When to worry about a child's eyes

Honestly, it's hard not to second-guess yourself when it comes to your kid's eyesight, right? So much of parenting is guessing. Some eye stuff is totally normal, just part of growing up. But other things? They can't wait. Knowing the difference could save their vision. I've pulled together what the experts say — the real red flags — so you know when to pick up the phone and when to relax.

What are the earliest warning signs of vision problems in babies?

Babies can't exactly tell you things are blurry. You gotta watch. By the time they're like three or four months old, they should be able to follow a toy with their eyes. If your baby isn't making eye contact? Or doesn't seem to notice a bright light? That's a big deal. Eyes that wander constantly — not just occasionally — that's another one. And if you ever see a white or cloudy spot in their pupil? That's an emergency, could be a cataract or something worse. Eye turning that sticks around past four months? Get it checked.

When is eye crossing or wandering in a child a problem?

Newborns' eyes cross sometimes. Their muscles are still figuring things out. Totally normal. But if it's constant after four months? That's when it's a problem. If one eye always turns in or out, the brain might start ignoring it. That's amblyopia — lazy eye. It's fixable, but only if you catch it early. If your kid's always closing one eye or tilting their head to see better? Those are signs too.

What physical symptoms indicate a serious eye infection or injury?

Pink eye is annoying but usually fine. Some stuff isn't. Head to the ER if you see:

• Serious pain that blinking doesn't help.
• Vision suddenly goes blurry or gone — especially after a fall or hit.
• Red eyes with light sensitivity and a headache. Could be something like iritis.
• Eyelids or the white of the eye swelling up bad, making it hard to move the eye.
• Thick, green or yellow pus with a fever.

Any chemical or sharp object near the eye? Don't mess around. Go straight to the ER.

How can I tell if my child needs glasses or has a refractive error?

Kids don't know what "clear" looks like. They just adapt. So you have to spot the clues. Things like:

• Squinting all the time, especially at stuff far away.
• Sitting right up against the TV or holding books an inch from their face.
• Headaches or eye strain after reading. They might complain.
• Rubbing their eyes like crazy, even when they're not tired.
• Avoiding close-up stuff like puzzles or drawing.

The American Academy of Pediatrics says check their vision at well-visits starting at age 3. If they fail a screening or show any of these signs, get a real eye exam.

When should I take my child to the emergency room for an eye problem?

Some stuff can't wait for a doctor's appointment. Go to the ER right away if:

• There's a visible injury — a cut on the eyelid or something stuck in the eye.
• Blood pools in the white part after an injury.
• Double vision that won't go away.
• One or both eyes look like they're bulging out.
• The pupil looks weird — different shape, size, or one's bigger than the other.
