Failing the Lang stereotest

I had an eye exam where I failed the Lang stereotest (had two line segments and a dot, they should have been in one line but I saw them shifted).

I do have perfect depth perception.
I have a blur in my right eye (right in the center where VA should be the best, 3 characters wide but better near that). Comprehensive eye exam resulted in no eye problems, no neurological issues either.
I'm 24, wearing glasses since age 6 (almost 7), first glasses was -1.0D both, astigmatism -1.5 left, -2.5 right.

The question:
Is it possible that I have amblyopia? Note that in my right eye the blur markedly ends left to the character I look at. Apart from the blur, BCVA in right eye maybe a tad bit worse than in the left.

TO REPEAT:  One diopter difference in the two eyes is normally not enough to cause amblypia.

Very well. I asked again because I didn't know this goes for astigmatism too.

There are many tests for stereopsis and the Lang is not the best by far. So it is possible using a different test such as the Titmus Random dot test you would be normal. That being said you should not have a small blur area in the center of your vision. To account for that you need to see eye MD have Amsler grid testing, maybe visual field and macular OCT.

Thank you for the answer. I had all of them all to be negative (completely fine). That is why I fear amblyopia. Do you think the astigmatism was strong enough to cause that and age 6 first glasses were too late?
Amblyopia means even with glasses the involved eye does not see 1-2 lines as good as the normal eye. If both of your eyes can read the 20/20 line with glasses by definition you don't have amlyopia.   Many people have 'dominant eye" and see better than the other just like dominant hearing ear.
That is the problem - I can't read through the chart with the right eye due to that blur I described earlier. And I'm unsure if the blur is due to amblyopia. How might one go for a diagnosis? AFAIK it is found in early childhood and I'm 24.
Also, could early childhood astigmatism (of -2.5D and -1.5D ) be the cause of amblyopia, given I got glasses at 6?
I just said if both your eyes have equal vision with glasses you don't have amblyopia.   The two primary causes of functional amblyopia are 1. strabismus (eye muscle problem)  eyes not pointed at the same object.  2. Aneisometrophia unequal refractive error. One diopter difference in the two eyes is normally not enough to cause amblypia.
Even one cyl difference of astigmatism? (same dioptre of myopia)
