Locum Optometrist

Easy access makes it also ideal for the locum optometrists who wants to have a more complete suit of charts (e.g. binocular vision or logMAR VA) at their disposal from their phone, tablet, or laptop.

Also, the Interactive Case History can prove a useful tool to remind of essential key questions for a thorough systematic approach to clinical history taking.

Ideal tool for the locum Optometrist


The OVU is a useful tool for researches, as it allows customizing several features in the design of its charts. It also incorporates charts that may have shown research value, even if they are not generally used (yet) in clinical settings (e.g.: Vanishing Optotypes).

Online access of the Unit also permits collecting uniform research data from different clinical settings for multi-centre analysis.
