Visual Acuity is the degree or clarity of vision. It is dependent on optical and neural factors, like the sharpness of the retinal focus within the eye, the health and functioning of the retina, and the sensitivity of the interpretative power of the brain. While static visual acuity for identifying a stationary target is one of the basic visual functions, there are many other important visual functions. In particular, the visual function designed to identify moving targets has been examined by a considerable number of researchers.
Visual acuity is a measure of the spatial resolution of the visual processing system. Visual acuity depends upon how accurately light is focused on the retina, the integrity of the eye's neural elements, and the interpretative faculty of the brain. Dynamic visual acuity (DVA) is a relatively independent parameter for evaluating the ability to distinguish details of a moving target. The present study has been designed to discuss the extent to which age-related cataract impacts DVA in elderly individuals and to determine whether it could be restored after bilateral phacoemulsification combined with intraocular lens implantation surgery.
A common reason of low visual acuity is refractive errors. To determine whether a person has low visual acuity or not certain Dynamic Visual Acuity Test are done and related remedial measures such as Dynamic Visual Acuity Exercises are prescribed by the doctor. The impact of age-related cataract on DVA is found to be more severe than its effects on static visual acuity. After cataract surgery, not only static vision of the patients was restored markedly, but also the dynamic vision. DVA could be an important adjunct to the current evaluation system of functional vision, thereby meriting additional attention in clinical assessment.
