Symptoms of Defective Vision


Here are some of the common signs and symptoms that indicate defective vision:

	Blurred distance vision (in case of nearsightedness)
	Blurred near vision (in case of farsightedness)
	Difficulty distinguishing certain colors, commonly red-green (in case of colorblindness)
	Poor or no vision at night (in case of night blindness)
	Eye discomfort
	Squinting and frowning
	Eye straining
	Watery eyes
	Frequent headaches

Natural Cures

Defective vision can be cured with corrective lenses or with surgery such as LASIK or cataract surgery. Natural cures and herbal remedies can relieve some of the symptoms that are associated with vision defects such as eye discomfort, straining, headaches, and watery eyes but they cannot completely cure defective vision.

Vitamin A

Deficiency of vitamin A or retinol is often the cause of vision defects. Vitamin A cannot be derived from plant sources so vegetarians and vegans are typically at a risk of having vitamin A deficiency. However, some plant sources contain carotenoids such as beta-carotene that act as provitamins converted into vitamin A during absorption. Here are a few sources of vitamin A:

	Consume nutrient-rich vegetables and fruits such as spinach, broccoli, peas, carrots, mangoes, tomatoes, peaches, and cantaloupes. Nuts such as pistachios, chestnuts, pecans, almonds, and hazelnuts also contain vitamin A.
	Consume animal sources such as liver, milk, butter, cheese, and whole eggs.

Chicory

Chicory or endive is one of the richest sources of vitamin A and is considered to be a nourishing food that ensures a healthy optic nerve and muscular system. A concoction made of carrot juice, celery juice, parsley juice, and chicory juice can help to cure vision defects such as nearsightedness.
