Why Even Consider Blue Blocking Glasses?
You can turn your phone off and still spend your entire evening under bright artificial light.
That is why this conversation goes beyond screens.
Kitchen lights, bathroom lights, television, stores and airports all contribute to the light reaching your eyes. The question is not simply, “How many hours was I on my phone?” It is also, “What kind of light am I surrounded by, and what time is it?”
Your Eyes Do More Than Help You See
Light helps set your internal clock. That clock influences your daily rhythm of alertness, sleepiness and melatonin release.
Blue light is naturally present in sunlight. It is not automatically the enemy. The important distinction is the timing, brightness and overall light environment.
During daylight hours, outdoor light provides a strong daytime signal. After sunset, bright artificial lighting can keep sending an alerting signal when you are trying to wind down.
You might feel physically tired while your environment is still telling your brain to stay awake.
What I Take From Dr. Jack Kruse’s Approach
One reason Dr. Jack Kruse’s work resonates with me is his emphasis on looking at our environment, not just what we eat or which supplements we take.
His approach prioritizes natural daylight and reducing artificial light exposure, especially after sunset. In his writing, he recommends starting with nighttime blue blockers, then considering daytime filtering lenses when spending time indoors under blue-rich lighting.
That distinction matters. Daytime indoor lenses and nighttime lenses are different tools, not interchangeable glasses.
Neuroscientist Andrew Huberman also emphasizes outdoor morning light and reducing bright evening lighting. He describes nighttime blue blockers as a potentially helpful addition, while stressing that you should still dim the lights. His recommendations are not identical to Kruse’s, but this is an important point of overlap.
Where Glasses Fit Within ANSWERS™
Within my ANSWERS™ framework, this begins with Awareness: noticing the environment you spend your day in.
Sunshine reminds us to reconnect with natural daylight. Replenish and Stillness invite us to create evenings that support winding down instead of extending daytime stimulation right up until bed.
Blue blocking glasses can be one practical tool when you cannot control the lighting around you. They filter selected wavelengths before that light reaches your eyes.
But they do not replace daylight, make every late-night habit harmless or guarantee better sleep.
Start with the foundations and get outdoors during the day, reduce unnecessary artificial light, and make your evenings dimmer. Then consider whether a daytime or nighttime pair would help you manage the light you cannot avoid.
I purchased glasses because on occasion, I am working late on my computer or phone or I may want to watch movies with my kiddos.
The goal is not to become afraid of light. It is to become more intentional about it.
Blue Blocking Glasses I’m Considering
I’ve been researching daytime and nighttime glasses from four companies: TrueDark, CHROMA, Lucia Eyes and BlockBlueLight.
I have not personally tested these glasses yet. This is my research shortlist, based on their published lens information and available customer reviews. Once I choose my pairs and use them consistently, I’ll circle back with my own experience.
Customer reviews can help us understand comfort, fit and everyday usability. They cannot guarantee that we will experience the same results. Review counts and prices also change, and some brands combine reviews across frame colors or lens options.
TrueDark
Daytime: Daylights Elite
The Daylights range is TrueDark’s daytime option for screens and indoor artificial lighting.
The Elite listing shows approximately 4.9 out of 5 stars from 84 reviews. In the reviews I checked, buyers praised its lightweight feel and reported more comfortable daytime screen use.
Nighttime: Twilights Elite
This is TrueDark’s deep-red nighttime option.
The listing shows approximately 4.9 out of 5 stars from 72 reviews. One detailed reviewer praised the sturdy construction and generous lens coverage but described a strong red color shift and some light entering underneath the frame.
My takeaway: a candidate for evening use, but the oversized aviator design deserves a careful fit check, particularly for smaller faces like mine.
CHROMA
Daytime: Golden Glo
CHROMA describes Golden Glo as a selective daytime filter rather than a lens designed to block all blue light.
The customer feedback I could access on the Golden Glo Sentinel page included reports of more comfortable work lighting and screen use. However, that page also displayed a review referring to the Horizon frame, so I would not treat its rating as specific to Sentinel alone.
One reviewer specifically cautioned that the fit suited a medium-to-large head and might not suit smaller heads.
My takeaway: an interesting daytime option, but I would confirm the exact frame dimensions rather than assume every Golden Glo style fits alike.
Nighttime: Nightshades
CHROMA markets Nightshades for evening use, filtering blue and green wavelengths while allowing some violet light through.
The Nightshades Agent page displayed 5 out of 5 stars from 31 reviews. I could not verify an equally clear review breakdown for the Classic frame, so I am not transferring that rating to Classic or treating it as a brand-wide score.
My takeaway: still on my nighttime shortlist, but I want more information about the particular frame’s fit before choosing one.
Lucia Eyes
Daytime and Nighttime: Dr. Jack Kruse Frame
Lucia lists daytime and nighttime lens options on this product page. The company describes its daytime option as filtering 50% of blue light and its nighttime option as blocking blue and green light.
The page displays 3.8 out of 5 stars from 37 reviews. These reviews are not clearly separated into daytime and nighttime lens experiences.
Positive comments mention lens quality, comfort and satisfaction with the glasses. Complaints include incorrect sizing, loose or misaligned frames, case problems and difficulty getting customer-service responses. Some buyers also found the tint darker or more orange than expected.
My takeaway: I would resolve sizing and exchange questions before ordering. The Kruse frame comes in medium and extra-large, so it is not my automatic choice for a petite face. His name on the frame matters less than whether it fits properly.
BlockBlueLight
Daytime: DayMax Billie
BlockBlueLight states that its yellow DayMax lens filters approximately 70% across the 400–500 nm blue-light range, with stronger filtering in the shorter wavelengths.
The listing shows 4.9 out of 5 stars from 75 reviews. Reviews I checked included reports of less screen-related discomfort during long workdays and a more comfortable experience under classroom fluorescent lighting.
The daytime Billie page lists a 130 mm frame width, 49 mm lenses and 140 mm arms.
My takeaway: one of the first daytime frames I want to compare with my current petite glasses. Those measurements are a starting point, not a promise of fit.
Nighttime: NightFall Billie
BlockBlueLight states that its red NightFall lens blocks blue and green light through 550 nm.
The listing shows 4.9 out of 5 stars from 167 reviews. Buyers describe using them for evening television and reading on an iPad. Some report finding it easier to unwind. One reviewer noted that the strong lens color takes getting used to.
An important sizing detail: this page lists a 136 mm frame width and 150 mm arms, unlike the smaller measurements on the daytime Billie page. I would ask the company to confirm the current measurements before buying both.
My takeaway: a nighttime candidate, but matching frame names do not necessarily mean matching fit.
What Will Decide My Purchase?
I’m looking for the right lens for the time of day, a comfortable fit and clear information about exchanges if the glasses do not work for my face.
I do not need every shade from every brand. My starting point is one daytime indoor pair and one nighttime pair.
Once I’ve used my choices consistently, I’ll update this post with what I actually notice, including comfort, color changes, practicality and whether they earn a place in my routine.
