This handheld magnifier has been designed with simplicity in mind. Its top mount thumb rest promotes a more natural hand position creating balanced weight distribution between lens and handle. The 2x to 4.5x bifocal lens and lightweight design is perfect for extended reading times or for those with limited strength. The 4.5x spot lens is molded in to the crystal-clear acrylic primary lens for ease of use and seamless focusing transitions. Protected by a full rim, this magnifier is the perfect accompaniment for around the house.
