Square Blue Light Glasses with +3.5 Reading Strength
Discover our collection of 30 square blue light glasses with +3.5 reading strength, expertly designed for everyone who needs both digital eye protection and close-up clarity. These versatile frames combine the clean, contemporary lines of square blue light glasses with precisely calibrated reading lenses, making them perfect for anyone over 40 who spends time on screens while reading, working, or enjoying hobbies. Crafted from premium materials including durable acetate, flexible TR90 rubber, and sleek stainless steel—materials typically found in glasses costing 2-5x more—our Essential collection delivers optician-grade quality at honest prices.
Advanced Screen Protection Meets Reading Clarity
Each pair features specialized blue light filtering lenses that reduce digital eye strain during extended screen time, while the +3.5 magnification provides crystal-clear vision for reading fine print, reviewing documents, or working on detailed tasks. Whether you're switching between your computer and paperwork or scrolling through your tablet before bed, these frames offer seamless visual comfort throughout your day. Looking for the same protection without magnification? Explore our complete +3.5 strength collection or discover other rectangular and round blue light options in this strength.
Universal Style in Premium Materials
Square frames offer a universally flattering shape that suits all face types with their balanced proportions and modern aesthetic. Our collection features frames in lightweight TR90 rubber—a super lightweight material that is often used to make airplane parts, made by swiss technology—flexible acetate construction, and hypoallergenic stainless steel designs. With options ranging from classic black and sophisticated tortoiseshell to contemporary crystal grey and warm olive tones, you'll find frames that complement your personal style. Trusted by over 150,000 customers, these frames are available with our 3-for-2 offer, making it easy to keep pairs at home, work, and in your bag. If you also need outdoor protection, browse our square prescription sunglasses or consider pairing with traditional square reading glasses for screen-free reading.

Take our personalized style guide to discover which specific styles suit you best.
Can I wear these blue light glasses all day?
Absolutely. These glasses are designed for extended wear throughout your day, whether you're working at a computer, reading emails, or browsing on your tablet. The blue light filtering helps reduce eye strain and supports better sleep quality by blocking the harsh blue wavelengths from screens. The +3.5 magnification makes them ideal for close-up work and reading.
What's the difference between acetate, rubber, and stainless steel frames?
Acetate frames offer durability and rich color options with a classic feel. TR90 rubber frames are incredibly lightweight and flexible—the same material used in airplane parts, crafted with Swiss technology—making them virtually unbreakable. Stainless steel frames provide a sleek, modern aesthetic with hypoallergenic properties, perfect for those with sensitive skin. All three materials deliver premium quality and long-lasting comfort.
