TL;DR
If you’ve found that the centre of your sight seems unclear or distorted, you’re not alone, and there are many reasons why this might happen.
Understanding the causes behind blurry central vision is the first step towards seeking the right help and treatment. Let’s dive into the most common causes and provide some guidance on what to do next.
What causes blurry central vision?
Blurry central vision can be a symptom of a variety of conditions, ranging from temporary issues to more serious, long-term eye diseases.
It’s important to know the possible causes so you can get the right diagnosis and treatment early on. Some of the most common causes include:
Age-related macular degeneration (AMD)
As we age, our eyes naturally undergo changes, and one of the most common eye conditions in older adults is age-related macular degeneration (AMD).
This condition affects the macula, the part of the retina responsible for central vision. If you have AMD, you may notice blurry or distorted central vision, making it difficult to focus on details.
There are two types of AMD: dry and wet. Dry AMD is more common and progresses slowly, while wet AMD is rarer but can lead to rapid vision loss.
Regular eye exams can help detect early signs of AMD, and treatment options may include lifestyle changes, medications, or specialised injections.

Diabetic retinopathy
If you have diabetes, you’re at risk for a condition known as diabetic retinopathy. This eye disease occurs when high blood sugar levels damage the blood vessels in the retina, leading to blurry or distorted vision.
The central part of your sight can become unclear if fluid builds up or if blood vessels start to leak into the retina.
Managing your blood sugar levels is key to preventing this condition from worsening, and your eye care provider may suggest laser treatments or surgery to protect your vision.
Macular hole
A macular hole is a small break in the macula, which can cause a sudden or gradual loss of central vision.
While the exact cause isn’t always clear, it’s often linked to age, eye injuries, or conditions like retinal detachment.
If you notice a dark spot or blurriness right in the centre of your sight, you should seek an eye exam as soon as possible.
Surgery is the most common treatment for a macular hole, and early intervention can improve the chances of restoring your vision.
Cataracts
Cataracts are another common cause of blurry vision, particularly as you get older. They develop when the lens of your eye becomes cloudy, making it harder to see clearly.
While cataracts usually affect your entire vision, they can particularly impact your central sight as the condition worsens.
Cataract surgery is a highly effective way to restore clear vision, and your eye care provider can help you determine the right time for this procedure.

Central serous retinopathy (CSR)
Central serous retinopathy is a condition where fluid builds up under the retina, causing blurry or distorted central vision.
It’s often linked to stress or the use of corticosteroids, and while CSR can resolve on its own, it sometimes requires treatment.
If you notice a sudden change in your central vision, particularly if you’ve been under significant stress or taking medications, it’s worth speaking to your eye care provider about CSR.
Optic neuritis
Optic neuritis occurs when the optic nerve, which transmits visual information from your eyes to your brain, becomes inflamed.
This inflammation can cause sudden blurry vision, particularly in the centre of your sight. It’s often linked to autoimmune conditions such as multiple sclerosis.
If you suspect optic neuritis, it’s essential to get medical attention quickly, as early treatment can help prevent further vision loss.
Seeking help and diagnosis
Experiencing blurry central vision is never something to ignore. While some causes might be temporary or easily treated, others may require prompt medical intervention to prevent further vision loss. Here are some steps you can take to address the issue:
- Follow through with treatment: Depending on the cause, your eye care provider may recommend treatments such as surgery, medication, or lifestyle changes. Following their guidance is essential for improving and preserving your vision.
- Book an eye exam: The first step is to get a professional eye examination. Your optician or ophthalmologist will be able to assess your eye health and diagnose any underlying conditions.
- Manage underlying conditions: If you have a pre-existing condition like diabetes or high blood pressure, managing these conditions effectively can help protect your vision.
- Monitor your symptoms: Keep track of any changes in your vision, including how long symptoms last and whether they improve or worsen over time.
Final notes
Blurry central vision can be caused by a variety of conditions, ranging from age-related macular degeneration to more treatable issues like cataracts or central serous retinopathy.
Whatever the cause, it’s important to take blurry vision seriously and seek professional advice. Early diagnosis and treatment can significantly improve your chances of maintaining clear vision.
By staying on top of your eye health and managing any underlying conditions, you can help protect your sight for the long term. Always remember, your vision is worth the extra care and attention.
