Determining magnification for reading with low vision.
BACKGROUND In the past, practitioners have used distance and/or near visual acuity (VA) to calculate required magnification for low vision aids. Magnification was usually under-estimated when compared with the final magnification prescribed. Recent studies have emphasised the importance of acuity reserve in determining the required magnification for optimum reading rate. Two different approache...
متن کاملOptical magnification for subnormal vision: historical survey.
Early attempts to provide optical magnification to compensate for subnormal visual acuity used small galilean telescopes, mounted in spectacle frames, giving magnifications ranging from 1.3 to 3 ~ . They were seldom helpful in distance vision because of the restricted field, change of apparent distance, and inadequate magnification. Many used them only for reading, and obtained additional magni...
متن کاملHead mounted video magnification devices for low vision rehabilitation: a comparison with existing technology.
Background Patients with low vision typically have reduced visual acuity and a significant loss of contrast sensitivity, often in combination with visual field loss. These impairments cause a number of disabilities including diYculty with reading, writing, recognising faces, watching television, orientation and mobility, and completing activities of daily living. In a recent large scale survey ...
متن کاملCortical magnification plus cortical plasticity equals vision?
Most approaches to visual prostheses have focused on the retina, and for good reasons. The earlier that one introduces signals into the visual system, the more one can take advantage of its prodigious computational abilities. For methods that make use of microelectrodes to introduce electrical signals, however, the limited density and volume occupying nature of the electrodes place severe limit...
متن کاملVision-Based Magnification of Corneal Endothelium Frames
We present a fast and effective method to compute a highresolution image of the corneal endothelium starting from a low-resolution video sequence obtained with a general purpose biomicroscope. Our goal is to exploit information redundancy in the sequence so as to achieve via software a magnification power and an image quality typical of dedicated hardware, such as the confocal microscope. The m...
