I wear glasses too and I had trouble seeing out of it. I could only really see out of it if I had my contacts in.  

The filter is made out of the Professional Optical Glasses, and multiple layer nanometer coating 

hello,the new version of this ND filter is double-side multilayer blue coating 

I had the same question as you. I was reading on their website about this filter (ND8-ND2000) because I didn't understand if this filter is 9 stops why it has 11 marks plus 3 others marks for wide angle. So I found that the filter has to additional stops. The order is: nd8, 16, 32, 64, 100, 128, 256, 400, 512, 1024 or 1000, and 2048 or 2000 plus the other 3. So you should check if maybe you are not in the stop you are thinking. Maybe I'm wrong, but has been what I've found...I haven't use it because I just received it today. 

Yes, you can use the binoculars while wearing glasses!
