How Should I Choose Frames?

At San Gabriel Eye Center, our optometrists in Georgetown will help you choose the best frames for your unique face. We'll guide you toward frames that rest with equal weight on your nose and ears, lightly gripping your temples. The perfect frames will be equal to the width of your face. While the decision is ultimately up to you, our optometrists in Georgetown will provide expert assistance and guidance. 

Can I Use My Eyeglass Prescription For Contact Lenses?

We recommend you have a separate prescription for contact lenses and your glasses. Each prescription requires certain measurements to ensure a proper fit.

What Does the Minus (-) Mean on My Prescription?

All refractive errors are measured in diopters, which are optical units that describe the strength of a lens. Myopia or nearsightedness is measured with the minus (-) sign and in increments of .25. This problem is when you have difficulty seeing objects far away. Myopia is categorized as:

  • Mild nearsightedness: -.25 to -3.00 D
  • Moderate nearsightedness: -3.25 to -5.00 D or -6.00 D
  • High nearsightedness: Greater than -5.00 D or -6.00 D

What Does the Plus (+) Mean on My Prescription?

Farsightedness or hyperopia is when you have difficulty seeing objects up close. Hyperopia prescriptions are measured in positive (+) increments and will be classified as:

  •  Low or mild hyperopia: +2.00 D or below
  • Moderate hyperopia: +2.25 D up to +5.00 D
  • High hyperopia: Over +5.00 D

What Is Pupillary Distance?

Pupillary distance (PD) is the amount of space between the center of your left pupil and the center of your right pupil. Your pupil is the black circle that expands and contracts based on the amount of light available. PD is an essential measurement our optometrists in Georgetown will take to precisely center lenses in frames.

How Can I Have My Frames Adjusted?

If you need your frames adjusted, the experts at San Gabriel Eye Center can help.

How Often Should I Get New Glasses?

This answer depends on a range of individual factors, such as your lifestyle, changing needs, and tastes. In either case, the general optometry rule is to have an annual vision exam to see if your vision needs have changed. However, if you notice problems with your vision, you should reach out to us immediately for an evaluation.
