What's the difference between farsightedness and nearsightedness?
Farsightedness
Definition:
(n.) Quality of bbeing farsighted.
(n.) Hypermetropia.
Example Sentences:
(1) It should include a cycloplegic refraction to tule out excessive farsightedness, nearsightedness, astigmatism, or unequal refraction in the two eyes.
(2) The origin of the apparent farsightedness as revealed by retinoscopy in smaller eyes was investigated by using monochromatic retinoscopy on wild rabbits.
(3) This is due to the wisdom and farsightedness of King Abdul Aziz Al-Saud, who, to reorganize the Saudi-Arabian people and establish his sovereignty, adopted the divine law of the Koran, the Sharia, as the only law applicable to control all individual and social relationships and to combat crime.
(4) The Finnish Twin Cohort material was used to estimate genetic and environmental effects in the etiology of hyperopia (farsightedness).
(5) During his time at Glasgow, Bob had isolated stem cells from early rabbit embryos, work which similarly displayed the farsightedness that pervaded his research.
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.
