I am happy to help you today.
The flashes of light and floaters you mentioned are classical signs of a vitreous detachment. The vitreous is a jelly like substance that fills the majority of the eye. At some point in life it will detach from the retina as a normal process called a posterior vitreous detachment or PVD.
A PVD is almost always accompanied by a new floater and flashes of light. The flashes arise when the vitreous tugs or pulls on the retina.
A PVD, though it is a normal process, must be evaluated by an optometrist or ophthalmologist because when the vitreous pulls away from the retina sometimes it will pull retina with it.
If retinal is broken in the PVD process it may cause a much more serious condition called retinal detachment.
Retinal detachment needs to be treated quickly if it happens.
Your eye doctor will perform some tests including a dilated fundus examination to determine if the retina is intact.
Symptoms of a retinal detachment which you should watch for and seek help immediately if they arise include a sudden increase in floaters, missing chunks of your vision, a curtain-like effect being drawn over the vision, or any other loss of vision.
I suggest you obtain an examination on Tuesday after the holiday if you do not notice any other problems. If any of the retinal detachment signs arise I suggest a trip to the ER.
I will stay on for a few minutes to answer any other follow-up questions. Please don't forget to offer a positive rating once your question has been answered fully.
