How Blue Light Affects Your Body, Aging, and Toxin Exposure

Post by: KATHY SKINNER in blue light
In today’s digital world, we are constantly surrounded by screens—whether it’s our smartphones, computers, or even energy-efficient lighting. These modern conveniences expose us to more blue light than ever before, and while technology has made life easier in many ways, the effects of blue light on our bodies, especially as we age, can be harmful.

What is Blue Light?
Blue light is a type of high-energy visible (HEV) light that has a short wavelength and high frequency. It’s naturally present in sunlight and helps regulate our circadian rhythm—our body’s natural sleep-wake cycle. However, artificial sources like screens, LED lights, and fluorescent lighting expose us to blue light far beyond what our ancestors experienced. And this excess exposure comes with consequences.
 

While blue light has some benefits, like boosting alertness during the day, long-term overexposure can accelerate aging. Here’s how:
 
It can cause Skin Damage: Blue light penetrates the skin more deeply than UV rays, contributing to oxidative stress. This leads to collagen breakdown and premature aging of the skin, manifesting as wrinkles, fine lines, and hyperpigmentation.
 
Eye Strain and Vision Issues are accelerated: As we age, our eyes naturally lose some of their ability to block out blue light. Excess exposure can cause digital eye strain, fatigue, and even damage to the retina, which may lead to age-related macular degeneration.
 
It Disrupts Your Sleep Patterns: Blue light exposure, especially in the evening, suppresses melatonin production—the hormone responsible for regulating sleep. Poor sleep has been linked to faster aging, weakened immune function, and increased oxidative stress, all of which can make you feel and look older.
 
Constant exposure to blue light also increases oxidative stress in the body. Oxidative stress occurs when there’s an imbalance between free radicals (unstable molecules) and antioxidants. This imbalance accelerates cellular damage and aging. It also makes your body less effective at detoxifying itself, which means harmful toxins can build up faster.
 
Blue light exposure has also been linked to increased cortisol levels—the body’s stress hormone. Chronic stress from elevated cortisol can lead to inflammation and toxin buildup, which further accelerates aging and can cause various health issues.

 
Blue-light limiting glasses, also known as blue-light blocking glasses, have become a popular solution to combat the harmful effects of blue light. 
Here’s why they’re worth considering, especially if you're concerned about aging and overall health:
 
They help reduce the amount of blue light that reaches your eyes, which may reduce the overall amount of blue light exposure your body experiences, lessening oxidative stress over time.
 
They help improve Sleep Quality: Wearing blue-light limiting glasses in the evening or while working late can help maintain melatonin production, ensuring better sleep quality and improved cellular recovery.
 
They help reduce Eye Strain: Blue-light limiting glasses are designed to filter out a significant portion of HEV light, reducing digital eye strain, headaches, and discomfort.
 
 You may be wondering if Blue-Light Glasses block out 100% of Blue Light.
The answer is No. Typically, blue-light glasses block a certain percentage, often ranging from 20% to 90% of blue light, depending on the brand and the specific lenses used.
 
Here’s the breakdown:
- Lower percentage (20-50%): Many blue-light glasses designed for daytime use block a moderate amount of blue light to reduce eye strain and improve comfort during prolonged screen time.
  
- Higher percentage (60-90%): Glasses intended for evening or nighttime use often block more blue light to help prevent disruptions to sleep and melatonin production.
 
- 100% blocking: These are specialized glasses, usually with a more noticeable amber or orange tint, claim to block 100% of blue light, but they may alter color perception significantly, making them less practical for regular daytime use.

I have found that my 100% Blue Light Blocking glasses from EyeKeeper,  that I wear in the evening have only a slight alteration of color perception. I have also noticed that I have less eye strain going to bed as well. It might be from these or maybe it is from a combination of their blue light blocking glasses I wear when I am on the computer. 
They offer Perscription, Readers & no magnification glasses of all styles to suit your needs. Check them out with this LINK to also get 20% off!


Blue light is everywhere, and while it’s a necessary part of life, overexposure can lead to harmful effects on your body, accelerating the aging process and increasing toxin buildup. Taking preventive measures, such as wearing blue-light limiting glasses, can make a significant difference in your long-term health and vitality. 

Small lifestyle changes like this can help you age more gracefully and keep your body functioning optimally.

Let me know if you have tried Blue Light Limiting Glasses.
