Is There A Difference Between A Lazy Eye And A Strabismus
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. ...Read more
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. ...Read more
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. ...Read more
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!
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. ...Read more
Maybe, maybe not: Ambliopia (lazy eye) 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. ...Read more

It depends: Contact lenses cannot be used for prism correction of strabismus. Glasses are the better choice for this. For lazy eye, in some cases contacts can work well to correct vision in the lazy eye. It depends on the cause of the lazy eye. See your local ophthalmologist for a thorough exam. ...Read more
Confusing question: Proper vision requires brain input of 2 similar sharp images by well aligned eyeballs. If one eye is sharper than the other, or alignment is bad, the brain may turn off one eye to stop a blurred image. If the vision is off in one eye for an extended period (yrs), amblyopia (lazy eye) can be permanent. Alignment surgery may not hold without vision to keep it on tract. Revision may be necessary/cosmetic ...Read more

I am assuming your blind left eye has become "lazy." if the eyeball itself looks normal, but is just misdirected, you probably are a good candidate for strabismus surgery.
Pediatric ophthalmologists are specialists in adult strabismus. Have a visit with one of these!

Two forms of lazy: Amblyopia means the eye cannot see well despite the appropriate prescription being worn (usually 20/40 or worse). The eye can be well aligned but the brain does not use its information. It can be caused by something blocking vision (cataract) or the eye not being aligned. Strabismus means the eye is not aligned, and will lead to amblyopia if not treated. ...Read more
By different tests: The term "lazy eye" means different things to different people. Some equate it with crossing eyes. Lazy eye in the sense of reduced vision is diagnosed by measuring the vision, crossed eyes by measuring how much the eye deviates. Crossing eyes in adults are usually treated by surgery. Amblyopia in general can not be improved in an adult. ...Read more
Different causes: These terms are interchangeable. Strabismus usually refers to turning in or out of the eyes with onset in childhood. This can be due to a refractive error, deprivation of vision or other congenital problems. Adults can also have crossing of the eyes for different reasons, including nerve problems and decompensation of corrected childhood strabismus. ...Read more
What's the difference between strabismus & cranial nerve palsies that effect the eyes? Can cranial nerve palsies cause strabismus?
Different patterns: Strabismus is the generic term for eye misalignment of any cause. If from childhood, the eyes are separated about the same in all positions. If from cranial palsy, the degree of separation goes from normal away from the action of the muscles, to a very wide difference in the direction of the action of that muscle. An ophthalmologist can usually readily make this distinction. ...Read more
My son is 22 months old & has a slightly unfocused lazy eye. What can I do? I tried patching for 3 weeks but it didn't make a difference.
Pediatric eye doc: I hope your son is under the care of pediatric ophthalmologist. There are set criteria and procedures for patching to help resolve strabismus in babies. Unsupervised patching can actually produce poor vision in the "good" eye. Three weeks is not a sufficient time to see a substantial change. You should talk to your doctor about the time frame where you will see a change and his expectations. ...Read more
I m 19 yrs n have a lazy eye. It isn't deviated. Is there possibility of eye getting deviated in future? D lazy eye can't c well even using right glasses
Possible: Lazy eye, or amblyopia, describes an eye that cannot see well (typically more than 20/40) even with the best prescription lenses. It can be associated with a deviated eye. If the eye has never deviated, it is lees likely that it will as you get over, but there is always a slight possibility. If it was deviated as a child, there is a greater chance that it will deviate later in life. ...Read more
Non-working = lazy: Lazy eye refers to several issues that can cause the brain to quit accepting input from an affected eye, so it is not working =lazy. Example: 1 eye presents a sharp image to the brain, 1 a fuzzy image. The brain chooses to keep the sharp image & quit "looking" at the other image. Timed patching of the good eye makes the brain keep using the weak eye. The eye dr works to improve the weak eye. ...Read more
No: Lazy has come to mean a few things. If you mean the eyelid is droopy, this will not change on its own and should be evaluated by an oculoplastic surgeon/ophthalmologist to rule out horner's syndrome or other causes and then possibly corrected with surgery. If the eye itself is turning in or out, this should be evaluated by a pediatric eye doctor asap. Both problems can cause loss of vision. ...Read more
Maybe: Therapy for amblyopia depends greatly on your age. If you are a child less than 7-8 years of age there is good potential for permanent visual improvement. Older than this, therapeutic benefits decline but may still be attained up through the teenage years. Of course, getting the best glasses or contact lenses can help as well. ...Read more
