I got a new contact lenses, but i can't tell which lense is the right one. I mean, It doesn't say what's the right eye and what's the left eye one. WHAT DO TO?? What if I used them, not knowing which one is which? Will my eyes get damaged? Plus, I don't even know what's the correct side to wear. it's a clear lense, not coloured one! PLS HELP!!!!!!

Once you've taken the lenses out of their blister pack or vials, there is no way to tell which is which. That is why you should never take both of your caps off of your case at the same time. Sometimes if your eyes are different, but close in prescription, it can be really tricky to tell if you have switched them. When in doubt, you'll have to throw them out and start over with a new pair.

Patients who wear RGP lenses have the option to have a dot placed on the right one to keep them straight. Can't do that with soft lenses though, unfortunately. Sorry!

How can I tell which contact lens is left and right if I think I mixed them up? (They have prisms and are to last for a year.)
This can be tricky. If your eyes are very different, I would insert the right and check the vision. If it's clear you might have the correct lens. The reverse if blurry.
If they are very similar and you can't tell the difference then no harm done.
I assume you mean Toric (astigmatic) when referring to prisms. The ballast prism is used to guide the lens into its proper orientation.
Yearly lenses are not common these days, where did you get fit?

Contact the optometrist who supplied them. If they are rigid lenses, (gas permeable) they may be marked R and L. If they are soft lenses, you may have to revisit the optometrist, UNLESS… there is a big difference between the prescription of the lenses, in which case, try them both ways. When you get best vision is when they are the right way round.

You should have had one of those little cases that holds them in solution. Never mix up your contacts! Always put the right one in the right side and the left in the other. You should be able to tell if it doesnt look right but ALWAYS keep them distinguished by the container. If you dont even know what side to wear it then you've got major issues, didnt you have an orientation about contacts where they give you info and show you how to use them!? Talk to your eye doctor, maybe they can sort it out. Just wear glasses for awhile then.
