Have you ever taken the perfect family photo only to find everyone has glowing red eyes? This often happens when the camera flash bounces off the back of the eye, especially in dim lighting. People with lighter skin and blue eyes are more prone to this due to lower melanin levels. Many cameras include red-eye reduction settings, but the issue can still happen. Good news is removing the red eye effect in photos is now easier than ever.
Whether you’re using Photoshop, your iPhone’s built-in tools or free online editors, there are simple ways to fix it. This article will show you the fastest and easiest ways to remove red eye from photos, whether you’re using a desktop, mobile or online editor. So your memories stay flawless and natural, let’s fix those eyes and bring your pictures back to life!

Part 1: What Causes Red Eyes in Photos?
Red eye in photos occurs mainly because of the eye’s anatomy and how it interacts with the camera flash. Understanding this phenomenon requires a closer look at how our eyes work.
When a camera flash goes off in dim lighting conditions, light passes through the cornea and pupil before reaching the retina at the back of the eye. The retina functions like camera film, capturing light and converting it to electronic pulses that travel through the optic nerve to create visual images in the brain.
But not all light is absorbed by the retina. Some light reflects back to the camera lens, illuminating the blood-rich choroid layer behind the retina. This layer feeds the retina and provides it with a natural red color, so the eyes appear red when this reflection is captured on film.
Several factors increase the likelihood of red-eye effect:
- Pupil dilation: In dark settings, the pupils get larger to allow more light into the eyes. When a flash goes off suddenly, the pupils can’t constrict fast enough to prevent the light from reflecting off the retina.
- Direct gaze: Looking directly at the camera lens creates a perfect angle for light to reflect straight back to the camera.
- Eye anatomy: People with larger pupils naturally experience more pronounced red-eye effect regardless of lighting conditions.
- Melanin levels: People with lighter colored eyes (blue or green) have less melanin and are more prone to red-eye in photos.
- Flash proximity: The closer the flash is to the camera lens, especially in cameras with built-in flash, the more likely red eye is to occur.

Part 4: How to Fix Red Eye in Lightroom
Adobe Lightroom is a simple way to fix red eye in photos without switching to more complex editing software. It’s part of Adobe’s Creative Suite and is designed to be powerful yet easy to use. Lightroom Classic has more precision with the Adjustment Brush for tougher cases.
One advantage of using Lightroom for red eye correction is it’s non-destructive. Your original image remains untouched, so you can adjust or remove corrections anytime. Plus, once you’ve perfected your correction technique, you can save it as a preset to apply to other photos with similar issues.
Follow these steps to remove red-eye from your photos online using Lightroom:
Step 1
Import the image you want to edit into Lightroom. Go to the Develop module from the top panel.
Step 2
Click the Red Eye Correction tool in the toolbar, usually located on the right side panel. You can also press Ctrl + Plus (Windows) or Command + Plus (Mac) to zoom in for better accuracy.
Step 3
By default, the tool is set to Red Eye, for human subjects. For pets, switch to the Pet Eye tab. Click the center of one red pupil to correct it, then do the same for the other eye.
Step 4
Click on a circled area to select it, then adjust the result using the Pupil Size and Darken sliders.
Step 5
If the subject isn’t facing the camera directly, use the Hand Tool to move the circle. Then, adjust the pupil size and darkness again for better accuracy.
Step 6
Zoom out to view the entire image and review the final result. If needed, go back and adjust again.
With Lightroom, you can remove red eye Photoshop style, without the full Photoshop suite. The red eye removal Lightroom process is fast, and you can easily undo or fine-tune edits without changing the original image.

How to Stop Red Eye When Taking Photos
Prevention is always better than correction when dealing with the notorious red eye effect in photos. Instead of spending time editing photos after they're taken, photographers can implement several strategies to minimize or completely avoid this issue in the first place.
Here are six effective techniques to prevent red eye when taking photos:
Use the red eye reduction feature on your camera.
Most modern digital cameras and smartphones have this setting, which emits a pre-flash or series of small flashes before the main flash. This makes the pupils contract before the photo is taken, so less light reflects back.
Increase the ambient light in the room.
The main cause of red eye is dilated pupils in low light. By brightening the overall environment, you naturally constrict the pupils, reducing the likelihood of red eye.
Position your light source away from the camera.
When using external flash units, position them at an angle rather than directly above or beside the camera. This changes the angle of reflection so the light doesn’t bounce straight back into the lens.
Ask your subject to look slightly away from the lens.
Direct eye contact with the camera creates the perfect angle for light to reflect back from the retina. Having your subject look slightly to one side eliminates this direct path.
Let your subject’s eyes adjust to the light before shooting.
If possible, have your subject spend a few minutes in well lit areas before taking photos. This natural adjustment period allows the pupils to constrict.
Use natural or off-camera light whenever possible.
Natural light photography never produces red eye. Bounce flash off ceilings or walls for indoor shots rather than pointing it directly at your subject.
Conclusion
Red eye in photos may seem like a minor issue, but it can really impact the overall quality and impression of your images. Whether you’re a pro photographer or just capturing everyday moments, knowing how to remove red eyes efficiently is crucial. There are plenty of options from powerful desktop tools like Photoshop red eye tool and Lightroom red eye removal, to online solutions like Pixlr AI, and even apps to remove red eye in pictures like UniConverter’s AI batch tool. And don’t forget, prevention is better than correction. Follow simple camera setup tips to avoid the red eye effect before it even starts. Now you’re ready to edit out red eye with confidence, on PC, mobile or online.

FAQs
-
1. Can red eye removal tools fix animal eye shine?
Most standard red eye removal tools are designed for human eyes and struggle with animal eye shine. Animal eyes reflect light differently, typically producing a green or yellow glow instead of red. Specialized animal eye shine correction features or manual editing techniques work better for pet photos. -
2. Will red eye correction work on old scanned photos?
Yes, red eye correction tools work on digitized old photographs. Once scanned, these images can be processed using any of the methods mentioned above. But you may need to adjust contrast and brightness first to improve the tool’s ability to detect the red areas accurately. -
3. Why do some people get red eye more frequently than others?
Eye color and pupil size mainly determine susceptibility to red eye effect. People with lighter colored eyes (blue, green, gray) get more noticeable red eye because they have less melanin to absorb the flash. Larger pupils naturally allow more light to enter and reflect back, increasing the chance of red eye in photos. -
4. Can smartphone cameras prevent red eye?
Modern smartphones have various technologies to reduce red eye, including separate flash positioning, pre-flash functions and computational photography. But in low light, even the best camera still needs some help from a get rid of red eye app. -
5. Is there a way to remove red eye from photo of multiple people in a group photo at once?
Batch-processing tools like Wondershare UniConverter can correct an entire image at once, while other programs require treating each eye individually. For group photos with multiple subjects, dedicated red eye removal software saves a lot of time compared to manual editing.
