How Contact Lens Fitting Has Evolved With Digital Eye Measurement Technology
Contact lenses have long been a popular alternative to eyeglasses, offering clear vision and cosmetic freedom to millions around the world. However, the process of fitting contact lenses was not always as precise, efficient, or comfortable as it is today. Traditionally, optometrists relied heavily on manual measurements, trial lenses, and patient feedback to determine the right lens shape and fit. Thanks to rapid advancements in digital eye measurement technology, modern contact lens fitting has become more accurate, personalized, and safer than ever before.
