Key Takeaways

  • Red-eye is caused by the flash light bouncing back off the eye, mostly in low light.
  • A red eye remover built into your phone or apps takes about 10 seconds to fix red eye.
  • For the best control. Photoshop gives the cleanest results on stubborn shots.
  • To fix red-eye in pets, manually selecting colour works; the glow in their images isn’t red; it appears green, yellow, or blue.
  • Prevention is simple: don’t make eye contact with the camera, or use proper lighting while shooting.
You take a great photo, and then everyone’s eyes come out red. It’s almost always the flash, especially in a dim room. When the flash light hits the eyes, it causes the pupils to widen, which leads to the redness. A good red eye remover on your phone, in an app, or in Photoshop can fix it in seconds. If you think red-eye in photos occurs only in human images, you are totally wrong. If you’ve ever taken a photo of your dog or cat with a flash, you’ve probably seen their eyes glow a strange colour. However, the fixing process differs. Through this article, you’ll understand how to fix the red-eye effect and how it works in both human and pet photos.

What Causes Red Eye?

Right in the middle of each eye sits the pupil, a tiny gateway that opens and closes depending on how bright it is around you. In a dark room, it stretches wide to let in more light. A flash fires so quickly that the pupil has no time to shrink, so light travels straight through and hits the retina, which is packed with blood vessels. That light bounces back to the camera, and the photo appears with the red-eye effect.

It’s worst when the flash sits close to the lens, which is true for nearly every phone and compact camera. Party snaps, indoor family shots, and night portraits are the usual victims.

Fix Red Eye on Your Phone

Fixing red eye on your phone takes hardly ten seconds. Most phones have a built-in red eye remover, or free apps can do the job.

This is How to Fix Red Eye on Android

Open the picture in Google Photos, tap Edit, and look for the red tool option. Menu names change between phones and apps, so if you can’t find it, try a different gallery app.


Fixing on iPhone

  1. Open the photo and tap Edit.
  2. Tap the red eye button (it looks like an eye shape with a line through it) at the top of the screen.
  3. Tap each red eye pupil, then tap Done.

Red Eye Removal in Photoshop

When you choose Photoshop for red-eye removal, you’ll find a tool designed to control the redness and lighting while keeping the eyes’ colour intact. For red eye removal in Photoshop, follow these easy steps.


Quick Method: Red Eye Tool

  1. Duplicate your photo layer so the original image is safe.
  2. Zoom in on the eyes.
  3. Select the Red Eye Tool, which sits in the same group as the Spot Healing Brush.
  4. Click the red pupil. If the result looks too grey or too pale, adjust Pupil Size and Darken Amount in the top bar.

Manual Method: When the Tool Misses

  1. Use the Elliptical Marquee Tool to select only the pupil.
  2. Add a Hue/Saturation adjustment layer.
  3. Drag the saturation down to the red-out, then lower the lightness until the pupil appears natural.
  4. Leave the tiny white sparkles in the eye alone. It keeps the eye looking alive.
To remove the red-eye effect completely from deep-red or very small pupils, the manual route usually wins.
Wearing glasses? Reflections are a different problem.

Fixing Red Eye in Pets

Pets rarely glow red. They glow green, yellow, or blue due to a mirror-like layer behind their eyes called the tapetum lucidum, which helps them see in the dark. The red-eye tool hunts for red, so it skips right past them.

Fix It by Hand

  1. Zoom in and add a new layer. Grab a soft brush and pick a dark color from a part of your pet’s eye that isn’t glowing.
  2. Paint over the glowing area. Try the Color or Darken blend mode if it looks flat.
  3. Keep a small bright spot so the eye still has life.

How To Prevent Red Eye

Fixing red eye is easy. The easiest fix is making sure it never shows up. A few small habits before you shoot can save you plenty of editing time later.

Turn Up the Room Light

Bright surroundings make pupils less dilated, leaving less room for the flash to bounce. Open the curtains or switch on a lamp before you shoot.

Avoid Direct On-Camera Flash

Bounce it off a white ceiling or wall, or add a small diffuser. Softer light flatters skin, too.

Use Red-Eye Reduction Mode

The camera fires a quick pre-flash so pupils close before the real shot. Ask your subjects to wait for the second flash.

Move the Flash Away from the Lens

An off-camera flash or a bracket keeps the light from entering the eye head-on.

Ask People to Look Slightly Off-Camera

A small turn toward a window or a friend breaks the straight line that causes the glow.

Take a Quick Test Shot

Zoom in on the eyes before the moment passes.

Of course, real life isn’t always that tidy. At weddings, birthday parties, and busy events, you can’t pause the fun to rearrange the lighting.

Frequently Asked Questions

What causes red eye in photos?

Flashlight enters the wide-open pupil, reflects off blood vessels at the back of the eye, and bounces into the lens. It’s most common in dark rooms.
Open the photo, tap Edit, choose the red-eye option, and tap each eye. Free editing apps work the same way.
Use the Red Eye tool on the pupil, or select it and lower Saturation and Lightness with a Hue/Saturation layer.
Pet eyes usually glow green, yellow, or blue instead of red. Since the red-eye tool only looks for red, it can’t spot the glow, so you’ll need to paint over it by hand.
Yes. Google Photos, the iPhone Photos app, and several free editors include one at no cost.
Don’t shoot in the dark with the flash pointed straight at someone’s face. Add some light to the room, angle the flash off a wall, or use the red-eye reduction mode on your camera or phone.
Not after the shot is taken. The best option is to retake the photo with more light and no direct flash.
