Zacks are fantastic and the optician that took my appointment was incredibly professional. I have spent years with very uncomfortable prescriptions, and they took the time to really dig into what was going on. A complete eye health check with some really fancy 3d scanning showed all was ok there, so the problems I was having came down to my previous prescriptions and how out of balance they had been. Putting on the new prescriptions for the 1st time was fantastic, no more eye strain. A relief! Thank you Zacks, patient for life. If you need a full clinical eye exam, this is the place.
