Meta Ray-Ban smart glasses are worn daily like regular eyewear, so the practical lifespan is dominated by battery aging and physical durability (hinges, wiring through the temples) rather than just electronics. Common issues include reduced battery runtime, charging/contact problems, camera or microphone failures, and intermittent audio due to flexing and moisture exposure.
Repair is usually only worthwhile when the fix is accessory-based (charging case, nose pads/frames if supported) and cost stays well below the threshold. Replacement becomes the better decision when the internal battery can't hold charge, the hinge wiring fails, or water/sweat intrusion causes intermittent operation-because sealed wearables often aren't economical to service.
Price should be referenced from official Ray-Ban/Meta retail by configuration; lifespan guidance uses general wearable durability expectations.
