Blurred central vision

Blurred central vision?
Central vision is what you use to read, recognise faces and see detail. When the middle of your vision goes blurred, wavy or blank — while the sides stay clear — the macula, the small central part of the retina, is often involved.
This page explains what blurred central vision can mean, what usually causes it, and how quickly you need to be seen in Singapore. It is general information only, not a diagnosis. Only an examination can tell which cause it is.
WHAT DOES BLURRED CENTRAL VISION FEEL LIKE?
Reading becomes harder, even with glasses
Faces look blurred in the middle, while the outline stays clear
Straight lines — door frames, tiles, lines of text — look wavy, bent or crinkled
A blurred, dim or missing patch appears in the middle of your vision
Colours look faded, or print looks smaller or distorted in one eye
It can affect one eye or both. It can come on gradually over weeks, or suddenly over hours. Sudden change matters more — see "When to act" below.

WHAT COULD CAUSE IT?
A blurred patch in the centre can be due to a few different problems with the macula. They can feel similar at first, which is why an examination — usually with a macular OCT scan — matters.
Macular degeneration — blurred central vision, or trouble reading as you get older
Age-related macular degeneration affects the macula. Central vision becomes blurred or distorted, while side vision usually stays. It is one of the most common causes of central vision loss in older adults. Early detection matters: some forms can be slowed or treated, and regular monitoring catches change sooner.
Macular hole — a blurred or missing patch in the middle of your vision
A macular hole is a small break in the centre of the retina. Reading and fine detail become difficult, and straight lines may look bent. It is found with a detailed retinal scan and, when it affects vision, is usually treated with surgery inside the eye.
Epiretinal membrane — straight lines looking wavy or crinkled
A thin layer of scar-like tissue forms on the surface of the retina and pulls on it slightly, distorting what you see. Many people notice it first when door frames, tiles or lines of text look wavy. Mild cases are monitored; if distortion interferes with reading or daily life, surgery may be discussed.
Central serous retinopathy — a dim or blurred patch in one eye
Fluid collects under the retina, often in one eye, making central vision dim, blurred or slightly smaller-looking. It is more common in younger and middle-aged adults, and stress is often a factor. Many cases settle on their own, but it needs monitoring, because repeated episodes can affect vision.

Diabetic retinopathy — living with diabetes?
Diabetes can damage the small blood vessels in the retina, often with no symptoms at first. Swelling of the macula can blur central vision. That is why regular retinal checks matter even when your vision seems fine. If you have diabetes, ask how often your retina should be checked.
WHAT HAPPENS AT AN APPOINTMENT?
At The EyeClinic, Dr Cheryl Lee will check your vision, examine the front and back of the eye, and use a macular OCT scan and a retinal scan — a detailed scan of the retina and macula. Your pupils are often dilated, so the retina can be seen properly. Dilation makes vision blurry and light-sensitive for a few hours and do not drive yourself home.
You will leave knowing what was found, what it means, and what happens next — whether that is monitoring, drops, injections, laser, or surgery.
FAQs
1. Why do straight lines look wavy?
Straight lines looking wavy or bent often point to a problem with the macula, the central retina — for example an epiretinal membrane, macular degeneration, or a macular hole. Book an assessment within days, and the same day if it started suddenly.
2. Is blurred central vision an emergency?
Not always — but it is urgent if it started suddenly in one eye. Sudden blurred central vision should be checked the same day. Gradual blurring should still be checked within days, not left for months.
3. Can blurred central vision be fixed with new glasses?
Usually not, if the macula is involved. New glasses help refractive problems, but they do not fix a macular hole, swelling, or degeneration. A macular examination is needed to tell the difference.
4. I have diabetes but my vision is fine — do I still need an eye check?
Yes. Diabetic retinopathy can damage the retina with no symptoms at first. Regular annual retinal checks are how it is caught early, when treatment works best.
5. What is an OCT scan?
An OCT scan is a painless, detailed scan of the retina that shows the macula in cross-section. It helps your doctor see fluid, swelling, a hole, or a membrane that cannot be seen clearly by looking alone.
