Refractive Errors/Eye Glasses/Contact Lenses

What is a refractive error? Refractive error means the shape of your eyes does not bend light correctly resulting in blurred vision. The 4 main types of refractive errors are myopia (nearsightednes), hyperopia (farsightednes), presbyopia (the loss of the ability to see near) and astigmatism.


  1. Blurred vision.
  2. Difficulty reading, seeing up close or in the distance.

Myopia or nearsightedness:
Very commonly inherited and usually discovered in the teenage years. Close objects are clear and distant objects are blurry.

Hyperopia (farsightedness):
Close objects are more blurry than distant objects.

Usually occurs from unequal curvature of the cornea. In other words, the meridians of the cornea have different curvatures. This causes objects to appear to be doubled. This astigmatism is often present in combination with myopia and hyperopia.  

Natural aging of the lens of the eye.
After the age of 40, the lens of the eye becomes more rigid and does not move as easily. This is the reason why people with excellent distant vision often need reading glasses in their mid 40s.

Refractive error can be corrected with either glasses or contact lenses or LASIK. Dr. Zimm specializes in the surgical correction of myopia, hyperopia, stigmatism and presbyopia through the use of an advanced VISX laser system. All Saints Eye Center has the most advanced VISX laser system.

“As an avid fisherman, golfer and building contractor I rely on my eyes a lot. Dr. Zimm helped correct my long distance vision to the point that I no longer have to strain my eyes to see the fish or watch the golf ball. They also fitted me for the right glasses to wear driving vs. out on the boat and golf course. Major improvement in quality of living!!!”


“I went for my eye exam at All Saint's and could not have been more pleased. Pia was friendly,professional, and patient with me. I did not feel rushed like I did at my last eye dr. Dr. Donaghy wasequally relaxed and through. Highly recommend!”

Catie Hart

“Just had LASIK here. The first appointment took a while, but that's because they did a lot of testing. Theyhad me scheduled the next week and they did the surgery within about 1 hour. Dr. Zimm was very nice,chill, and laid-back, which put me at eas. I couldn't get one of my eyes to cooperate, but he stuck with itand helped coach me through not moving it during the surgery.”
