Understanding the Basics
When it comes to protecting your eyes from harmful blue light, two popular options are Blue Light Blocking AR (BlueShield) and Blue-Violet Light AR (Crizal Prevencia). Both technologies aim to reduce the exposure to blue light, which is emitted by digital devices, LED lighting, and the sun. However, they do so in slightly different ways, offering unique benefits and considerations.
Blue Light Blocking AR (BlueShield)
Blue Light Blocking AR, commonly known as BlueShield, is designed to filter out blue light from digital devices and LED lighting. This technology is particularly beneficial for those who spend long hours in front of screens, as it helps reduce eye strain and fatigue. BlueShield lenses are made with a special coating that absorbs blue light, preventing it from reaching the eyes.
One of the key advantages of BlueShield is its versatility. These lenses can be applied to a wide range of eyewear, including prescription glasses, sunglasses, and even contact lenses. This makes it a convenient option for those who already wear glasses or need additional protection from blue light.
Blue-Violet Light AR (Crizal Prevencia)
Blue-Violet Light AR, known as Crizal Prevencia, focuses on blocking blue-violet light, which is considered more harmful than blue light. This type of light has a shorter wavelength and higher energy, making it more likely to cause damage to the eyes. Crizal Prevencia lenses are designed to filter out this harmful light, providing enhanced protection for your eyes.
Crizal Prevencia lenses are particularly beneficial for those who spend a significant amount of time outdoors, as blue-violet light is more intense in sunlight. These lenses offer a higher level of protection against harmful UV rays and blue-violet light, making them an excellent choice for outdoor enthusiasts and those who work in bright environments.
