La baixa visió és molt desconeguda per la població general, cosa que dificulta molt el dia a dia de les persones que pateixen baixa visió. Això fa que no rebin el suport i l'empatia dels seus conciutadans
Amblyopia occurs in 3 – 5% of the population and is defined as a unilateral or bilateral loss of vision resulting from abnormal visual stimulation during the early years of visual development. In clinics, the diagnosis of amblyopia largely relies on a decreased monocular or binocular visual acuity, the absence of any pathology that would explain the visual deficit, and the presence of an amblyogenic factor (usually strabismus or anisometropia). However, several other visual functions such as contrast sensitivity, stereopsis, eye movements or visual processing are also affected in amblyopia. This work is focused on the effects of amblyopia on eye movements. There are extensive research studies which have reported ocular motor deficits in the amblyopic and fellow eyes, such as longer saccadic latencies and reduced saccadic amplitudes, low pursuit gain, or fixation instability. These studies have been done in very controlled laboratory conditions, presenting visual stimuli on a computer screen and recording eye movements with an eye-tracker. Although these findings are relevant in the context of basic research on the neural mechanisms of amblyopia, the consequences of these ocular motor deficits in daily life are unknown. In this work, eye movements of children with amblyopia will be measured with a portable eye-tracker while they do naturalistic tasks which require a combination of visuospatial abilities. Their ocular motor behavior will be compared to that of age-matched typically developing children to determine how amblyopia affects their performance in daily life activities. This work is part of a bigger project that the research group VISPEC (Visual Optics and Spectral Imaging Group) from the CD6 (Centre for Sensors, Instruments and Systems Development) is carrying out at the moment.

El punt de partida d'aquest TFG consisteix en una cerca bibliogràfica sobre aspectes relacionats amb la compra online de lents de contacte (LC) i els seus accessoris. Es dissenyarà un enquesta on es demana a usuaris/es de LC si compren online, el motiu, etc. Això es complementarà amb una anàlisi de les dades recollides.
Jugar a videojocs d'acció comporta una disminució del parpelleig. Ara bé, investigacions recents indiquen que els jugadors/es habituals de videojocs d'acció no tenen una simptomatologia en els paràmetres de sequedat ocular com ara el TBUT o el OPI. Ja que el parpelleig va lligat a processos atencionals, la hipòtesi de l'estudi és estudiar si els patrons de parpelleig són diferents en jugadors/es habituals de videojocs d'acció comparats amb no jugadors habituals.
Es farà una cerca bibliogràfica de les diferents opcions de control de miopia, avantatges, inconvenients, anàlisi del mercat existent, etc. Hi ha la possibilitat d'acompanyar-ho amb un assaig clínic, encara per confirmar
El objetivo de este trabajo es analizar cómo la simulación de baja visión mediante filtros Bangerter afecta el rendimiento en diferentes tareas visuales (lectura, búsqueda visual, reconocimiento de objetos) utilizando un eyetracker. El estudio pretende cuantificar el impacto de las distintas densidades de los filtros en la eficiencia y estrategias de lectura, aportando información relevante para el diseño de adaptaciones y ayudas visuales en personas con baja visión.
Existen muchos estudios de la influencia de diferentes demandas prismáticas a nivel postural estático y dinámico, incluso en ámbitos de cognición. Por ahora no se ha estudiado la relación de diferente demandas prismáticas, foria, reservas, ojo y pie dominante en el control postural dinámico.
