What is causing a disturbance in my vision

Have you ever wondered why your vision doesn’t seem as clear? What exactly are these disruptions to our vision, and why do they happen? If you cannot see clearly through your eyes, it’s because of vision disturbance.

Do you know what is called visual disturbance? A visual disturbance is anything that messes with your ability to see clearly and comfortably and can be quite a bother. It affects more than half of the world’s population, but why does it happen? Let me tell you there are six typical eye conditions responsible for these disturbances.

In this article, we will explain vision disturbance and its causes and many more, so keep reading.

Types of visual disturbance

There are six common types of visual disturbance, such as:

1: Colour blindness

People suffering from colour blindness can’t see the light the way normal people can. Some people having poor colour vision are partially colour blind. They are unable to differentiate between different colours.

Total colour blindness is not so common. Completely colourblind people can see only shades of grey.

Causes of colour blindness

Men are more affected by colour blindness as compared to women. The most occurring form is red-green colour deficiency. The following are the different causes of colour blindness:

  • Increasing age
  • Diabetes
  • Glaucoma
  • Hereditary
  • Different medications like antihypertensiv and anticonvulsant
  • Exposure to different chemicals
  • Anemia
  • Optic neuritis

2: Blurred vision

Blurred vision can be due to a change in eyesight or any other underlying condition. If eyes are not normally aligned, then they can’t receive and read visual messages.

3: Double vision

Double vision is known as diplopia. It is a condition when everything appears double to you. It can indicate any serious health problem. If you suffer from these symptoms, you must consult your doctor.

There are two different types of diplopia:

  • Monocular

Double vision affecting only one eye is known as monocular diplopia. It can be due to physical changes to the lens over your eyes, retina or cornea. This occurs with only one eye open.

  • Binocular

Poorly aligned eyes can lead to binocular double vision. In this condition, both eyes are affected. It can be the result of any damage to the nerve.

Causes of double vision

There are the following possible causes of double vision:

  • Myasthenia gravis, an autoimmune condition that causes the weakening of eye muscles
  • Cataract
  • Scarring or infection of the eyes
  • Diabetes
  • Hypertension
  • Trauma to eye lens and cornea
  • Fatigue of eye muscles
  • Nerve conditions like multiple sclerosis and guillain barre syndrome

4: Partial blindness

Partial blindness is a condition in which you can see light and some degree of what’s around you.

If someone has vision below 20/200 are completely blind people.

In some cases, you can correct it with the following things:

  • Glasses
  • Surgery
  • Contact lenses

Causes of blindness

There are following different causes of blindness:

  • Cataract
  • Diabetes  
  • Glaucoma
  • Stroke
  • Tumors
  • Inflammation of eyes
  • Macular degeneration
  • Hereditary reasons

5: Halos

Halos mean appearing circles of light around things. They indicate any other eye problem that needs proper checkup and consultation.

Causes of halos

 Halos occur due to:

  • Cataract
  • Glaucoma
  • Migraine trauma to the eye’s cornea
  • Ocular migraine
  • Pain

There are different reasons for eye pains. Few are the following:

  • Glaucoma
  • Bacterial infection
  • Pink eye or conjunctivitis
  • Infection due to contact lenses
  • Trauma to the eyelid
  • Sinusitis

6: Pain

Eye pain varies with different conditions. It feels like a scratching sensation when you open or close your eyelid. Pain can be mild or sharp depending on the condition.

How to diagnose?

If you feel any eye problem appearing suddenly and abruptly, you must see a doctor ASAP. Vision disturbance can occur due to any other medical problems like:

  • Brain tumours
  • Glaucoma
  • Stroke
  • Aneurysm

Your doctor will see you and perform different tests to confirm the diagnosis:

  • Physical checkup
  • Eye exam
  • Blood tests
  • Imaging tests like MRI and CT

Who is at risk of visual disturbance?

Many conditions can make you more prone to problems related to the eyes. These conditions are the following:

  • Diabetes
  • Migraine
  • Macular degeneration
  • Cataract


The first step of eye problem treatment is to find out the actual underlay cause. After figuring it out, the doctor can make the whole treatment plan.

Sometimes, it subsides without any treatment; for instance, blurry vision caused by a headache resolves independently. But a doctor can prescribe you medication for future prevention.

  • Medication

 Sometimes, you can treat eye problems by taking some medications.

  • Dietary changes

Sometimes you need to change your lifestyle, mainly your diet. Because eye health highly depends on your diet. Add the substances in your diet which are good for your health.

  • Glasses, contact lenses

These are the temporary options when all other treatments can’t cure them.

  • Surgery

You can also cure your vision problems with the help of surgery.

Final words

Different conditions and medical problems lead to visual disturbance. These disturbances can develop at any time. If you feel any visual problems, seek your doctor’s advice immediately. Some eye problems are permanent, while others are temporary and can be cured with the help of medicine.
