Low vision can make it harder for a visually impaired person to encode (learn) and recall visual memories because the visual information is not available. This can lead to difficulty remembering things they have ‘seen,’ such as faces, objects, or locations. Additionally, if a person with vision impairment is unable
What is the Best Lighting for Low Vision?
Optimal lighting for those with vision loss varies. Most with low vision benefit from increased illumination, while some visually impaired are light-sensitive and function better at lower light levels. Sunlight is a natural light source that has the full spectrum of wavelengths. Most with low vision find that natural lighting
Do Omega-3 Supplements Help Your Eyes?
