Some people are almost blind without regular glasses and contact lenses, whereas some have low vision problem and they look for solutions to check losing the sight further.
The causes of deterioration in eyesight are not very rare to find and many individuals around us can be seen with glasses and contact lenses. Some people find it difficult to sight an object after putting off their thick glasses. This is the condition of low vision that can simply make your everyday tasks difficult. Difficulty in sighting can pose serious challenges to accomplish daily activities like driving, reading, sewing, writing, watching TV, viewing pictures, identifying faces and colors etc. There are millions of people living with different stages of vision impairment. It is estimated that more than 14 million people with low vision are living only in America.
Measurement of vision:
The ratio measurement of vision defines the condition of visual acuity, or the health of your vision, at 20 feet from an object. For example, if you are having 20/60 vision than it means you must be at 20 feet to see an object that a person with normal vision can see at 60 feet.
As per the intensity of visual impairment, the World Health Organization has come up with some types of eyesight loss, such as:
• 20/30 to 20/60 is a mild vision loss, or almost normal eyesight
• 20/70 to 20/160 indicates moderate visual impairment
• 20/200 to 20/400 is considered severe visual impairment
• 20/500 to 20/1,000 is considered profound visual impairment
• Less than 20/1,000 is a condition of near-total visual impairment/blindness
• No perception or reaction to light is considered as total visual impairment, a condition of blindness
Some common types of partial vision loss are known as:
• Loss of central vision
• Loss of side or peripheral vision
• Light sensitivity
• Night blindness
• Blurred vision
• Hazy vision
Causes of vision loss:
Low vision can be caused by a variety of conditions and injuries and age. Besides age-related retinal conditions, there are many other possible conditions like macular degeneration, cataracts, glaucoma, corneal opacification, eye cancer, eye trauma, genetic defects, brain injury, stroke, albinism etc. that cause vision problems. People above of 45 witness these problems more often.
Macular degeneration is the most common problem that directly affects the retina, causing light sensitive lining at the back of the eye. The deterioration in macula causes blurred vision and it’s very common in old people.
Blindness or low vision can occur in combination with some other health conditions such as autism spectrum disorders, cerebral palsy, intellectual disability, hearing impairments, and epilepsy.
