Today I had a customer with the following prescription:
OD: Plano+4.00X90
OS: This eye had a very low acuity and wasn´t used by the customer.
Question 1? What spheric power (no toricity consideration was necessary)should I choose for the left eye in order to make that eye equal in size with the right eye.
Question 2? Is there any "thickness formula" for transforming toric lenses to spheric lenses considering only the optical center of the lens?Maybe the lens thickness is proportional to the spherical equalization?
I would be very grateful for any answer from you experienced people. I graduated recently and would be a humble listener to any suggestion.
