Right this may seem a stupid idea to many but im studying to be an optometrist who should be your first port of call if you notice or develop anything unusual to do with your eyes. To help me with my studies please fire away any questions you have concerning your eyes, basically this is designed for me to reinforce my knowledge on the complicated subject of optics.
EG:
Q: What are those little black dots i keep seeing floating around? Is there anything wrong with me?
A: This is a natural occurence called "floaters", most adults have them and some more than others. It occurs when the jellatinous substance inside of your cornea liquifies over time and debree breaks loose and floats around (hence terminology "floaters"). If you notice these floaters increasing in great amounts, especially to the point where it is affecting your vision, go and see your optometrist.
PS: One last thing, i am not yet a qualified optometrist, although i have utmost faith in my knowledge on quite a lot of things to do with eyes please dont take my word for anything, also if something seems a genuine problem go and see your optometrist.
