Thank you for your responses.

Muscle weakness can cause misalignment of the eyes and double vision. It appears your double vision is due to a weakness of the 4th cranial nerve causing weakness to one of the left eye muscles.

The optician was likely suggesting prisms in your spectacles which can bring the two images together. This can be very helpful in resolving the double vision. Your doctor will have to measure your eyes for new glasses and determine how much prism to place inside. Surgery to the eye muscles may be another option if the double vision is not changing.

The double vision is not permanent, I can pull the two images together especially in the mornings. What will the effect be of the prisms on this ability?

you can bring the images together if you focus and coordinate the two eyes. That takes work and can fatigue your eye muscles. The prisms will allow you to see one image without having to work your eye muscles. So it will prevent eye strain and maintain single vision throughout the day.
