Our optimized design and exclusive Blu-Hu enhanced broadband coating ensures maximum image integrity.

Just one look and you'll recognize the quality advantage that our ezView BIO lenses deliver.

Why Choose an eZView Advanced Lens?
It's simple, really. These lenses are made of high index glass, which delivers wider ranges of view while retaining the magnification as compared to other lens designs. Coupled with our exclusive Blu-Hu AR Coating, they are the most advanced lenses available. Try them head-to-head and see for yourself.

All ion VISion lenses feature our exclusive Blu-Hu Enhanced Broadband AR Coating

This enhanced anti-reflective lens coating is specifically designed to minimize ambient reflection, delivering a pristine retinal image! This unique AR formula is optimized for use with all Argon, Diode and Yag laser systems.

Glass is better...

All imaging components in our contacting lens systems are made entirely from glass - even the contacting element - to ensure maximum image integrity. Say goodbye to the cracking, crazing and hazing that are typically associated with plastic optics.

These are the ONLY lenses on the market with this exclusive feature. No other manufacturer offers such a wide array of all-glass lenses. It's your money, why settle for less?

No fog. No mess. No kidding.

ion VISion gonioscopy and direct imaging lenses are composed entirely of instrument quality glass - there is no plastic to fog, haze or crack during everyday working conditions

Cleaning Instructions

1. As all ion VISion, Inc. lens components are completely glass, it is possible to clean the contact element's concave surface or coated imaging lens with alcohol, peroxide, or acetone. If these cleaning solutions are unavailable or further cleaning is desired, then proceed with these additional cleaning steps.

2. Immediately upon removal from patient's eye or use, thoroughly rinse the entire lens in cool or tepid water.

3. Place a few drops of mild cleaning solution, such as diluted liquid dish soap, or similar on a clean moistened 100% cotton cloth, ball, or swab depending on the cleaning area.

4. Gently clean the entire lens, insuring the contact concave surface and/or convex surfaces have been thoroughly cleaned to remove any debris, dirt, film, fingerprints or residue. Do not apply excessive pressure as this may cause scratching of the glass lens and/or coating.

5. Rinse entire lens thoroughly in cool or tepid water.

6. Dry the lens by using a clean 100% cotton cloth, ball, or swab or non-linting cotton tissue insuring to remove all water droplets from the imaging surfaces.

7. Proceed with disinfecting or sterilization instructions as required.

Disinfecting Instructions

1. Two methods of disinfection are recommended. To avoid lens damage, do not exceed recommended exposure time:

Glutaraldehyde: 2% or 3.4% aqueous solution. Temperature per manufacturer's instructions. Recommended exposure time 20-25 minutes.

Sodium hypochlorite / Bleach: 10% solution mixed at 1 part bleach to 9 parts water
Recommended exposure time 10-12 minutes.

2. Immerse the lens entirely in the chosen solution for the recommended exposure time. Either place lens on its side or insure all air bubbles are removed from under the lens for complete exposure.

3. Remove lens from the solution after recommended exposure time and rinse lens thoroughly with cool or tepid water to remove all disinfection solution with at least 3 rinse cycles of 1 minute duration.

4. Dry the lens by using a clean 100% cotton cloth, ball, or swab or non-linting cotton tissue insuring to remove all water droplets from the imaging surfaces.

5. Store in a dry storage case.

Ethylene Oxide Sterilization Instructions

Enhanced Broadband Coating

What is an Anti-Reflective (AR) coating?

The anti-reflective surface coating is one of the most important components of lens quality. Anti-reflective coating is an extremely thin, invisible multi-layer (5 or more) coating of metal oxide that is deposited on both surfaces of the lens. This multi-layer coating reduces the amount of light reflected from the lens surface allowing more light to reach the retina and thus improving image transmission.

Why do you need AR coatings?
Between 4-16% of light is reflected back or lost by a non-coated lens. By adding an AR coating, the overall transmission of the lens can be increased by up to 15%!

Why does the ion VISion AR coating have a "blue" hue?
As we move through the visible spectrum of violet, blue, green, yellow, orange and red, the wavelengths (400 - 700 nm) become longer. AR coatings work at different degrees across the color spectrum based on their design. Hence the anti-reflectance effect is not the same for all colors, which results in a slight color shift to the lens. This color shift can be controlled in order to maximize image transmission as well as offer a pleasing cosmetic hue.

Our exclusive Blu-Hu coating was designed to be effective in the visible wavelength range while optimized for the Argon, Diode and YAG laser treatment spectrum.

As a result, the blue/violet cosmetic lens tint named the ion VISion Blu-Hu Broadband AR Coating was created assuring nearly full transmission of the laser application.
