The Causes and Effects of Floaters
The cause of eye floaters is a protein known as collagen. The back of the eye contains a gel-like substance known as vitreous humor. As a person ages fibers decrease in size and collect in this area among the vitreous. The changes that take place cause the spots or floaters. Floaters can occur in all ages, but is most prominent between the ages of 50-75. It also affects people who have undergone cataract surgery or those who are nearsighted, as well as other disorders that occur within the eye

Treatment for Floaters
There is no real treatment for eye floaters, as it is not necessary. Most people become used to them. For some people treatment is necessary, as it impairs their ability to see. This surgery is generally done by removing the vitreous. This surgery does carry the risk of retinal bleeding or tearing though. Laser surgery is also an option to break up the floaters.

Macular Degeneration

Macular degeneration, also known as age-related macular degeneration (AMD), is caused by deterioration of the retina and can severely impair vision. There is no cure for macular degeneration, but it can be treated with vitamins, laser therapy, medications, and vision aids.

Tips for Protecting Eye Health and Preventing Macular Degeneration

Maintain a healthy weight.
Eat a nutritious diet that includes green leafy vegetables, yellow and orange fruit, fish and whole grains.
Don't smoke.
Maintain normal blood pressure and control other medical conditions.
Exercise regularly.
Wear sunglasses and hats when you are outdoors.
Get regular eye exams, and consult your doctor if you notice vision changes.

Risk Factors for Age-Related Macular Degeneration

Age
The number one risk factor is age. One-third of adults over 75 are affected by AMD.

Smoking
Smoking increases a person’s chances of developing AMD by two to five fold. Because the retina has a high rate of oxygen consumption, anything that affects oxygen delivery to the retina may affect vision. Smoking causes oxidative damage, which may contribute to the development and progression of this disease.

Learn more about why smoking damages the retina, and explore a number of steps you can take to protect your vision.

Family History of AMD
A person is more likely to develop AMD if someone in his or her immediate family has had it.

Gender
Females are more likely to develop AMD than males. This factor may be because females live longer than males, and thus have more time to develop the disease.

Race
Caucasians are more likely to develop AMD than other races. This factor may be related to differences in genetic background or pigmentation.

Prolonged Sun Exposure
Although the evidence is not conclusive, some studies suggest an association between AMD and cumulative eye damage from ultraviolet (UV) and other light. This light may damage the retina and increase the risk of AMD.

Explore the latest research regarding bright lights and retina damage, and how to properly protect your eyes.

Diet
People with diets that are elevated in fat, cholesterol and high glycemic index foods, and low in antioxidants and green leafy vegetables may be more likely to develop AMD. High-glycemic index foods, such as white rice, bread and pasta raise blood sugar rapidly, whereas low-glycemic foods, such as whole grain breads or oatmeal can lower the risk of AMD by stabilizing blood sugar levels.

https://www.brightfocus.org/macular/article/top-foods-eye-health

Obesity
A person with a BMI (body mass index, a measure of body fat) of greater than 30 is 2.5 times more likely to develop the disease than a person with a lower BMI.

High Blood Pressure

High blood pressure, like smoking, leads to a constriction (narrowing) of the blood vessels that nourish the retina, restricting oxygen flow.

Eye Color
People with light-colored eyes are more likely to develop the dry type of AMD. This factor may be because light-pigmented eyes offer less protection from damaging UV light.

Inactivity
In dry AMD, the retina does not receive adequate oxygen, leading to the death of cells in the macula. Exercise improves cardiovascular health and might help prevent AMD.

Presence of AMD in One Eye
If a person has AMD in one eye, he or she is more likely to develop it in the other eye.

Heredity and Age-Related Macular Degeneration
Age-related macular degeneration typically affects people over 50. Scientific evidence shows that genes may play a role in the development of nearly three out of four cases of this devastating eye disease.

Medical experts have found several genes that are strongly associated with the risk of developing macular degeneration. Researchers continue to study other gene candidates to determine their role in this disease.

Although macular degeneration definitely has a strong genetic component, its development is mostly due to a combination of factors, including:

Gene mutations or variations
Environmental factors such as:
Diet
Smoking
Exercise

Thanks, Barb, for all the wonderful eye-health information. 

One of the doctors who hosts websites, such as Mercola, etc., has posted more than once about research showing a strong correlation with Macular Degeneration and having taken aspirin on a regular basis.

The research did not mean that taking aspirin for the occasional headache will cause M.Degen., but for those on long-term, daily-use aspirin, for supposedly preventing heart attacks, it is a serious risk.  Not sure if the connection between taking long-term aspirin and macular degeneration applies to both forms of the disease, the "wet" form and the "dry" form, but it's either one or both.  Possibly I can find the research and post here.

Here, from JAMA, Journal of the American Medical Association:

Full Text

In their prospective population-based cohort study of 2389 patients in the Blue Mountains region in Australia, Liew and colleagues1 report on the association of long-term use of low-dose aspirin and age-related macular degeneration (AMD), the leading cause of blindness in Western countries. The principal finding is that regular aspirin use is associated with an approximately 2.5-fold greater risk of incident AMD. This relationship is specific for late neovascular (wet) AMD but not geographic atrophy (dry AMD) and is independent of potential confounders, such as cardiovascular disease, smoking, age, sex, systolic blood pressure, and body mass index.

What a much-needed topic Barb.  I would only add astaxanthin to your list of mixed carotenes.  It's in a product called "Macuguard" and others.

ilinda, wow, thanks for posting that! I had no idea, the connection between regular aspirin dose and macular degeneration.
I suppose once the word gets around on that, some people will go off the regular dose aspirin.
Good idea to keep it around though (a full dose aspirin). It does increase the chances of survival in an actual heart attack.
I no longer take aspirin because I cannot take it with one of my medicines.
