Warranty
Do SleepSpec glasses come with a warranty?
Yes! All SleepSpec glasses come with a 1-year warranty against manufacturing defects within 12 months from your purchase date. This covers defects in materials or workmanship, such as frame defects, lens defects, and hardware failures under normal use. The warranty does not cover damage from accidents, drops, misuse, or normal wear and tear.
How do I clean my lenses?
Clean your SleepSpec lenses with the provided microfiber cloth and lens cleaning solution, or use mild soap and lukewarm water. Avoid harsh chemicals, paper towels, or rough materials that could scratch the specialized FL41 coating. Always dry with the microfiber cloth in gentle, circular motions.
Technical
How do I know which glasses will fit my face best?
SleepSpec glasses feature a Universal Fit Design with classic rounded frames that complement all face shapes. Our TR90 frame technology provides flexibility and comfort for extended wear. We recommend checking the product specifications for frame dimensions before ordering.
What makes SleepSpec different from regular computer glasses?
SleepSpec glasses are specifically engineered for evening use, 1-2 hours before bedtime. While computer glasses focus on reducing daytime eye strain, our glasses block 98%+ of sleep-disrupting blue light (400-530nm wavelength) to support natural melatonin production and improve sleep quality.
Sleep Science FAQs
Light & Sleep Questions
What is blue light and how does it affect sleep?
Blue light, particularly in the 450-490nm wavelength range, is the most potent suppressor of melatonin, your body's natural sleep hormone. Evening exposure to blue light from screens and artificial lighting tells your brain it's still daytime, delaying natural sleepiness and disrupting your circadian rhythm.
What is circadian rhythm and why is it important?
Your circadian rhythm is your body's internal 24-hour clock that regulates sleep-wake cycles, hormone production, and other vital functions. Maintaining a healthy circadian rhythm is crucial for quality sleep, cognitive function, mood regulation, and overall health.
Where can I find more information about blue light research?
SleepSpec's recommendations are based on peer-reviewed scientific studies. You can find research citations and more detailed information about blue light and sleep science in our blog section and scientific resources page.
SleepSpec Technology
What wavelengths do SleepSpec glasses block and how much?
SleepSpec glasses block 98%+ of blue light in the critical 400-530nm wavelength range, with particular focus on the 450-490nm range that most disrupts melatonin production. Our FL41 orange-tinted lenses are specifically calibrated for optimal sleep support.
How do SleepSpec glasses work?
When worn 1-2 hours before bedtime, SleepSpec glasses filter the specific blue light wavelengths that suppress melatonin production. This allows your body to naturally begin its wind-down process, making it easier to fall asleep and improve overall sleep quality.
Why should I choose SleepSpec over other blue light glasses?
SleepSpec glasses are specifically designed for pre-sleep use, not all-day wear. Our focus on the critical evening window, combined with our scientifically-validated 98%+ blocking rate and affordable £30 price point, makes us the most effective choice for sleep enhancement.
Usage & Timing
When should I wear my SleepSpec glasses?
Wear your SleepSpec glasses for 1-2 hours before your intended bedtime while using any digital devices or under artificial lighting. This timing allows your body's natural melatonin production to begin unhindered.
Who should wear SleepSpec glasses?
SleepSpec glasses are particularly beneficial for poor sleepers, night owls, teenagers, digital professionals with heavy screen exposure, and anyone experiencing sleep difficulties potentially linked to evening screen time. Research shows especially strong benefits for people with irregular sleep patterns.
Can I wear SleepSpec glasses while driving?
No, do not wear SleepSpec glasses while driving, especially at night. The orange tint may affect your ability to see traffic lights and other important visual signals clearly. These glasses are designed specifically for indoor evening use before bedtime.
Can I continue using my devices while wearing SleepSpec glasses?
Absolutely! SleepSpec glasses are designed to let you continue your normal evening routine - reading, watching TV, using your computer or phone - while protecting your natural sleep cycle from blue light disruption.
Kids & Teens
Are SleepSpec glasses suitable for teenagers?
Research shows teenagers are particularly sensitive to blue light due to their clearer eye lenses. Studies found teens fell asleep 62% faster when wearing blue light blocking glasses before bed compared to adults who saw minimal improvement. SleepSpec glasses can be especially beneficial for teens with heavy evening screen use.
What age is appropriate for SleepSpec glasses?
All Ages are suitable.
Fit & Comfort
What if the glasses don't fit properly?
SleepSpec glasses feature flexible TR90 frame technology and Universal Fit Design to accommodate most face shapes. If you experience significant fit issues that affect the product's function, this may be covered under warranty as a design defect. Please contact customer service to discuss your specific situation.
Can I wear SleepSpec glasses over my prescription glasses?
Our current model is designed as standalone glasses, but they can be worn over most prescription glasses. While we're working on developing prescription lens options for the future, wearing SleepSpec over your existing glasses is a practical solution in the meantime.
