Very Low Risk
It is not based on facts and not true that breastfeeding would cause a harmful effect on neither the child nor the eyes of the mother.
At latest update not a single study was found that would relate myopia to breastfeeding among 110,716 articles that have been collected about myopia or refractive defects at the US National Library of Medicine. In a single study, the authors stated that possible ocular changes occurring in pregnancy may persist within breastfeeding period (Sharma 2006).
So it is an urban legend, which is occasionally disseminated by some professionals, yet by no means based on scientific results.
Prolactin levels are similar in myopic than non-myopic subjects (Angi 1993).
An association between myopia and vitamin D deficiency (Yazar 2014) has been found.
There is a controversy about a possible relationship between pregnancy and childbirth (albeit not breast feeding) with refractive defects and other ocular pathologies (Neri 1985, Manges 1987, Dinn 2003, Sharma 2006, Mehdizadehkashi 2014). On which, whether any change occurs, it disappears soon after childbirth (Pizzarello 2003, Ebeigbe 2012).
Evidence is not consistent on the protective effect of breastfeeding on development of myopia in children (Wu 2019, Liu 2018, Rudnicka 2008, Sham 2010, Shirzadeh 2016).
Any type of myopia is not a contraindication for breastfeeding.
