Red vs orange blue light glasses: differences and when to wear
Red vs orange blue light glasses: the short answer is orange for daytime and early evening, red for the last 1–2 hours before bed. The reason is a trade-off between filtering and colour accuracy that you weigh differently depending on the time of day. The redder the lens, the more short-wavelength light it blocks, but the more it distorts colours.
Here we compare both tints in practical terms, show which lenses were actually tested in studies, and tell you honestly when a second pair is worth it and when it is not.
First, some context: whether blue light glasses improve sleep has not been clearly settled by research. You will find the full evidence in our guide do blue light glasses help sleep. This article deals with the practical question that comes next: if you want to use a pair, which tint fits when?
What is the difference between red and orange lenses?
A tinted lens works like a colour filter. It lets long-wavelength light through, meaning yellow, orange and red, and holds back short-wavelength light. The further the tint moves towards red, the more of the spectrum is cut off: first blue, then blue-green and part of green as well.
This matters for sleep because the retinal cells that set your body clock respond most strongly to blue. A 2001 study (Brainard et al.) found the strongest melatonin suppression at wavelengths between 446 and 477 nanometres. Slightly longer wavelengths still have an effect, just a weaker one. A red tint therefore also catches the edge zones that an orange tint partly lets through.
The price is colour perception. Through orange lenses the world looks warmer, but you can still tell red, yellow and green apart. Through red lenses many colours look alike and blue appears very dark. On the sofa in the evening that hardly matters; for a spreadsheet or a colourful game menu in the afternoon it does.
Red and orange side by side
The filter values in this table are manufacturer figures from our product data. We do not have independent transmission measurements.
| Feature | Red blue light glasses | Orange blue light glasses |
|---|---|---|
| Blue light filter (manufacturer figure) | 100% of blue light | 99% of blue light |
| Effect on colours | strongly red, colours hard to tell apart | warm tone, colours easy to recognise |
| Intended time of use | last 1–2 hours before bed | daytime and early evening |
| Typical situations | a series, reading on a tablet, the last round of gaming | office, gaming, streaming |
| Not suitable for | everyday daytime use, driving | colour-accurate work such as photo editing |
| Lenses | 7-layer coating (blue light, anti-reflective, scratch-resistant), UV400, no prescription | |
| Frame | 20 g, square or round, unisex | |
What do studies show about orange and red lenses?
To be honest, research has mostly looked at orange and amber lenses. A 2006 study (Sasseville et al.) exposed 14 people to bright light at night. With orange lenses, melatonin did not change significantly; with grey lenses of the same brightness it dropped by 46 per cent. A 2018 randomised trial (Shechter et al.) with 14 people with insomnia symptoms used amber lenses for 2 hours before bed. Participants reported better sleep; objectively, only total sleep time was longer.
In our research we did not find a study that compares red and orange lenses head to head for sleep. The logic behind red lenses for the final hours makes physical sense, because they hold back more short-wavelength light. But it is not proven that you will sleep better with red than with orange. For blue light glasses in general, a 2023 Cochrane review rates the evidence on sleep as very uncertain.
Worth knowing
Clear "blue light filter" lenses from an optician are a different thing. They filter only a small part of blue light and have hardly been studied for sleep. The studies that found effects on melatonin used clearly tinted lenses.
When should you wear which pair?
The easiest way is to think in times of day. During the day, bright light is generally good for your rhythm, so you do not need to block it out completely. In the evening that flips.
- At the office or working from home: orange, if you find the warmer tone comfortable. You should know that Cochrane found no proven benefit against tired eyes.
- Gaming or streaming in the afternoon and early evening: orange. You can still read menus, maps and in-game colours well.
- The last 1–2 hours before bed: red. Here, maximum filtering matters more than colour accuracy.
- After a late shift or a night flight: the pair that suits what you do next. If you want to sleep soon, red. Shift work has its own recommendations; if you struggle, talk to occupational health.
For what such an evening can look like, see our plan for late-night GTA 6 gaming sessions.
"My advice: choose the pair you will actually wear. Red glasses that stay in a drawer because they ruin the colours while you game do nothing for you. Better to go with orange and wear them every evening."
Do you need both pairs?
Not necessarily. It depends on when you use screens. If you are unsure, start with the pair for the time of day when you spend longest on screens. After two or three weeks you will know whether you actually wear them and whether something is missing for the evening or the day. That way you do not buy something that ends up in its case.
| Your routine | Our recommendation |
|---|---|
| Screens mainly in the evening, goal is to wind down | red pair |
| Lots of screen time during the day, little in the evening | orange pair |
| Office by day, gaming or series in the evening | both: orange by day, red before bed |
| Evening gaming where colours need to be right | orange until near the end, then red for the final stretch |
The red blue light glasses for the evening and the orange blue light glasses for daytime share the same frame and coatings and differ only in the tint.
What to look for in blue light glasses
Red or orange, a few points decide whether you will actually wear them day to day:
- A visible tint: for the evening, a strongly tinted lens is what counts. A barely visible sheen filters too little.
- Weight and fit: glasses that pinch end up on the table after ten minutes. Our frames weigh 20 g and come in square (141 mm frame width) or round (139 mm).
- Anti-reflective coating: otherwise tinted lenses reflect lamps and screens. Both versions have an anti-reflective and a scratch-resistant layer.
- Honest claims: check whether a brand gives percentages and explains what the glasses are for. Promises such as "cures insomnia" are a red flag.
Common mistakes with red and orange glasses
Most problems have nothing to do with the tint and everything to do with how the glasses are used:
- Glasses off, phone on: if you take the red pair off and scroll in bed for ten minutes, the light reaches you unfiltered again.
- Orange until you fall asleep under bright ceiling lights: for the final stretch, dim the lights and switch to red.
- Red in the afternoon: unnecessary and it makes daily life harder. During the day, light tends to help your rhythm.
- Irregular bedtimes: no tint makes up for going to bed at a different time every night.
Who blue light glasses suit, and who they do not
A good fit if you
- regularly spend your evenings on a console, PC or tablet
- want a fixed evening routine that clearly ends the day
- have long screen time during the day and like the warmer tone
Not suitable, or not enough, if you
- would need to drive while wearing tinted lenses
- do colour-accurate work for a living
- have been sleeping badly for weeks. Please see your GP; glasses are not a treatment.

Conclusion
Orange is the pair for the day and early evening, red the one for the last 1–2 hours before bed, because it filters more but changes colours heavily. Owning both makes most sense if you spend a lot of time on screens both during the day and in the evening; otherwise the pair for your main screen time is enough. Studies have mainly tested orange and amber lenses, an advantage of red for sleep has not been directly shown, and no pair of glasses replaces seeing a doctor if sleep problems persist.
