Read what our clients say about our products...

"We, and our customers, have been very pleased with the service that Cantor & Nissel Ltd provided during these challenging times. Short delivery times has been very surprising for both optometrists and their patients."

"I just picked up my custom hand painted lenses from #cantornissel and I have to say... They completely blow me away! I sent Teresa a concept design for the lens and her team have made the real lens look even more incredible! The depth is insane. Why buy cheap lenses when you can have a set tailor made to your eye profile, prescription and colour requirements? I'll certainly never be going back."

"To all budding CLO's and current CLO's, life does not always have to be a mindless tedium of dailies and monthlies, sometimes you can really make a difference. This 48 year old lady has a congenital defect and no vision in her left eye, she rarely looks at herself in the mirror. Today, I fitted her with a Nissel Custom Prosthetic and her husband has just emailed me to say that he cannot pull her away from the mirror."

"Some of you have sent me a message ask me about the contact lenses used in my last work. Well, you can buy from #cantornissel. They are so profesional with great talent. I don’t have any doubt that in my next work I’ll contact with them again."

"Teresa and her team for cosmetic lenses provide the most excellent service. She provides a bespoke and personal service, and is always willing to accommodate complex lenses and patients. Teresa is an absolute delight to liaise with and means that C&N are my top choice when fitting a patient with cosmetic lenses."

"The Cantor & Nissel team have always been a huge pleasure to work with and in the short time that we have known each other, I have developed a good working and supportive relationship with them. I really can’t recommend Cantor & Nissel enough; the team have always gone above and beyond to help me and the service/lenses that they have provided have always been of the highest quality."
