Yes, iris recognition is safe for the eyes. Unlike retina or fingerprint scanning, the iris scanner does not require direct contact with the eye or any kind of radiation. It is a completely non-invasive technology which uses a camera to capture an image of the person's iris from a distance of up to 45 cm. The image is then analysed to create a unique biometric profile of the person's iris.
The light source used for iris recognition is filtered for ultra-violet and near infra-red light and its intensity is tuned so that it does not harm the eye. In addition, the software used for the analysis can detect movement, which helps detect and reject images that are too blurry. As a result, iris recognition is a safe and secure method of biometric identification.
Here are some points to consider when using iris recognition:
- Make sure the iris scanner is certified to meet industry and national standards.
- Provide a good light source and ensure that the illumination is appropriate for the scanner being used.
- Ensure that a quality image of the person's iris is captured, while avoiding any glare or reflections caused by surrounding light sources.
