B vitamins are a group of water-soluble vitamins that play important roles in cell metabolism. A deficiency in B-2 might also result in eye problems such as redness and irritation. You might also experience eye fatigue and light sensitivity. Vitamin B-2 might also help prevent cataracts, an eye condition that gradually affects the clarity of the lens inside the eye, resulting in cloudy vision. A deficiency in vitamin B-1, also known as thiamine, might cause eye muscle weakness and uncontrollable trembling. In rare instances, a deficiency in vitamin B-12 might also result in eye movement disorders. Vitamin B-12 is a nutrient found in many animal-based foods, and people who follow a vegetarian or vegan diet have a higher risk for a deficiency. If you have low levels of vitamin B-12, you might experience loss of vision or double vision as a result of inadequate intake. B vitamins can be found in a variety of foods such as meat, soy beverages, grains and vegetables and fruits.
