iRo Lenses
Digital Colour Vision Test

The traditional Colour Vision test with a series of dots and numbers was created over 150 years ago. Now the digital age is upon us we have developed the iRo method of assessing Colour Vision Sensitivity

Here’s how it works.

We use three distinct shapes. A Diamond, Cross and a Circle.

They can appear at random positions on the page.

Now for the Diagnostic Test.

Are you a Deutan or Protan ?? And is your Sensitivity to colours Mild, Medium or Strong?

Once this is determined then you can find the best iRo lens that will improve your Colour Vision Sensitivity and you will see the improvement immediately.

After many years of research the remarkable iRo lenses will improve your Colour Perception and you will see new more Vibrant Colours like never before.

There will be one of the 6 iRo lenses that allow you to successfully pass the Ishihara test or any of the Colour Vision screening tests.

The iRo App has three distinct functions

1. Colourblind Test. Do you have a decreased sensitivity to Colours?

2. What is your specific level of Colour Vision Sensitivity. Protan or Deutan? High, Medium or Low? 

3. Which iRo lens individually improves your Colour Vision Perception to the highest possible level.

Please read the instructions carefully.

Optometrist Ian Rosser and his team have spent over 15 years working with and researching colourblindness. Because there are different types and several various degrees of Colour Vision Sensitivity they have developed 6 distinct filters which can be tailor made to individually help 99% those who have a decreased Colour Vision Sensitivity.

Colourblind testing has not changed in over 150 years. If you have decreased Sensitivity to Colours you will be familiar with the old round dots with the numbers.

The iRo App is designed for the 21st Century. We live in a digital age. We've taken a whole new approach towards colour vision and designed a test that relates to the world we live in.

This App will enable you to visualize what it would be like to look through each of the 6 iRo lenses and enable you to purchase the lens that gives you the most comfortable increase in Colour Vision Perception.

Should you have any further questions Ian and his staff are available via email from the iRo Lens web site.

We have already helped thousands of people around the world and we're only too happy to answer any of your questions.

The power to see New more Vibrant Colours is now in your hands.
