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.
Since 2005, the Verbal laboratory has become the unique manufacturer of Corning photochromic filtering lenses CPF®. They have proved invaluable for thousands of visually impaired people helping them to maximize their vision by reducing glare and increasing contrasts. They are the ideal solution for eyes that are hypersensitive to light or are affected by certain conditions that require a considerable improvement in contrast. This complete and unique range of mineral lenses offers two characteristics:
* the photochromism that enables quicker adaptation to variations in light conditions
* the filtering out of blue light as well as UV radiation.
Those lenses are indicated in pathologies such as age-related macular degeneration, albinism, cataracts, photophobia, retinitis pigmentosa, glaucoma…CPF® lenses are available in plano or prescription lenses including bifocal and progressive; Verbal also provides accessories such as CPF® trial kits and wraparounds to give maximum protection.
The design of our LUCEO® filters is based on our many years of experience manufacturing specialist tints that can really make a difference for patients. LUCEO® filters are made in plastic and this has great advantages in helping keep the spectacles light and comfortable. They also filter out the blue light but have no photochromic characteristics. To improve durability and visual comfort, each LUCEO® lens (except for the 450BD) is supplied with the following as standard:
* a scratch resistant coating to preserve the integrity of the lens
* an anti-reflection coating on the back surface of the lens to reduce ghost images
The plastic LUCEO® filters are particularly recommended to children, monophtalms or to people doing sport, who need appropriate equipments conforming to the current legislation. They are available in the following forms: trial sets, wraparounds, single vision lenses in plano and prescription, bifocal, progressive and degressive.
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.
