We bought two of these 3D glasses for our Sony televisions. A small charge is already the supply of spectacles available so that you can already test. After fully charged keeping the glasses for longer by (movies like the hobbit no problem). I as eyeglass wearers have to wear no problems this 3D glasses over my actual visual aid. Neither I nor my partner feels printing after extended wear or other phenomena. The effects come across well and the viewing angle is also very large. We can recommend these glasses.
