Krill oil is also believed to support visual health, particularly in terms of visual acuity (sharpness of vision) and eye health. The omega-3 fatty acids, EPA and DHA, present in krill oil are essential for the normal functioning of the retina, which is the light-sensitive tissue at the back of the eye. They provide several benefits for vision:

1. Retinal Development: DHA is a major component of the retina, and it is crucial for its development and maintenance. Adequate levels of DHA support the structure and function of the retina, which can contribute to improved visual acuity.
2. Anti-Inflammatory Effects: The anti-inflammatory properties of omega-3 fatty acids can help reduce inflammation in the eyes and protect against conditions like dry eyes, which can affect visual acuity.
3. Antioxidant Activity: Krill oil contains astaxanthin, a potent antioxidant. Astaxanthin has been shown to have protective effects on the eyes, reducing oxidative stress and supporting overall eye health.
