If you’re considering purchasing varifocal glasses online, it’s essential to understand the potential challenges and risks involved. While it may seem convenient, especially in today’s digital age, there are important aspects that online retailers often overlook. Here, we discuss the critical factors you need to consider when buying varifocals and why it’s crucial to choose a reputable service like ‘Glasses at Home.’
Ocular Centre Height and Dual Pupillary Distance
The key to ordering varifocals online is accurately communicating two vital details: your ocular centre height and your dual pupillary distance. These measurements are critical for ensuring that your lenses are correctly aligned to your eyes. Varifocal lenses are intricate and require precise positioning, taking into account your unique facial structure and how the frame fits you.
Measuring Your Ocular Height (OC)
Your ocular height (OC or OCH) determines the vertical distance between your pupils and the lower part of your lenses.
A trained optical consultant plays a pivotal role in the varifocal glasses fitting process. They ensure the frame fits securely to prevent slippage during head movements, make certain the customer maintains a natural posture, and take precise vertical measurements from the center of the pupil to the bottom of the frame. These steps are critical and underscore the importance of in-person professional assistance when ordering varifocals to avoid issues that may arise from incorrect measurements.
Measuring Your Dual Pupillary Distances
Dual pupillary distances refer to the horizontal position of your pupils behind the lenses. It’s essential to measure both PDs for both eyes, as this measurement is often missing from prescription papers. A trained optical consultant will ensure you get accurate measurements.
Choosing the Right Varifocal Lenses
Varifocal lenses have three main vision “zones”: close, intermediate, and distance. Your choice of lenses depends on your specific needs. Everyday varifocals cover all three zones and are suitable for reading, watching TV, and driving. Occupational varifocals, on the other hand, are ideal for tasks that require you to see at shorter distances, such as working on a computer.
It’s crucial to have an up-to-date prescription when ordering varifocal glasses. As a varifocal wearer, your eyes may change more frequently, so getting an eye examination at least every 2 years is advisable. An accurate prescription ensures that your new glasses meet your vision needs.
