While burning your eyes is a symptom of an eye condition (conjunctivitis) during diabetes, it is not the sole cause of your eyes burning. In diabetic patients, reduced tear secretion due to prolonged duration can lead to burning, discomfort, and stinging of the eyes, accompanied by redness, discharge, and eyelid stickiness. During diabetes, the body experiences inflammation due to high blood sugar, which hinders the lacrimal glands' ability to produce tears, resulting in dryness and eye pain.
