Shedding Some Light on Blue Light

It’s hard to know something’s a threat to your health when you’re not even aware it exists. That’s the general consensus when it comes to blue light. I’ve prepared a short guide to what it is, what it does, and how you can reduce its effect on your eye health.

What is blue light?

Blue light is a high-energy light ray on the visible light spectrum. It’s emitted naturally by the sun, but other sources include fluorescent and LED lighting, televisions, and digital device screens on phones, tablets, laptops and computers.

How is it harmful?

When blue light hits the eye, it goes deep, reaching all the way to the retina. Extended exposure – i.e. more than two hours each day – to blue light can permanently damage retinal cells, which don’t reproduce. Blue light is especially harmful for children, as their developing eyes absorb more blue light than adults.


So, how does one avoid the inevitable?

Because blue light is literally everywhere, you need to protect yourself. Here’s what you can try:

Blue-Light Blocking Glasses

Brands like Felix Gray and Warby Parker offer blue-light filtering lenses so you don’t have to worry about your retinas during the long work days.

Supplements with lutein and zeaxanthin

Lutein and zeaxanthin are a must for filtering out blue light. The yellow color of these carotenoids enables them to absorb blue light right up. Make sure you’re getting the recommended 20 mg of lutein and 4 mg of zeaxanthin to make an impact, though, with our Ocuguard Blutein line of supplements.

The 20-20-20 Rule

Every 20 minutes, look away from your computer at something 20 feet away for 20 seconds. This doctor-recommended tactic helps reduce eye strain brought on by digital device screens, also known as Computer Vision Syndrome.


In conclusion

Blue light is hard to avoid. It can noticeably affect you daily while also leaving a long-term impact on your eye health.
