A thorough ophthalmic examination of a child must include a refraction and this is often done with cycloplegia. In our study, we aim to determine at which age group a non-cycloplegic refr...
The study is used to verify the accuracy and repeatability of Smart Vision Labs Refractor in a pediatric population (between 5 and 16 years of age).
The assessment of the refractive state of the eye is a fundamental and important part of ophthalmic and optometric clinical practice. The development of an unsupervised online subjective r...
The purpose of the study is to compare the final glasses prescription based on refraction obtained with SVOne device to the final prescription obtained via subjective manifest refraction.
The purpose of prospective cohort study is to describe the developmental profile of refraction change in a large cohort of Chinese CC patients. The decisive factors to the range of myopic ...
To investigate longitudinal changes in refraction and biometry in Chinese adults.
To report normative data on visual acuity (VA) for near and distance, refraction, ocular alignment, ocular motility and stereo acuity in a cohort of children aged 4.5-7 years.
The USee device is a new self-refraction tool that allows users to determine their own refractive error. We evaluated the ease of use of USee in adults, and compared the refractive error correction ac...
To analyze the effect of birth weight on ocular morphology, refraction and visual function in early adolescents aged 12-15 years.
Negative refraction through a triangular prism may be explained without assigning a negative refractive index to the prism by using array theory. For the case of a beam incident upon the wedge, the ar...
Refraction of LIGHT effected by the media of the EYE.
Ocular manifestations secondary to various NEOPLASMS in which antibodies to antigens of the primary tumor cross-react with ocular antigens. This autoimmune response often leads to visual loss and other ocular dysfunctions.
The dioptric adjustment of the EYE (to attain maximal sharpness of retinal imagery for an object of regard) referring to the ability, to the mechanism, or to the process. Ocular accommodation is the effecting of refractive changes by changes in the shape of the CRYSTALLINE LENS. Loosely, it refers to ocular adjustments for VISION, OCULAR at various distances. (Cline et al., Dictionary of Visual Science, 4th ed)
A physical property showing different values in relation to the direction in or along which the measurement is made. The physical property may be with regard to thermal or electric conductivity or light refraction. In crystallography, it describes crystals whose index of refraction varies with the direction of the incident light. It is also called acolotropy and colotropy. The opposite of anisotropy is isotropy wherein the same values characterize the object when measured along axes in all directions.
Ocular disorders attendant upon non-ocular disease or injury.
