circadian rhythm, and subsequently improve sleep quality and overall health. Blue light, with its shorter wavelength, tends to scatter more, requiring your eyes to work harder to focus and leading to muscle tension. Prolonged exposure to blue light can trigger photo-toxic reactions in pigment molecules within your visual cells, causing cell damage. Over time, this can lead to glare, fatigue, dry eyes, and pseudo-myopia.
It's essential to strike a balance with blue light blocking, as overly high blocking percentages can reduce visible light transmission and impact visual acuity. A 30% blue light blocking rate represents an optimal balance, providing the best user experience.
Blue Light Blocking Glasses with Stylish Designs
Rosie Allan's blue light blocking glasses series uses polycarbonate (PC) lenses, originally developed for astronaut visors and bulletproof glass. These lenses possess exceptional impact resistance and can withstand military-grade impact tests, remaining intact upon impact. They also exhibit excellent dimensional stability, heat resistance, lightweight properties, and up to 90% transparency. With no need for special UV coating, they offer 100% UV protection.
Through professional SGS testing, these glasses effectively block blue light, reducing direct exposure to high-energy harmful blue light. They minimize the blurriness caused by glare from illuminated screens and alleviate eye fatigue. Additionally, they help reduce dryness and discomfort caused by blue light exposure, maintaining eye moisture. These glasses enhance colour contrast and clarity, making reading more comfortable. Designed for Asian facial features, they come in various stylish styles, combining fashion and a flattering fit. You'll feel the difference as soon as you put them on – a must-check item!
