A 17-year-old British man has lost his eyesight because of his addiction to fried potato chips due to a severe vitamin deficiency in his diet.

According to the Daily Mail, the young man living in Bristol has not eaten any fruits or vegetables for 15 years, but only fried sausages and chips.

The young man's eyesight began to slowly weaken the lack of vitamin B, vitamin D and copper in his diet, which made him have to drop out of college.

For three years, the young man lost his eyesight after suffering a condition called "optic neuropathy," which is caused by a lack of vital nutrients.

The young man expressed great sadness, commenting on his condition, saying that he loved playing with his friends a lot, but now he can no longer do any activity and has become isolated.
