Blue Light Blocking Glasses for Sleep - Amber Nighttime Eyewear

Product Details: Imported from China, these glasses are designed to fit over prescription and reading glasses, or they can also be worn on their own. The Spectra479 amber lenses provide superior blue light blocking, turning your regular glasses into anti-blue light glasses for computer and nighttime TV use. The lenses are bright and clear, allowing for non-blue light to pass through without a dark tint or polarization, so you can still make eye contact with loved ones comfortably.

Key Product Features: - Technical Specs: Tested to block 100% of light from 280 - 490nm, including UV, and over 99.9% of light in the critical 450 - 510nm range, the most disruptive wavelength of light at night. - Product Description: Blue light exposure after dark can disrupt your natural melatonin production, affecting your body's internal clock. Shield your eyes from blue-rich LED and fluorescent lights to support nighttime physiology and improve sleep onset and quality.

The Disruption Zone: While the body is sensitive to various visible light levels, the range of 450 - 510nm is the most disruptive, challenging for clear and yellow-tinted lenses to block effectively. By using these blue light blocking glasses, you can create a virtual darkness environment to protect your eyes and maintain a healthy circadian rhythm wherever you go.

Fits Over Your Glasses: Rather than investing in expensive custom blue blockers, these lightweight glasses can be worn over your existing prescription or reading glasses, instantly transforming them into effective blue light blockers. They can also be worn alone, providing flexibility for occasional glasses wearers.

Ease of Use: These glasses easily fit over your regular glasses without any clips, making it convenient for those who use multiple glasses or wear them only part of the time. Simply put them on whenever you need to shield your eyes from blue light, whether using screens before bed or throughout the day.

Don't let blue light affect your sleep or eye health. Protect yourself with these blue light blocking glasses for instant relief from eye strain and fatigue caused by shortwave blue light exposure. Block out harmful blue light and improve your overall well-being with these versatile and effective glasses.
