Costs of going to the eye doctor or optometry office may hinder you if paying out of pocket for eye glasses. Buying prescription eyeglasses online might be a sensible alternative, addressing any visual impairment while staying within the confines of a restrictive budget. Some key points to consider when placing internet orders includes the following:
Choosing your glasses
The best glasses are those that flatter the wearer and that are more likely to be worn consistently, which is advantageous to prevent further deterioration of vision. It is estimated that over 150 million people struggle with a refractive error, which is basically a blurriness in their near or distance vision.
Online merchants will offer suggestions for frames most suited for men, women, or youth wearing their glasses, based on typical face shape and size. It is helpful to have available a clear and current facial photo, as some sites offer a “try-on” option, that allows potential buyers the opportunity to visualize different frames by superimposing them over an uploaded image. Customer service or support contacts will assist buyers further when ordering online as needed, and to ensure satisfaction.
Measure Pupillary Distance
Be sure to take precise measurements directly from current eye prescriptions to provide to online vendors of eyeglasses and this includes an accurate pupillary distance (PD). PD is often measured by lab technicians that create the glasses that you order. To measure, use the millimeter side of a straight ruler and measure the distance from the bridge of the nose to the inside center of each pupil. An average or default measurement for PD often used is 63. This number is particularly relevant for those with stronger eye wear prescriptions, as it relates to the optical center of the eye and can greatly impact visual clarity if not precise.
Difference in Cost
Many may wonder how online retailers can sell prescription glasses for a fraction of what is found at local optometry venues. The difference lies in the lenses crafted for the pair of glasses. While an eye laboratory may form each lens based on the patient’s specific impairment and measurements, those merchants who offer low-cost glasses may be cutting standardized lenses to fit the prescription. The major difference may be found in visual clarity of items outside the central line of vision, which accounts for the price differential.
Buying eyeglasses online is a great way to keep up with the rising cost of eye health, and to secure a second pair to keep on hand. This is also a practical option for those ordering for children, who may need subtle vision augment but that possess higher potential for loss or damage of glasses due to age and lifestyle.
