Abstract‐Beginning with the seventeenth century, when the main scientific foundations were laid, an account is given of the development of various clinical techniques for the assessment of visual acuity and amctropia. Both subjective and objective methods of refraction, with associated instrumentation, are reviewed. Among the more recent techniques described are meridional refraction, astigmatic decomposition, and photorefraction. In various fields, some little known contributions of particular… 
Subjective Refraction: Principles and Techniques for the Correction of Spherical Ametropia
1. A subjective refraction where the result depends on the patient’s ability to discern changes in clarity. This process relies on the cooperation of the patient. 2. An objective refraction (usually
Comparison of Two Different Photorefractors with Skiascopy Measurements in Healthy Children
Refractive values determined by two photorefractory devices with refractive values obtained by skiascope after cycloplegia with 1% cyclopentolate hydrochloride in healthy children are compared with each other.
Loss of Corrected Visual Acuity According to Different Meridional Visual Acuity in Astigmatic Eyes
The final glasses prescription has to be given with full correction because continued under-correction for astigmatism causes meridional VA difference, and the difference is higher with under 1.0 monocular VA.

Part of the history of optometry (and linked branches of optics) research and its publication is discussed and the question of whether the breadth, quality and quantity of Optometry journals are finally starting to catch up with the high quality of optometric research is asked.
Componentes oculares em anisometropia
The eyes with lower ametropia presented correlations more frequently observed in emmetropia, while the eyes with higher ametopia did not present the same correlations observed inEmmetropic eyes.

To specify a keratoprosthesis (KPro) power value for use with an intraocular lens (IOL), the power value must be specified with respect to the lens itself.
Study of Kenyan Optometrists View on Future of Optometry and Prospective Impact on Public Health
The key recommendations was to lobby for regulation of optometry practise and there is need for public awareness on what is optometry and their role in the eye care.

Photorefraction: a technique for study of refractive state at a distance.
The technique provides an objective method for estimating the refractive states of both eyes of a subject simultaneously, under more-or-less-natural circumstances, and may find practical application in the visual screening of very young children.
