How to Beat Blue Light with These 5 Superfoods

If you remember your school science lessons, you’ll probably already know that light comes in a spectrum. That’s why, when you refract light through a prism, it separates into different shades. What you may not remember from school is the fact that blue light is especially harmful to your eyes, especially over the long term.

How to Beat Blue Light with These 5 Superfoods

Unlike red light at the other end of the light spectrum, blue light is composed of shorter wavelengths with a higher frequency. This means that the light vibrates with more energy, which is potentially more harmful to our eyes.

It’s Everywhere!

Generated by the sun, smartphones, computer screens, TVs and artificial lighting, blue light is everywhere – and it’s pretty much inescapable. But it’s not all doom and gloom. Fortunately, our eyes have an inbuilt system to protect us from the vibrations of blue light. Known as the macula, this “system” has a yellow pigment which filters out blue light, helping to keep our eyesight safe.

Degeneration Stations

Unfortunately, this system isn’t foolproof. Macular degeneration is a common condition, often triggered by long-term exposure to blue light. In its early stages, the effects of macular degeneration are almost invisible, but as the condition progressively worsens it can cause serious impairment in your vision – and even blindness.

It’s more Common than you Think…

A whopping one in ten people over the age of 65 are affected by age-related macular degeneration, while three in ten people over the age of 75 are also affected by the condition. But is macular degeneration an inevitable part of aging? Or are there steps we can take to look after the health of our eyes and our macula?

Is there a Cure?

A fresh study from Harvard University believes there is a solution to age-related macula degeneration. The answer, they claim, is to consume more of certain fruits and vegetables – and no, we’re not talking about eating carrots to help you “see in the dark”.

Instead, the researchers recommend that we all incorporate more lutein and zeaxanthin into our diets.  Found in especially high quantities in leafy greens and well-known superfoods, these crucial macula-protecting ingredients have been shown to reduce the chance of developing the condition by 40%. The detailed survey followed the lifestyles and ocular health of 102,046 individuals over the course of 20 years, giving the results serious credence.

  1. My grand daughter was just complaining of her eyes burning and I wonder if it’s because she’s been playing on her Kindle and cell phone. Thank you so much for the list and tips, I’m going to try them for all of us.

  2. I am DEFINITELY going to have to add more of these super foods to my diet! I stare at a computer screen all day long and I really need to be more on top of my eye health!

  3. I certainly need to eat more of these. I was at the eye doctor not long ago, and I was reading about blue light. I get migraines often, and I’m always on the computer. I’m sure that’s what’s causing a lot of them for me.

  4. This is a great post! I need to eat more kale and peas. I enjoy both of those foods a few times a week, but now I will try it a bit more often.
