The presence of white spots inside the lower eyelid is seen in conjunctival calculi, a very common disease in ophthalmology, usually due to unreasonable eye habits or the presence of chronic conjunctivitis in the eye, and, therefore, leads to the deposition of lipids and calcification under the conjunctiva, forming white or yellow-white granular material and causing a distinct foreign body sensation in the eye. In this case, it is recommended that first of all, local anti-inflammatory treatment can be given to control chronic conjunctival inflammation and most conjunctival stones can be discharged on their own with time. If the conjunctival stones remain under the conjunctiva for a long time and cause significant foreign body sensation, you may also consider going to the hospital to have the conjunctival stones picked out from under the conjunctiva by an ophthalmologist under a slit lamp, which can also effectively reduce the foreign body sensation in the eyes. It is important to maintain reasonable eye habits so that conjunctival stones can be effectively avoided.
