Yes, some people are completely blind (no light perception), but it's less common than partial blindness, with only about 15% of people with vision loss experiencing total blindness, while the majority have some remaining sight, ranging from blurry shapes to light perception. Total blindness, termed "no light perception" (NLP), means no sight at all, but people born blind don't see blackness but rather nothing, while those who lose sight later might see flashes or experience hallucinations, notes Perkins School For The Blind and The American Foundation for the Blind.
Total blindness is the complete lack of light perception and form perception and is recorded as “NLP,” an abbreviation for “no light perception.” Few people today are totally without sight. 85% of all individuals with eye disorders have some remaining sight; approximately 15% are totally blind.
Most blind people have some level of vision, but what they can see differs from person to person. Some may only see light. Others may see blurry shapes, figures, or colors. People with total blindness cannot see anything, but it is a misconception that they only see black or darkness.

Total blindness (no light perception) is often due to: Severe trauma or injury. Complete retinal detachment. End-stage glaucoma.
A specialized eye chart can also give you more precise results between 20/100 and 20/200. Visual acuity between 20/200 and 20/400 is classified as severe vision loss, and anything below 20/400 is considered profound vision loss.
There is currently no cure for blindness. However, there are forms of treatment and preventions that patients can use to attempt to restore vision and prevent further damage to their eyes. The type of blindness treatment a patient seeks will depend on the cause and course of their blindness.
During a 2018 interview with Rolling Stone magazine, Johnny Depp disclosed that he is blind in his left eye and short-sighted in his right eye! Whilst filming Pirates of The Caribbean, Johnny admits that he could barely see a few inches in front of his face… how disorientating.
Legal blindness is defined as having 20/200 vision or less. This means that an object that appears clear to a person with a perfect vision from 200 feet away, is only clear to a legally blind person at a maximum distance of 20 feet away. Legal blindness is also defined as having a visual field of 20 degrees or less.
Humans are blind for about 40 minutes per day because of Saccadic masking—the body's way of reducing motion blur as objects and eyes move. An eye care provider conducts a thorough eye exam to ensure that these components are functioning well together.
Recovery from blindness is the phenomenon of a blind person gaining the ability to see, usually as a result of medical treatment.
Most blind people's eyes look just like sighted people's eyes. The appearance of the eye depends on the cause of blindness. Some conditions may change how the eye looks, but many don't affect appearance at all.
Cataract. Cataract is a clouding of the eye's lens. It's the leading cause of blindness worldwide and the leading cause of vision loss in the United States. Cataracts can occur at any age and can be present at birth.
In the early stages of DR, a person may not experience any symptoms. Others may experience symptoms such as having trouble reading or seeing objects that are far away. These changes may come and go. In the later stages of DR, a person may see floating spots or streaks in their vision.
People who experience total darkness all the time have “total blindness,” whereas those who may be able to see some light, colors, or shapes are commonly referred to as having “low vision.” You may have a blind spot or blurry area in the center of your field of vision. Or your peripheral vision may be impaired.
Even if they try to sleep at regular times, they typically sleep well only a few days a month, when their internal clocks fall in sync with preferred schedules. At other times, they sleep poorly and feel drowsy while awake.
Actual answer: they fold the toilet paper to test if it sticks to itself. If it does, they're not done wiping.
The rarest eye colors are red and violet, typically seen in people with albinism due to a lack of melanin, followed by green eyes, which occur in only about 2% of the global population, making them the rarest common color, and grey eyes, often mistaken for blue but distinct, also very rare. Conditions like heterochromia (different colored eyes) are also exceptionally rare, while brown is the most common.
By the 2010s, Depp's front teeth had suffered significant wear and decay. He had reportedly lost most of the enamel on those teeth, leaving the underlying dentin exposed and yellowed. As a result, his front teeth looked much darker and shorter than before, with visible brown spots indicating decay and old fillings.
Back in September of 2024, Elton John shared on Instagram that he was recovering from an eye infection that had left him with limited vision in one eye.
Harnessing the powerful capabilities of AI machine learning with innovative hardware devices may be an effective way to restore vision for one of the leading causes of irreversible blindness. This pioneering research is paving the way for those suffering from irreversible blindness to see once again in the future.
Leber congenital amaurosis can cause total blindness or severe sight loss from birth or early childhood.
Sudden loss of vision can occur for a number of reasons. Many underlying problems are very serious and could potentially be sight-threatening or even life-threatening. It is therefore important to seek medical help as soon as possible if you experience any sudden loss of sight.
