The eyes are key organs in the body. Like other organs, there are many conditions that can attack them. For instance, illnesses like rheumatoid arthritis, contribute to dry eye. Dry eye can be painful and make one’s vision blurry. Proper lubrication is key to eye function and health. The constant dry eye can lead to inflammation of the eye tissue. People with this problem have to use artificial tears to get relief. Severe cases may require prescription drops.
