Understanding Blue Light and It’s Effects
Blue light is a high-energy visible light emitted by the sun and digital devices like smartphones, computers, and tablets. While natural blue light exposure during the day helps regulate our circadian rhythm, excessive exposure, especially at night, can wreak havoc on our sleep patterns and potentially cause long-term eye damage.
With the average person spending over 7 hours a day looking at screens, our eyes are under more strain than ever before. This prolonged exposure often leads to symptoms like eye fatigue, headaches, blurred vision, and difficulty focusing – collectively known as digital eye strain or computer vision syndrome.
And, blue light exposure in the evening interferes with our body’s production of melatonin, the hormone responsible for regulating our sleep-wake cycle. This interference can result in difficulty falling asleep, poor sleep quality, and daytime fatigue.
The Science Behind Blue Light Blocking Glasses
Blue light blocking glasses work by filtering out or blocking the blue light emitted from digital screens. The lenses typically have a slight yellow or amber tint, which helps absorb blue light.
Some advanced lenses can block up to 99 percent of blue light while maintaining color accuracy.
These glasses help reduce digital eye strain but can also improve sleep quality when worn in the evening. By blocking blue light, they allow your body to produce melatonin naturally, helping you fall asleep more easily and enjoy more restful sleep.

Choosing the Right Blue Light Blocking Glasses
When selecting blue light blocking glasses, consider the following factors:
Blocking Percentage
Look for glasses that block at least 90 percent of blue light for most effectiveness. However, keep in mind that higher blocking percentages often come with a stronger amber tint, which may affect color perception.
Comfort
Ensure the frames fit comfortably, especially if you plan to wear them for extended periods. Look for features like adjustable nose pads, spring hinges, and lightweight materials.
If possible, try on the glasses or check the return policy before making a purchase.
Style
Choose a style that you’ll be happy wearing regularly, whether at work or at home. Consider your personal style and the environments where you’ll be wearing the glasses.
Some models, like the Felix Gray Nash, offer a more professional look, while others, like the Gunnar Intercept, have a more casual or sporty appearance.
Lens Tint
Decide whether you prefer a stronger amber tint for most blue light blocking or a clearer lens for better color accuracy. Amber tints are generally more effective at blocking blue light but may alter color perception.
Clear lenses maintain color accuracy but may not block as much blue light.
Prescription Compatibility
If you wear prescription glasses, look for blue light blocking options that can accommodate your prescription. Some brands, like Swanwick, offer prescription options, while others may be designed to fit over your existing glasses.
Maximizing the Benefits of Blue Light Blocking Glasses
To get the most out of your blue light blocking glasses:
Consistent Use
Wear them consistently when using digital devices, especially in the evening. Consistency is key to reaping the full benefits of blue light blocking glasses, particularly for improving sleep quality.
Combine with Other Eye-Care Practices
Use your blue light blocking glasses in conjunction with other eye-care practices, such as the 20-20-20 rule (every 20 minutes, look at something 20 feet away for 20 seconds). This comprehensive approach can significantly reduce digital eye strain.
Adjust Device Settings
In addition to wearing blue light blocking glasses, adjust your device settings to reduce blue light emission, particularly at night. Many devices now have built-in blue light filters or “night mode” settings that can complement the effects of your glasses.
Day and Night Pairs
Consider using different pairs for day and night use. Daytime blue light exposure can be useful for maintaining a healthy circadian rhythm, so you might opt for glasses with a lighter tint during the day and switch to a stronger tint in the evening.
