Why your eye photos look different from day to day

If you compare your eye photos side by side, you will probably notice differences. Some are real changes worth mentioning to your doctor. Many come from the photo itself. Knowing the difference keeps you from worrying about the wrong things.

Reasons that come from the camera

• Lighting. Brighter light makes pupils smaller and can make the whites of the eyes look whiter. Warm indoor light makes everything look yellower.
• Distance and lens. Phones use wide lenses. Up close, features nearer the lens look bigger, which can change how your eyelids and eye shape appear.
• Angle. A slight head tilt changes how much eyelid and white of the eye you see.
• Processing. Phones adjust colour, sharpness and brightness automatically, and different phones do it differently.

Everyday reasons that come from you

• Tiredness. Eyelids can look heavier and eyes redder after a short night.
• Time of day. Many people look different in the morning than in the evening.
• Screens and focus. Long periods of close work can leave eyes feeling and looking strained.
• Salt, alcohol and allergies. These can cause puffiness around the eyes.

What this means for your record

One photo on its own rarely tells you much. A series of photos taken the same way, with notes about the day, is far more useful because it shows patterns. That's the idea behind Ocufuse: consistent capture, timed notes, and a timeline you can share.

Ocufuse doesn't measure your photos or judge whether something is normal. Your eye doctor is the right person to interpret what you see.
