A condition in which there is reduction of visual sharpness or of peripheral visual field, which cannot be corrected by conventional means. By definition, the individual affected by lowvision has available a corrected sight lower than 3/10 and/or an alterated visual field. In younger surbjects, visual reduction is present since the birth, whereas whenever adults are affected, this is most frequently due to pathologies such as senile macular degeneration, diabetic retinopathy,high myopy, cataract, pigmentous retinite, glaucoma, cheratocone, and traumas.
Electronic magnifyer with optic zoom with adjustable enlargement from 3X to 40X
TREATMENT OF lowvision
the optometric and ophtamologic component of visual rehabilitation. It includes
optometric visual analysis, prescription of spectacles, lenses, and supermagnifying
optic systems.; it comprises also education to use auxiliary devices and
residual sight, and, lastly; whenever necessary, the patient is directed
to other rehabilitation services.
In our Center are available various magnifying devices, and we can safely confirm that even patients with visual residual rated 1/10 can return to read.
Our Center deals since 20 years with patients afflicted by reduced vision; thanks to most updated knowledges, we are in condition to provide even to half-blind patients the possibility to read.
After an accurate optometric examination, they have the opportunity to test immediately special lenses or most suitable magnifying devices.
VISUAL AND ELECTRONIC SUBSIDIARY DEVICES FOR SUBJECTS AFFECTED BY LOWVISION
The microscopic prismatic glasses are practical and powerful visual aids. They can be prescribed even with very high enlargement ( from 2 to 12x)
Binocular, widescoop galileian system, suitable for near or distant focusing.Enlargements from 2x to 5x.
OCUTECH VES AUTOFOCUS
The Ocutech Ves autofocus system allows the patient to move normally even outdoors; the system is based on a keplerian optics principle, with automatic focus adjustment from 30 cm to infinite; enlargements from 3x to 6x.
THE CLASSROOM SYSTEM
The classroom method allows to view the texts written on the blackboard and at the same time to watch the the desk. The camera that uses the Easy School system is autofocusing, thus allowing to watch a person who talks and moves with no problems of manual focusing. Enlargement is adjustable from 3x to 40x.
Practical and effective are the supermagnifying lenses that allow to enlarge hugely scripts and images.
FIELD MAGNIFYNG LENSES.
Nowadays, patients afflicted by loss of visual field due to cardiovascular or traumatic events, can improve their peripheral field with the new EMIANOPTIC lenses by Dr. G.K. Sterns, MD from Rochester, N.Y.
The loss of peripheral visual field is caused by pathologies such as glaucoma or pigmentous retinite. The consequent tunnel-shaped vision can be widened with the special prismatic lenses.
lowvision AND PHOTOPROTECTION
caused by excessive exposure of skin to sunlight are often mentioned not
as much are the damages to sight.
The recent studies of Dr.JJ Weiter and Dr.Marco Cordella (Ophtalmic Clinic of Parma)have given evidence to a strong correltion between iridis colour, colour of the hair and senile degenerative maculopaties.
In a study made by Dr. Weiter (1985) on individuals affected by senile macular degeneration it has been observed that 76% of the subjects affected had fair iridis and 57% fair hair.
These frequencies, compared to a monitored group of people, showed a statistic relevant correlation between prevailing macular degeneration and colour iris (the more is clear the less is protected).
On consequency, some types of sunglasses can turn out to be dangerous if, when reducing the sunlight, do not filtrate adequately the most dangerous irradiation, that is UVA and UVB rays and high energy Blue light.Some of the most common eye deseases can be delayed by adeguated by slowing eye ageing protecting adequately from UV and Blue radiations. To postpone by 20 years such deseases would practically prevent catharat and macular degeneration, which are considered relevant causes of visual defects in the United States.

It is particularly important to sort out the most effective sun glasses with PHOTOPROTECTIVE filters, in Olent Optics are available for test the photochromatic lenses C.P.F. by Corning France, melanine lenses by Blue Blocker, Photoselector etc..
Optometric visual analysis for persons affected by visual defects costs between 50 alle 120.000 liras ( 25.82 to 61.97 Euro) depending on time necessary to analyse and solve the problem.
