I have this also. Did you ever figure it out?
Hi,
How are you? What other symptoms are present? If there was no history of trauma, the white line could be physiologic or pathologic in nature. While the lid margin is divided into ciliary and lacrimal portions and the margin of the ciliary portion which carry the lashes is formed by the grey and white lines, this should be checked by an eye specialist for proper evaluation especially if your mom also have this. Direct clinical examination is important. Take care and do keep us posted.
Have you used coconut oil on it? Try that I have the same thing just noticed on left eye! Eye has become blurry..going to get it checked out..
