Floaters are small specks or clouds moving in your field of vision, and are most commonly seen when you look at a blank wall or a clear blue sky. The floaters may drift about when you move your eyes.
In most cases, floaters are part of the natural aging process. Floaters look like cobwebs, squiggly lines, or floating bugs. While the objects appear to be in front of the eye, they are actually floating inside of the eye itself. As we get older, the vitreous (the clear, gel-like substance that fills the inside of the eye) tends to shrink slightly and detach from the retina (posterior vitreous detachment), forming clumps within the eye. What you see are the shadows these clumps cast on the retina, the light-sensitive nerve layer lining the back of the eye. Your brain usually learns to ignore the floaters over 4-6 weeks. If you continue to be hindered by the floaters, you can consider Laser Floater Removal.
The appearance of flashing lights comes from the traction of the vitreous gel on the retina at the time of vitreous separation. Flashes look like twinkles or lightning streaks. You may have experienced the same sensation if you were ever hit in the eye and “saw stars.”
Floaters and flashes are sometimes associated with retinal tears. When the vitreous shrinks, it can pull on the retina and cause a tear. A torn retina is a serious problem. It can lead to a retinal detachment and blindness. You should see an eye doctor immediately if:
These may be symptoms of a retinal tear or detachment.

"Dr. Rhodes is a master at getting your vision right. I love not wearing glasses; colors are brighter, vision is clearer. He explains what is going on with your vision and what he is going to do for you in a manner that is clear and understandable. Also, it's a small thing, but increasingly rare, every time I have an appointment, I am seen within a few minutes of the appointed time. I recommend Dr. Rhodes to everyone I know, he is just that good!"

"I am very impressed during my first visit with Dr. Dang, from the front desk to the nurses, gave me a good feeling who Dr.Dang is. Dr. Dang is an excellent doctor, very thorough, approachable, kind and polite. It didn't give me a second thought to go ahead with my cataract surgery. I am extremely happy with him and his team during my surgery. I'm blessed I found an excellent doctor like him and proud to recommend to anyone."
