Why when i look through a binocular microscope i see double?

[kal r]

Whenever I look through a microscope I have trouble looking through both eye pieces at the same time ( we use binocular microscopes.) I wear contact lenses and have no problem seeing normally when not looking through a microscope. What do I do to resolve this? I am taking cellular biology, microbiology, and ecology so it is crucial that I can use the microscope effectively.

Thanks for your time and help, I greatly appreciate it.
Yeah I will try the cross eyed technique. I'll also ask one of my professors or T.A's...
I also use one eye to see usually to close one eye.

I thought i was going to have something horrible like Strabismus or something but from what my sister can tell and my mom it appears im not cross eyed or anything...what could be doing this damnit! lol..thanks ppl..atleast i dont feel alone anymore...if anyone else has any ideas please let me know

This happens to me to, but I don't wear contacts. Generally, the only way I can fix it is by closing one eye, but that isn't really the best thing to do, I'm sure. I have found that sometimes if I go slightly cross eyed I can also solve the problem! Hope you find something that works for you!

When using any kind of magnified bino-viewer, a VERY SLIGHT mis-alignment (mis-collimation) can manifest itself as pretty bad double imaging at high powers - and the higher the powers, the greater the effect.

Maybe the optical axes of your two contact lenses aren't perfectly aligned with each other...
Try using the microscope without your contacts in, and see if that cures it.

Also - make sure the IPD (inter-pupillary distance) of the bino-viewer is set correctly for you.
