There is no way to accurately predict the chances of passing on myopia to an offspring when both parents have myopia, as opposed to the chances of passing it on when the parents do not have myopia. Myopia is a polygenic condition and it is not possible to project the risk of inheritance from family history or the amount of myopia the patient has. However, a rough prediction can be made based on the patient’s family history and the amount of myopia in the parents. The risk of myopia in the offspring is higher if there are multiple myopes in the family and if both parents are highly myopic, the risk of myopia in the offspring is also higher. However, the formation of myopia is the result of multiple factors, in addition to genetic factors, bad eye habits are also important causes of myopia, even if there are genetic factors, but can develop reasonable eye habits, can also be effective in preventing the occurrence of myopia.
