What is the difference between a lazy eye and strabismus?

Eye function. Lazy eye is a lay term usually used to designate the vision loss that occurs when the brain turns off the eye input because it is fuzzy or misaligned (double vision). We call it amblyopia. Strabismus is a label used when the eyes don't line up and focus on the same object. Some lay people use lazy eye for both issues.
A lot. Strabismus is the term used when the eyes do not move exactly synchronously. It is accompanied by double vision. If it is not corrected the brain ignores one of the images and in time we have a lazy eye (meaning the eye has little or no vision).

What is the difference between amblyopia (lazy eye) and strabismus (cross eyed)?

They can be mutual! Amblyopia results from the brain not learning how to use the information from the eye. Sources of that may be refraction (glasses), deprivation (eye covered by droopy eyelid), or strabismus (misaligned eye). There are many patient with perfectly aligned eyes that have amblyopia, and many with strabismus that have no amblyopia...
Big diffrence. Crossed eyes, may result in amblyopia of the eye less used. The brain will mask the image form that eye so patient doesn't see double. Crossed eyes in children less than 2 years old need to be straightened as soon as possible after reasonable amblyopia therapy if present. If eyes are straightened before age 2 3d visison usually develops. Between 2-4 it drops significantly. >4 not possible.
Different definition. Amblyopia is when the brain starts to turn one eye off and therefore it sees worse than the other eye. Strabismus is just a misalignment of the eyes. Often, strabismus can lead to amblyopia, but can occur without it. Amblyopia can occur without strabismus.

What is the difference between a lazy eye or a strabismus eye?

Lazy eye. They mean the same. The terms both refer to a defective eye muscle.
Alignment/vision. Strabismus is a simple failure of the eyes to line up & focus on the same point. There are several potential causes. Over time this might lead to lazy eye (amblyopia) where the brain decides to turn off the input of one eye if the images don't line up or one is fuzzier than the other. The "lazy eye" can sometimes be improved if alignment or weakness are fixed early, but may be permanent.

Is there a difference between a lazy eye and a strabismus?

Yes. Strabismus is the generic term for eyes that are out of alignment. A consequence of this in some cases is the popular term 'lazy eye' which indicates an eye which might drift out of alignment or an eye with lowered vision that cannot be improved (termed amblyopia). Not all lazy eyes are out of alignment but usually if the misalignment persists, one eye will become lowered in vision ('lazy').

What is the difference between strabismus and lazy eye?

Muscle/visual acuity. Lazy eye (aka amblyopia) is reduced visual acuity usually from abnormal development. Strabismus is an imbalance in the muscles of the eye which results in incoordination of the eyes, thereby affecting vision. Strabismus is a cause of amblyopia.

Lazy eye. Lazy eye (amblyopia) & strabismus are used interchangeably, having same meaning. Other names are crossed eyes or wandering eyes.

What’s the difference between strabismus and lazy eye? I though they were the same things, but now i’m reading that they’re not and they can each cause the other. I’m confused!

"Lazy. "lazy eye" is a lay term for amblyopia, where one eye is favored over the other by the brain. There are many reasons why this could happen, one of them is the presence of strabismus (eye turn). So you are correct in that strabismus is one of the causes of amblyopia.
Not the same. Strabismus means the eyes are crossed - when eyes are crossed in a young child the brain will get confused and ignore the crossed eye, leading to amblyopia or "lazy eye." other causes of a lazy eye can be a very high prescription in one eye that is asymmetric; again the brain starts to ignore the eye with the high prescription (because the image is blurred) and therefore develops amblyopia.

How do a lazy eye and a strabismus differ?

Both generic. Both these terms are generically used for ocular motility disorders. "lazy eye" is a laymen's term. Strabismus is the medical term for any misalignment of the eyes. There are many forms of strabismus and therefore may treatments.

Question for people who know about strabismus and lazy eye: which comes first?

Depnds on definition. Lazy eye can refer either to the fact that the eyes don't line up right (one eye is too lazy to keep up with the other), also known as strabismus, or to the loss of vision that occurs when the brain starts to favor one eye, (one eye is too lazy to talk to the brain) also known as amblyopia. Frequently amblyopia is caused by strabismus. Even doctors confuse them (hopefully not me).
Strabismus. Lazy eye, or amblyopia, is caused by not being able to use the eyes together in a child. Misaligned eyes, or strabismis, is the most common cause.

Is there a way to fix strabismus/lazy eye without surgery?

Rx May help. Ambliopia is the process where the brain ignores the "camera" picture from one eye because it is less clear or causes double vision. It can sometimes be improved if the weaker eye is strengthened (glasses), the stronger eye is patched or if the eye is lined up better with surgery. If the process has gone on too long, the brain ignores the fix & surgery is simply cosmetic.
