Visual acuity refers to the sharpness of vision, which is the ability to perceive details and distinguish between different shapes and colors. It is often tested using an eye chart that measures the smallest letters a person can read from a certain distance. A normal condition of the eye is not the same as visual acuity, as some people may have normal-looking eyes but still have poor vision. Double vision and reactivity to light are also not the same as visual acuity, as they refer to different aspects of vision.
