If there is a large difference in vision between the two eyes of the patient, eye discomfort such as strabismus, deviation of vision, and visual fatigue may occur.
1. Strabismus: If the difference in visual acuity between the two eyes is too large, the eye with better vision will be used more, while the eye with poor vision will be in a state of “abandonment”, which may result in eye deviation, such as obsolete external strabismus.
2. Visual deviation: When there is a big difference in the visual acuity of both eyes, because of the difference in the clarity of imaging between both eyes, there will be errors in the judgment of the overall sensory, spatial and positional sense of the same object, which will easily lead to visual deviation and make it more difficult to carry out fine movements.
3. Visual fatigue: Due to the large difference in visual acuity between the two eyes, patients using the dominant eye for a long period of time will easily increase the burden on the eye, and symptoms of visual fatigue such as dryness, swelling and pain may occur, while amblyopia may occur when the non-dominant eye is out of use for a long period of time.
It is recommended that patients with a large difference in vision between the two eyes should consult a doctor in time to evaluate their condition and follow the doctor’s instructions for treatment to improve their vision.
