Overview
When your vision goes blurry it helps to know who to see. There are three types of eye care professionals in Singapore. Each does a different job. An optician fits glasses. An optometrist tests your sight and screens for problems. An eye doctor (called an ophthalmologist) is a medical doctor. They diagnose and treat eye disease and do eye surgery. For serious problems with the retina, cataracts or eye inflammation, seeing an eye doctor early helps protect your sight.

Introduction
Imagine you suddenly notice that signs look distorted or a blur clouds your vision. Many people assume they just need stronger glasses. But sudden vision changes can come from a deeper problem inside the eye. This may involve the lens, the retina or the macula (the central part of the retina). When new glasses do not fix the problem it is important to see a qualified eye doctor.
Singapore has very high rates of short sightedness (myopia). It also has an ageing population. This means more people are getting serious eye conditions such as macular degeneration, diabetic eye disease and retinal detachment. This guide explains who to see, when to get help quickly and how eye clinics treat these conditions.
Who Does What: Optician, Optometrist and Eye Doctor
It helps to understand the difference between the three.
When Blurry Vision Is an Emergency
Some vision changes happen slowly. Others need urgent care. Watch out for these warning signs:
- Sudden floaters or flashes of light - This can mean a tear in the retina or an early retinal detachment. Left untreated it can cause permanent sight loss within days.
- Straight lines looking wavy or bent - This is a classic sign of a problem with the macula. It may be wet macular degeneration or a macular hole.
- Blurry vision that comes and goes in diabetics - Blood vessels in the retina leak fluid. This can be a sign of diabetic eye disease.
Regular checks with an eye doctor help catch these changes early.
Common Conditions an Eye Doctor Treats
Eye doctors treat far more than blurry vision. Common conditions include:
- Cataracts - The eye's lens slowly turns cloudy with age. Surgery removes the cloudy lens. It is replaced with a clear artificial one (called an intraocular lens or IOL) chosen to suit your needs.
- Macular degeneration and blocked retinal veins - These often need injections of medicine into the eye. Examples include Eylea, Vabysmo or Ozurdex. They reduce swelling and calm leaky blood vessels.
- Eye inflammation (uveitis) - This needs special care. It is often linked to a problem with the body's immune system.
What Happens at an Eye Doctor Visit
Your first visit follows a clear step by step process. It starts with a chat about your symptoms and health history. Next come simple tests. These include a sight test and an eye pressure check to screen for glaucoma. To look deep inside the eye the doctor uses drops to widen the pupils. This lets them see the retina, macula and optic nerve clearly. Special scans (called OCT) and detailed eye photos give a close up view. They show any fluid or damage. The drops make your sight blurry and light sensitive for a few hours. So it is best not to drive straight after your visit. Bring someone with you if you can.
Choosing the Right Eye Doctor
When choosing a specialist it helps to check their training and experience. Look for an eye doctor who is specially trained (fellowship trained) in the area that matches your problem. This may be retinal disease, eye inflammation or cataract surgery. Many years of experience and a strong track record offer peace of mind. It also helps to think about how easy the clinic is to reach and how billing works. A clinic that works with major Integrated Shield Plans and company insurance makes it easier to manage the cost of treatments such as cataract surgery or regular eye injections.
Your Path to Clearer Vision
Protecting your sight starts with seeing the right person at the right time. Opticians and optometrists are helpful for everyday glasses and checks. But lasting blur, sudden floaters or signs of retinal disease need a medical eye doctor. Catching problems early is the best way to protect your sight.

Frequently Asked Questions
What is the difference between an optometrist and an eye doctor?
An optometrist mainly tests your sight, prescribes glasses and does eye health checks and screening. In hospitals they may also help monitor patients with stable conditions under an eye doctor's guidance. An eye doctor (ophthalmologist) is a medical specialist. They can run detailed tests, prescribe medicines, do laser treatment and perform surgery such as cataract removal or retinal repair.
How does an eye doctor check for macular degeneration?
The doctor uses a detailed scan (called OCT) to look at the layers of the retina. They also examine the macula using eye drops and special lenses. This helps them spot leaky blood vessels, fluid or thinning of the tissue.
How often should I have my eyes checked?
If you are over 50, very short sighted or have conditions like diabetes or high blood pressure, a yearly eye check is recommended. Regular checks help find silent problems such as diabetic eye disease or glaucoma before they affect your sight.
