ametropic

Thân thiện

A person with an ametropic eye visits an optometrist for an eye exam.

Definition

1. Adjective:
   • Relating to ametropia: Describes an abnormal condition of the eye where light rays do not focus correctly on the retina, resulting in blurred vision.
   • Having a refractive error: Pertaining to an eye that is not emmetropic (not having perfect focus), such as being nearsighted, farsighted, or having astigmatism.

Usage Examples

• Adjective:
  • The patient's ametropic condition required corrective lenses. (The patient's refractive error required glasses or contact lenses.)
  • Ametropic eyes cannot focus images sharply on the retina without aid. (Eyes with this condition produce blurry images on the retina without correction.)

Advanced Usage

• "ametropic eye": The standard medical term for an eye with a refractive error.
  • The study compared visual acuity in emmetropic and ametropic children. (The research measured how clearly children with normal vision and those with refractive errors could see.)

Variants and Related Words

• Ametropia (n): The noun form referring to the condition itself.
  • Myopia and hyperopia are common types of ametropia. (Nearsightedness and farsightedness are common refractive errors.)
• Emmetropic (adj): The antonym, describing an eye with normal, perfect focus.
  • An emmetropic eye does not need corrective lenses for distance vision. (An eye with normal focus sees distant objects clearly without glasses.)

Synonyms

• Refractive error: A more common general term in optometry and ophthalmology.
• Vision defect: A broader, less technical term.

Notes on Meaning

This is a specialized medical and optical term. In everyday conversation, people typically use the names of specific conditions (like nearsighted, farsighted) rather than the general term "ametropic."
