While the term "digital contacts" might refer to contact lenses incorporating advanced technology or digital manufacturing, the provided reference specifically describes digital lenses used for eyeglasses. These digital lenses utilize a sophisticated manufacturing process involving surfacing on both sides, distinguishing them from traditional lenses which are typically surfaced on one side. This process, often called free-form, allows the lens to be customized to a patient's prescription with very high precision, leading to potentially better vision performance than traditional designs where the best vision is centered.
Based on the reference, the key characteristic of digital lenses (for eyeglasses) is this advanced, precise, two-sided surfacing:
Digital vs. Traditional Eyeglass Lenses (According to Reference)
| Feature | Traditional Lenses | Digital Lenses (Free-Form) |
|---|---|---|
| Surfacing | Surfaced on 1 side | Surfaced on both sides |
| Customization | Best vision in the center | Customized precisely across the lens |
| Technology | Standard manufacturing | Advanced digital (free-form) manufacturing |
The reference highlights that digital lenses are surfaced on both sides and often called free-form because the lens is customized to the patient's prescription in a very precise manner, unlike traditional lenses which are surfaced on only one side and have the best vision centered.
The concept of using digital technology for precise customization is at the core of advanced optical products. While the provided reference focuses on how this applies to eyeglass lenses, the principle of precise, digitally controlled surfacing could theoretically be applied to enhance contact lens design as well, although the reference does not provide details specifically on "digital contacts." Therefore, based solely on the provided reference, a definition for "digital contacts" is not available; the reference describes "digital lenses" for eyeglasses.
