Blue light lenses are gaining popularity as people become more aware of the potential damage caused by blue light to our eyes. These lenses filter out harmful blue light from digital devices like computers, tablets, and smartphones. 

While there are not enough studies to definitively prove the effectiveness of blue light lenses in reducing digital eye strain, preventing dry eyes, or protecting against macular degeneration, they can still help regulate sleep-wake cycles and circadian rhythms. This can have several benefits, including hormone regulation and increased alertness and may help manage depression and anxiety.

With these abilities, blue light lenses are excellent for those who spend a lot of time in front of screens, promoting better overall health and comfort for the eyes.

Understanding Blue Light & Its Effects on Vision

Blue light is part of the visible light spectrum and is emitted by the sun and digital devices like laptops, smartphones, and LED lights. It’s a high-energy, short wavelength. 

We need blue light from the sun as it provides many positive effects, including heightened attention, improved reaction times, and an uplifted mood. You may have heard that blue light emitted by electronics is bad for your eyes, but this claim lacks concrete scientific evidence.

However, excessive exposure to blue light, especially in the evening, can disrupt the delicate balance of your body’s innate sleep-wake cycle, affectionately known as your circadian rhythm.

Do You Need Blue Light Lenses?

Blue light lenses block blue light to minimize its impact on your circadian rhythm, which is particularly important for those who spend a lot of time using digital screens or in LED-lit rooms.

But it’s essential to be mindful of your total amount of blue light exposure, regardless of whether or not you use blue light glasses. A good rule of thumb is to limit device use in the evening and take frequent breaks during the day. 

Additionally, using dimmable lighting can replicate the soft hues of natural light and create a relaxing atmosphere that can help you fall asleep more easily.

The Benefits of Blue Light Lenses

Blue light lenses have become increasingly popular in our digital age. While there’s no proof they protect against certain eye conditions, there are well-documented benefits, particularly in regulating our sleep-wake cycle.

Hormone Regulation

Exposure to blue light, particularly during the evening, has been shown to disrupt melatonin production, the hormone responsible for regulating our sleep-wake cycle. This disruption can lead to difficulties falling asleep and achieving restful sleep. 

Blue light lenses can help mitigate the impact of blue light by limiting how much reaches your eyes, supporting the natural release of melatonin and promoting a more restful and rejuvenating sleep.

Blue light lenses can help signal to our bodies that it’s time to wind down and prepare for a restful sleep. This, in turn, can contribute to increased alertness and productivity during the day, as we give our bodies the essential rest and rejuvenation they require for optimal performance. So, incorporating blue light lenses into our routine can be a valuable step towards achieving a well-balanced and energized lifestyle.

Depression & Anxiety Management

Research has consistently indicated a connection between disrupted sleep and susceptibility to depression and anxiety. Blue light lenses can effectively regulate our sleep-wake cycle and indirectly support mental health. These lenses promote healthier sleep patterns and overall well-being.

Blue light lenses may contribute to improved hormone regulation and alertness and provide benefits for managing depression and anxiety.

But blue light lenses are not only helpful for those who spend time in front of digital devices—they can also be beneficial for outdoor use, such as when engaging in activities in direct sunlight. These lenses help reduce glare and make it easier to focus on your activity or enjoy the scenery around you.

Additional Tips

In addition to wearing blue light glasses, there are some steps you can take to lessen the symptoms associated with too much blue light. This includes:

  • Practice the 20-20-20 rule: Take a break from digital devices every 20 minutes to look at something 20 feet away for 20 seconds. This gives your eyes a break from the screen and helps them relax. 
  • Use eye drops: Eye drops can keep your eyes lubricated throughout the day if you are experiencing dry eyes from blue light.
  • Avoid too much screen time and sunlight: The best way to lower your exposure to blue light is by limiting how much time you spend looking at devices or in the sun. 
  • Distance yourself from screens: To avoid blue light exposure, sit an arm’s length away from your screen. 
  • Using screen filters: You can install or enable certain screen filters that lower blue light exposure on certain digital devices.
  • Adjust your lighting: If you have LED bulbs in your home and you cannot change them, consider adding additional light sources that do not use LED bulbs.
  • Wear sunglasses: If you spend a lot of time in the sun, your eyes will be exposed to large amounts of blue light. Wear sunglasses to protect your eyes. 

Taking care of your vision and eye health is a crucial component of your overall wellness. Book an appointment with your eye care professional to determine whether or not blue light glasses are the proper treatment for you.
