Which chart is used to check near vision?

a. Jaeger
b. Trivex
c. Less chromatic aberration
d. Vertex compensation formula

The correct answer is: a. Jaeger

The Jaeger chart is used for checking near vision because it contains a series of varying font sizes, making it ideal for testing the clarity and sharpness of vision at close distances. B and C are incorrect because Trivex is a type of lens material and less chromatic aberration is a lens characteristic, neither of which are used for checking near vision. D is incorrect because the vertex compensation formula is used to calculate lens power for a specific distance, not for testing visual acuity at close distances.
