Small bubbles under the eyelashes are usually caused by prolonged late nights, poor rest, and irregularities in life that lead to blockage of the eyelid gland, where the oil-like substances secreted by the eyelid gland cannot be discharged normally and form small bubbles at the mouth of the gland. In this case, it is important to take more rest and eat a light diet with more green leaves and vegetables and less oily, spicy and stimulating foods to help the bubbles absorb. If this bubble is not absorbed for a long time, resulting in a significant foreign body feeling inside the eye, you can go to the hospital with a sterile syringe needle to puncture the small bubble, apply anti-inflammatory eye ointment, point anti-inflammatory drops, to be able to cure as soon as possible.
