The IOA was formed in the early 1950’s as an educational body to upgrade the knowledge of Indian optometrists. It is one of the only associations that is not affiliated with any other society or association. The IOA aims at getting complete information on these new brands, methodologies and techniques that are introduced in the market so as to enable the association to spread awareness of the products and correct usage.

NSO is member with IOA and is been facilitated for development in the field of optometry.
