Higher-energy, shorter wavelengths — the ones most associated with digital eye fatigue — are blocked at higher rates, while lower-energy blue light that can affect your circadian rhythm is filtered at lower levels, helping you stay comfortable during extended screen sessions.\u003c\/p\u003e\n\u003ch4\u003eQ: Are these glasses suitable for both gaming and everyday computer use?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. The VOPHA S71 blue light blocking glasses are designed with a unisex classic square frame that works equally well for intense gaming, office work, or general screen time. The retainer strap adds extra security for active gaming, while the stylish acetate frame makes them appropriate for everyday wear.\u003c\/p\u003e\n\u003ch4\u003eQ: Do these glasses require a prescription to wear?\u003c\/h4\u003e\n\u003cp\u003eA: No, the VOPHA S71 glasses are non-prescription, zero-magnification lenses. They are designed purely for blue light filtering and are ready to wear straight out of the box without any prescription needed.\u003c\/p\u003e\n\u003ch4\u003eQ: How durable are the polycarbonate lenses?\u003c\/h4\u003e\n\u003cp\u003eA: Polycarbonate is one of the most impact-resistant lens materials available, making the VOPHA S71 lenses highly durable and scratch-resistant for everyday use.
