The blue light glasses have yellow lenses that block both blue and green light. These glasses are perfect for evening use to support your body's natural circadian rhythm and help you wind down for a good night's sleep.
The optical yellow lenses block 80% of blue and green light in the 400-550 nm range - precisely the light spectrum that most disrupts the natural circadian rhythm and increases light sensitivity in the evening. That makes them ideal to wear before bed, when you want to find calm and prepare for sleep.

When and for how long should I wear the glasses?
Yellow blue light glasses are for daytime use - ideally all working day if you spend a lot of time in front of a screen. They're designed for extended wear and can be used for 8+ hours at a stretch without discomfort. In the evening, switch to orange or red lenses, which give stronger blocking closer to bedtime.
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
When should I wear yellow blue light glasses during the day?
Wear yellow blue light glasses when you're working at a screen for long stretches - typically 2+ hours at a time. They're ideal for office work, programming, design, reading digital documents or gaming. Yellow lenses filter out a significant part of the blue light without darkening your vision or noticeably distorting colours, so you see exactly as before while your eyes get some relief.
How long can I wear yellow glasses in front of a screen?
You can wear them all working day without any problem. Vesper™ yellow blue light glasses are designed for extended wear - many customers wear them 8+ hours a day at work. After a week of consistent use, most report less eye strain, fewer headaches and better concentration. They're a good investment for anyone who works digitally.
What's the difference between the yellow and orange filter?
Yellow lenses filter around 80% of blue light and are designed for daytime use without distorting colours. Orange lenses block around 97% and are worn in the evening to prepare the body for sleep. If you wear orange glasses during the day, colours look distorted and you'll feel tired. Wear yellow during the day and orange in the evening - and you've covered the whole day.
Do they really help with tired eyes from screen work?
Yes, many users report significantly fewer screen-related headaches after 1-2 weeks of consistent use. Headaches often come from eye muscles being overworked by blue light, along with reduced blinking when staring at a screen. Yellow blue light glasses reduce the strain on your eyes and can therefore reduce both the frequency and intensity of headaches.
Are yellow glasses suitable for driving?
Yellow lenses can actually improve vision in certain driving conditions - particularly in fog, rain or dusk, where they increase contrast. However, they aren't designed specifically for driving, and shouldn't be used in bright sunlight as they don't provide UV protection. When driving at night, yellow lenses can reduce glare from oncoming headlights.
Can I wear yellow glasses all working day?
Absolutely - that's exactly what they're designed for. Yellow blue light glasses can be worn continuously for 8-10 hours during a working day without discomfort. Many customers combine them with other measures such as adjusting screen brightness, taking short breaks every hour and blinking deliberately. Together, that gives noticeably less eye strain and better productivity.
