What is considered normal eye vision and how can it be measured or assessed?
Normal eye vision is typically defined as 20/20 vision, which means a person can see at 20 feet what a person with normal vision can see at 20 feet. This can be measured through a visual acuity test, where a person reads letters on a chart from a specific distance. Other assessments may include a refraction test to determine the need for corrective lenses, and a visual field test to check peripheral vision. Regular eye exams are important to monitor and maintain good eye health.

4.75 vision refers to a specific level of visual acuity measured in diopters, indicating that the individual is nearsighted (myopic) and requires corrective lenses for clear distance vision. The number can be understood as a prescription strength for glasses or contact lenses, where a higher negative number signifies a stronger correction needed for clarity at a distance. In practical terms, someone with 4.75 vision may struggle to see objects clearly beyond a certain distance without corrective eyewear.
