In this detailed guide, we will explore the reasons behind the appearance of red eyes in iPhone photos and provide a step-by-step guide on how to effectively fix this issue. From understanding the science behind red eyes to utilizing built-in tools, let's embark on a journey to enhance the quality of your iPhone photography.

Why Is There Red Eye on iPhone?

1. Reflection of Light:

The appearance of red eyes in photos is primarily due to the reflection of light off the blood vessels in the retina when the camera flash illuminates the eyes.

   - Example Scenario: Using the iPhone flash in low-light conditions often intensifies the reflection, resulting in red eyes.

2. Proximity of Flash to Lens:

The iPhone's compact design places the flash close to the lens, increasing the likelihood of direct light reflection from the retina.

   - Example Scenario: Capturing photos in dimly lit environments with the flash enabled can lead to red eyes.

3. Pupil Dilation:

In low-light conditions, the pupils dilate to allow more light to enter the eyes, making the red reflection more pronounced.

   - Example Scenario: Shooting in dark environments without adjusting the flash settings can accentuate red eyes.

4. Photography Settings:

Incorrect camera settings, such as using the default flash mode, may contribute to red eye issues.

   - Example Scenario: Auto flash mode activating inappropriately during portrait shots can result in red eyes.

5. Photography Distance:

The distance between the subject and the camera influences the intensity of red eye reflection.

   - Example Scenario: Capturing close-up shots with the flash can lead to more pronounced red eyes.

How to Fix Red Eye on iPhone

1. Use the Built-in Red Eye Correction Tool:

   - Step 1: Open the Photos app and select the photo with red eyes.

   - Step 2: Tap "Edit" at the top right.

   - Step 3: Tap the eye icon at the top left.

   - Step 4: Position the crosshair over each red eye and tap "Done."

The iPhone's Photos app provides a built-in tool specifically designed to detect and correct red eyes in photos.

 2. Adjust Camera Settings: 

   - Step 1: Open the Camera app on your iPhone.

   - Step 2: Tap the flash icon and choose "Off" or "Auto" to control the flash manually.

   - Step 3: Ensure the "Red Eye" reduction setting is enabled in the camera settings.

Manually adjusting flash settings and enabling red-eye reduction can prevent or minimize red eyes during photo capture.

3. Capture Photos Without Flash: 

   - Step 1: Turn off the flash by tapping the flash icon in the Camera app.

   - Step 2: Capture photos in well-lit environments to reduce the need for flash.

Avoiding the use of flash in well-lit conditions can eliminate the chances of red eyes appearing in photos.

4. Increase Photography Distance: 

   - Step 1: Increase the distance between the camera and the subject when capturing photos.

   - Step 2: Use the zoom feature to maintain distance while capturing close-up shots.

Increasing the photography distance minimizes the intensity of the flash reflection, reducing the likelihood of red eyes.

5. Edit Photos with Third-Party Apps: 

   - Step 1: Use third-party photo editing apps with red-eye removal features.

   - Step 2: Select the red eyes and apply the correction within the editing app.

Explore third-party apps with advanced editing features to manually correct red eyes in photos.

6. Adjust Pupil Dilation: 

   - Step 1: Capture photos in well-lit conditions to reduce pupil dilation.

   - Step 2: Adjust the flash settings to prevent unnecessary dilation in low-light scenarios.

Controlling the lighting conditions and flash settings can mitigate pupil dilation, minimizing red eyes in photos.

7. Capture Photos in Burst Mode: 

   - Step 1: Hold down the capture button to activate Burst mode.

   - Step 2: Select the photo with the least pronounced red eyes from the burst.

Burst mode captures a series of photos in quick succession, providing options to choose the frame with the least red-eye effect.

Additional Tips and Considerations

1. Use External Lighting: 

When possible, utilize external lighting sources instead of the built-in flash to capture well-lit and natural-looking photos.

2. Experiment with Portrait Mode: 

Portrait mode on newer iPhone models often utilizes advanced depth-sensing technology, minimizing the impact of red eyes in photos.

3. Be Mindful of Reflections: 

Avoid capturing photos where the subject is directly facing a reflective surface, as it may intensify red-eye reflections.

4. Educate Subjects on Posing: 

Inform subjects to avoid looking directly into the camera flash to reduce the chances of red eyes.


Capturing memorable moments on your iPhone should be a joyous experience without the distraction of red eyes in photos. By understanding the factors contributing to red eyes and following this step-by-step guide, you can enhance the quality of your iPhone photography. Embrace the creative possibilities, experiment with settings, and cherish moments with stunning, red-eye-free photos.
