Most floaters are the result of bits of cells that remain in the vitreous humor after birth and float around when the vitreous becomes more liquified later in life.
Over 50% of people over 70 years of age report seeing floaters. Most floaters are age-related, due to degenerative changes of the vitreous humour or retina, resulting in the release of connnective tissue (protein) into the vitreous humour. Some parts of the vitreous may also form clumps or strands inside the eye.
Other spots can be caused by little bits of protein trapped within the eye during pregnancy. Trauma to the eye or breakdown of the vitreous humour may also cause spots and floaters. Many floaters remain in the eye for long periods of time before they gradually disappear.
Floaters are commonly found in nearsighted people and people with food allergies and candidiasis. Vitreous detachment is also common in diabetics, but the highest rate of complaints of floaters is in people over the age of 70. This is when the prevalence of a vitreous detachment jumps from 10% of the population to 63%.
From a Chinese Medicine perspective, floaters are an indication of congestion in the liver, kidney and colon. The herbs and nutrients we recommend below are chosen for their abilities to eliminate congestion in these organs in order to keep the vitreous of the eye clear from these annoying specks, as well as to help strengthen the retinal tissue and integrity of the blood vessels.
Finally, we believe chronic stress in one's life may also play a role in the generation of floaters, so having a daily routine of relaxation and meditation is very important.
IMPORTANT NOTE: A sudden increase of floaters can be an indication of a vitreous or retinal detachment. People who are very nearsighted and/or diabetic are particularly prone to floaters and retinal tears. If you suddenly see new floaters, make an appointment with your eye doctor immediately.
