Vision loss after a stroke is more common than many people realise. A stroke can affect how your brain processes visual information, leading to blurred vision, loss of part of your visual field, double vision or difficulty recognising objects. Learn why it happens, what symptoms to look for, and how rehabilitation may help.

After your stroke...

Something doesn't feel right.

You bump into door frames.

You miss objects on one side.

Reading becomes difficult.

People seem to appear from nowhere.

You begin wondering...

"Is there something wrong with my eyes?"

Sometimes...

Your eyes are perfectly healthy.

The problem is that your brain is struggling to process what your eyes are seeing.

Vision changes are one of the most common effects of stroke.

The Good News

Many people experience improvements in their vision after a stroke.

Others learn practical strategies that help them adapt and live independently.

Early assessment and rehabilitation can make a significant difference.

Recovery often continues over many months.

✦ ✦ ✦

Can a Stroke Cause Vision Loss?

Yes.

A stroke can damage the areas of the brain responsible for processing vision.

Although your eyes may still work normally, the brain may no longer interpret visual information correctly.

This is why some people experience vision problems even when an eye examination appears normal.

✦ ✦ ✦

Types of Vision Problems After a Stroke

Vision changes vary depending on which part of the brain has been affected.

Visual Field Loss (Hemianopia)

One of the most common problems is losing vision on one side.

You may:

✓ Miss objects on one side.

✓ Walk into furniture.

✓ Miss words while reading.

✓ Leave food on one side of your plate.

Many people don't realise part of their vision is missing because the brain fills in the gaps.

✦ ✦ ✦

Double Vision (Diplopia)

Some strokes affect the muscles that control eye movement.

This may cause double vision.

You may see:

✓ Two images instead of one.

✓ Blurred vision.

✓ Difficulty judging distances.

Double vision may improve as recovery continues.

✦ ✦ ✦

Blurred Vision

Blurred vision can occur for several reasons after a stroke.

It may affect one eye or both and can make reading or recognising faces more difficult.

✦ ✦ ✦

Visual Neglect

Visual neglect is different from vision loss.

Your eyes may be able to see both sides.

However, your brain pays little or no attention to one side of the world.

For example, you may:

✓ Ignore food on one side of your plate.

✓ Only shave or apply makeup to one side of your face.

✓ Bump into objects on one side.

Visual neglect is an attention problem rather than an eyesight problem.

✦ ✦ ✦

Difficulty Recognising Objects or Faces

Some strokes affect the brain's ability to recognise familiar objects, faces or places, even though vision itself is intact.

This can feel confusing and frightening.

✦ ✦ ✦

Symptoms of Vision Problems After Stroke

You may notice:

✓ Blurred vision.

✓ Missing part of your vision.

✓ Double vision.

✓ Difficulty reading.

✓ Bumping into objects.

✓ Difficulty judging distances.

✓ Losing your place while reading.

✓ Increased sensitivity to light.

✓ Difficulty recognising faces.

Symptoms vary depending on the area of the brain affected.

✦ ✦ ✦

How Are Vision Problems Diagnosed?

Assessment may include:

✓ Eye examination.

✓ Visual field testing.

✓ Eye movement assessment.

✓ Reading assessment.

✓ Functional vision assessment.

You may be assessed by an ophthalmologist, orthoptist, optometrist or neuro-rehabilitation team.

✦ ✦ ✦

Treatment and Rehabilitation

Treatment depends on the type of vision problem.

Vision Rehabilitation

Specialist therapists may provide exercises and techniques to improve visual scanning and awareness.

✦ ✦ ✦

Scanning Training

People with visual field loss often learn to deliberately scan towards their affected side.

This helps reduce collisions and improves safety.

✦ ✦ ✦

Prism Glasses

Some people benefit from special prism lenses that help compensate for visual field loss.

Your eye specialist can advise whether these are suitable.

✦ ✦ ✦

Eye Movement Exercises

If eye muscles have been affected, specific exercises may help improve coordination and reduce double vision.

✦ ✦ ✦

Practical Adaptations

Simple changes can make everyday life easier.

These may include:

✓ Good lighting.

✓ Large-print books.

✓ High-contrast colours.

✓ Keeping rooms free from clutter.

✓ Turning your head more towards the affected side.

Small adjustments often make a big difference.

✦ ✦ ✦

Safety Tips

Vision changes may increase your risk of accidents.

Try to:

✓ Move slowly in unfamiliar places.

✓ Scan your surroundings before walking.

✓ Keep pathways clear.

✓ Use good lighting throughout your home.

✓ Ask for support when needed.

Safety should always come first.

✦ ✦ ✦

When Should You Seek Medical Advice?

Seek medical advice if:

✓ Your vision suddenly becomes worse.

✓ You develop new double vision.

✓ You lose part of your vision suddenly.

✓ You notice new neurological symptoms.

✓ Vision problems are affecting your safety.

Sudden changes in vision should always be assessed promptly.

✦ ✦ ✦

My Perspective

Vision problems can be incredibly frustrating because they affect almost everything you do.

Reading.

Walking.

Cooking.

Driving.

Even recognising people.

The important thing to remember is that you're not imagining it.

Vision changes after a stroke are real.

With time, rehabilitation and practical strategies, many people regain confidence and learn effective ways to adapt.

Frequently Asked Questions

Can Vision Improve After a Stroke?

Yes.

Some people experience significant improvement, while others learn strategies that help them adapt successfully.

✦ ✦ ✦

Can My Eyes Be Healthy But My Vision Still Be Affected?

Yes.

The problem is often within the brain rather than the eyes themselves.

✦ ✦ ✦

Is Visual Neglect the Same as Vision Loss?

No.

Visual neglect is an attention disorder caused by the brain ignoring one side of the environment.

Vision loss means part of the visual field is physically missing.

✦ ✦ ✦

Should I Still Have My Eyes Tested?

Yes.

Regular eye examinations remain important, even if your vision problems are related to your stroke.
