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.

Clinical Validation of the New Print on Focus DAILIES Toric
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 Clinical Comparison of Senofilcon A and Stenfilcon A Contact Lenses
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.
Performance Comparison Between Comfilcon A and Senofilcon C Lenses
The aim of this study is to determine the clinical performance of comfilcon A in comparison to senofilcon C.
Performance Comparison Between Fanfilcon A and Senofilcon C Sphere Lenses
Prospective, multi-center, bilateral, double-masked, randomized, cross-over, daily wear, 1 month dispensing study (2 weeks each lens pair)
An Evaluation Of The Fitting Success Rate Of Senofilcon A Soft Contact Lenses In Three Designs.
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...
Novel Myopia Genes and Pathways Identified From Syndromic Forms of Myopia.
To test the hypothesis that genes known to cause clinical syndromes featuring myopia also harbor polymorphisms contributing to nonsyndromic refractive errors.
High myopia in Greater Beijing School Children in 2016.
To assess prevalence and associated factors of myopia and high myopia in schoolchildren in Greater Beijing.
To evaluate the incidence and progression of myopia and factors associated with progression of myopia in school going children in Delhi.
Assessment of Clinical Trials for Devices Intended to Control Myopia Progression in Children.
The increased prevalence of myopia in the United States and other regions of the world, and the sight-threatening problems associated with higher levels of myopia have led to great interest in researc...
Gene Expression and Pathways Underlying Form Deprivation Myopia in the Guinea Pig Sclera.
Posterior scleral remodeling accompanies myopia. In guinea pigs developing myopia, the region around the optic nerve (peripapillary zone, PPZ) rapidly expands followed by inhibition in eye size in the...
Myopia, Degenerative
Excessive axial myopia associated with complications (especially posterior staphyloma and CHOROIDAL NEOVASCULARIZATION) that can lead to BLINDNESS.
Scleroplasty
Plastic surgery of the SCLERA. This procedure is used frequently to prevent blindness and poor vision in patients, especially children, with MYOPIA.
Photorefractive Keratectomy
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.
Vitreous Detachment
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.
Myopia
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.
