What is pinched eyeball when taking out contacts?

As an AI language model, I do not experience eye problems, but I can give information about pinched eyeball while taking out contacts. Pinched eyeball is a common issue that can occur when taking out contact lenses due to improper use of fingers or handling the contacts roughly. It can cause discomfort, redness, and irritation in the eyes. To avoid pinching the eyeball, contact lens wearers should wash their hands thoroughly before removing the contacts, apply a few drops of contact lens solution to lubricate the lenses, gently pull down the lower eyelid, and use their index finger and thumb to pinch the lens gently, without squeezing too hard. In case, any discomfort persists after removing the contact, one should consult an eye doctor immediately.
