Did you know that your ability to see clearly from that fabulous pair of glasses you’re considering buying depends on lens quality and frame style? Find out why that is and how we can help you choose the best glasses, starting with the right exam.

There are more choices available than ever to help you achieve the look you’re craving with a new pair of eyeglasses. Frame color, shape, and size all play a role in your decision. But clear vision depends on lens quality and frame adaptability as well as measurements taken during your eye exam and frame selection process.

Dr. Sophia Barnes and her expert eye care team at Vision Corner in Houston, Texas, are committed to providing you the best of both worlds when it comes to glasses — frames that suit your style, personality, and prescription with high-quality lenses that provide the sharp, crisp vision you deserve.

Not all frames are created equal

Lightweight and durable frames that suit your facial contours and personal fashion sense are a must-have for glasses. But not all frames suit every prescription. Bifocals, stronger prescriptions, and certain lens types, for instance, are better served by frames that encircle the lens.

Choosing the wrong frame style can result in cracked or chipped lenses and/or zones of visual distortion (birefringence) that interfere with your ability to see clearly. At Vision Corner, we offer one-on-one expert assistance to help you choose frames that fit your style as well as your prescription.

What is birefringence?

Sometimes referred to as double refraction, birefringence develops when internal stress on eyeglass lenses cause areas of distortion in your visual field. With birefringence, you may notice that straight lines look slanted or objects in your peripheral (side) visual field appear blurry.

This is often the result of poor-quality lens material or poorly sized lenses being forced into an inappropriate frame. To overcome these challenges at Vision Corner, we offer only the best frames and highest-quality lenses available from superior brands such as Varilux® and Unity®, including transition, progressive, polarized, and digital surface lens types.

It’s important to note that some distortion is normal as your eyes adjust to a new frame style or lens prescription. If the distortion continues beyond a few days, you may be tempted to blame a faulty prescription.

Often, however, when we check glasses not purchased at Vision Corner, we find it’s birefringence and/or misalignment of the pupillary distance and optical center rather than an incorrect prescription that’s causing your visual symptoms.

Measuring for pupillary distance and optical center

To function properly, corrective lenses must be positioned within the frame so that the center of the lens aligns with the center of your eye. This, along with the right lens curvature, allows light to pass through your pupil and focus on the area of your retina that produces the clearest image.

Accurate pupillary distance (PD) and optical center measurements are required for proper lens alignment. At Vision Corner, we use specialized instruments to measure the pupillary distance of each eye (monocular PD) and your optical center. This results in a highly accurate alignment that online retailers and many in-store shops simply can’t provide.
