Dual Strength Bifocal- The Card Shark

I would give these a 5 star rating except for one thing, and it's no ones fault. I need a 1.5 on top and a 2.75 on bottom, but no one seems to make that. So I got a 1.5 on top and a 2.5 on bottom, and unfortunately the .5 difference is very noticeable. Otherwise I really love these glasses. They're stylish and well made. Shipping was earlier than expected and the case included is great. If I can ever find someone to do a 1.5/2.75 I will gladly give them 5+ stars.

I think if more people knew about these they would love them. They help my computer and also my paperwork become clear. I use a lower strength on the top and higher on lower and it works wonderfully

I’m an electrical engineer and spend much of my time switching my gaze between a large monitor and reading material on my desk, and since I am far-sighted, this means switching between two different strength reading glasses. For quite some time now I’ve looked for readers with different magnifications to no avail. I’ve tried “progressives” which have a very small field of view (an extreme case of foveated view), and can not tolerate this. I don’t remember how I stumbled on these card sharks, but I’m very glad I did; these are worth their weight in gold to me; no more swapping glasses repeatedly. Quality is fantastic as well. Good job Debbie Burke!!

I spend a lot of time on computer while doing paperwork, Dual strength bifocals allowed me to stop having to switch glasses each time i went from cpu screen to paper documents. Great product that met my needs.

I am constantly struggling with the need for 2 different OTC readers. One for close up and one for my computer. My optometrist could only supply these with plain glass at the top and the 2 reading powers sharing the bottom half of the frame. Gave me headaches as the area I had to focus on was very thin. After much searching I found these. The Card Shark Dual Strength Bifocal is perfect. Top half is for reading my computer, the bottom half is for papers or phone or similar. So glad I found them. No more carrying around multiple reading glasses. the lens is of good quality, the frames are solid and the wider frame fits me head perfectly not leaaving me with imprints along my temple. These are a must have is you want simples dual power readers.

These glasses are great!! They provide a clear vision for both powers. The quality is excellent.
