Hemianopia, also known as Hemianopsia is loss of vision in either the whole left or the whole right half of the field of vision. The most common causes of this damage include the side effect of stroke, brain tumour and trauma. Such vision loss could lead inconveniences in life for instance problems with mobility, tendency to bump into objects, falling incidents, unpredicted accidents and reading difficulties.

Results from the National Health and Nutrition Examination Survey (1988-1994) indicated that 1 in 1000 people examined had Hemianopia. At least one third of stroke survivors in rehabilitation have either homonymous Hemianopia or spatial neglect. 

If you have found this website we are assuming that you, or your loved one, or a client has been diagnosed with Hemianopia. You just ignited a new hope! What you are reading now are actually the treatment options available in Malaysia to help the Hemianopic patients.

1.  The Peli Lens™, the newest and most effective prism technique that offers more field expansion than any other option; by far: 20˚ in the original design and 30˚ in the new design. These are backed by clinical trials.

2.  Training to scan (vision therapy)

Based on clinical research, patient success rates, field expansion characteristics and cost, the Peli Lens™ represents the best option for a majority of hemianopic patients.  The other methods mentioned here are viable options in the event that the patient does not adapt to the Peli Lens™.

Hemianopic View (Right Blindness)What will be missedThe Peli lens™or“EP” Expansion Prism Lens


A hemianope who has vision only on the left side of both eyes would likely trip over the trash bin because it is not visibleIf we could somehow indicate to the hemianope that there is an obstacle in his blind field, then it could be avoided.


The "EP" or Expansion Prism system.
The "EP" system is designed to help with obstacle detection, especially while moving; it is not a reading aid.
Patient fitting is simple and cost effective using the fitting protocol provided and making adjustments as needed during the training walk with the patient.  The patient then is sent home to adjust for about one month.
