A farsighted approach to tackle nearsightedness

Modern living may be contributing to an epidemic of nearsighted vision and related blindness. By 2050, it is estimated that half the world's population will suffer from low vision due to myopia, a condition where the eye ...

Models can predict long-term visual acuity in highly myopic eyes

For patients with high myopia, models for accurate prediction of the long-term visual acuity (VA) based on clinical and imaging information are feasible, according to a study published online Oct. 26 in JAMA Ophthalmology.

Secondhand smoke exposure linked to myopia in children

Secondhand smoke (SHS) exposure is associated with greater myopic refraction, longer axial length, and increased odds of developing moderate and high myopia, according to a study published online May 11 in JAMA Network Open.

Myopia

Myopia (Greek: μυωπία, muōpia, "nearsightedness" (AmE), "shortsightedness" (BrE)) is a refractive defect of the eye in which collimated light produces image focus in front of the retina under conditions of accommodation. In simpler terms, myopia is a condition of the eye where the light that comes in does not directly focus on the retina but in front of it. This causes the image that one sees when looking at a distant object to be out of focus but in focus when looking at a close object.

Eye care professionals most commonly correct myopia through the use of corrective lenses, such as glasses or contact lenses. It may also be corrected by refractive surgery, though there are cases of associated side effects. The corrective lenses have a negative optical power (i.e. are concave) which compensates for the excessive positive diopters of the myopic eye. Myopia is partly hereditary.
