  • (12) The significant difference found between early- and late-onset myopes is suggested as a possible reason for the inconclusive results of some previous studies.
  • (13) A 56-year-old myope developed a retinal detachment of the macular area and the temporal quadrants in his left eye that harbored a temporally-located pit of the optic nerve head.
  • (14) Both forms of contact lenses placed greater accommodative requirements on the myope than did spectacle correction, but no significant difference was found between the 2 types of contact lenses in this respect.
  • (15) We measured ocular dimensions and determined the crystalline lens powers in 19 myopes and 19 emmetropic subjects matched for age, gender, and ethnic origin.
  • (16) The items which discriminate in favor of the myopes are essentially those which require academic achievement and individual creative performance, whereas the items which are in favor of the nonmyopes are those which require business and selling skills as well as outdoor types of activities.
  • (17) In general myopes exhibited a personality pattern of introversion, whereas hypermetropes maintained a pattern described as extroverted.
  • (18) Contrast sensitivity values were taken on seven astigmatic (cylinder correction under 1.00 diopter) and eight spherical myopes using the Vistech VCTS 6500 System.
  • (19) Most myopes do not progress in young adulthood (about 20 to 25 years of age).
  • (20) Even when allowances were made for the inherent variability of measurement of the VOR gain, myopes tended to have lower gains and hyperopes higher gains.

Presbyope


Definition:

  • (n.) One who has presbyopia; a farsighted person.

Example Sentences:

  • (1) This paper discusses methods for improving vision in the dental operatory and details a new design for eyeglasses suitable for the presbyopic dentist.
  • (2) Emmetropic presbyopes are not used to wearing bifocal or progressive-power lenses all the time.
  • (3) At the presbyopic age, education, accurate close work, and poor distant vision were connected with the wearing of spectacles.
  • (4) A total of 108 presbyopes were fitted with lenses, and after 12 months 46% were still wearing the lenses.
  • (5) The authors have examined the repeatability of refractive error measures (retinoscopy, subjective refraction, and Canon R-1 autorefraction, noncycloplegic and cycloplegic), axial dimension measures (Allergan-Humphrey A-scan ultrasound), and corneoscopy (keratometry and KERA photokeratoscopy), and the agreement between different refractive error and corneal measurement methods on 40 pre-presbyopic normal adults.
  • (6) A 60 year-old black man when seen in consultation for foreign body sensation and presbyopic complaints was noted on ophthalmoscopy to have bilateral pigment epithelial defects.
  • (7) We found that fusional vergence ranges in presbyopes corrected with MV were not substantially different from those measured under full binocular nearpoint correction.
  • (8) The effects of monovision (MV) contact lens wear on the performance of occupational-type nearpoint tasks was evaluated on 18 presbyopic subjects (ages 44 to 67 years) by comparing MV performance (MV condition) to that with distance contact lenses with reading glasses (BV condition).
  • (9) The first three stages are those proposed by Bausch & Lomb as the Presbyopic Fitting System.
  • (10) There are several hydrogel bifocal designs that are possible for the presbyope.
  • (11) Even without the aid of echometry and objective aniseikonic measurement, Rule 1 enables us to prescribe combined contact lens correction for 80% of all presbyopic patients, thus enabling them to regain comfortable binocular vision.
  • (12) However, pre-presbyopic individuals with accommodative or vergence disorders who respond favorably to plus lenses at near may be good candidates for bifocal contact lenses.
  • (13) The aging (presbyopic) pilot has difficulty with near vision which can be a serious problem in the cockpit because of the complexity and uniqueness of his visual tasks.
  • (14) This article deals with a type of pulpit spectacles which have been specially developed for emmetropic presbyopes.
  • (15) Several actual cases were presented to show the problems encountered with flight deck vision in the middle-age presbyopic pilot both in the simulator and in flight.
