Established since 1986, at Ahmedabad (Gujarat), We “Ajmera Optics” are chasma manufacturing by latest technology with biggest show room in Maninagar. Our association is efficiently managed by our founder, Mr. Kamlesh Murjibhai Ajmera, who holds huge experience and knowledge in this domain.
When it comes to eye care, we believe there is no room for error. No, make that absolutely no room for error. That’s why we make it a point to use technology to get things right, right down to the most infinitesimal degree with the most advanced computerized, refractometre vision testing. What does a refractometre have to do with eye care? A refractometre is a laboratory or field device for the measurement of an index of refraction (refractometry).
Autorefractor
An autorefractor or automated refractor is a computer-controlled machine used during an eye examination to provide an objective measurement of a person’s refractive error and prescription for glasses or contact lenses.
What does Vijaya Optical House do for you with the world’s best autorefractor?
Using equipment that sets new benchmark in this regard, we focus on providing comfortable and accurate eye care at all stages. The compact and contemporary equipment we use goes a long way in enhancing the quality of treatment that can be provided to you.
Refraction Test
A refraction test is usually given as part of a routine eye examination. It may also be called a vision test. This test tells your eye doctor exactly what prescription you need in your glasses or contact lenses. This is achieved by measuring how light is changed as it enters a person’s eye.
The Technique
The majority of autorefractors calculate the vision correction a patient needs (refraction) by using sensors that detect the reflections from a cone of infrared light. These reflections are used to determine the size and shape of a ring at the back of the eye called the retina. By measuring this zone, the autorefractor can determine when a patient’s eye properly focuses an image. The instrument changes its magnification until the image comes into focus. The process is repeated in at least three meridians of the eye and theautorefractor calculates the refraction of the eye, sphere, cylinder and axis. Modern autorefractors are based on the idea patented by Medina.
