Understanding Essilor progressive lens markings involves knowing that these markings assist in identifying the type and orientation of the lens. Essilor, a renowned eyewear manufacturer, places tiny marks on their progressive lenses. Generally, found on the bottom of the lenses, these nearly invisible marks consist of engraved letters and numbers that represent the lens type and brand. Additionally, there may be circles or an ‘E’ mark that indicates the reading portion of the lens, ensuring correct orientation during placement. Hence, these markings act as a guide for both eyewear users and opticians to correctly position the lens and provide optimal vision correction.
What Are the Progressive Markings on Glasses Lenses?
Progressive markings on glasses lenses are symbols and identifiers that help optometrists and wearers understand the properties and features of a particular eyeglass lens. These markings are crucial in the manufacturing process, ensuring that the right lenses are created for different types of prescriptions and visual needs.
These symbols usually appear as two small circles that are placed at the 180° line. Other symbols or markings may include different shapes, dots, and even numbers, all of which have a specific meaning and function related to lens properties.
These may include symbols used to indicate lens materials, such as high-index, polycarbonate, or trivex, which affect the lenss thickness, weight, and durability. Other markings may indicate filters or tints, which can enhance visual acuity, reduce glare, or offer UV protection.
Another important progressive marking on glasses lenses is the recommended minimum height or corridor length. This is especially important for people with higher prescriptions or special visual needs, as it determines the size of the reading and intermediate areas of the lens. By following the recommended minimum height or corridor length, optometrists and lens manufacturers can ensure that the appropriate lens design is selected for each individual.
They allow optometrists, lens manufacturers, and wearers to select the right lenses based on specific prescription needs and visual requirements. By understanding these markings, wearers can make informed decisions about their eyewear and ensure optimal visual performance.

Do All Progressive Lenses Have Markings?
But thats not to say that all progressive lenses are completely devoid of any markings. In fact, some manufacturers do include subtle markings on their progressive lenses to help wearers adjust to the different zones of vision. These markings usually consist of tiny letters or numbers etched into the lens, indicating the location of the intermediate and near zones. However, these markings are often so small and inconspicuous that they’re difficult to detect without close inspection.

Progressive lenses, on the other hand, require a bit of trial and error to find the right spot for each distance. Markings can provide a valuable guide for wearers who’re still getting used to their new lenses.
Some people are able to adapt to the lenses quickly and easily without any additional guidance. Others may prefer markings for an extra bit of help, but don’t find them necessary. Ultimately, it’s up to the individual wearer and their specific needs and preferences.
