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.

We offer this unique solution in 7 great colors and two sizes – see below

Large size is 5-2/3" x 1-1/2" for wide faces or mm frame optical measurements 56-17-145

Medium size is “5-1/3 x 1-1/2"  for average size faces or mm optical measurement 53-17-140

    Nice glasses for folks who feel....

    Nice glasses for folks who feel cheated when they go to the fancy eye places. These work well. with good optical quality. My only suggestion would be for a little less yellow intensity on the tint option.

    works for me

    Works for me. Perfect for working at my computer. I got the 1.50/2.50. I just wish there was an extra wide option.

    Great but did not work for me. Your milage may vary. Worth a look.

    These are just want I needed post-cataract surgery. The folks here were helpful and shipping was fast. Sadly, the placement of the bifocal insert was just too low for my needs and I found myself looking through the top line much of the time. This will vary by individual so it may work fine for you. It is worth trying out! And the refund was swift and easy! Cheers
