Bewertungen zu Blue Light Blocking Glasses – Universal Fitover Series

Description Blue Light Protection That Fits Over the Glasses You Already Wear If you wear prescription glasses or readers, most blue light blocking glasses force you to choose: blue light protection or vision correction. The DefenderShield® Universal Fitover Blue Light Glasses eliminate that trade-off. The wide, rectangular TR90 frames are engineered to sit comfortably on top of your existing glasses, adding a blue light filtering layer without replacing the lenses you depend on for clear vision. Two lens options target two different use cases: Amber (50% blue light filtering) - designed for daytime and all-day use. The slight amber tint preserves natural color perception while reducing the blue light reaching your eyes during work, browsing, and general screen time. Orange (99% blue light filtering) - designed for nighttime use and maximum blue light reduction. The deeper orange tint filters nearly all blue light, supporting the body’s natural transition toward sleep. Ideal for evening screen sessions, gaming, and use within 2–3 hours before bed. Lightweight and Flexible The frames are made from TR90 - a thermoplastic nylon used in sport and medical eyewear for its combination of low weight, high flexibility, and durability. TR90 is lighter and more flexible than standard acetate, which matters when you are stacking one pair of glasses on top of another. The fitover frame is deliberately kept lightweight to minimize added bulk and maintain comfort during extended wear. The lenses are CR-39 - a shatterproof optical plastic used in prescription eyewear. Three coatings are applied: Anti-glare - reduces reflections from the front and back surfaces of the lens. Anti-smudge - resists fingerprints and oils for clearer vision throughout the day. Anti-fatigue - improves screen contrast and readability of small text. Key Features 👓 Fits Over Prescription and Reading Glasses The wide rectangular TR90 frame is designed to sit comfortably on top of most standard prescription and reading glasses. No need to choose between vision correction and blue light protection - wear both at the same time. 🟡 Amber Lens - 50% Blue Light Filtering for Daytime Use A slight amber tint that looks close to clear. Reduces blue light by half while preserving natural color perception. Best for office work, browsing, video calls, and general daytime screen time. Also brightens vision while driving in overcast or rainy conditions. 🟠 Orange Lens - 99% Blue Light Filtering for Night Use A deeper orange tint that filters nearly all blue light reaching your eyes. Designed for the 2–3 hours before sleep when blue light has the strongest effect on melatonin production and circadian rhythm. Ideal for gaming, streaming, and late-night work. 🦴 TR90 Frames - Lighter and More Flexible Than Acetate TR90 is a thermoplastic nylon used in sport and medical eyewear. It weighs less than acetate and flexes without breaking, which is especially important for a fitover frame that needs to accommodate the shape and width of the glasses underneath. Durable enough for daily use, light enough to forget you are wearing a second pair. 😴 Sleep Support Through Blue Light Reduction Blue light from screens suppresses melatonin and disrupts the circadian rhythm. The Orange (99%) lens filters the wavelengths that interfere with the body’s evening wind-down, helping you fall asleep faster and supporting deeper rest - without removing your prescription glasses to do it. 💠 CR-39 Shatterproof Lenses with Three Coatings The same optical-grade plastic used in prescription eyewear - lightweight and impact-resistant. Anti-glare, anti-smudge, and anti-fatigue coatings reduce reflections, resist fingerprints, and improve text readability on screens. How to use Wearing the Fitovers 1. Put on your prescription or reading glasses as normal. 2. Place the Fitover glasses on top. The wide rectangular frame should sit comfortably around your existing glasses without pressing on them. The temples of both pairs run parallel along the sides of your head. 3. Adjust for comfort. If the fitovers feel too snug, gently flex the TR90 temples outward - the material is designed to bend without breaking. If they feel too loose, the flexible frame will still grip gently enough to hold position during normal use. Choosing Your Lens • Amber (50%) for daytime. Colors remain close to natural.
