Blue Light Glasses

The science is mixed. Blue-light glasses block a portion of the high-energy visible light from screens, which some users report reduces eye strain and improves sleep when worn in the hours before bed. Large clinical studies have not found a clear benefit for daytime eye strain or long-term eye health. If you find them helpful, wear them; if not, regular screen breaks (the 20-20-20 rule — every 20 minutes look 20 feet away for 20 seconds) is the most evidence-backed approach.

No — Quince blue light glasses ship as non-prescription, clear-lens eyewear. If you already wear prescription glasses, you would need to add blue-light filtering at the lens-coating level through your optometrist, or wear blue-light glasses over contacts. Quince does not currently offer prescription lens fulfillment on these frames.

Reading glasses use magnification (typically +1.00 to +3.00) to help with close-up vision; blue light glasses have a clear, non-magnifying lens with a blue-light filter. Reading glasses help you see the screen if your near vision has changed; blue light glasses theoretically reduce eye strain from screen use regardless of vision. The two are complementary, not substitutes — some people wear both.

Quince sunglasses use Italian acetate frames — a plant-based plastic derived from cotton and wood pulp that holds rich color, polishes smooth, and feels warmer and lighter on the face than petroleum-based plastic. Acetate is hand-polished, hypoallergenic, and durable enough for daily wear. Hinges are stainless steel with five-barrel construction for smooth opening over years of use.

Most users wear blue light glasses during long screen sessions — computer work, gaming, extended phone scrolling, or any time you've been on screens for 2+ hours. Wearing them in the evening (after sunset) may also support natural sleep cycles, since blue light suppresses melatonin production. They are not necessary for short screen sessions or non-screen daily activities.

Sunglass fit is mostly about frame width — the distance across the front of the frames should match your face width (measured temple to temple). Each Quince product page lists frame width (typically 130-150mm), lens width, bridge width, and arm length. As a general rule: 130-138mm fits narrow faces, 138-145mm fits average faces, 145mm+ fits wider faces. The arms should curve gently over the ears without pinching.
