A Snellen chart is a tool used by eye care professionals to measure visual acuity. It consists of rows of letters that decrease in size, with the largest letter at the top. Patients are asked to read the letters from a certain distance, typically 20 feet, to determine the sharpness of their vision.
While Snellen charts are commonly used in eye exams conducted by optometrists and ophthalmologists, they can also be used at home for self-monitoring of vision. Printable Snellen charts are available online for free, making it convenient for individuals to check their vision in the comfort of their own homes.
