Swollen eye blisters can be determined by two common methods: visual observation or slit lamp examination. Naked eye observation, that is, through naked eye observation of the patient’s eye morphology, to see whether the patient’s eye occurs in the upper eyelid of the swelling, you can determine whether the patient is a swollen eye blister. In addition to this, clinical judgment can also be made through slit lamp examination. The slit lamp can check the problems related to the corneal conjunctiva, eyelids, eyelashes and the opening of the blepharoplasty to see if there are inflammation, trauma and other conditions that lead to swollen eye blisters. If you feel that you have swollen eyes that affect your appearance or are accompanied by other discomfort such as eye pain, it is recommended that you seek medical attention as soon as possible and follow your doctor’s instructions.
