    Perfect for 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.

    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
