失明 (shī míng): สูญเสียสายตา

That car accident left him blind in both eyes, but he didn't give up on life; he began learning Braille and later even opened a massage shop.

As he grew older, Grandpa's eyesight got worse and worse, and the doctor warned that without timely treatment, he could lose his sight.

If treatment for this rare eye disease is delayed, it will eventually lead to blindness, so you must go to the hospital for a checkup as early as possible.

Because his diabetes was poorly controlled, his retina was damaged, and the doctor told him that if things continued this way, he would likely go blind.
