Smartphones are equipped with robust cameras that can capture exceptional photographs. By employing the right techniques, you can utilize your phone to capture high-quality images of your eyes.

General Tips

  1. The rear-facing (back) camera captures higher-quality photos compared to the front-facing (“selfie”) camera. To capture your eye in selfie mode using front camera is nearly impossible and frustrating due to level of camera and eye. You need to look down to view quality of images or snap lots of looking straight ‘guess’ images and pick the best. Iris biometrics is the only solution at this time for taking self eye images.
  2. Centering and focusing the image are much simpler when photographing someone else. We highly recommend enlisting the assistance of a friend or family member!
  3. If finding an assistant proves challenging, you can attempt using your rear-facing camera while standing in front of a mirror. This allows you to view your phone screen in the mirror, facilitating adjustments for focus and centering.

General Instructions:

  1. Ensure you’re in a well-lit room with the lights turned on.
  2. Activate the flash and if available in phone camera setting, although not required, set the default to zoom to 2-3x (2.5x is optimal).
  3. Hold your phone in vertical position.
  4. Position the phone’s rear-facing camera as close to the eye as feasible while maintaining sharp focus, typically around 3-4 inches away. It’s crucial to ensure the image remains crisp and clear.
  5. The entire eye should be visible and centered in the photo, with eyelids opened as wide as possible and no shadows obscuring the eye or pupil.
  6. Steadily hold the phone while capturing the photo. Use a tripod or brace your elbows firmly against your body to stabilize the phone.
  7. Encourage the subject to keep their eye still.
  8. The cropping box displayed in eye capture screen is required to produce 4:3 ratio images. You must crop image before saving to gallery or sending for assessment.
  9. Try not to take photo’s with flash light source obscuring the pupillary borders, this may lead to false positives.
  10. Try to have your eye facing a strong, but not direct, light source.
  11. Avoid taking the photo in direct sunlight.
  12. Repeat the process to capture photos of the other eye. Each eye should be photographed separately. Start with right eye first.
