What's the difference between nearsighted and nearsightedness?
Nearsighted
Definition:
(a.) Seeing distinctly at short distances only; shortsighted.
Example Sentences:
(1) The World Bank and the UN refugee agency have called for a “paradigm shift” in the way the world responds to refugee crises such as the Syrian emergency, warning that the current approach is nearsighted, unsustainable and is consigning hundreds of thousands of exiled people to poverty.
(2) Evaluation of the performance of 17-18-year-old high school students on standard intelligence tests confirms previous reports that nearsighted persons consistently achieve scores approximately eight I.O.
(3) Even the normal or slightly nearsighted eye may not be able to focus the indigo-violet wavelengths of light on the retina.
Nearsightedness
Definition:
(n.) See Myopic, and Myopia.
Example Sentences:
(1) It should include a cycloplegic refraction to tule out excessive farsightedness, nearsightedness, astigmatism, or unequal refraction in the two eyes.
(2) Comparison of tests administered to the same students 10 years earlier suggests that the intellectual gain precedes the development of nearsightedness.
(3) When treating nearsightedness with radial keratotomy, that is, by causing lesions with a diamond-knife, the individual results are quite difficult to predict reliably.
(4) However, comparison with other instruments for examining near heterophoria justifies the conclusion that heterophoria or nearsightedness due to errors of refraction can be determined more easily with this instrument and hence treated more appropriately.
(5) Many investigations have been carried out during the last 150 years to detect factors which cause nearsightedness (myopia).
(6) The procedures involve reshaping the cornea to compensate for the optical anomalies of astigmatism and nearsightedness.
(7) Data are presented on the family distribution of nearsightedness, including the frequency of the disorder in the children of two myopes.
(8) This study examines the relationship of subjective glare to refraction and visual acuity, respectively, 1 year after surgery in 435 patients who underwent radial keratotomy for nearsightedness in the Prospective Evaluation of Radial Keratotomy (PERK) study.
(9) The intellectual gain precedes in time the development of nearsightedness.
(10) Young children with surgically removed lenses and extreme nearsightedness can benefit from contact lenses, but their parents may need instruction to teach their children to accept lenses.
