Significances: Nowadays refractive errors are one of the most significant causes of visual impairment among different age population throughout the world and also cause of preventable blindness which could be either treated or prevented by known, cost effective means if timely proper eye check-up and necessary steps are taken. So, it is important to do a gender based clinical study about prevalence of refractive errors among both of urban and suburban school going patient in Kolkata region.
Objectives 
    Prevalence of emmetropia vs. ametropia. 
    Prevalence of different types of refractive errors. 
    Influence of gender in different types of refractive errors. 
    Associated diseases connection with refractive media. 
Aim of study: According to VISION 2020 as we know that “Right to Sight” which is the global initiative by both WHO and IAPB for the elimination of avoidable blindness. Aim of vision 2020 to provide a world in which nobody is needlessly visually impaired, where those with unavoidable vision loss can achieve their full potential. To fulfil the aim of vision 2020, at first, we need to know current refractive status scenario among the population at various urban and suburban region worldwide. So, it is necessary to do are view study on the base of prevalence of refractive error among school age, pre-school age, adult and older age people by studies done already on various cities both urban and suburban areas of Kolkata. So that we can make sure about current refractive status scenario of school going children population.
Expected outcome: It is expected from the study that significant amount of population is suffering from refractive errors and it is a leading cause of visual impairment.
