People can extend their healthy years by taking steps to prevent health problems. Instead of concentrating on personal health, it is varied and considers the health of the entire population. In the case of a pandemic, the public may span many continents and can range in size from a few individuals to a whole town or city. The idea of health encompasses mental, emotional, and social wellbeing. As a result, it is not just the absence of illness or disability, and more recently, it is a resource for daily life, according to the World Health Organization.

Public health is crucial because it increases and prolongs life. Over 100 people have benefited from the introduction of eye examination clinics by Pratima Foundation Trust in addition to the health centres. Many people have had their cataracts repaired in conjunction with affiliated hospitals.
