Vesper™ Blue Light Blocking Glasses have our signature red lenses that block both blue and green light. These are the most effective blue light glasses for improving sleep and supporting your body's natural evening rhythm.
Blue light from screens - phone, computer and TV - reduces melatonin and is very disruptive to sleep. With Vesper glasses you can use a screen before bed without it costing you sleep quality.
The optical red lenses block 99% of blue and green light in the 400-550 nm range - precisely the spectrum that clinical studies have shown reduces melatonin and impairs sleep quality.

When and for how long should I wear the glasses?
Wear red blue light glasses for the last 1-2 hours before bed, when melatonin production is at its most vulnerable. They're stronger than orange lenses and block all blue and green light. For earlier evening use (4+ hours before bed) we'd recommend orange lenses instead, for more natural colour rendering.
Why does blue light impair sleep quality?
Blue light is a type of high-energy light that occurs naturally in daylight but is also emitted from digital displays, LED lights, and other artificial light sources. This light affects your circadian rhythm – the body's biological clock that regulates when you feel awake and when you feel tired. During the day, blue light plays an important role in keeping us awake and focused, but exposure to it late in the evening can inhibit the production of melatonin – the hormone that makes us sleepy.
Sleep glasses block exposure to blue light in the evening and before bedtime. This helps the body maintain natural melatonin production, which can improve sleep quality. Whether you're working late, watching television, or using your mobile phone, these glasses help balance lighting conditions and prepare your body for a good night's sleep.

Frequently Asked Questions
How much blue light does the red filter block?
Vesper™ red blue light glasses block 99% of blue and green light up to 550 nanometres. That's the strongest filtering we offer, and it's ideal for the last 1-2 hours before bed, when you want to maximise your body's own melatonin production. Compared with the orange filter (which blocks around 97%), the red filter gives almost total blocking of the disruptive wavelengths.
Should I choose the red or orange filter?
It depends on when you'll be wearing them. Choose orange if you want versatile glasses for evening use 2-4 hours before bed (socialising, TV, dinner). Choose red if you have significant sleep problems or want to wear them right before bed (1-2 hours before). Many experienced users have both - orange for the evening and red for late at night.
What time in the evening is the red filter best to use?
The last 1-2 hours before you go to bed. That's the period when your body produces the most melatonin, and even small amounts of blue or green light can suppress production. The red filter blocks 99% of these wavelengths and lets your body prepare for sleep as well as possible. Many people wear them from around 9-10pm until bedtime.
Is the red filter too strong for everyday evening use?
For early evening use (4+ hours before bed), the red filter can be stronger than necessary - orange lenses work better there. The red filter distorts colours more because it blocks all blue and green light, so colourful programmes can look a little different. But late in the evening, that maximum blocking is a real advantage.
Which sleep problems do red glasses help with?
Red blue light glasses are particularly useful for people who struggle to fall asleep, sleep restlessly, wake frequently during the night or have a disrupted circadian rhythm (from shift work, for example). They're also effective against 'social jetlag' and for people who are very sensitive to blue light. Combined with consistent use and good sleep hygiene, they often give a noticeable effect after a short time.
Can I wear red glasses outside the house?
Yes, but they're designed primarily for indoor use in the evening. The red colour is very visible and can draw attention, and it distorts your surroundings more than an orange filter does. For evening social occasions we'd recommend orange lenses instead - for use at home and before bed, red glasses are ideal.
