Final Answer:
Yes, a prism compensation device is used when checking lenses with prescribed prism.
Step-by-step explanation:
Prescribed prism in lenses is intended to correct specific eye alignment issues. When verifying these lenses, a prism compensation device is necessary to ensure the correct orientation and power of the prism. This device allows opticians or technicians to neutralize or compensate for the prescribed prism, ensuring accurate measurements and confirming that the lenses are made precisely as per the prescription.
The prism compensation device assists in aligning lenses correctly during verification, compensating for the prism effect and allowing for accurate assessment of other lens parameters like power and axis. It helps in verifying the accuracy of the prism and ensuring that the lens power and prism are in accordance with the prescription.
Using the prism compensation device is crucial in optometry and lens manufacturing processes, as it ensures that lenses with prescribed prism provide the intended correction for vision problems related to eye alignment, enabling accurate and effective vision correction for the wearer.
