To realize glasses that guarantee a perfect vision, it is not enough to do an accurate vision exam or the choice of a frame and two good lenses; it is also necessary a precise realization in the optic laboratory. At the Santona Optic Centre you can count on an optic laboratory characterized by efficiency and professionalism. In our laboratory, professionalism of the team and quality of instruments permit the best care in glasses realization. A precise centering of lenses, their cut, the suitable insertion in the frame chosen by the client, permit to obtain personalized glasses, perfectly fitting on the client face as a tailored suit.
Frames and ophtalmic lenses
Glasses are a personal object, composed by a frame and two ophthalmic lenses. It is useful but also fashion. Thanks to the different colors of frame and various shapes of ophthalmic lenses, you can adapt it to your own personality. Sober or hi-tech frames, easy colors or long shot motifs, classical forms or made to be embellished by sophisticated details: many frames are at your disposal at the Santona Optic Centre to be worn, valuated, and compared. To discover every brand you can find at the Santona Optic Centre, you should visit the website at the voice Eye Glasses in the section Products. Professionals of our Centre have a qualified experience in offering advices, looking for a complete satisfaction of your tastes and offering, at the same time, the best solution (frame and ophthalmic lenses) for your vision issue. The main purpose of glasses is always their functionality in vision correction. Choice of the frame (shape and size) and ophthalmic lenses (materials, geometry and treatments) are crucial. The frame must satisfy an aesthetic taste but also perfectly fit on your face. That is why is so important relate it to:
- shape and size of the face
- eyes position in the face
- distance between pupils (which divides the eyes)
- size and shape of the noise
- Kind and entity of the vision problem to correct.
Ophthalmic lenses can be selected in a wide range of products. You will be advised considering:
- Typology and entity of your vision problem
- Your necessity according to the way of use of the vision correction
While you are choosing glasses, someone of our team will empathize with you and inform you (at the end of the vision exam) about your condition, advising you in appropriate way. Lately, the optic laboratory realizes what has been said at the Optic Centre during the vision exam and the choice of frame and lenses. So the Optic Laboratory is highly professional and equipped with advanced tools and technologies, and is led by industry professionals.
A correct realization of glasses demands an accurate vision exam, a clever choice of frame and lenses and a precise centralizing according to the specific characteristics of your face and eyes. Parameters to consider for a good centralizing are:
- Distance between vision axis
- High of vision axis
- Distance between corneal apex and lens
- Pantoscopic angle
- Frontal angle
- Distance for a correct use of glasses
During the centralizing, precision reduces vision diseases given by the use of lenses. Those diseases, which get worse when the subject does not look in primary direction, are especially perceived during the phase of adaptation to the new glasses.
A correct centralizing of lenses is important to avoid abnormal postures (of eyes, head and body), to reduce vision diseases and to reach the best vision acuity.
A correct centralizing of lenses is even more important when we do glasses with progressive lenses or lenses with depth of field (characterized by a more complex geometry then monofocal lenses) or glasses with prismatic correction.
At the Santona Optic Centre, the collection of such parameters happens in detailed and deepened way, including different ways of measure in order to compare results and be able to trace back, with major precision, to the true measure. We proceed by hand using specific tools as the pupil distance meter, graph rulers and goniometers; manual measures get completed using sophisticated digital tools, as the video centralizer.
The pupil distance meter can do accurate and precise digital shots, producing high-resolution images; those images can be elaborated with a software, in order to have all necessary parameters for a correct centralizing of lenses and their personalization according to the person’s characteristics.
Edging and grinding
Edging phase is very important in the realization process and consists in giving the shape to the lens; at the Santona Optic Centre we use traditional digital plotters or the remote edging system. Traditional digital plotters are connected to the automatic grinder of the laboratory, which provides cutting the lens with the exact shape of the frame. The remote edging system, at the contrary, uses a specific digital plotter which reveals the shape of the frame and sends it directly to the external laboratory; in this case ophthalmic lenses arrive at the Santona Optic Centre already cut and so ready to be inserted in the frame. This is the moment to refine and insert lenses in the frame, by following different procedures according to the typology of the lens (monofocal, progressive, with depth of field) and of the frame (cellulose acetate, metal, glasant, nylor).
