Diagnosis of bilat ptosis but I only see it in one eye? (Photo)

I was diagnosed with bilat ptosis and Dermatochalasis. I notice the ptosis of my one eye (my left) but I do not notice it in my right. The surgeon notated that they will perform ptosis repair and upper bleph to both eyes, but I’m somewhat concerned about ptosis surgery to my right eye when it looks normal to me and will result in my eye being too open, if that makes sense.
