Final answer:
The far point for a -4.00 D prescription is 25.0 cm, representing the maximum distance at which objects are clear for a person with that degree of myopia. Monovision typically corrects the dominant eye for distance and the non-dominant eye for near vision. Based on the prescription, monovision with the left eye for near and the right eye for distance suits the patient's needs.
Step-by-step explanation:
The prescription described suggests that the patient has myopia, or nearsightedness, as indicated by the negative diopters for both eyes (OD: Right Eye; OS: Left Eye). For the eye with a prescription of -4.00 D (without specifying whether it's for glasses or contact lenses), the far point, or the maximum distance at which objects are in clear focus, can be determined by taking the reciprocal of the diopters (in meters). Therefore, the far point for a -4.00 D prescription would be 0.25 meters, or 25.0 cm.
When considering glasses that are 1.75 cm away from the eyes, the effective power of the lens system changes. This has to be taken into account when calculating the far point for glasses as compared to contact lenses. However, detailed calculations for this were not provided, and the question about the tear layer's power in the prescription indicates a need for optical knowledge to solve, making it advisable to seek professional optometric input.
For the part of the question concerning monovision, it's important to understand that monovision involves correcting one eye for distance vision (typically the dominant eye) and the other eye for near vision. According to the given prescription, Option (b) Monovision with OS (Left Eye) for near, and OD (Right Eye) for distance would be compatible given that the OD is less myopic than the OS, and the addition of +2.00 is present, suggesting reading or near work correction.
