Detailed Solution
Download Solution PDFVisual acuity refers to the sharpness or clarity of vision and is an essential aspect of eye health.
Key Points
- The Snellen chart is used to measure visual acuity. It consists of rows of letters that decrease in size as one moves down the chart.
- The individual reads the letters from a standardized distance, typically 20 feet, to determine their vision clarity. The results are expressed as a fraction (e.g., 20/20 vision means normal vision, while 20/40 means the person sees at 20 feet what a normal eye sees at 40 feet).
Thus, it is concluded that Visual acuity can be measured by the Snellen chart.
Hint
- A Hoover cane is a mobility aid for visually impaired individuals.
- A prosthetic device replaces missing body parts, such as artificial limbs.
- An orthotic device supports or corrects physical impairments, mainly related to movement, not vision measurement.
