X-Chrome Contact Lenses

X-Chrome contact lens is a red contact lens worn in one eye and is used to overcome red-green colour vision deficiencies. As the red contact lens is only carried in one eye, the patient can compare different contrasts between the two eyes. The lens is named the “X-Chrome” lens because the gene that causes the problem is carried on the X chromosome.

These lenses are traditionally manufactured in a soft contact lens and at Ezekiel Eyes there are certain tests we use to evaluate if the X-Chrome lens is suitable for the patient.

Contact lenses are a good option for many individuals such as a natural field of view patient with active lifestyle and compared to spectacles generally offer better sight. The initial examination for contact lenses requires more time and follow up visits at Ezekiel Eyes are designed to maintain eye health.

For a patient to be a successful contact lens wearer proper cleaning and storage of the contact lenses, follow the wear schedule given by your Optometrist and have regular follow-up care as directed by your optometrist.

Lenses for colour deficiency
Colour deficiency is a condition characterized by colour confusion and the inability to discriminate certain colours. Approximately 8% of males and 0.5% of females in North America have some form of colour deficiency.

Their altered colour perception is due to a malfunction in the retina of the trichromatic-three-receptor colour (red, green, and blue) vision system.

In nearly all cases a more appropriate term to use would be colour deficiency because the anomaly does not produce a total absence of colour perception, but rather, the inability to discriminate between specific chromatic (colour) stimuli.

For many years, the X-Chrome lens has been used to improve colour discrimination in affected individuals. This lens is a red contact lens that is worn in the non-dominant eye. Its principle is to create what is referred to as retinal rivalry, which results in the brain being able to better distinguish between shades of colour.

Who needs colour vision enhancement lenses?
If you suffer from inherited or acquired colour deficiency or colour deficiency, X-chrome lenses can help you. The lenses may help individuals with defective colour vision in occupational fields as diverse as law enforcement, the electronic and computer industries, graphic and fine arts, textiles, transportation and scientific fields.

For children and adults, the lenses will eliminate many of the academic challenges that arise when colour deficient students are faced with colour-coded learning and teaching materials. In addition, these lenses are ideal for colourblind people who want to improve the quality of many recreational activities.

Who is suitable for X-Chrome or ChromeGen lenses?
Ezekiel Eyes is one of only a handful of practices in Australia to provide these colour vision enhancement systems to their patients. As in all areas of our practice, we embrace cutting edge technology to provide our patients with the best care possible.
