Colour vision deficiency (commonly called “colour blindness”) changes how certain colours appear, most often reds and greens, sometimes blues and yellows, and in rare cases almost all colours. It can affect reading charts at school, choosing clothes, reading signs or data visualisations at work, and even safety-related tasks.
Common types include:
- Red–green (most common)
- Blue–yellow (less common)
How colour blind glasses work
- The science in short: Our colour blind aids use specially tinted lenses that adjust the wavelengths of light entering the eyes, enhancing colour perception and helping certain hues stand out more clearly. By filtering specific wavelengths, these lenses increase contrast between commonly confused colours, making them easier to distinguish in everyday situations.
- What they can do: Improve colour separation and make some hues look more vivid, which can help with day-to-day tasks and enjoyment.
- What they can’t do: They don’t cure colour blindness or change genetics, and results vary by person and deficiency type. Some environments (e.g., low light) may reduce the benefit. A proper consultation helps set the right expectations.
Colour blind test in Singapore: how to know if you need glasses
A structured test confirms your type and severity, which guides the choice of glasses or aids. Here are the different types of tests:
Ishihara plates (most common and reliable red–green test):
A set of number or pathway “dot” plates that reveal how you see reds and greens. It’s fast, child-friendly, and great for first-line screening, but it doesn’t measure severity precisely or pick up every type.
Digital screening tools (convenient checks):
App- or tablet-based tests that mimic standard charts and add quick reaction tasks. Useful for remote or on-the-spot checks, though results can vary with screen brightness and colour accuracy.

Benefits of using colour blind glasses
Colour-enhancing glasses won’t change your genetics, but for many people, they make colours easier to tell apart and everyday tasks feel less frustrating. Here’s how they can help:
- Clearer colour distinction in daily life
Labels, charts, maps and classroom materials become easier to read because similar shades separate more clearly. This can save time at work or school and reduce mistakes when colours carry meaning (e.g., graphs, wiring, signage). - More confidence and comfort with colour tasks
When reds, greens or blues are less confusing, you spend less energy second-guessing. That can make activities like choosing clothes, collaborating on design work, or reading data visualisations feel more natural and less tiring. - A richer visual experience on screens and outdoors
Filters can boost contrast between tricky hues, so sunsets, greenery, sporting kits and digital interfaces appear more distinct. Many users find this makes leisure time and device use more enjoyable.
Results vary by person and lighting. That’s why we offer in-store trials, so you can experience the difference first-hand before deciding.
