Bi-convex Biconvex Lens Set 25mm Diameter 40mm Focal Length for Google Cardboard

These lenses are great. I'm using them for google cardboard and the image is SO clear. If you're trying to find lenses to fit into your cardboard virtual reality headset these are perfect. A low price point had me worried but it's just good business. I'm guessing that the seller shipped them out the same day the order was placed because they were in my mailbox 3 days later. I will absolutely be getting my next set here as well.

These are just what I was looking for. I got them to use on a diy version of the Google cardboard and they fit perfectly. They arrived quickly and not a scratch on them. Very clear image, and great price. Thinking of getting a second pair to make another headset.

These lenses work for their purpose. One came with an imperfection just off center from the middle of the lense. They both were rough where they were cut out. They do work as intended and I can't see the mark on the one lense when using them in my Google Cardboard. The price is reasonable, but I knocked a star off for the general need for a little polishing. Again, they work and I'm happy with the purchase, just know they aren't $30 lenses.

very good lens'.

Great quality, worked perfectly in my application (zoom lens on a pair of safety goggles).

Made my own Google Cardboard. These lenses did a great job and worked great.

Bought to make my own google cardboard, and these lenses worked well.

Fast shipping. Excellent lenses.
