Flash photos often turn pupils red, but a dedicated red-eye tool in Lightroom or Apple Photos removes the effect in seconds.
Knowing how to edit red eyes out of pictures saves otherwise great portraits from the trash bin. Red eye happens when a camera flash reflects off the retina at the back of the eye. Nearly every major photo editor—from Adobe Lightroom to Apple Photos—includes a one-click fix. Here are the best methods for Windows, Mac, and web browsers, plus a manual fallback that works on any software.
What Is The Fastest Way To Fix Red Eyes?
The fastest route is an auto red-eye tool. You click directly on the red pupil, and the software detects the surrounding area and corrects the color. Most editors also let you fine-tune the Pupil Size and Darken settings if the auto detection misses the mark. The whole process takes about ten seconds per photo.
Removing Red Eye in Adobe Lightroom
Adobe Lightroom offers the most control and consistency. Open the photo in the Develop module and follow these steps:
- Click the Red Eye icon (it looks like an eye).
- Click and drag from the center of the red pupil outwards. Lightroom auto-detects the affected area.
- Adjust the Pupil Size and Darken sliders if the correction looks too small or too light.
- Repeat for each eye.
Lightroom also has an Auto Correct button that detects and fixes all red eyes in a single click. The red glow vanishes, leaving a natural dark pupil. Adobe’s official red-eye removal guide documents the same workflow.
How to Edit Red Eyes Out of Pictures on a Mac
Apple Photos on Mac includes a dedicated red-eye tool that is completely free and ready to use. Open the photo, click Edit, then Adjust, and scroll down to Red-Eye. Click the Auto button to correct every red pupil at once. If you need to fix one manually, drag the Size slider and click the red part of each pupil individually. Apple’s support document confirms this works on all recent versions of macOS.
How to Remove Red Eyes on a Windows PC
Windows users have two solid routes. PaintShop Pro handles both human and animal red eye. Open the photo, go to Adjust > Red Eye Removal, and select the Auto Human Eye or Auto Animal Eye method. Click the red area and the tool corrects it.
Important gate: The new Microsoft Photos app does not include red-eye removal. Microsoft’s own answer on this topic points users to install Photos Legacy. Open the new Photos app, go to Settings, and select Get Photos (Legacy) to regain the old red-eye feature alongside other classic tools.
Fixing Red Eyes Online with Picsart
If you do not want to install software, Picsart’s web-based red-eye remover works in a browser. Upload your image, tap the Red Eye Remover tool, and click each pupil. The checkmark saves the result. It is a fast option for users on a shared computer or making a quick fix on a Chromebook.
Manual Red Eye Correction (The Universal Fallback)
When auto tools fail—common with eyes that are tightly closed, oddly shaped, or hit by an LED flash—a manual layer method works on any editor. In Acorn 8, Photoshop, or similar software:
- Create a new layer above the image.
- Paint a small black dot over each red pupil with a soft brush.
- Set the layer’s opacity to around 50%.
- Apply a Gaussian Blur with a radius of 1 to 3 to soften the edges.
The result mimics a natural iris tone. Use a light touch—an overly dark, sharp pupil looks unnatural from across the room.
Why Red Eyes Happen and How to Prevent Them
Prevention is even faster than correction. Red eye occurs because the flash reflects off the blood-rich retina straight back into the lens. Most cameras offer a Red-Eye Reduction flash mode that fires a pre-flash to shrink the pupils before the main flash. Bouncing the flash off a ceiling or wall also eliminates the straight reflection. Set these preferences before your next indoor portrait session.

How to Edit Red Eyes Out of Pictures: The Final Workflow
The best method is the one you use. Start with the auto tool inside your current photo app—Apple Photos and PaintShop Pro handle most cases in a single click. If the auto tool misses, manually paint a dark layer at reduced opacity and blur it. Keep your camera’s red-eye reduction flash turned on for future events, and you will spend far less time fixing glares later.
