Vision impairment or blindness may be caused by a variety of reasons. Blindness may be partial or total and can have symptoms like blurry vision, an inability to distinguish between different shapes and colours, poor vision at night, and tunnel vision as well. Being partially or completely vision impaired may be due to a head injury, glaucoma, retinal detachment, cataracts or even tumours.
HOW IS BLINDNESS DIAGNOSED?
A thorough eye exam by an optometrist will help determine the cause of blindness or partial loss of vision. The doctor will administer a series of tests that measure the clarity of vision, the function of eye muscles, and how the pupils react to light. They’ll examine the general health of eyes using a slit lamp, which is a low-power microscope paired with a high-intensity light.
HOW IS BLINDNESS TREATED?
The various forms of treatment consist of measures like eye glasses or eye lens, surgery, and medication, depending on the cause of the blindness.
DID YOU KNOW?
In case of unexplained or complete blindness that mostly occurs from birth onwards, the doctor may ask the patient to lean Braille or get take other such measures.
