If you see yellow spots it could mean that there is bleeding or an injury to the light-sensitive tissue at the back of your eye. If this is the case it may be a sign of damage to your retina and should be checked by an eye doctor immediately. If the bleeding is small it will probably disappear on its own, but if you have other symptoms such as blurred vision or flashes of light then you should get medical attention straight away.
The yellow spots you are seeing may also be a symptom of a condition known as macular degeneration. This is a common condition that causes people to lose their central vision. It can be caused by a number of different factors such as ageing, head injuries, diabetes or infection. If you have a family history of the condition then you are more likely to develop it.
Another possible cause of yellow spots is a condition called xanthopsia. This is a benign yellow tumor that can appear on the surface of your eye. It can be a side effect of certain medications that are used to treat heart conditions such as digoxin and ivabradine.
Finally, if you are seeing yellow spots that move around your field of vision it can be a sign that your ancestors are watching over you. This is because the color yellow has long been associated with divinity, holiness and resurrection. It can also symbolize protection from light and eyestrain.
