Hi, the lens is still the problem, because it is not easy to find.

I think, I found a good alternative. A small Fresnel lens. Easy to find, cheap and you can cut it with a pair of scissors.

Hopefully I will find the time to test it.

The focal length is about 110mm, with should be fine.

Since we're talking about the lens, why didn't you place the screen right next to the reflector instead of using the mirror? Just asking.

Hello Alain,

I really like your project. It is a great idea creating an own smart glasses. The most other tutorials are about buying a video glasses and modify them, but your project points developers out, how a smart glasses works. I am happy, that I found your project, so I got a knowledge of how it works.

Have you already tried the fresnel lens. Is it working properly?
