The causes of itchy lower eyelids are as follows.
If the lower eyelid itches and is accompanied by significant redness and swelling, consider contact dermatitis, in which the patient may be exposed to poor quality cosmetics, allergy medications, irritating objects, etc. causing allergies.
If there is a tender lump on the lower eyelid when touched, it may be blepharitis caused by bacterial infection. Early onset eyelid redness and swelling is not obvious, and some patients may show itchy and congested eyelids.
