**Hydrolens Pastel Tint Custom Soft Medical Contact Lenses | Cantor Barnard**

Hydrolens Pastel Tint by Cantor Barnard is a custom-made medical soft contact lens that combines vision correction with customized tinting within the Hydrolens design, known for its wide range of available parameters and powers. The lens is designed for Daily Wear and can be used to correct Myopia or Hyperopia, with the option to add a Pastel Tint to enhance eye color, alter the appearance of the iris, or meet specific cosmetic and prosthetic requirements.

The lenses are delivered within a maximum period of 30 to 60 days from the date of order confirmation.

Hydrolens features a Spherical Blended Front Surface and Spherical Blended Back Surface design and offers an exceptionally wide range of custom parameters. The Base Curve ranges from 6.60 to 10.40 mm in 0.10 mm increments, while the Diameter ranges from 11.00 to 20.00 mm in 0.50 mm increments. Standard spherical power extends up to ±30.00D in 0.25D increments, with higher powers potentially available in selected cases.

For the Pastel Tint version specifically, Cantor Barnard’s current product information confirms that all Pastel Tints are manufactured using Contaflex 67% material. This material belongs to the Filcon 2 classification, with 67% water content and an oxygen permeability (Dk) of 37, according to official Hydrolens data. Therefore, Contaflex 67% is the appropriate material reference for the current Hydrolens Pastel Tint version on the product page.

Cantor Barnard offers two main types of Pastel Tints. Basic Pastel Tints generally work best with lighter eye colors and may allow some of the natural iris color to show through the tint. Opaque Pastel Tints provide greater iris coverage and reduce the visibility of the natural iris color. Clear/Open Pupil and Black/Closed Pupil options are also available, and tinting can be applied to the iris and pupil areas according to clinical or cosmetic requirements.

Currently published Pastel shades include Apple Green 1–3, Aqua 1–3, Blue 1–5, Violet 1–3, Brown 1–8, Grey 1–6, and Thames Brown 1–5. The shades vary in color intensity and the percentage of light transmitted through the lens. The manufacturer explains that a higher Light Transmittance percentage means that more light passes through the tinted lens.

Cantor Barnard states that Pastel Tints can be used for both Cosmetic and Prosthetic purposes. Certain configurations may be used to improve appearance, change or enhance iris color, or reduce glare, while the Black/Closed Pupil option may be used for vision occlusion purposes in cases determined by the eye care professional. Therefore, the tint type, iris zone size, and pupil configuration should be selected by a contact lens specialist according to the requirements of each individual case.

Hydrolens is a Daily Wear lens and is not intended for overnight wear. The manufacturer’s published maximum replacement period is up to 12 months, although the actual replacement schedule should be determined by the eye care professional based on the lens material, lens condition, ocular surface health, and the care system being used.

Cantor Barnard EV Aberration Control technology can also be added to the Hydrolens design when required. This is a single-vision optical enhancement designed to improve light focusing and support clearer, more stable vision, particularly under less-than-ideal lighting and contrast conditions.

Cantor Barnard lenses are manufactured in the United Kingdom. The company officially identifies itself as a UK Manufacturer and a specialist manufacturer of custom contact lenses based in Brackley, Northamptonshire, England.
