Abstract

Background: Accurate refractive assessment in children and young adults is critical to prevent amblyopia and strabismus, conditions that may arise from uncorrected hyperopia. Although noncycloplegic autorefractors and photoscreeners are increasingly used for vision screening due to their practicality and high testability, residual accommodation often introduces systematic measurement bias. The debate regarding the necessity of cycloplegia has intensified, particularly in large-scale epidemiological studies and screening programs, highlighting the need for an evidence-based synthesis.

Abstract

Visual skills are increasingly recognized as critical to athletic performance, yet it remains unclear whether participation in specific team sports is associated with enhanced visual function.

Abstract

Background: Sports vision training improves perceptual–motor skills crucial for performance and injury prevention. Despite proven benefits, little is known about its perception and use among coaches in Portugal. Methods: A cross-sectional online survey was completed by active coaches from various sports, gathering sociodemographic data, awareness of visual training, perceived importance of ten visual skills, and implementation in training plans.

Abstract: Knowing that the prevalence of crystalline cataracts after 40 years is relatively high and that exposure to UV rays is a factor for its appearance, since the lens is an absorber of these rays, it was intended with this pilot study to verify the relationship between the appearance of crystalline nuclear sclerosis and the time that patients take from the use of ophthalmic lenses, since they absorb most of these rays under normal conditions of use.
