According to experts floaters are usually nothing to worry about.據有關專家介紹飛蚊症通常是沒有什麼好擔心的問題。 More than 7 in 10 people experience floaters. 700多在10人的經驗，飛蚊症。 Now for some biology.現在一些生物學。
The lens in the front of your eye focuses light on the retina in the back of your eye.鏡頭前你的眼睛側重光對視網膜後面的你的眼睛。 The lens is like the one in a camera, and the retina is like film.鏡頭就像是一個在相機中，並在視網膜上的是一樣的電影。 The space between the lens and retina is filled with the "vitreous," a clear gel that helps to maintain the shape of the eye.之間的空間晶體和視網膜的，是充滿"玻璃體" ，一個清晰的凝膠，這樣有助於保持形狀的眼睛。
Floaters occur when the vitreous slowly shrinks over time.飛蚊症發生時，玻璃體慢慢萎縮，隨著時間的推移。 As the vitreous changes, it becomes stringy, and the strands can cast shadows on the retina.由於玻璃體的變化，它成為stringy ，並束能蒙上陰影視網膜。 These strands are the floaters.這些束是飛蚊症。 They can look like specks, filaments, rings, dots, cobwebs or other shapes.他們可以像斑點，細絲，戒指，圓點， cobwebs或其他形狀。 Floaters are the most vivid when you are looking at the sky or a white surface such as a ceiling.飛蚊症是最生動的時候，你是看天空或白色表面，如一個上限。 They move as your eyes move and seem to dart away when you try to look at them directly.他們提出，因為你的眼睛移動，而且似乎飛鏢遠離當你嘗試看看他們直接聯繫。
In most cases, floaters are just annoying.在大多數情況下，飛蚊症只是惱人。 When you discover them, they are very distracting.當你發現他們，他們是非常令人分心。 But, in time, they usually settle below the line of sight.但是，在當時，他們通常定居線以下的高地。 Most people who have visible floaters gradually develop the ability to make them "disappear" by ignoring them.多數人都看得見飛蚊症，逐步形成能力，使它們"消失" ，忽視這些問題。
When people reach middle age, the vitreous gel may pull away from the retina, causing "posterior vitreous detachment."當人們進入中老年，玻璃體凝膠，可拉離視網膜，造成了"玻璃體後脫離" 。 It is a common cause of floaters, and it is more likely in people who are diabetics, nearsighted, had eye surgery, or suffered inflammation inside the eye.這是一項共同的事業，無固定住所，它更可能在人，糖尿病患者，近視，眼外科手術，或因炎症裡面大有文章。
These vitreous detachments are often accompanied by light flashes.這些玻璃體分隊往往伴隨著光線閃爍。 The flashes can be a warning sign of a detached retina.閃光可以是一個警告標誌一種超脫的視網膜。 Flashes are also caused by head trauma that makes you "see stars."閃亮，也造成頭部外傷讓你"看明星" 。 Sometimes light flashes appear to be little lightning bolts or waves.有時光線閃爍似乎不大，閃電螺栓或波浪。 This type of flash is usually caused by a blood-vessel spasm in the brain, which is called a migraine.這種類型的閃光燈，通常是因血液血管痙攣，在大腦中，這是被稱為偏頭痛。 These flashes can happen without a headache and they are called an "ophthalmic migraine."這閃亮，可以發生在沒有一個令人頭痛的，他們所謂的"眼科偏頭痛" 。
If your floaters are just bothersome, eye doctors will tell you to ignore them.如果你的飛蚊症只是困擾，眼睛，醫生會告訴你不理會他們。 In rare cases, a bunch of floaters can hamper sight.在罕見的情況下，一群游離者可妨礙視線。 Then a "vitrectomy" may be necessary.那麼， "玻璃體切割術"可能是必要的。 A vitrectomy is a surgical procedure that removes the vitreous gel with its floaters. 1玻璃體切除術是一種外科手術，消除了玻璃體凝膠其飛蚊症。 A salt solution replaces the vitreous.鹽溶液代替了玻璃體。 The vitreous is mostly water, so patients who undergo the procedure don't notice a difference.玻璃體大多是水，所以曾接受程序不通知的差別。 However, this is a risky procedure, so most eye surgeons won't recommend it unless the floaters are a major impediment.但是，這是一個冒險的程序，使大多數眼科外科醫生不會推薦，除非飛蚊症，是一個主要的障礙。
