Which test uses tools like a Snellen chart to screen for visual impairments?

The test that uses tools like a Snellen chart to screen for visual impairments is visual acuity testing. The Snellen chart is specifically designed to measure the sharpness or clarity of vision at a distance. It consists of rows of letters that decrease in size, allowing healthcare professionals to assess how well a patient can see at a standard distance, typically 20 feet.

Visual acuity testing is vital for identifying various vision issues, such as nearsightedness, farsightedness, or more complex eye disorders. This assessment helps determine whether a patient needs corrective lenses or further evaluation by an eye care specialist.

The other options do not pertain to visual screening. Objective information analysis generally refers to evaluating data or information rather than conducting tests to measure eyesight. Audiometry is specifically focused on hearing and involves different tools and methodologies to assess auditory function. Fatigue assessment evaluates a person's level of tiredness or energy rather than their visual capabilities. Thus, visual acuity testing is the correct choice as it directly relates to the process of examining vision using tools like the Snellen chart.
