Evaluation of Causes of Visual Impairment Among Bespectacled Between the Age 18-23: A Study from Tamil Nadu, India

Abstract

Visual impairment is internationally related to severe public health, social, and economic challenges. Uncorrected refractive error is one of the main targets of the global movement to end preventable visual disability, as it is a treatable source of vision impairment. With precise information about the prevalence and underlying causes of vision impairment in the general population, health organizations may find it simpler to develop infrastructure and human resource strategies, as well as to distribute resources properly. The design of screening programs to identify individuals who are more vulnerable to eye issues may also be facilitated by having this knowledge. Wearing spectacles, also called glasses, is the practice of wearing frames with lenses in front of the eyes, usually with the intention of improving vision. There are additional reasons to wear glasses, including fashion, eye protection, and concealing visual defects. Even with the rising popularity of contact lenses and refractive surgery, wearing glasses is still the most prevalent technique to correct refractive difficulties. Despite its many built-in advantages, namely the capacity to control usage, spectacles do have some significant disadvantages. Many people who require glasses are unable to afford them, and if they are prescribed incorrectly, they may cause irritation to the eyes. Refractive errors are a major cause of visual impairment worldwide. People who lack professional skills in eye care or dispensing have abused the system due to irregularities in the distribution of spectacles.
