What is Blue Light and Why Is It Potentially Harmful?
Blue light is a high-energy visible light emitted from digital devices like smartphones, tablets, and computer screens. Studies have linked overexposure to blue light with digital eye strain, disrupted circadian rhythms, and potential long-term retina damage:
- Digital Eye Strain – symptoms like headaches, blurred vision, dry/irritated eyes from prolonged screen time
- Circadian Disruption – blue light exposure at night suppresses natural melatonin production throwing off sleep cycles
- Potential Retina Damage – animal studies show blue light reaching the retina triggers cell death over time
While more research is still needed, taking precautions like using blue light blocking glasses has its benefits.
How Do Blue Light Blocking Glasses Work?
These specialized glasses use lenses designed to filter out or block blue light from entering the eyes. This alleviates digital eye strain, improves sleep quality, and protects retina health over time. They work in a few ways:
- Reflective lens coating to bounce back blue light
- Absorptive lens technology to take in and neutralize blue light
- Anti-reflective treatments also reduce glare and eye fatigue
When shopping, the level of blue light filtration varies by brand from 20% up to 90% blocked.
Reason #1: Alleviate Digital Eye Strain
Do you spend hours working on screens for your job? Reading emails on your phone before bed? Digital eye strain is no joke.
Symptoms include headaches, dry eyes, blurred vision, and neck/shoulder pain. Blue light blocking glasses can provide relief by filtering out the portion of light most likely causing issues. This allows you to comfortably continue device use without discomfort or reaching for the aspirin bottle.
Reason #2: Get Better, More Restful Sleep
Multiple studies demonstrate blue light exposure at night negatively impacts natural melatonin production – throwing off your circadian rhythm and making quality sleep difficult.
Since blue light tricks your brain into thinking it‘s still daytime, blocking it in the evening allows your body to produce melatonin on its natural schedule. This regulates sleep cycles leading to feeling more well-rested.
Reason #3: Reduce Risk of Retina Damage
Research on animal subjects indicates excessive blue light reaching the retina can damage light-sensitive cells over time contributing to macular degeneration.
While human studies are still limited, blue light blocking glasses provide a layer of protection against anything potentially harmful from screens. For intensive device users concerned about long-term eye health, these glasses offer preventative benefits.
Reason #4: More Comfortable Screen Viewing
Extended digital device use often leads to eye discomfort and fatigue. Reflective, absorptive lens coatings on blue light blocking glasses not only filter out harmful blue light but also reduce glare allowing for more comfortable viewing.
You can use devices for longer periods without squinting or straining your eyes. For outdoor use, polarized options also exist to cut glare when device viewing on sunny days.
Reason #5: Increased Work Productivity
Struggling with headaches, tired eyes, and mental fogginess thanks to too much screen time? Blue light blocking glasses to the rescue!
By filtering out eye-fatiguing blue light, these glasses boost work performance. Without vision discomfort or mental haziness sapping your concentration, you can be more productive and focused.
Reason #6: Maintain Healthy Circadian Rhythm
Our circadian rhythm regulates critical biological functions like metabolism and sleep-wake cycles. Exposure to too much blue light from screens late at night negatively impacts this natural process.
Using blue light blocking glasses in the evening minimizes disruption to your circadian clock. This maintains healthy functioning including promoting sounder sleep quality and regulating hormones linked to disease prevention.
How To Choose Blue Light Blocking Glasses
With all the options out there, choosing the right blue light blocking glasses depends on your needs:
Budget – Prices range from $10 to $300+ with higher-end brands generally offering better quality and durability. Find lenses with sufficient blue light filtration within your budget.
Style – From classic rectangular frames to cat-eye shapes to rimless – blue light blocking glasses now come in fashionable designs for both men and women.
Wrap-around Fit – Curved wrap-around frames limit light leakage from the sides of glasses – maximizing blue light filtering capabilities.
Screen Time & Devices Used – Consider how many hours a day are spent on screens and which devices you use most. This helps determine the level of blue light blocking you need. Power users may need glasses with 80-90% blue light filtration.
Single vs. Progressive Lens – Pick single, dedicated blue light blocking lenses or progressive everyday lenses with added blue light filters. The choice depends on whether you want separate glasses just for screen use or one pair for all-day wear.
Prescription – Many blue light blocking glasses brands offer prescription options including online glasses retailer Zenni and worn-by-celebs Felix Gray.
