Normal visual acuity refers to the ability of an individual to see objects or images clearly without any blurriness. However, there are several other terms that can be used as synonyms for normal visual acuity. These include clear eyesight, sharp vision, excellent eyesight, 20/20 vision, normal eyesight, and razor-sharp vision. These terms indicate that an individual's eyesight is healthy and functioning normally without any issues such as nearsightedness, farsightedness, or astigmatism. Regular eye exams can help detect any changes in visual acuity and ensure that corrective measures are taken if necessary. A good eyesight is essential for performing daily activities with ease and comfort.
