Ultra-clear mobile phone screen magnifier with optical HD zoom delivers 3 to 4x magnification to reduce eye strain from small screens during long viewing sessions. Key benefits - Clear, enlarged viewing: optical HD zoom magnifies content by 3 to 4 times, making it easier to watch videos, read text, and view images without squinting. - Eye fatigue reduction: enlarging the on-screen image helps minimize visual fatigue during extended use. - Secure, anti-slip design: built with ABS housing and an acrylic lens, the anti-slip structure helps keep your phone steady while you view. - Note on image quality: the magnifier reduces the overall display resolution compared with direct viewing; for best results use in low light with a viewing distance of about 1.5 meters.
