Questions?
We've got answers
Is blue light really a problem?
Blue light itself is not bad, but it depends on the timing. Natural blue light from the sun is beneficial during the day. It keeps us awake, alert and helps regulate our natural body clock. Artificial blue light from screens, especially in the evening, is the real problem. Blue light after sunset can suppress melatonin by up to 70 percent, delay your circadian rhythm by more than three hours, make you feel 50 percent less tired and cause you to take up to 30 minutes longer to fall asleep.
Do anti-blue light glasses really work?
As studies from Harvard have shown, blue light blocking glasses are designed to filter out artificial blue wavelengths emitted by digital screens. This helps reduce eye strain, fatigue, headaches, and sleep disruption caused by prolonged screen exposure. Many individuals have experienced greater relaxation and deeper sleep as a result.
What is the difference between the Day and the Night Lenses?
The Day lenses are ideal for long work sessions or daytime use. They offer higher visual comfort with lighter protection, helping you stay focused while reducing fatigue, eye strain and headaches.
The Night lenses are designed to promote deep, restorative sleep so you wake up feeling refreshed. Their higher blue light blocking percentage supports melatonin production and lowers cortisol levels, benefits that are not needed during the day.
Using both lenses together ensures optimal daily performance, enhancing your overall health, focus and energy levels.
How long before bed should I put my glasses on?
We recommend wearing the night glasses 2 to 3 hours before going to sleep. This helps prevent disruption of your natural melatonin production process, allowing your body to unwind and prepare for deep, restorative sleep
For best results, use the day glasses earlier in the day to prevent eye strain, headaches and to help lower cortisol levels with their lighter tint. Then switch to the night glasses before bedtime to prepare your body for restful sleep.
What’s the difference between PUREWELL lenses and clear blue light glasses?
Most clear blue light glasses on the market block less than 10% of harmful artificial blue light. PUREWELL lenses block the full range of Artificial blue light, providing the benefit of true blue light blocking glasses.
How is PUREWELL different from cheaper similar products?
PUREWELL is not focused on producing low-cost products. Our mission is to deliver premium quality and complete protection supported by science.
All our lenses are thoroughly tested and meet the highest standards of optical quality available. Unlike cheaper alternatives, our products are developed with advanced technology, high-grade materials and carefully engineered designs.
