Blindness and Visual Impairment are the major social issues which can set back a country’s development and cause major hindrance in our society development process. Cataract and refractive error are the major causes of blindness in our society and early detection and proper treatment of both this condition (surgical and optical) can help patients to get back their vision lost by these conditions.

National Program for Control of Blindness launched by Govt of India to stop a patient to go unnecessary blind has emphasized to undergo timely cataract operation services and distributing free glasses to people in need to stop a person form going visually handicapped. Although the number of patient going blind due to cataract has gone down in the past few decades but still it remains one of the important causes of blindness in our society. Uncorrected Refractive Error remains the second most important causes for blindness in India as there are lack of qualified optometrist to screen, diagnose and identify the reasons of not wearing spectacles among young school going children.

Optometrist are  primary eye health care professional who diagnose and treat different refractive error and prescribe glasses specially to young school children who are in need of spectacle , as we all know that major vision develops happens until the age of 6 years , so if a child is not wearing  his prescription in the first 6 year his vision development will not be complete and it could cause severe problem in visual system which can cause severe hindrance in his/her academic and personal career.  Glasses are also an important optical device to give 100 percent vision after cataract surgery and optometrist are specialized to prescribe and dispense spectacle in all age group in both rural and urban population.

There are only 42,000 primary eye care professional out of population of 140 corer population, definitely is not enough to screen entire population of all age groups, so in India there is huge demand of optometrist both in private and government sector in upcoming years and decade to give quality eye care services who are in need of it.

Optometry has several branches which provide various eye health care facilities to various section of our society for providing quality eye care services and eradicating blindness in our society.

There are many types of squint one major reasons of squint is uncorrected refractive error, if a child is not wearing his/her prescription for longer period of time specially during the critical period of vision development there is high chance of developing squint and it can be corrected by continuous wearing of spectacles and vision therapy treatment.
4. Low Vision: Low Vision patients are those who after rigorous medical and surgical treatment their vision cannot be restored to normal vision, these patients need special attention through various optical and non-optical intervention these treatment procedure is often described as low vision treatment and rehabilitation.
