Eyes like being smoked by onions may be caused by visual fatigue and keratitis.
1. Visual fatigue: If patients look at electronic products for a long time or use their eyes at a close distance, the blinking stimulus of the eyes will be reduced, resulting in the appearance of the eyes as if they were smoked by onions, accompanied by symptoms such as dryness of the eyes and loss of visual acuity.
2. Keratitis: When the corneal defense ability of the eyes is weakened, bacteria and viruses attack the corneal tissues, and due to the stimulation of inflammation, the patient’s eyes may feel like being smoked by onions, with photophobia and eyelid spasms.
When the patient’s eyes look like being smoked by onions and do not get relief for a long time, it is recommended to go to the ophthalmology department of the hospital in time for examination and targeted treatment according to the results of the examination.
