Why does grandma not need glasses?



Jan 11 - 2015  |  Just about everyone has a story about an elderly relative that seemly has beat-the-odds and does not need glasses in later years.  How can this be possible considering what was talked about in my previous blog entry?  If the lens in the eye become stiff for everyone… then everyone should need eventually glasses… no?     Not exactly.   There are several common reasons when some folks can see well years after they should have needed reading glasses.  #1 – underlying refraction (nearsightedness, farsightedness, astigmatism)  In the right proportions and having different refractions between the right and left eyes (e.g. right eye is nearsighted while left eye has no significant refractive error) is the most common reason.  #2 – smaller pupils  With age, our pupils get naturally smaller and the depth of focus increases (like a pinhole camera) and this can give enhanced vision in good light.  #3 – surgery Advanced cataract surgery for cataracts can eliminate the need for glasses for both near and far vision.    dr.j  StudioEyeCare.com
