| Popis: | We describe a set of distance and near, adult and child, visual acuity tests for home use. The five charts are packaged in a PDF document and are also available as JPEG images that can be printed on standard letter paper or displayed on a monitor or handheld device. Adult distance visual acuity is tested using a modified ETDRS Chart R; child distance vision is tested using a similarly formatted HOTV logMAR chart. Testing distance is 5 or 10 feet, appropriate for home use. Near visual acuity is displayed in the range of J16 to J1 using random words (for adults) or in HOTV matching format (for young children). An Amsler Grid and HOTV matching card are included. The charts include a calibration circle. For those without a printer, sending a JPEG image as an email attachment initiates onscreen testing with a single click. Devices with smaller screens require an assistant to scroll through the display. The test can performed without assistance from a printed page. |
