The device description focuses on the physical properties of tinted contact lenses and a haploscopic system, with no mention of AI or ML algorithms for image processing, data analysis, or personalized adjustments.
Yes
The device is indicated to "enhance color discrimination in patients with protan or deutan (red-green) color vision deficiencies," which addresses a medical condition, and can also be prescribed for "the correction of refractive ametropia." These are therapeutic uses.
No
The device is indicated for enhancing color discrimination and correcting refractive ametropia. Its primary function is to alter perception or correct vision, not to diagnose a medical condition.
No
The device description clearly states that the device is a soft contact lens with precision tinted pupils, which is a physical hardware component. The description details the materials and manufacturing process of the lens itself.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The ChromaGen v2.0 Haploscopic System & Color Discrimination Enhancement Soft Contact Lenses are a medical device worn on the eye. Their function is to enhance color discrimination and correct refractive errors. They do not analyze biological samples to provide diagnostic information.
- Intended Use: The intended use clearly states the purpose is to enhance color discrimination and correct vision, not to diagnose a condition.
Therefore, this device falls under the category of a medical device, specifically a contact lens, rather than an in vitro diagnostic.
N/A
Intended Use / Indications for Use
The ChromaGen v2.0 Haploscopic System & Color Discrimination Enhancement Soft Contact Lenses are indicated for daily wear to enhance color discrimination in patients with protan or deutan (red-green) color vision deficiencies. The lens may also be prescribed for the correction of refractive ametropia (myopia, hyperopia and astigmatism) in aphakic and not aphakic persons with non-diseased eyes. The lenses are disinfected using a hydrogen peroxide lens care system only and are available in a frequent replacement program.

Device Description
The ChromaGen v2.0 Color Discrimination Enhancement filters are designed specifically to improve discrimination between colors that are normally confused by people with protan or deutan (red-green) color vision deficiencies
The ChromaGen v20 Color Discrimination Enhancement Soft Contact Lenses are a range of soft contact lenses with precision tinted pupils of varying hue and saturation which, when used monocular and binocularly, have been shown to be of use in patients with defective color vision. Use of this product may enhance the discrimination of certain colors and may reduce the discrimination of certain colors. This device in not a cure for color vision deficiencies or colorblindness.
The ChromaGen v2.0 Color Discrimination Enhancement Soft Contact Lenses are tinted with FDA "listed" color additives. The color additives are used in amounts not to exceed the minimum reasonably required to accomplish the intended coloring effect. As part of the manufacturing process, the lens containing the color additives are thoroughly washed to remove unbound reactive color additives. The manufacturing process alters and/or changes the specifications to the clear version of a contact lens by affixing a listed reactive on that portion of the anterior (front) surface of the lens that corresponds to the iris. The ChromaGen v2.0 Color Discrimination Enhancement Soft Contact Lenses are tinted to the eyecare professional instructions.
The ChromaGen color additive effect is formed by reacting one or more of the reactive color additives listed in this paragraph with (poly hydroxyethy) methacrylate). The reactive color additives that may be used either alone or in combination are: reactive black 5, reactive blue 21, reactive blue 19, reactive blue 4, reactive blue 163, reactive red 11, reactive red 180, reactive yellow 15, reactive yellow 86, or reactive orange 78. The color additives used are not removed by lens handling or approved cleaning/disinfecting procedures. The ChromaGen v2.0 Haploscopic System & Color Discrimination Enhancement Soft Contact Lenses tinting process does not alter the optical and/or performance characteristics of the finished tinted soft contact lens.

PRECAUTION FOR CHROMAGEN LENSES
Special precaution for ChromaGen practitioners regarding the possible alterations in spatial perception.
Patients using the darker shades of tint in their ChromaGen lenses may experience some or all of the following:
- reduced low contrast acuity, -
- reduced illumination at night, -
- distortions in distance perception of moving objects or while driving, »
- distortions of apparent velocity. -
Thus, wearing these darker lenses may make driving difficult, especially at night, or under foggy, misty, or other adverse conditions.

Dear Mr. Dalsing:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
