A Snellen chart is an eye chart that can be used to measure visual acuity. Snellen charts are named after the Dutch ophthalmologist Herman Snellen who developed the chart in 1862. The use of this Snellen eye chart will help you determine the clarity of your distance vision. This can be useful to screen children for nearsightedness, which causes blurry distance vision.
