The specialist in visual impairment for therapeutic filters
The ophthalmic Verbal laboratory has gained a solid experience in the field of the correct filters for visual impairement, thus, it has become the unique specialist and interlocutor able to provide the most complete range of the market, concerning the equipments (single vision, bifocal, proximity, progressive lenses) as much as the materials ( mineral or organic). With its technical expertise, Verbal has build up today strong relationships in the world of the dedicated prescribers (ophtalmologists, hospitals…) and has entered into partnership with low vision organizations (Rétina France, l’AribA…)
Those lenses, particularly recommended for people with a visual impairement, filter out the blue light. Unlike ultraviolet radiation that can be filtered out by most aqueous and vitreous humours in the eye and by the majority of sunglasses, nothing stops the shortest wavelength of light from reaching the eye: the blue light. The INSERN U450 study, published in October 2002, demonstrated the threat of blue light to the retina. In addition to the photochemical lesions produced, blue light has the particularity of being scattered in every direction. This phenomenon causes glare and loss of contrast and the formation of ghost images. As soon as the cells become older, new pathologies can appear and lead to great discomfort.
The correct filters: CPF® and Lucéo®:
Since 2005, the Verbal laboratory has become the unique manufacturer of the photochromic filtering lenses CPF®. Those lenses are indicated in pathologies such as albinism, aniridia, aphakia, cataracts, age-related macular degeneration, glaucoma, photophobia or retinitis pigmentosa, their filtration is under a life guarantee. Not only is the blue light filtered out but also the CPF® lenses are photochromic.
The Lucéo® lenses also filter out the blue light but have no photochromic characteristics. The organic Lucéo® lenses are adapted to the children, to the monophtalms? or to people doing sport, who need appropriate equipements conforming to the current legislation.
The CPF® and Lucéo® Approved Opticians
In June 2006, the Verbal ophthalmic Laboratory has created an original concept for low vision: “The CPF® and Lucéo® Approved Opticians». The French opticians have profited by different helpful tools such as the trial kits and the prescriptions were promoted to the ophthalmologists, hospitals, eye therapists, associations… That is how the laboratory has federated a network of low vision specialists, mastering the therapeutic lenses. This device includes specific trainings, frequent conferences in France and enables to share the skills of the different professions. The goal is to better grasp the pathologies of the affected wearers and to make the right choice when adapting the filters. A methodology of adaptation is born from the collaboration with one of our consultant / lecturer, making the optician’s work easier.
