The RX-75, Lighted MagRX™ is a 3x power, clip-on magnifier designed to fit on most standard prescription bottles. Simply clip the magnifier to a prescription bottle and swing the magnifying lens outward to magnify text. Two ultra-bright LED lights on the Lighted MagRX™ illuminate the prescription label. The 3x power magnification will help avoid mistakes in reading vital dosage or instructional information listed in difficult to read fine print. Fold the magnifying lens on the Lighted MagRX™ inward against bottle when not in use for compact, easy storage. Three button cell batteries included.
