How can I determine if I have ptosis or amblyopia? (Photo)

That would mean a life long history of reduced vision in one of your eyes.  Ptosis is heaviness or drooping of the upper eyelids.  You photo suggests mild upper eyelid ptosis.  If you are concerned, see a general ophthalmologist ( eye M.D.) for a comprehensive examination.

Hi,Ambliopia, or "lazy eye" is a congenital condition that affects vision and the appearance of the eye.  As part of the appearance issues, a drooping (or ptotic) eyelid can be present with or without problems in alignment of the gaze.  The vision problems are more complex and can involve processing images with the affected eye.  The easiest explanation is that the unaffected eye is dominant - it is the one you prefer especially when aiming or looking through a peephole.  Many times, the drooping of the eyelid can be overcome with effort or certain movements.With primary  ptosis, there is mechanical disruption of the system that keeps your eyelid at proper height.  This would not be completely corrected with effort or special eye movements.  So, it would be determined by examination.  It is important to note that ptosis can be a symptom of other issues, so it would be wise to rule these out before you pursue correction.  You can see an ophthalmologist for a complete evaluation.  If your diagnosis is primary ptosis, then surgical correction is an easy process that can be done awake or under sedation.I hope this clears it up for you!
