The Newest Technology in Prescription Lenses

A number of advancements in prescription lens designs and materials make vision correction a more comfortable and rewarding experience.


Digital Lenses

The use of digital lenses in ophthalmic eyeglasses is increasing in eye care practices all over the world. Although this technology has been around for quite some time, it is becoming more common and preferred among lens laboratories. Many people are confused with the concept of digital lenses, often thinking that the lens itself is some kind of highly advanced equipment that one would see in a Sci-Fi movie. The truth is, digital lenses are just like ordinary lenses yet it the manufacturing process that sets them apart from traditional lens manufacturing. 

Digital lens processing offers a higher level of precision when creating the lens and also opens up the possibility to create extremely unique and versatile lenses in terms of shape and prescription. This is thanks to the equipment used to create the lens. By using processing equipment that requires the measure, analysis and computation of lens data in the form of numerical digits, both surfaces of a lens can be directly surfaced with a high level of accuracy. With this improved level of precision a patient will experience a more comfort in their prescription and a greater level of satisfaction. In the end, we can compare a regular lens to a tube television and a digital lens to a plasma flat panel television. Due to the manufacturing process, a digital lens allows for more peripheral vision and a sharper picture.

Instead of thinking of the term digital lens as an object think of it instead as a process; a digitally computed lens. There are many ways to digitally create a lens and this process is often referred to as the free-form process. Everything from the lens mold to the lens surfacing was creating using highly advanced software that digitally computed the data of the frame, the lens type, the prescription and the focal point. Yet it does not stop there, the lenses are then checked, buffed and polished using specialized equipment before they are ready to be dispensed.

In comparison, traditional lens processing does not use highly advanced equipment found in the free form process. Using lens molds with the prescription details already built in, the traditional process requires manual lens grinding and polishing. Although it seems that the quality of digitally processed lenses would be far superior this is not always the case. It is more so the quality of the production process of digitally produced lenses that exceeds the quality of the traditional lens process. Digital lenses allows for the customization of progressive lens designs that traditional processing cannot produce.
