Blue-tinted glasses commonly list features such as polarization, full UV protection (UV400), anti-fog coatings, and scratch- or shatter-resistant lens treatments.
Audio-style blue glasses typically advertise up to 10 hours of continuous use from a single fast charge; listings often specify about a 1.5-hour quick charge and note a non-removable lithium battery.
Some blue-tinted glasses advertise durability features such as shatter-resistant lenses and scratch- or anti-fog coatings; water-ready models may include flotation designs, and audio frames often list an IPX4 water-resistance rating.
Many listings use polycarbonate for both frames and shatterproof lenses, while sport models often list TR90 frame material; some sport lenses also use TAC with polarized coatings.
Some blue-lens models integrate open-ear Bluetooth audio with voice-assistant support (Bluetooth 5.2), offer about 10 hours of battery life, include AI translation features, and list IPX4 water resistance.
Blue-tinted lenses—especially when polarized—help reduce glare from reflective surfaces and can enhance contrast and depth perception, which may reduce eye fatigue in bright conditions.
