Also found in: Dictionary, Thesaurus.
improved near vision in the aged as a result of increased refractivity of the nucleus of the lens causing myopia.
Synonym(s): senile lenticular myopia
1 an improvement in near vision that may develop in aging as a result of increasing refractivity of the lens nucleus related to development of a nuclear sclerotic cataract.
2 an early increase in the index of refraction of the lens, resulting in a decrease in hyperopia and an increase in myopia.
3 clairvoyance, precognition. See also senopia.
