Sensitivity of the Ptosis Eye

The ptosis eyelid doesn't have the ability to protect the eye as well as the good eyelid can protect its eye due to the lesser functioning eyelid. For example, in cold or wind, the ptosis eye tends to water more easily. In bright sunlight, the ptosis eye will squint itself shut. We've had incidences of sunscreen getting into the ptosis eye resulting in severe swelling so we only use the stick sunscreens that cannot run. We try to encourage our son to wear sunglasses often so that he doesn't have to constantly squint that eye shut when out in sunlight. In most pictures taken outdoors, his ptosis eye is completely shut. And, of course, there are days in which his ptosis eye seems to be more droopy than other days; whether this is tiredness or something other. But, for the most part, his eye looks and functions great. And we couldn't be happier.
