A person is said to have low vision when their eyesight is limited or impaired and cannot be corrected with conventional glasses or contact lenses. They have a visual acuity of less than 6/18, or they have a visual field of less than 20 degrees across. People are not legally allowed to drive with these vision measurements. Vision tests are conducted by eye care specialists, who include: optometrists, ophthalmologists and orthoptists. If you have been diagnosed with an eye condition and you have been advised by your eye care specialist that you are still allowed to drive, we can still provide you with information about services that may be of benefit now or in the future, if your vision deteriorates.
RGDT also provides services to people who have lost vision as a result of eye disease or trauma, acquired brain injury, congenital conditions and stroke.

The names of some eye conditions are difficult to pronounce and you may be confused by the terminology used by your eye care specialist. Sometimes families and friends may have trouble understanding the impact of your vision loss. RGDT can help explain your eye condition to you and your family using easy to understand terms and can provide links to relevant resources. Our services do not replace a consultation with your eye care specialist, but we can assist people to further understand their diagnosis and prognosis in preparation for the next visit to their eye care specialist.
As part of our services, you may be referred to a Low Vision Clinic (LVC) in Hobart or Launceston. At the LVC, an optometrist experienced in assessing people who have eye conditions that cause low vision will assess your ability to read and determine whether optical and/or video magnification aids could help you. This consultation should be in addition to regular visits to your optometrist, but will provide a valuable opportunity to find out about your eye condition diagnosis, as well as strategies for improving lighting and reducing glare.
For various reasons, some people may prefer not to admit that they have vision impairment and may try to hide it. They may fear becoming a burden on family, being perceived as disabled, or being treated differently by friends, family or work colleagues. Our staff can work through some of these issues with you, if you would like them to. Adjusting to vision loss can be an emotional and stressful process, often made more difficult if your eye condition is untreatable, degenerative or hereditary.
Vision loss may be caused by disease or trauma affecting the eye and/or the brain.
