What is blue light?
Blue light is a part of the visible light spectrum that’s not only present in sunlight, but in the light that comes from your digital devices, including your MacBook. Although blue light helps to keep us alert, it also has a number of unwelcome side effects.

Why is blue light so harmful?
Blue light penetrates our eyes, telling our brains that it’s time to wake up and get on with our day. So far, so good. Unfortunately though, prolonged exposure to blue light can cause a range of issues, from eye strain and headaches, to fatigue and a lack of focus.

Most notable is its inhibition of melatonin, a chemical that influences our sleep-wake cycle and helps us to drift off at night. By disrupting this cycle, blue light exposure can cause us to feel lethargic, irritable and unproductive. You might be understandably pumped to get your hands on the latest MacBook, but yikes!

How do I reduce the blue light from my MacBook?
Fortunately though, Ocushield’s blue light filters for MacBook Air and Pro block blue light before it gets to your eyes. This helps to keep them in tip-top condition, reducing dryness and facilitating focus.

Created by qualified optometrists, our FDA registered anti-blue light filters block up to 99% of damaging UV and blue light emissions between 300-400nm, and as much as 54% of harmful blue light between 400-470nm.

What’s more, by limiting your exposure to blue light before bed, Ocushield’s blue light filter for MacBooks will help you catch ZZZs and enjoy all the benefits of a good night’s kip.
