Antimetropia: When each eye sees differently

Q: What are the symptoms of antimetropia?

While not everyone has noticeable symptoms, people with antimetropia may find that one eye sees more clearly than the other, which may cause headaches, dizziness, nausea, and often poor depth perception.

Q: How rare is antimetropia?

Antimetropia occurs in about 0.1% of the population.

Q: What causes antimetropia?

Antimetropia can occur when each eye develops different focusing abilities, often due to differences in eye shape, genetics, aging, or previous eye surgeries or injuries.

Q: How is antimetropia corrected?

Antimetropia can be corrected with eyeglasses, contact lenses and refractive surgery, although contact lenses are often the preferred option.

Q: What can happen if antimetropia is not treated?

If left untreated, antimetropia can sometimes lead to amblyopia, or “lazy eye.” Amblyopia occurs when the brain and eyes don’t work together as well as they should, which can affect vision in the weaker eye.

Q: What is the difference between hyperopia and myopia?

Myopia makes it harder to see things in the distance (nearsightedness), while Hyperopia makes it harder to see things up close (farsightedness).
