Nitrituria is a presence of nitrites in urine. Nitrites are formed from the chemical conversion of nitrates by bacteria. Eyes are
optical complexed system and are a major organ of a human body. Any abnormality in this organ may lead to very serious conditions.
Myopia is characterized by a refractory disorder in which eye is not able to focus light onto the retina. The objective of the present
study is to check the association of nitrates in urine with eyesight. 100 participants accepted to take part in this project. Urinalysis

Multan. In 18% male and 39% female respondents with eyesight between 0 to -1 dioptre(D), normal results were observed. The
research concludes that there is no relation between eyesight and urine nitrites [1-3].
