• Refractive errorRelated: They are the most familiar way to compensate for refractive error.

• HyperopiaRelated: Plus-powered eyeglass lenses are a common way to correct hyperopic distance and near blur.

• MyopiaRelated: Concave spectacle lenses diverge incoming light so distant images focus farther back on the retina.

• LensRelated: Their prescriptions use lens power to compensate for focusing errors in the eye.

• AstigmatismRelated: Cylindrical or toric spectacle lenses correct astigmatic power.

• Convex lensRelated: Convex spectacle lenses correct hyperopia and presbyopia by adding converging power.

• OptometryRelated: Optometrists prescribe spectacle lenses to compensate for refractive errors.

• Thin lensRelated: Their corrective power is commonly specified using the thin-lens approximation.

• Iris ApfelRelated: Her oversized frames became a signature accessory and an instantly recognizable part of her image.
