Projectors are the best choice when it comes to obtaining accurate and precise measurements for reliable Visual Acuity (VA) testing.
They have become a common device used by Ophthalmologists. An Eye Chart Projector is the best alternative to standard panels and conventional light box-based eye charts.
Studies have proven that visual acuity testing using a projector gives reliable measurements compared to standard panel-based eye charts. The availability of multiple charts lets them standout amongst rivals. It comes with numerous charts to conduct various tests, including the Phobia test, Minute Stereo Test, Coincidence Test, Dot Test, Fixation Spot Test, Astigmatic Dial Test, Cross Cylinder Test, Binocular Balance Refractive Test, Schober, and the Snellen letters with red/green filter, etc.
