MODALITY: 12 months maximum. Replacement frequency is at the discretion of the Eye Care Professional.
These lenses may be made with occlusive black pupils or clear pupils with virtually any prescription, including toric. Lenses may be stabilized to allow the iris to be offset on the lens. The scleral portion may be hand-painted and veined and used to cover a strabismic eye.
When fitting patients with offset pupils/strabismus in a Nissel Custom lens we offer the Stabilized Fitting Lens to determine the best fit and best overall shape and thickness of the lens as well as the position of the pupil on the custom lens. The goal always is to perfectly match the customized lens to the patient’s good eye.
The color match is very important for overall appearance and patient satisfaction.

Nissel Custom Photo/Image Guide FAQ
Our lenses will only be as accurate as the images we receive!
Cantor Barnard have combined the repeatability of printed lenses with the artistic flare of hand painted lenses. This has resulted in the Nissel Custom lens.
WHAT DO CANTOR BARNARD REQUIRE? Obviously, we cannot match a lens without a photographic image. However, the quality of the image will determine the overall quality of our finished lens.
I HAVE A SAMPLE – LENS CAN I USE THAT? If your patient has had a lens previously, we can use that to help making a new lens. The lens would need to be sent to our offices along with your order.
HOW FAR AWAY SHOULD THE PHOTOGRAPH BE TAKEN? Ideally the image should be taken between 6 & 12 inches away. A close image is not always best, please make sure the image is in focus.
DO YOU REQUIRE BOTH EYES IN THE PHOTOGRAPH? Yes. we will require both eyes so that a good match can be made, taking both eyes into consideration.
WHY DO YOU NEED A PIECE OF WHITE PAPER HELD AGAINST THE FOREHEAD? Our artists will require a base point to start from, using a piece of white paper will enable them to adjust the image to get a better colour match.
WHAT KIND OF LIGHTING DO YOU NEED THE PICTURE TO BE TAKEN IN? The picture is best taken with as much natural light as possible making sure not to have the light source behind the subject.
WHAT DO YOU DO IF THE COLOUR OF THE LENS YOU RECEIVED IS WRONG? Although we make every effort to make sure the lens is correct first time, there are factors which may make the lens look different from the good eye. By sending us a new photograph with the lens on eye and the good eye in the same image, we can make any adjustments to correct the colour.
All images in this guide were taken using a well-known brand of smart phone, with an 8-megapixel camera. You do not need to spend hundreds of pounds on a camera to get quality images that we can use to reproduce the natural eye.
We prefer that images be sent with an email in Jpeg format rather than printed and sent by post. Images that cannot be used to reproduce a lens will be returned for improvement.
