Digital Lenses is an over-used term, confusing term. Lets "clear" it up. These days, the word digital is used in just about everything related to technology, an over used marketing gimmick. If you go back in time everything was analog. Then computers and semiconductors came along and starting transforming things that were previously analog into digital. That doesn't mean digital is better, but it can be. As we fast forward in time, digital has the ability to be better, but it requires extensive software development in order to make it better. And not all software is good software. This is where the proof is in the pudding. But we digress.
Some lenses are part digital and part analog. Some lenses employ digital technology that is inferior due to poor R&D, testing, or simply didn't apply enough financial resources to make it good. In these cases, an old style analog lenses can sometimes outperform a digital lens. Suffice it to say, some lenses that are claimed to be digital are not, and some that are, well, just not very good.
In a true, digital lens, expensive robots are employed to create the lenses. This is another source of confusion. Just because a robot is creating the lenses, doesn't mean it is customized to you and your prescription. The robot may be making a one size fits all lens, mass producing them for anyone. This is not a customized digital lens. A true customized, digital lenses would start with you, the patient, in our office, taking precise measurements which ultimately get fed to that robot, and the robot will create a specific lens, for you. Are all robots good? No, some are not very precise. Their accuracy can vary, and this is directly related to how much the robot costs. Another factor in robotics is calibration. Does the company take time to calibrate the robot on a regular basis? This costs money. All of these factors will decide on how good your lenses are, and how much they cost.
