OcufuseHow to take consistent eye photos at home
Light, distance and angle change how your eyes look in a photo. Six habits that make daily eye photos comparable from one day to the next.
If you photograph your eyes to show a doctor how something changes over time, the photos are only useful if they can be compared. A photo taken by a window at noon and one taken under a ceiling lamp at night can look like two different people. Most of the difference comes from how the photo was taken, not from your eyes.
These habits keep your photos as consistent as a phone camera allows.
1. Use the same light every time
Light is the biggest source of difference between photos. Pick one spot and one time of day and stick to it.
- Face a window with soft daylight, or stand under even indoor light. Avoid light coming from one side, which casts shadows across one eye.
- Turn the flash off. Flash close to the face flattens detail and creates bright reflections in the pupils.
- Never look toward the sun or point a bright light into your eyes.
2. Keep the same distance
Holding the phone closer makes your eyes look bigger and changes the angle of your eyelids. Rest your elbows on a table, or use a phone stand, so the distance stays the same. A distance of about 30 to 40 cm usually keeps both eyes sharp.
3. Keep your head level
Tilting your chin up or down changes how much of the eyelid shows. Look straight into the lens, keep your chin parallel to the floor, and keep the phone at eye height rather than below your face.
4. Take the same set of views
Clinicians often look at the eyes in several positions. Taking the same views each day makes it easier to compare like with like. A simple set is:
- Looking straight ahead
- Looking left
- Looking right
- Looking up
Ocufuse guides you through these four views with on-screen framing, so each photo is set up the same way.
5. Write down what happened
A photo shows how your eyes looked. It doesn't show that you slept four hours, had three coffees or spent the afternoon at a screen. A short note with the time helps your doctor read the photos in context.
6. Keep the photos you didn't like
It's tempting to delete the photos where things look worse. Those are often the most useful ones for your appointment. Keep them, and add a note if something was unusual about the conditions.
