- Central vision loss (blind at the mid-point of vision)
- Peri-periodic vision loss (blind out of those corners)
- Nighttime blindness (blind in the event of dim lighting)
What are the causes of low vision?
There are many causes that could cause visual impairment, such as diabetes retinal disease and advanced age macular degeneration, and glaucoma. Certain diseases like damage to the optic nerve or retinal detachment could result in permanently lost vision.
Other causes, such as hyperopia or myopia dystrophies of the corneas, cataract surgery injuries, and inflammation of the eye may cause blurriness that lasts for a long time and double-vision.
