Color Blindness (Rabun Warna 色盲)
We have different solutions for patients who are color blind. There are 5 different types of color blindness and each requires a unique system called the Colorist System for color blind solution, this provides a whole new world of color. These Colorist Systems can be worn as either contact lenses or spectacles. Colorist Systems can include Chromagen lenses, ColorMAX, Colorlite, Colorview, etc.

Color deficiency (Rabun Warna 色弱), also known as color blindness (Rabun Warna 色盲), is a condition where some people have a deficiency in one or more of the primary colors (red, green, or blue) recognized through the retina (back of the eye). Color blindness (Rabun Warna 色盲) or color deficiency (Rabun Warna 色弱) affects over 3 million people in some form or another. Approximately 10% of males are color deficient but only 0.6-0.8% of females are color deficient. It is caused by a deficiency of certain chemicals in the retina of the eye.

What is Color Blindness Or Deficiency (Rabun Warna, 色盲)? What Help Could We Offer?
Defective color vision can range from near-normal ability to distinguish colors where typically the chemical for seeing red or green is slightly altered to a high degree of confusion where the chemical balance is considerably altered. In the most severe color blind cases, deeper colors, as well as pale colors, will be confused by the eye, particularly if the lighting is poor.
Our practice carries different types of product solutions for color blind(Rabun Warna 色盲) patients, e.g. Chromagen, ColorMAX, Colorlite, Colorview etc.
These unique systems (called Colorist Systems) can be worn as either contact lenses or color blind glasses. For people suffering from color deficiency (Buta Warna, 色弱) or "color blindness" , special filters work by changing the wavelength of each color going into one or both eyes, which enhances color deficiencies, this improvement can be dramatic and life changing. Even colors that are normally correctly identified often seem brighter, richer and more vivid while other shades and colors may be perceived for the first time.
Color deficiencies can be grouped into the following categories:
- Deutrans (lack in green receptors)
- Protans (lack in red receptors)
- Tritans (lack in blue receptors)
- Monochromatics (sees only 1 pigment)
- Achromatics (has no functioning cones)
These Special System Lenses Can Realistically Be Expected To Achieve The Following:
The aim of this system for color vision is to improve color perception in real-world situations; however it is also very likely that scores on color vision tests will dramatically improve. Color vision, and color naming in particular, will normally improve rapidly when using special color blind glasses or lenses within the first couple of months.
With some patients with color blindness (Rabun Warna, 色盲), however, the results are more immediate and they are able to pass tests after just a few hours of using these color blind glasses/lenses.
- Improve general color perception
- Make colors brighter and cleaner
- Allow shades of color, previously unseen, to be observed
- Improve the ability to name colors correctly(especially when assistance is provided in this area, e.g. by relatives or friends).
- Improved color vision may also lead to improved safety, for example through earlier identification of hazard warning lights and brake lights on the roads. Until recently there has been no effective treatment for color deficiency and sufferers have had to make adjustments in the real world themselves(for example, distinguishing traffic lights by their position on the post rather than by the different colors).

Color Blind Tests:
Color Vision Examination
Apart from the color vision screening, we also offer other in-depth color blind test in order to classify the nature and severity of particular color deficiency (Buta Warna, 色弱).
Farnsworth D-15 Test
This alternate color blind test is to differentiate various types of moderate red-green or blue-yellow color vision defects.
L'Anthony Desaturated Test
Tests for mild color blindness to acquire color vision problems caused by ocular pathology.
