If you feel something sticking in the corner of your eye, the first thing to check is whether you have an ingrown eyelash or whether your eyelashes are turning inward and sticking to your eyeball. If there is such a phenomenon, you need to remove the ingrown eyelashes and you will be able to relieve the symptoms. If the inner part of the eyelid is fixed and there is a feeling of zapping or foreign body sensation, it may be a conjunctival stone, so you need to go to the hospital to pick out the stone, and the zapping and foreign body sensation can be relieved. In other cases, if the lacrimation or foreign body sensation is diffuse and occurs occasionally, it is usually caused by dry eyes or eye fatigue.
