Your Top Vision Questions Answered by Seattle’s Cannon EyeCare
Have unresolved questions about eye health? Your optometrist is your best resource. At your next Cannon EyeCare visit in Seattle, consider asking:
1. How Is My Eyeglass/Contact Prescription Determined?
Seattle specialists use three precise methods:
