Amblyopia is reduced vision in one or both eyes from abnormal visual development. Screening looks for unequal visual acuity, fixation preference, or eye alignment problems. Only a full eye exam can confirm the diagnosis and rule out other causes. Early detection supports better outcomes.

Parents watch for squinting, head turning, or closing one eye. Referral is recommended when screening is abnormal.
One eye seems weaker, a child favors one eye, or alignment appears off. Reading difficulties or poor depth perception can occur. Frequent eye rubbing or headaches may be noted. Screening picks up subtle cases.
Simple near and distance charts can hint at a difference between eyes. Cover one eye at a time and compare clarity without squinting. Home checks do not replace a full eye exam. Book an appointment if results differ.
Uncorrected refractive error, cataract, or retinal disease can also blur vision. A clinician rules these out during a dilated exam. Treatment depends on the true cause. Do not delay if vision seems unequal.
Vision screening starts in early childhood and repeats through school years. High-risk children need earlier and more frequent checks. Parents and teachers play a role in spotting signs. Follow advice from your local eye-care guidelines.
A lazy eye, or amblyopia, is reduced vision in one eye caused by abnormal visual development early in life. The brain favors one eye, leading to impaired vision in the other.
Amblyopia usually develops in childhood, but uncorrected refractive errors or visual deprivation can cause amblyopia-like vision loss in adults. Early detection during childhood is key.
Treatment involves correcting any refractive error with glasses or contact lenses, using eye patches or blurring drops on the stronger eye to encourage use of the weaker eye and sometimes vision therapy exercises.
