What is Visual Acuity/Visiometry

Visual acuity is the ability of our visual system to distinguish details clearly at a given distance and under certain conditions. Therefore, it indicates the possibility of seeing details of an object on a uniform background or of seeing that two very close objects are, effectively, separated. ​
The measurement of visual acuity is a test that is essential in any visual examination since it tells us exactly the vision that the patient has and, if it is diminished, it can show the existence of some ocular pathology such as cataracts, macular degeneration associated with age (AMD) or diabetic retinopathy, among others.

Snellen test

Visual acuity is measured by optotypes that the patient has to identify, both in distant vision and reading in near vision. The best known optotype is the Snellen test, which consists of rows of letters or numbers that go from larger to smaller in size. The last row that a patient can read correctly determines their visual acuity and is described as a decimal value (1.0) or as a percentage (100%).


Computerized test

We perform a complete visual examination in a minimum time. We examine you under a variety of conditions, including monocular, binocular, near, far, and intermediate. Peripheral vision test. Visual acuity tests in adults and pediatrics, color and depth perception, as well as vertical and lateral phoria.
