Yellow patches in the eyes may be caused by inverted eyelashes, chalazion and blepharospasm. 1. Inverted eyelashes: due to the abnormal growth of eyelashes, inverted to the eyeball, resulting in friction and irritation of foreign objects in the eye, causing eye pain, redness, swelling, increased secretion, etc. If there is oozing of small blood vessels, yellow patches in the eyes may occur. 2. Chalazion: Because when the blepharoplasty gland secretes exuberantly or the epithelial cell proliferates and hypertrophies, a large amount of secretion will accumulate in the local tissues, resulting in congestion, redness and swelling of the eyelids, which will lead to the condition of yellow patches in the eyes. 3. Blepharoplakia: If long-term exposure to ultraviolet light, smoke, dust, chemical stimulation, it will make the bulbar conjunctiva near the cornea appear slightly elevated plaque, which can be grayish-white at first, and then develop into yellow plaque. Patients who have yellow patches in the eyes should go to the hospital in time for relevant examinations, and the doctor will give the correct treatment according to the examination results.
