Needs evaluation.: Black spots and lines in your vision need evaluation by an opthalmologist as they may indicate problems with your retina and could lead to blindness. If these have been present for a while there is no urgency, but if these just showed up you should be seen as soon as reasonably possible.

Three options: You need a dilated eye exam to establish that it is only floaters that are the cause of your concern. Some floaters are normal. If exam is normal, then you can live with floaters safely. If you just can't, some might consider laser, others vitrectomy. Remember, however, there are risks with every surgical procedure. Laser is sometimes not effective and vitrectomy causes cataracts. See a doc.

Floaters: A posterior vitreous detachment causes floaters. This is a situation where the vitreous(jelly) of the eye detaches (not a retinal detachment), it then "crumples" up leaving dots, spots, strands of blurry vitreous; i.e. The "floater". You should have an exam to ensure the incident did not tear the retina, which could lead to a retinal detachment. Wait one year then consider surgery.
