Are My glasses Ok ?

Here are my glasses : Attachment 790

I have seen Kasina videos and in the Videos the glasses are different . The glasses work fine , but the green led is covered but the plastic protector and It lose brightness because of this .

No that is not correct. The mounting has shifted either in packing or transit. The diffuser is mounted with double sided tape. You can easily move it back into position (like the one on the right) and it should remain in place. I have removed diffusers and put them back on with no loss of adhesion, so the glue on the diffusers is robust.

My Kasina glasses were delivered in the same condition, left diffuser askew. As Scott says, it is easy to remove it and replace it in the correct position. Mine has stayed put for four months with no tendency to loosen or shift position.

Thanks you .
