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.

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.
