What are Visual Hallucinations?

Visual hallucinations are hallucinations which involve seeing things which aren’t really there, or seeing things which appear to be real but aren’t. They can range from very simple, single images to more complex visual experiences. Common examples of visual hallucinations include seeing people or animals that are not actually present, imaginary colors or lights, and objects which move or disappear.

These hallucinations can affect any part of the visual field, such as the center, edges, or entire field of vision. People may experience hallucinations in one eye or both eyes, and they can vary in intensity over time. Visual hallucinations can be caused by various medical conditions, certain medications, drug use, and other psychological issues.

Types of Visual Hallucinations

Visual hallucinations, the perception of sight when there is nothing to actually see, can be experienced in many different forms. Different types of visual hallucinations include:

  • Faces or figures that aren't really there
  • Movement or light in a room or area
  • Seeing colors such as bright flashes and streaks
  • Halos of light and vivid patterns

These types of visual hallucinations are usually experienced in people with schizophrenia or other mental health issues, however they can also be caused by sleep deprivation, sensory deprivation, substance abuse, or certain illnesses.

Symptoms of Visual Hallucinations

When someone is experiencing a visual hallucination, they may see different things depending on the cause. They may experience flickering lights or objects, scenes that are not actually there, or distorted images. In extreme cases, people may experience full visions that last for an extended period of time.

It is important to note that visual hallucinations are not the same as other types of visual disturbances. For example, visual distortions such as blurred vision or double vision should not be confused with a hallucination. It is also important to distinguish between visual hallucinations that occur due to an underlying medical condition, and those that occur due to substance use or abuse.

If you suspect you or someone you know may be experiencing visual hallucinations, seek medical advice from a health professional immediately.

Signs to be Aware Of

When it comes to visual hallucinations, it is important to recognize the signs so that you can catch them before they progress further. Visual hallucinations may manifest in different ways and some of the signs to look out for are:

  • Vivid colors
  • Sparkles or flashes of light
  • Blurred or distorted images
  • Halos around objects
  • Hallucinatory figures
  • Seeing images from the past or future

If you notice any of these signs, it is important to talk to a doctor to assess the situation. Do not wait until it progresses further, as this could have a severe effect on your mental health.

Differentiating between Visual Hallucinations and Other Types of Visual Disturbances

Many people who experience hallucinations or other types of visual disturbances may be unsure if they’re really experiencing something abnormal. It is important to remember that there are differences between visual hallucinations and other types of visual disturbances.

Visual hallucinations occur when someone is perceiving something that is not actually present. This could involve seeing a person, animal, object, or even a whole scene that is not real. Visual disturbances, on the other hand, can involve distortions in what the individual does see.

Some common types of visual disturbances include double vision, blurriness, and blind spots. These disturbances do not involve seeing something that is not there, but instead involve some kind of distortion in what the individual can perceive. It is important to note that visual disturbances can be caused by physical health issues such as an underlying eye condition.

Seeking professional help is the best way to determine if you are having visual hallucinations or just visual disturbances. A doctor can assess your symptoms and provide a proper diagnosis, helping you determine what course of action to take next.

Substance Use and Abuse Contributing to Visual Hallucinations

Substance use and abuse can contribute to visual hallucinations. Certain drugs and medications can induce altered states of consciousness, which in turn may cause visual hallucinations. Substance use or abuse may also be a sign of an underlying mental health disorder or addiction. If left unchecked, these issues can lead to more frequent and intense visual hallucinations.

Some of the substances that can contribute to visual hallucinations include alcohol, marijuana, hallucinogenic drugs, amphetamines, cocaine, and sedative-hypnotics like benzodiazepines.

It is important to note that substance use and abuse should not be discounted as a possible cause of visual hallucinations. If a person has been using any type of drugs or alcohol, it is important to seek professional help. A qualified healthcare professional can help to identify the underlying cause and recommend treatment options.

Diagnosis of Visual Hallucinations

If you experience consistent and persistent visual hallucinations, it is important to get a professional diagnosis in order to determine the cause. When seeking medical help, your doctor may ask questions about symptoms and perform physical and neurological examinations. Additionally, your doctor may suggest laboratory tests or imaging studies, such as magnetic resonance imaging (MRI) and computed tomography (CT) scans, to properly diagnose the condition.

It is important to differentiate visual hallucinations from other types of visual disturbances. Sometimes, an ophthalmologist may be consulted to determine if there is an underlying physical disorder that could be causing your symptoms. Your doctor may also ask questions about substance use and abuse that may be contributing to your visual hallucinations.

When to Seek Professional Opinion

If you or someone you know are experiencing visual hallucinations, it is important to seek professional help. Visual hallucinations can be caused by underlying medical conditions or psychological issues, so it is important to pinpoint the root cause and receive proper treatment.

It is best to seek medical help if you or someone you know experiences any of the following:

  • Visual hallucinations that persist and worsen over time
  • Hallucinations that interfere with daily living activities
  • Extreme symptoms of anxiety or depression
  • Altered physical or mental state

If you or a loved one are exhibiting any of these signs, it’s time to contact a doctor. They can help diagnose the condition and create a personalized treatment plan.

Testing Needed to Accurately Diagnose the Cause

Seeing a medical professional for an accurate diagnosis is essential, as it will help you better understand the cause of your visual hallucinations. Your doctor may suggest multiple tests to determine the root cause. These can include physical and neurological examinations, as well as blood and imaging tests.

There are a few common tests used to diagnose visual hallucinations, such as:

  • Neurological and physical examinations - these may include tests such as urine sampling, analysis of the reflexes, and cognitive assessments to help rule out any underlying medical issues.
  • Blood tests - these involve testing the blood for any underlying health conditions such as infections, or any nutrient deficiencies that may be causing the visual hallucination.
  • Imaging tests - imaging tests such as MRI scans, computed tomography (CT) scans, and PET scans can help detect any abnormalities in the brain that may be contributing to your visual hallucinations.

These tests are important in helping your doctor make an accurate diagnosis, so they can properly treat the underlying condition causing your symptoms.

Treatment Options for Visual Hallucinations

Visual hallucinations can be frightening and overwhelming, but there are many treatments available to those who suffer from them. Depending on the underlying cause of the hallucinations, treatment will vary.

Psychological therapy is one of the most common treatments for visual hallucinations. A therapist or counselor can work with you to develop coping strategies, talk through and process any difficult emotions, and provide guidance to help you manage your condition. Cognitive-Behavioral Therapy (CBT) is one type of therapy that has been shown to be effective in helping people manage their hallucinations.

Medication can also be used to reduce the severity of visual hallucinations. Antipsychotic medications and antidepressant medications are some of the most commonly prescribed for people suffering from visual hallucinations. It is important to find the right medication and dosage for your particular condition, as these medications can have serious side effects.

There are also a number of alternative therapies that may help reduce symptoms and improve quality of life for those with visual hallucinations. Meditation, acupuncture, yoga, and other relaxation techniques can all be beneficial in helping to manage the symptoms. Additionally, dietary changes and the use of supplements can also help reduce the frequency of hallucinations.

Psychological Therapy for Visual Hallucinations

Psychological therapy can provide a person with the tools to help cope and manage their symptoms associated with visual hallucinations. There are different types of therapy techniques available to meet individual needs. The most popular types of therapies are Cognitive Behavioral Therapy (CBT) and Dialectical Behavior Therapy (DBT).

Cognitive Behavioral Therapy (CBT) is a type of psychotherapy that focuses on helping people identify and change patterns of thinking, feeling, and behaving that are causing distress. CBT helps patients develop healthier ways of coping with stress, anxiety, fear, and other symptoms associated with visual hallucinations.

Dialectical Behavior Therapy (DBT) is a form of CBT that helps patients learn how to regulate their emotions. DBT teaches effective skills for problem-solving and managing difficult emotions. By learning these skills, patients are better able to identify, understand, and manage the symptoms associated with visual hallucinations.


Medication is sometimes recommended to manage visual hallucinations in more serious cases. Many medications are used, but the most common are antipsychotics and anticonvulsants. Antipsychotics are used to treat the symptoms of psychotic disorders like schizophrenia, while anticonvulsants are used to help control the episodes of hallucinations.

It is important to discuss any medications you take with your doctor and do not start taking any without their approval as they can have serious side effects. Common side effects include dizziness, nausea, headaches, drowsiness, dry mouth, weight gain and restlessness.

In some cases, medication might be prescribed in combination with psychological therapy to maximize its effectiveness. If you are prescribed medication, it is important to take it as advised by your doctor and attend all follow-up appointments.

Other Alternative Therapies

Visual hallucinations can be treated with more than just medication and psychological therapy. There are several alternative therapies that have shown promising results in helping to manage visual hallucinations.

Some of these therapies include art therapy, music therapy, and horticultural therapy. Art and music therapies involve activities such as drawing, painting, or playing a musical instrument. They’re designed to help the individual express their feelings and emotions in a safe and calming environment. Horticultural therapy involves gardening or other outdoor activities that may help reduce stress in individuals with visual hallucinations.

Alternative therapies may also involve meditation, mindfulness, and yoga. These activities can help improve physical and mental wellbeing, which can ultimately lead to fewer visual hallucinations. Hypnosis is another option, where a trained therapist guides an individual into a relaxed state and helps them address any underlying mental or emotional issues that could be contributing to their visual hallucinations.
