Win the Night: Choosing Your Blue Light Shields
When the sun goes down, our bodies should naturally prepare for sleep. But modern life has introduced a glaring problem: blue light from screens can mess with our internal clocks. That’s where blue light blocking glasses come in. They’re not just a trend; they’re a tool to help you reclaim the night and ensure restful sleep.
The Importance of Blocking Blue Light for Sleep
Our bodies follow a natural rhythm, largely dictated by light. The blue light emitted by screens mimics daylight, tricking our brains into thinking it’s still daytime. This can delay the production of melatonin, the hormone that helps us sleep. So, blocking this light as evening approaches is crucial for a good night’s rest.
Clear vs Amber vs Red: Know Your Options
When it comes to blue light glasses, you’ve got options. Clear, amber and red lenses each have their place. Amber lenses are great for evening use, red lenses might just take your sleep to the next level, and clear lenses can help with daytime screen use. But let’s dive deeper to understand why and how these lenses work.
Clear Lenses: Style Confronts Function
Clear lenses have a sleek, almost invisible look, making them a stylish choice for daytime wear. They offer a more subtle way to protect your eyes from blue light without the noticeable tint of amber or red lenses. But when it comes to sleep, style should never trump function.
The Effectiveness of Clear Lens
While clear lenses may filter out some blue light, they don’t provide the same level of protection as amber or red lenses. They’re designed for people who are concerned about eye strain from digital screens during the day, not necessarily for improving sleep at night. That’s why they’re best suited for daytime use, rather than as part of your pre-bedtime routine.
When to Opt for Clear Over Tinted Glasses
There are times when clear lenses might be the right choice. If you’re working in an environment where color perception is crucial, or if you’re simply not ready to commit to the tinted look, clear lenses can be a good starting point. They can help reduce eye strain without altering the colors of your digital screens too much.
Amber Lenses: The Gold Standard?
Amber lenses are often touted as the gold standard for blocking blue light effectively. Their tint has been specifically designed to filter out the blue and some green light frequencies that can keep you awake. This makes them an excellent choice for use in the hours leading up to bedtime.
Cutting Through Blue and Green Light
Why focus on cutting out blue and green light? Because these are the wavelengths that most significantly impact our circadian rhythms. By filtering them out, amber lenses can help signal to your body that it’s time to wind down, making it easier to fall asleep and stay asleep.
But not all amber lenses are created equal. To get the best results, you’ll want lenses that block at least 90% of blue light. This level of protection ensures that your eyes are shielded from the light that can disrupt your sleep cycle.
How Amber Glasses May Benefit Your Sleep Cycle
Wearing amber-tinted glasses can have a profound effect on your sleep quality. By blocking disruptive light, they can help regulate your sleep-wake cycle, leading to more restful nights. This can mean falling asleep faster and experiencing fewer awakenings throughout the night.
Most importantly, remember to put them on 2-3 hours before you plan to hit the hay. This gives your body enough time to ramp up melatonin production and prepare for sleep.
Red Lenses: Blocking Green for Serenity
It’s not just blue light that can disturb our sleep; green light also plays a role. While not as widely discussed, green light has similar effects on our sleep patterns. Red lenses take it a step further than amber by blocking both blue and green light. This can be especially helpful for those who are particularly sensitive to light before bedtime or who work night shifts and need to sleep during the day.
Comparing Key Points
| Lens Color | Blocks Blue Light | Blocks Green Light | Recommended for Insomnia |
|---|---|---|---|
| Clear/Yellow | No/Minimal | No | Clear or yellow lenses do not block enough blue light wavelengths to have a positive impact on sleep and melatonin production, so they are not recommended for insomnia[3] |
| Amber | Yes (100%) | No | Amber lenses block 100% of blue light wavelengths and are recommended for use 2-3 hours before bedtime to improve sleep quality[3]. |
| Red | Yes (100%) | Yes (up to 550nm) | Red lenses block 100% of both blue and green light wavelengths up to 550nm, which are the exact wavelengths shown to most affect the body’s internal clock and melatonin levels. Red lenses are highly recommended for maximizing sleep quality and treating insomnia[3][4]. Blocking both blue and green light wavelengths is important for allowing maximum melatonin production and aligning with the body’s natural sleep/wake cycle[3]. In summary, for individuals struggling with insomnia, red lenses that block both blue and green light are considered the most optimal choice for improving sleep quality and melatonin production[3][4]. |

Findings: Clear vs Amber vs Red
Choosing the right blue light blocking glasses boils down to understanding your lifestyle and needs. Answering these questions can guide you to the right pair.
- How much are you willing to adjust your appearance for the sake of better sleep?
- Are you sensitive to light?
- Do you spend long hours in front of a screen at night?
Understanding Your Personal Needs
Everyone’s eyes and sleep needs are different. Some may find significant sleep improvements with amber lenses, while others might need the extra blocking power of red lenses. And for those who need to stay stylish and functional during the day, clear lenses are there to help. It’s all about personalizing your approach to sleep health.
For example, if you’re an artist who works late into the night, you might opt for amber lenses to help you wind down after a long day of creative work. On the other hand, if you’re a gamer who plays well into the wee hours, red lenses could be your ticket to better sleep. And if you’re a programmer (or even a blogger) who spends all day in front of a computer, clear lenses can protect your eyes without compromising the vividness of your screen.
Tips for Testing and Adapting to Tinted Lenses
Transitioning to blue light blocking glasses can take some getting used to. Start by wearing them for a short period each evening, gradually increasing the time as your eyes and brain adjust. Pay attention to how you feel and how well you sleep. Adjusting to the tint can be a process, but it’s worth it for the sake of your sleep health.
