The objective of this pilot study is to explore the effect of masking on subjective ratings for two daily disposable contact lenses.
The study hypothesis is masking will have minimal impact on subjective outcomes.
Allocation: Randomized, Intervention Model: Parallel Assignment, Masking: Single Blind (Subject), Primary Purpose: Supportive Care

The primary objective of this trial is to validate the improvements made to the OK inversion indicator. Visibility on eye and on finger will be assessed by the subjects
The objective of this study is to compare the clinical performance of senofilcon A lens with the stenfilcon A lens each for one week of daily disposable wear.
The aim of this study is to determine the clinical performance of comfilcon A in comparison to senofilcon C.
Prospective, multi-center, bilateral, double-masked, randomized, cross-over, daily wear, 1 month dispensing study (2 weeks each lens pair)
This study will compare the on-eye fitting characteristics of three types of contact lenses. Each lens pair will be worn for 30 to 45 minutes before assessment and the results will be comp...
With the increasing prevalence in myopia there is growing interest in active myopia prevention. This study aims to increase our understanding of parental attitudes to myopia development and control, a...
During the past 30 years, the prevalence rate of myopia has been increased dramatically. Myopia has become one of the leading causes of vision loss in some countries, whereas the mechanism of the main...
The purpose of this study was to determine the prevalence of myopia in a population of children in Sweden. Retrospective analysis of children in a region in Sweden referred to eye care from the nation...
High myopia and pathologic myopia are common causes of visual morbidity. Myopic pathology can affect all regions of the retina, though there is currently no classification system to distinguish anteri...
Myopia progression is thought to involve biomechanical weakening of the sclera, which leads to irreversible deformations and axial elongation of the eye. Scleral crosslinking has been proposed as a po...
Excessive axial myopia associated with complications (especially posterior staphyloma and CHOROIDAL NEOVASCULARIZATION) that can lead to BLINDNESS.
Plastic surgery of the SCLERA. This procedure is used frequently to prevent blindness and poor vision in patients, especially children, with MYOPIA.
A type of refractive surgery of the CORNEA to correct MYOPIA and ASTIGMATISM. An EXCIMER LASER is used directly on the surface of the EYE to remove some of the CORNEAL EPITHELIUM thus reshaping the anterior curvature of the cornea.
Detachment of the corpus vitreum (VITREOUS BODY) from its normal attachments, especially the retina, due to shrinkage from degenerative or inflammatory conditions, trauma, myopia, or senility.
A refractive error in which rays of light entering the EYE parallel to the optic axis are brought to a focus in front of the RETINA when accommodation (ACCOMMODATION, OCULAR) is relaxed. This results from an overly curved CORNEA or from the eyeball being too long from front to back. It is also called nearsightedness.
