Quick answer: Early macular degeneration symptoms can be subtle. The most common signs are blurred or distorted central vision (straight lines look wavy), trouble reading, needing brighter light, and a growing dark or blank spot in the centre of what you see. If vision changes suddenly, especially distortion or rapid central vision loss, book urgent assessment with an optometrist or eye clinic.
Macular degeneration (often age-related macular degeneration, AMD) affects the macula, the central part of the retina responsible for sharp, straight-ahead vision. In New Zealand, many people notice symptoms gradually, which is why regular eye checks matter. Below we explain the symptoms to watch for, how dry vs wet AMD can feel, and what to do next.

Common macular degeneration symptoms
Symptoms vary by person and by whether changes are early or advanced. Common signs include:
- Blurry central vision: faces or words look soft while side vision may still seem normal.
- Distortion: straight lines on a page, blinds, or door frames look wavy or bent (metamorphopsia).
- Difficulty reading: you may lose your place, skip letters, or struggle with smaller print.
- Needing more light: tasks like reading or cooking feel harder in dim light.
- Less vivid colours or contrast: colours can look duller and edges less clear.
- Dark, grey, or blank spot: a patch in the centre of vision that makes it hard to see details.
Early symptoms can be easy to miss
Early AMD may not cause obvious symptoms, especially if only one eye is affected. The other eye can compensate, so you may not notice changes until they become more pronounced. That is why we suggest periodic eye exams, even if your day-to-day vision feels fine.
Dry vs wet macular degeneration symptoms
Dry AMD symptoms
Dry AMD is more common and often progresses slowly. People usually describe gradual changes such as increasing blur, reduced contrast, and more difficulty reading over time.
Wet AMD symptoms
Wet AMD can develop more quickly. Sudden distortion (wavy lines), a rapid change in central vision, or a new central dark spot can be warning signs. Wet AMD needs prompt assessment.
When symptoms are urgent
Book urgent eye care if you notice:
- new or suddenly worse distortion
- rapid central vision loss in one or both eyes
- a new dark or blank central spot
- flashing lights, a curtain-like shadow, or severe eye pain
Those last symptoms can also relate to other eye conditions, so it is better to get checked quickly.
A simple at-home check: the Amsler grid
An Amsler grid is a square grid of straight lines used to spot distortion. If you use one:
- Wear your reading glasses if you normally use them.
- Cover one eye and look at the centre dot.
- Notice if any lines look wavy, missing, or darker.
- Repeat with the other eye.
If the grid looks different than normal, book an eye exam. The Amsler grid does not replace professional assessment, but it can help you notice changes earlier.
How macular degeneration is diagnosed in NZ
Diagnosis usually involves an eye exam with retinal assessment. Your optometrist or ophthalmologist may use retinal imaging such as OCT (optical coherence tomography) and photos of the retina to look for macular changes. If wet AMD is suspected, they may refer you quickly for specialist care.
Do supplements help with macular degeneration symptoms?
Supplements cannot diagnose, treat, or cure macular degeneration. However, certain nutrients are commonly discussed in the context of eye health and healthy ageing, including lutein and zeaxanthin (carotenoids), zinc, and antioxidants. Some evidence-based formulations (often discussed as AREDS2-style nutrient combinations) are used under professional guidance for specific people.
If you are exploring options, start with products that are designed for vision support and fit your routine. You can browse our eye support range here: Top vision support. If you are specifically looking for lutein options, see: Lutein collection.
Prefer a simple daily capsule? Many customers start with: XTR Vision with Lutein. If you have existing eye conditions or you take medicines (for example blood thinners), we recommend checking with your pharmacist or GP before adding supplements.
What else can support your eye health
- Regular eye checks: especially if you are over 50 or have a family history of AMD.
- Do not smoke: smoking is a major modifiable risk factor for AMD.
- Protect eyes from UV: wear sunglasses with UV protection outdoors.
- Eat for eye health: leafy greens, colourful veg, fish, and adequate protein are practical foundations.
- Manage overall health: blood pressure and cardiovascular health matter for healthy ageing.
FAQs
What are the first symptoms of macular degeneration?
Early signs are often blurred central vision, trouble reading, and distortion where straight lines look wavy. Some people also notice they need brighter light or see a faint grey patch in the centre of vision.
What does macular degeneration distortion look like?
Distortion often shows up as straight edges appearing bent or wavy, such as lines of text, window frames, or tiles. An Amsler grid can make this easier to notice.
How do dry and wet macular degeneration symptoms differ?
Dry AMD symptoms usually change slowly over months or years. Wet AMD symptoms can appear more suddenly, with rapid distortion or a new dark central spot, and need prompt eye assessment.
When should I see an optometrist for macular degeneration symptoms?
Book an eye exam if you notice new blur, distortion, or a central dark spot. Seek urgent assessment if symptoms come on suddenly or worsen quickly.
Can macular degeneration cause blindness?
Macular degeneration can seriously affect central vision, which is needed for reading and recognising faces. Most people keep some side (peripheral) vision, but the impact can still be significant, so early detection and support matter.
Can supplements improve macular degeneration symptoms?
Supplements are not a cure and will not replace eye care. Some nutrient combinations are used under professional guidance for specific people, so it is best to discuss supplements with your optometrist, GP, or pharmacist based on your situation.
