Contrast Sensitivity: Why Testing Contrast Sensitivity Is Critical For Optometrists

PRLog (Press Release) - Feb. 26, 2013 - For many years the Snellen and Log Mareye chart tests have been the foundation upon which most visual acuity assessments are based. They're quick, effective and accurate in determining eye conditions and the resolution of a patient's eye. But while the Snellen and Log Mar tests are highly effective in testing visual acuity, the fact still remains that visual function testing is just as important if not more.

The Chart 2020 Software System is a leader in visual function testing software which now features a live view remote app (built-in), now offers the most highly advanced contrast sensitivity testing software, taking advantage of the renowned FACT approach and providing unsurpassed digital acuity testing to help optometrists enhance and improve their practice and patient experiences.

An eye sight test such as the contrast sensitivity test assess the eye based on visuals one sees on an everyday basis. Visual acuity tests are performed with perfect contrast, 100% black on 100% white, while outside the testing room contrast levels are rarely ever this absolute.

This is what makes the contrast sensitivity test so key. For many people who are comfortable not wearing eyeglasses but experience vision problems while driving in the late afternoons and at night, the standard eye sight test will not be accurate. Individuals with these types of eye conditions can pass most LogMar or Snellen chart tests but when in real life situations they tend to struggle. This is why the digital contrast sensitivity testing that the Chart 2020 Software System offers is so important for optometrists to use.

The functional acuity contrast test (FACT) approach that the Chart 2020 Software System uses has been a leader in testing contrast sensitivity and vision function. This eye sight test helps optometrists predict eye conditions and visual acuity problems so that they can put together more comprehensive and insightful treatment plans. It also helps monitor vision over long periods of time and thus improves the relationships and trust an optometrist has with his/her patients.

In order to reap the greatest benefits from the contrast sensitivity test and other essential visual function testing tools, an optometrist needs to invest in the right visual acuity software.
