Answer :
Final answer:
The correct prescription to provide over the existing contact lenses for near tasks is option d) OD: -3.50, OS: -2.00, Add +2.00, given that the contact lenses already correct for distance and the Add power of +2.00 is for near work.
Explanation:
The prescription that should be prescribed over contact lenses (CLs) for near tasks is as follows:
- OD: -3.50 DS
- OS: -2.00 DS
- Add: +2.00
Since the patient is already wearing contact lenses that correct their vision, they only need the additional power for near work, which is the Add power of +2.00. The contact lens prescription is taken into account for distance correction, and the Add power is for near tasks.
The correct answer from the options provided is:
- d) OD: -3.50, OS: -2.00, Add +2.00
The patient's contact lens prescription in Air Optix Aqua is OD -3.50 DS and OS -2.00 DS for correcting distance vision. For near tasks, we add the Add power of +2.00 to the existing contact lens power.
