Anisometropia is caused by common refractive errors, such as astigmatism, far-sightedness, and myopia, in one eye. [6] Anisometropia is likely the result of both genetic and environmental influences. [7] Some studies suggest, in older adults, developing asymmetric cataracts may cause worsen anisometropia.
Other symptoms can include eyestrain, headaches, and trouble driving at night. [1] Astigmatism often occurs at birth and can change or develop later in life. [5] If it occurs in early life and is left untreated, it may result in amblyopia. [2] The cause of astigmatism is unclear, although it is believed to be partly related to genetic factors.
Astigmatism is quite common. Studies have shown that about one in three people suffers from it. [6] [7] [8] The prevalence of astigmatism increases with age. [9] Although a person may not notice mild astigmatism, higher amounts of astigmatism may cause blurry vision, squinting, asthenopia, fatigue, or headaches. [10] [11] [12]
