Details

Many people find that their normal readers are too strong when they look at their computer because it's easier to focus on farther objects. However, most over-the-counter bifocals on the market today have zero power on top. So, DebSpecs worked with partner opticians and lab techs to develop a high quality dual power bifocal. These dual power bifocal lenses have power on both the top and the bottom.

These are lined bifocal lenses and feature high end optical cr39 material, weaker power on top with your usual reading power located on the bottom. A classic rectangular eyeglass frame, offered with incredible colors, and high quality tr90 flexible yet resilient plastic.

Most customers have an idea what they need, however, if you are uncertain, you can try the eye chart, but we recommend you try it twice.

  • First, make sure the chart is 5" wide.
  • Read it at 14", or the distance you read close up materials, which will estimate the bifocal portion.
  • Then read it at the distance you normally view your computer, which will estimate the upper lens.

Use these measurements to select your top and bottom strengths.
