First of all, you need to work out if they are eyelash extensions or false eyelashes, because then you can work out what sort of adhesive has been used and how you can get it off.
If they are eyelash extensions, you will have paid in excess of fifty pounds for them, the procedure to apply them will have taken in excess of an hour, and there will be one individual eyelash extension (much like your own natural lashes) on approx 30 of your own eyelashes.
If they are false eyelashes, you will have paid much less than fifty pounds, the procedure will have taken about half an hour (depending on how many lashes were applied) and the lashes will appear in a cluster, knotted to a noticeable bulb which will be slotted in between your natural lashes, and will more than likely be touching your skin.
I am guessing you have the latter, false eyelashes, as certain adhesives used to apply these can be very irritating to the eye. The adhesive used for eyelash extensions is medical grade adhesive that does not often cause an allergic reaction and, if the procedure has been carried out correctly, should not be touching your skin.
To remove false eyelashes, an oil based eye makeup remover will get them off easily. For eyelash extensions, you will have to find your nearest salon and have them removed professionally.
