Two Strength Bifocal Reading Glasses
Dual Bifocal Reading Glasses: Two Strengths for Computer and Close-Up Reading
People usually find Dual Bifocal reading glasses for one of two reasons. Progressive readers never felt natural, leaving them searching for the right viewing zone. Or they already use one pair of reading glasses for the computer and another stronger pair for close-up work—and are tired of switching between them all day. Dual Bifocals solve both problems by putting two customized strengths into one pair. What are Dual Bifocal reading glasses? They are two-strength reading glasses with two clearly defined magnification zones in each lens. The upper portion uses a lighter power for computer and intermediate viewing, while the lower segment uses a stronger power for reading, paperwork, phones, and other close-up tasks. Unlike progressive lenses, the powers do not blend through a progressive corridor. You look through one defined strength or the other depending on what you need to see. Your upper and lower powers are customizable, allowing the lenses to be built around the strengths you use for intermediate and near vision. Instead of keeping separate computer glasses and reading glasses nearby, you can move from screen to page without changing frames. Dual Bifocals are designed for computer-distance, intermediate, and close-up viewing. They are not intended to replace full-distance prescription correction. For more than 30 years, Debby Burk Optical has specialized in reading-glass solutions standard retailers often overlook. Working with experienced opticians, we developed our customized Dual Bifocal readers as a practical middle ground between single-strength readers and progressives. If you need reading glasses for computer and close-up work, regularly switch between two strengths, or have struggled to adapt to progressive readers, Dual Bifocals offer another way to solve the problem. Two customized strengths. One pair. Switch tasks—not glasses.
