Did a very thorough examine and carfully considered how and what I use my eyes for , e.g. for reading, computer work. Made subtle adjustments to my prescription to optimize and upgrade my current prescription which was more for reading at 14 versus prolonged computer work at 18. Included was a medical examine for various medical problems that cane occur, cataracts, Glaucoma, etc. Was not intimidated by my technical questions and provided me with a better understanding of the focusing condition and stigmatic corrections needed in each eye.
