Ptosis is an abnormally low position (drooping) of the upper eyelid.

• The drooping may be worse after being awake longer, when the individual's muscles are tired.
• This condition is sometimes called "lazy eye", but that term normally refers to amblyopia. If severe enough and left untreated, the drooping eyelid can cause other conditions, like amblyopia or astigmatism.
• This is why it is especially important for this disorder to be treated in children at a young age, before it can interfere with vision development.
• Ptosis can interfere with reading and can lead to head & brow ache from straining to elevate your eyelids
• Adjust the slider to simulate the LOSS OF SUPERIOR and PERIPHERAL VISUAL FIELD as the eyelid becomes more ptotic.
