Vision is our most precious special sense. Nearly half of the human brain is engaged in vision-related activities. Vision loss is any reduction in the ability to see, including blurred vision, cloudy vision, double vision, blind spots, poor night vision, and loss of peripheral vision (tunnel vision). Vision loss may affect one or both eyes, it may occur gradually or suddenly, and it may be partial or complete. Vision changes may originate in the eyes themselves or may be caused by many different conditions that affect the brain or even the whole body. https://ipsnews.net/business/2020/09/10/revision-review-the-new-vision-supplement-real-customer-review/
