Online Eyeglasses Shoppings




For some people, buying eyeglasses online may be an OK way to get a new pair or two. But for others this may end up to be a complete disaster. A lot of different considerations go into selection and function of your eyeglasses to include;

• Pupilular distance (PD measurement)

• Bifocal or Ocular Center measurements

• How high is the sphere power

• How high is the cylinder power

• Is there ground in prism

• Different materials available and can the person adapt.

• Base curve requirement

• Types of lenses available

• Other options that assist the lenses in optimum performance

• Type of frame… metal or plastic.

• Eye conditions being treated with the prescription eyeglasses.
