A person with total blindness won't be able to see anything. But a person with low vision may be able to see not only light, but colors and shapes too. You might have a blind spot or a blurry spot in the middle of your field of vision. Or your peripheral vision may be impaired on one or both sides.
Yes, Blind People Dream, Too. Blind people can and do dream, though their dreams can be somewhat different from those of sighted people. But more recent research suggests people who are blind, from birth or otherwise, can still experience visual images in their dreams.
No. While Non-24 is believed to affect over half of all totally blind individuals, it does affect some sighted people as well. However, the underlying causes are different, and these should be seen as two distinct disorders: Blind Non-24 and Sighted Non-24.

Keep in mind that Non-24 is considered a disability under the Americans with Disabilities Act. Schools and employers must make reasonable accommodations for you, such as part-time or altered schedules.
Non-24-Hour Sleep Wake Disorder (Non-24) is a disorder that affects the normal 24-hour synchronization of circadian rhythms. One subtype designation according to the International Classification of Sleep Disorders is Circadian Rhythm Sleep Disorder - Free Running Type.
Vanda Pharmaceuticals is committed to making HETLIOZ® (tasimelteon) accessible to people living with Non-24-Hour Sleep-Wake Disorder. HETLIOZSolutions™ was created to support people who have been diagnosed with Non-24.
VANDA 20 mg (Hetlioz 20 mg)
It is supplied by Vanda Pharmaceuticals Inc.. Hetlioz is used in the treatment of non-24-hour sleep wake disorder; insomnia and belongs to the drug class miscellaneous anxiolytics, sedatives and hypnotics.Hetlioz (tasimelteon) is a sedative, also called a hypnotic. It works by affecting certain substances in your body that help regulate your "sleep-wake cycle." Hetlioz is used to treat non-24-hour sleep-wake disorder.
Hetlioz (tasimelteon) received FDA approval in 2014 as a melatonin receptor agonist indicated for the treatment on Non-24-hour sleep wake disorder. During trials, both animal and human, tasimelteon did not show any signs of abuse potential or dependence; as such tasimelteon is not a controlled substance.
Because they don't perceive light at all completely blind people have no way of knowing if its day or night. This completely messes up their sleep schedules. The circadian rhythm is an internal clock that tells our body when to sleep. It relies on cues from sunlight to stay on track.
Kleine-Levin Syndrome (KLS), also known as “Sleeping Beauty” syndrome, is a rare neurological disorder characterised by recurrent bouts of hypersomnolence (excessive sleeping) along with cognitive and behavioural problems during wakefulness.
You could also get Non-24 if your body doesn't make enough melatonin. Other causes include: Developmental brain disorders, including autism spectrum disorder. Brain damage from head injury or tumors.
Too much sleep on a regular basis can increase the risk of diabetes, heart disease, stroke, and death according to several studies done over the years. Too much is defined as greater than nine hours. The most common cause is not getting enough sleep the night before, or cumulatively during the week.
Circadian rhythm sleep disorders. Circadian rhythm sleep disorders occur when the circadian clock in the brain, which drives daily behavioural and physiological rhythms, is not synchronised with 'real' local time. This can result in abnormal sleep patterns, sleep loss and fatigue.
Emsellem says that Non-24 is a very rare condition affecting many (but not all) people who are totally blind and have absolutely no light perception. Their circadian clocks become out of sync as a result. People with Non-24 have trouble going to sleep at night and staying awake during the day.
Thankfully, there are treatments available that you can talk to your patients about for the five most common sleep disorders:
- Insomnia.
- Sleep Apnea.
- Narcolepsy.
- Restless Legs Syndrome.
- and REM Sleep Behavior Disorder.
Insomnia. Insomnia, the inability to get to sleep or sleep well at night, can be caused by stress, jet lag, a health condition, the medications you take, or even the amount of coffee you drink. Insomnia can also be caused by other sleep disorders or mood disorders such as anxiety and depression.
Non-24 is common in totally blind people due to the lack of light information received from the eyes, which normally regulates the 24-hour day-night cycle. Reports suggest that as many as half to three-quarters of totally blind patients have Non-24, representing approximately 65 to 95 thousand Americans.
