The Zera Multi Focus™ Reader has three different strengths that allow you to use them for reading, computer use, and interacting. The magnification is strongest on the bottom of the lens (what you use for reading), the middle portion is slightly less than your reading power, and the top portion of the lens is half of your reading power. The Zera is a convenient, cat eye frame that has scratch-resistant lenses, an anti-reflective lens coating, and spring hinges for a comfortable fit. This pair comes with the case and cleaning cloth pictured for easy storage and protection. Shop our entire Multi Focus™ by Foster Grant® collection here. You may notice that the anti-reflective lens coating adds a subtle tint of color to the lenses.
