How Does an Eye Doctor Test for Low Vision?  

Low vision is defined as a retention of vision coupled with a loss of acuity. Low vision assessments are usually conducted by an optometrist or ophthalmologist with the goal of understanding how low vision is impacting the person’s day-to-day life. Unlike the standard Snell test (also known as a letter eye chart), though, your doctor will likely use a logarithm of the minimum angle of resolution (LogMAR) to determine the next steps.

What Is a LogMAR Chart?

A LogMar chart may look somewhat familiar to a patient who’s used to seeing the standard Snell chart (commonly defined by the large E on the top row). The difference is that it was developed in the 1970s to test more for acuity than for vision. The eye doctor is essentially trying to see how well you can discern certain details and then measuring them against a base-10 scale. There are typically five letters in each line to ensure that they have enough data to work with.
