Beneficial for visual function
The 'beneficial for visual function' property of a dog food ingredient means that it contains nutrients that can contribute to the health and function of your dog's eyes. Such nutrients usually include antioxidants, vitamins and specific fats that are essential for maintaining good vision.
For example, vitamin A is an important nutrient that is essential for visual function. It helps maintain retinal health and plays a role in improving night vision. Omega-3 fatty acids, particularly DHA (docosahexaenoic acid), are also important for eye health as they have anti-inflammatory properties and help to maintain the cell structure of the retina.
Lutein and zeaxanthin, two types of carotenoids, are well-known antioxidants found in some vegetables that can protect the eyes from harmful light exposure. These nutrients can help reduce the risk of eye disease and support overall vision.
Incorporating ingredients with these nutrients into your dog's food can therefore have a positive impact on your dog's eye health and help to maintain or even improve their visual function over time.
