Magnesium is an important nutrient for your body, helping to build bones, create energy and regulate levels of other nutrients in your body. Despite the many roles and benefits of magnesium in your body's processes, magnesium cannot cure or reduce the number of floaters in your vision. Understanding eye floaters will help you discuss your condition with your doctor and understand why magnesium will not change these spots in your vision.
Cause
The back chamber of your eye contains vitreous, a substance with a jelly-like composition. As you age, the components of the vitreous may clump together, forming small black floaters in your vision. The vitreous may also shrink and tug at the retina, the lining of the back of your eye. If the retina tears, this may result in floaters in your vision, particularly if the tear causes bleeding.
Treatment
Medications, magnesium and other nutrients will not help floaters. In most cases, your doctor will recommend leaving the floaters alone, in hope that the spots will settle out of your visual field. If you have a significant number of floaters or a large floater that blocks part of your vision, your doctor may recommend a vitrectomy. An eye surgeon will drain the vitreous and replace the substance with saline. Doctors recommend this procedure in extreme circumstances since a vitrectomy may result in serious complications such as retinal detachments or early cataract formation.
Warning
If you notice that you suddenly have many new floaters in your vision, or if you have a black "curtain" that blocks out an area of your vision, this may indicate a retinal detachment. Contact an eye doctor immediately to reduce your risk for permanent vision loss. Do not rely on nutrients to repair a retinal detachment without first consulting with an eye doctor.
Considerations
Discuss your floaters with your eye doctor, particularly if your floaters disrupt your vision. Do not begin using magnesium supplements or other nutrients or herbs before discussing the potential benefits and risks with your doctor. Your doctor can help you determine if magnesium will interact with medications you take or if high dosages may cause complications with any health conditions you have.
