A client wearing corrective lenses has a visual acuity of 20/200. The nurse recognizes that the client:

The client whose vision is corrected to 20/200 is by definition legally blind because he is able to see at 20 feet what the healthy eye can see at 200 feet. Answer A refers to a refractive error, which is corrected by eyeglasses or one of the laser procedures. Answer C is an inability to focus on near objects due to a loss of elasticity of the lens and is corrected by the use of bifocal eye glasses. Answer D does not apply because the client would experience difficulty with vision at night or in dim lighting. Answers A, C, and D are incorrect because they do not explain what is meant by a visual acuity of 20/200.
