Final answer:
The question pertains to calculating the near point for glasses 2.20 cm from the eyes for a child with a 0.750 D prescription in Physics, but without additional details, an exact answer cannot be provided. Typically, the lensmaker's equation would be used in such problems.
Step-by-step explanation:
The student's question appears to relate to the subject of optics within Physics, more specifically to the context of corrective lenses for vision. The prescription given has a power of 0.750 diopters (D) for a child's eyeglasses, and the student is asking to calculate the near point for glasses that are 2.20 cm from the eyes. To find this, we need to understand how the corrective lens changes the focal point of the eye to correct the near point of vision.
However, without a complete problem statement including the child's current near point without glasses or the power of the glasses, we cannot provide an exact answer. Typically, such a problem would utilize the lensmaker's equation, which is 1/f = 1/do + 1/di where f is the focal length, do is the object distance, and di is the image distance. The near point would then be calculated by considering the combined effect of the eyeglass lens and the eye's lens system.
