We offer infinite solutions to all of your optical needs by employing cutting-edge technology to create the latest digital lens designs and 3D-printed lenses. As a matter of fact, our business is built on providing you with digitally produced, high-definition lenses that you may not be able to find anywhere else.

While you may have chosen a traditionally surfaced lens in the past for your glasses, lately you might have noticed a lack of clarity or uncomfortableness with them. If so, it might be time to upgrade to a digitally surfaced lens. You’ll soon discover what you’ve been missing out on the whole time: clearer vision everywhere you turn, no matter the lighting situation.

To understand what makes a digitally surfaced lens far superior, let’s take a closer look at the difference between traditionally surfaced lenses and digitally surfaced lenses.

Traditionally Surfaced Lenses

Traditionally surfaced lenses are created with a hands-on approach that is very laborious and time-consuming. Lab technicians are in charge of making sure the materials they select for your lenses match your prescription. The lenses have to be laid out, marked, and blocked all before they can be processed. Once the surfaces have been generated, the lab tech must choose from among hundreds of pre-made tools before they are fined and polished. If all goes right, these tools get the Rx within 1/10 of a diopter of the actual prescription.  Then the lenses have a scratch-resistant hard coating added to the back surface that is UV cured.

Digitally Surfaced Lenses

In contrast, digitally surfaced lenses are high-definition lenses that are created with state-of-the-art equipment, using a diamond-point lathe cutter controlled by computer software. The prescription is carved into the back of the lens blank. Your lenses can be created specifically for your vision needs and the lab doesn’t have to use a pre-made lens to start with, nor are premade tools used to polish the lenses so they are polished within 1/100th of a diopter of your actual prescription, 10 times more accurate than conventional lenses.

In addition, digitally surfaced lenses can be created for just about anyone who wears glasses, no matter if they need single vision or progressive lenses. The lenses can be created from thin and light materials, which means more comfort for all-day wear. They can also receive non-glare treatments, tints, and they can adjust to changes in lighting conditions with photochromic technology. These lenses will be sharper and will provide a larger field of view than traditionally surfaced lenses.

At R&D Optical, we offer our Visual Perfection HD Digital Lenses, a unique and customizable group of lens designs. You will receive a unique lens calculated just for you with state-of-the-art, innovative technology that improves your lens performance for any gaze direction.
