Vision is often considered to be the most important sense, and good vision is crucial for maintaining quality of life in older age. In the Vision Lab at Baycrest, researchers use standardized charts like the ones you see when you get your vision tested. We use these to evaluate the ability to see very small detail, very faint stimuli, and small differences in depth. All of these visual functions can be affected in healthy aging, and significantly more so in individuals with dementia or those with eye diseases, such as cataracts, glaucoma or macular degeneration. In addition to standard eye charts, researchers at Baycrest use sophisticated visual displays such as VPixx Technologies (VIEWPixx – VPixx Technologies) to present visual stimuli with precision and control over factors, such as their duration and colour. This allows the researchers to study processes such as the perception of motion, facial identity, emotion and colour vision. The sophisticated display is also synchronized with other equipment, such as eye tracking devices, electroencephalography (EEG) and sound equipment.
