Hello, Welcome to Just Answer
When you say blister does it mean that you have a painful tiny swelling on the eyelid?
Is it on the upper or lower eyelid?
it is not painful but it actually on the eye itself--like a water blister
So it is not on the eyelid but on the white of the eye, right?
Is it raised bubble like on the white of the eye , between the colored part and the inner corner of the eye?
Does it look like this picture- please follow the link to view the picture-http://4.bp.blogspot.com/_ZWqgYBROGHw/TJeN9MOC4aI/AAAAAAAABr4/Rv5CCKDglVU/s400/pinguecula.jpg
It is most likely to be a pinguecula. It is a type of conjunctival degeneration and is a harmless condition and does not lead to any complications.
It does not require any specific treatment but for lubricating eye drops
how long will it last and should I just ignore it?
such as preservative free Refresh tears eye drops , 1 drop 4 times a day. It does not disappear as such and you can as well ignore it . Rarely it may undergo inflammation when it becomes painful and appears red. It responds well to steroid eye drops then.
