Low vision solutions, demonstrations, magnification and advice to suit you.

mobilent

Digital magnifier  high definition screen allows more flexible  working distances that suits each individual compared with optical magnifiers set distances. They can feature  large tactile buttons with magnification ranges from 1.7x to 12x, true colour and contrast enhancement modes. 

The Mobilent LED is a folding pocket magnifier that offers high magnification (4X, 7X or 10X) in a compact size with added LED illumination. Its built-in case is designed to provide complete protection for the lens when not in use.  The quick-release clasp on the lanyard allows the magnifier to be easily unhooked when needed. The Mobilent LED is ideal for near spotting tasks such as reading price tags, prescriptions, labels and more. Due to its compact size, it fits easily into a pocket or purse and is ideal for magnifying small print discretely. 

We can help with simple and specialised optical and digital magnification,portable hands free ,occupational and hobby magnifiers.
New digital magnifiers  with seamless zoom from 2-22X, allows for line scrolling,speech assistance and the ability to write underneath and allowing to be connected to a monitor via HDMI for greater magnification (12-125x on a 1016mm TV).  Digital magnifier  high definition screen allows more flexible  working distances that suits each individual compared with optical magnifiers set distances.

Telescopes, Bioptics for driving

Driving with Bioptics
Bioptic telescopes can help eligible visually impaired individuals sometimes obtain a driver’s license and be safer drivers.

 The bioptic telescope allows them to see the target sooner, giving the driver more time to react. In practice, the telescope increases the individual’s ability to see further forward by a factor of the power of the device. For example, a 3x telescope will allow the user to see a sign at 18 metres  through their bioptic, while they would only be able to see it at 6 meters  feet with their normal vision- 3 times further away.

Drivers using bioptics  normally see through their regular glassses but utilise the telescope function for short periods of time in a similar fashion to using  rear and sideview mirrors.

galilean telescope spectacles

Galilean telescopes  are smaller and lightweight offering about 5 degrees  of field at 4x. Normally 1.7x and 2.2x are used

keplerian-telescope-spectacles

Keplerarian telescopes are longer and heavier offering about 12 degrees of filed at 4x. Normally 3x,4x,5x and 6x are used

The Ocutech VES Falcon Bioptic Telescope is the world’s only autofocusing bioptic for the visually impaired.   ​

ORCAM TECHNOLOGY

OrCam technology responds to hand gestures and allows

  • Reading of Text
  • Facial Recognition and identification of shopping products
  • Portable and magnetically mounts onto eyeglass frame.
  • Wireless technology and not require an internet connection.
  • More than 20 voice-activated commands available
  • Bluetooth connectivity and barcode recognition.

Esight for legally blind

A wearable electronic aid that assists the legally blind to actually see  in a bioptic manner,not drive though. Most other devices using VR/AR headsets completely immerse the wearer in that view, at the expense of  peripheral awareness and  mobility. Esight is actually trying to improve the vision of people with some remaining vision from about 6/24 to 6/180 even to 6/240. The Seeing AI app  attempts to read  out text and  describe scenes ie  by pointing  a suitable  smart phone to enable  descriptions .
Electronic mobility aids: Orientation devices:  Act  by sending out ultrasonic beams and  providing  vibratory or auditory feedback to the user when it detects an obstacle. GPS devices:  Global Positioning System (GPS) with  software can be operated through an accessible mobile phone (with speech software) or can be incorporated into a white cane.

CHOOSING THE CORRECT BINOCULAR

birdwatching binocular

The right binocular for any use can be found. From a simple monocular that fits in your pocket to twilight binoculars.
The quality of the optics, the types of coatings applied to the lenses, the housing material all vary widely akin to the case in spectacles.

All binoculars are identified by a set of numbers, such as 10×42 and 7×20, which refer to their magnification and objective lens diameter, respectively. Using 10×42 as an example, the 10x means that the binoculars have 10x magnification power, making the view through them appear 10 times closer than it appears to the naked eye.

 

Binoculars (being more comfortable than a monocular) use lenses and prisms to produce a magnified view of distant objects or scenes.
Prisms are used to correct the orientation of the view horizontally and vertically whereas the human brain does this to a focused image.
The elements in the more compact roof prism are in line with one another unlike those offset from one another in Porro prisms.
Porro prism binoculars are typically more cost-effective to produce than roof prisms.
Binoculars from 7x to 10x power are the most commonly used. Tripods are used with higher magnifications or larger objectives as in cameras
The higher the magnification, the smaller the field of view.
Larger objectives though heavier allow more light to pass through them than smaller lenses, which means images will appear brighter, sharper, and clearer.

Zoom binoculars offer variable magnification with some loss in image brightness and sharpness. To see the exit pupil, hold the binocular away from your face and notice the small dots of light in the center of the eyepieces. Binoculars exit pupil diameter is determined by dividing the objective by the magnification: so a 10×42 binocular has a 4.2mm exit pupil diameter which is desirable as bigger than the average pupil. Manufacturers install eyecups on the eyepieces to place the user’s eyes at the proper distance from the eyepieces.

BAK4 Barium Crown glass is considered the best type of prism material though BK7 glass is arguably the most widely used material for binoculars.SK15 glass is also sometimes used. Lens coatings are thin films applied to lens surfaces to reduce glare and reflections, increase light transmission and contrast, and brighten colours. Coated lenses are the most basic and denote that at least one lens surface has at least one layer of coating on it. Multi-coating refers to multiple layers applied to each surface. Fully multi-coated means that all surfaces—inner and outer—of the lenses have multiple layers applied to them. This treatment offers the highest level of light transmission, clarity, contrast, and colour rendition. These coatings are engineered to be effective across a wide spectrum of wavelengths and provide the best performance. Prism Coatings may use standard reflective coatings, or dielectric coatings, which allow almost 100% of the light through the prism, resulting in brighter high-contrast images.

Phase-correcting coatings can be  used in roof prisms. Most binoculars have the main focus wheel set on the bridge to move the two oculars symmetrically. Many binoculars have no weatherproofing, while some are waterproof and others are waterproof and fog proof by filling with inert gases to prevent fogging. The aluminum chassis are the most popular or the lighter magnesium or polycarbonate. 
Some binoculars have even integrated compasses, cameras, infrared viewfinders.

Eyecups position the eye at the proper distance and are often with wraps around the eye socket to block stray light. Digiscoping is where adapters eg on phones which allow photos of the magnified view.

ROYAL BLIND SOCIETY

The Royal Society for the Blind (RSB) Australia provides services to Australians who have a severe vision impairment.
The UK Royal National Institute of Blind People is the UK equivalent and has been establised since 1868. ​

World Braille Day 3 January is celebrated every year on Louis Braille’s birthday, the inventor of braille. 
Australian $5, $10 and $50 notes now have a tactile feature to help meet the needs of the vision impaired community.
