All About Low Vision

Low vision comes as a visual impairment that may not be rectified with glasses, surgery, or contact lenses, but low vision can be corrected with LASIK laser eye surgery. An eye doctor from Sugarland Eye & Laser Center in Houston can help identify the range of treatment options available for vision improvements.  Low vision can be classified as the following:

Progressive reduction of best-corrected visual acuity to a range of 20/70 and even lower in the eye which sees best. 
Reduction of visual field. Loss of periphery vision resulting in tunnel vision. The patient experiences blind spots which can indicate loss of field vision. 

Vision Loss Patterns
Central Vision 
When a person looks at something, they use their central vision to get the details of what they’re looking at. Central vision becomes commonly affected by macular degeneration. Diabetic retinopathy can also affect central vision in addition to peripheral vision. 
Peripheral Vision 
This vision sees objects around the central vision. People use the edges of their eyes for this purpose. Peripheral vision becomes affected by the eye disease known as glaucoma. Strokes can affect peripheral vision as well. 
Contrast Sensitivity
This is the ability a person has to distinguish contrast in objects. This includes identifying milk in a cup to understanding the differences in facial features of people. Vision loss affects contrast sensitivity and can even reduce it. 
Depth Perception
Depth perception is a person’s ability to judge the depth of objects. Vision loss in either eye can affect this judgement skill. For instance, the person might not be able to judge the height of a step instantaneously and may be overly cautious going up and down stairs. 
Visual Processing
The visual process in the eye starts with the lens concentrating light rays on the retina which in turn converts those light rays into signals which become transmitted to the brain’s optic nerve. The brain interprets it as images. A problem in such processes will affect the way a person sees objects. 
Symptoms of Vision Loss

Strabismus also called crooked eye
Pupils always in a state of dilation or not responding to light
Eye discharge

The loss of vision can be treated with LASIK laser eye surgery or other types of treatment depending on the underlying eye condition. The patient can call upon the services of qualified eye surgeons of premier eye clinics such as Sugarland Eye & laser Center in Houston. Vision loss may indicate a more serious problem.
