Premium Materials for Screen Time Comfort
Our Essential collection features three trusted materials chosen for their durability and wearability. The acetate frames offer rich color depth and reliable flexibility, while our TR90 rubber frames provide ultra-lightweight comfort—the same material used in aerospace engineering. For those preferring minimalist elegance, our stainless steel options deliver sleek, hypoallergenic frames that resist corrosion. Each pair protects against digital eye strain while the +2.5 lenses help you see screens and documents clearly. Explore our round blue light glasses with +2.5 strength or rectangular blue light glasses with +2.5 strength for alternative shapes.
Why Square Frames Work for Digital Life
Square frames provide a balanced, contemporary look that complements most face shapes, especially those with softer, rounded features. The defined angles create structure and confidence, making them ideal for video calls and professional settings. Unlike traditional reading glasses, these frames include blue light filtering technology to reduce eye fatigue, improve sleep quality, and minimize headaches from prolonged screen exposure. Available without prescription as non-prescription square blue light glasses, or browse our square reading glasses with +2.5 strength if you don't need blue light protection. For outdoor protection with the same prescription, check out our square sunglasses with +2.5 strength.
Frequently Asked Questions
What is the difference between blue light glasses and regular reading glasses?
Blue light glasses feature a special lens coating that filters 30-40% of blue light emitted by digital screens, while reading glasses only provide magnification. Our +2.5 blue light glasses combine both benefits, helping you see clearly while reducing digital eye strain, sleep disruption, and headaches from prolonged screen time.
How do I know if +2.5 is the right strength for me?
If you're around 50-55 years old and struggle to read text on screens or documents at arm's length, +2.5 is often suitable. Our free online vision test provides instant results to help you determine your ideal lens strength without visiting an optician.
Will square frames suit my face shape?
Square frames work beautifully for round, oval, and heart-shaped faces by adding definition and balance. If you're unsure, our personalized style guide helps you discover which frame shapes complement your features best, or see how they look on you with our virtual try-on feature.
What materials are these glasses made from?
This collection includes frames crafted from durable acetate for vibrant colors and flexibility, ultra-lightweight TR90 rubber used in aerospace applications, and hypoallergenic stainless steel for a refined, minimalist aesthetic. All materials are optician-grade quality typically found in glasses costing significantly more, and they're built to withstand daily wear.
Can I wear these glasses all day?
Yes, these glasses are designed for extended wear during screen time and close-up tasks. The blue light filtering helps reduce fatigue during long work sessions, while the +2.5 magnification supports comfortable reading and device use. However, they're optimized for near vision, so you may prefer to remove them for distance viewing.
