Ritech 3d glasses, dioptres upgrade

I bought this 3d glasses on Ebay for 17 Euro

I wear glasses, and I cannot wear them together with the Ritech.

Without my glasses the picture is blurry :(

So I had a wired Idear...

I tried it with 2 close up lenses with +8 and 52mm diameter,
normally used for DSLR's

I fixed them inside with hot glue

Positive: 

               -I have now a sharp Picture

               -The picture is now min. 2,5x bigger than before, which is a nice side effect :)

Negative:

               -I am the only person which can now use these glasses.
