<p>Noticing small dark spots, floating lines, cobweb-like shapes, or sudden flashes of light in your vision can be unsettling. These symptoms are often called <strong>eye floaters and flashes</strong>. While some floaters are harmless, new or sudden changes can sometimes signal a serious eye problem that needs urgent assessment.</p>
<p>If you live in Newmarket, Ontario, understanding what these symptoms may mean can help you decide what to do next. Moon Optik provides personalized eye care in Newmarket. However, if you suddenly develop new floaters or flashes, or notice a shadow across your vision, do not wait for a routine appointment. Seek urgent eye care immediately.</p>
<h2 id="what-are-eye-floaters">What Are Eye Floaters?</h2>
<p>Eye floaters are small shapes that appear to drift across your field of vision. They may look like:</p>
<ul>
<li>Tiny black or grey dots</li>
<li>Thin lines or squiggly threads</li>
<li>Small circles or rings</li>
<li>Cobweb-like shapes</li>
<li>Shadows that move when you move your eyes</li>
</ul>
<p>Floaters are often easiest to notice when looking at a bright, plain surface, such as a white wall or a clear sky. They usually move as your eyes move and may seem to drift away when you try to look directly at them.</p>
<p>Many floaters develop as the gel-like substance inside the eye changes with age. Long-standing floaters that remain stable may be harmless, but any new or sudden change should be assessed promptly.</p>
<h2 id="what-are-eye-flashes">What Are Flashes of Light?</h2>
<p>Eye flashes are brief bursts or streaks of light that appear even when there is no external light source. Some people describe them as lightning-like streaks, flickers, or tiny sparks near the edge of their vision.</p>
<p>Flashes can occur when the vitreous, the gel inside the eye, pulls on the retina. In some cases, this can be associated with a retinal tear or retinal detachment, which can threaten sight if not treated quickly.</p>
<p>Because it is not possible to determine the cause from symptoms alone, new flashes should be taken seriously.</p>
<h2 id="when-floaters-flashes-urgent">When Are Floaters and Flashes an Emergency?</h2>
<div class="mo-warning">
<p><strong>Seek urgent eye care immediately</strong> if you experience any of the following:</p>
<ul>
<li>Floaters that appear suddenly for the first time</li>
<li>A sudden increase in the number of floaters</li>
<li>New flashes of light, especially alongside floaters</li>
<li>A dark shadow, curtain, or veil moving across your vision</li>
<li>Sudden blurred vision or loss of part of your visual field</li>
<li>Floaters or flashes after an eye injury or eye surgery</li>
</ul>
<p>These symptoms can indicate a retinal tear or detachment. Contact an eye-care professional for immediate assessment or go to an emergency department if urgent eye assessment is not promptly available. Do not wait for a routine appointment.</p>
</div>
<p>Sudden loss of vision or severe eye pain requires emergency medical attention. If your vision is affected, do not drive yourself.</p>
<h2 id="common-causes-floaters">What Causes Eye Floaters and Flashes?</h2>
<h3>1. Age-related changes inside the eye</h3>
<p>The vitreous naturally changes as people get older. Tiny clumps or strands can cast shadows on the retina, creating floaters. These changes are common, but new symptoms still need assessment to rule out a retinal problem.</p>
<h3>2. Posterior vitreous detachment</h3>
<p>Posterior vitreous detachment occurs when the vitreous separates from the retina. It can cause floaters and flashes. Although this process is often not sight-threatening, it can sometimes be accompanied by a retinal tear, so an eye examination is important when symptoms begin.</p>
<h3>3. Retinal tear or retinal detachment</h3>
<p>A retinal tear can allow fluid to pass beneath the retina, causing it to separate from the back of the eye. Warning signs may include a sudden shower of floaters, flashes, a shadow, or reduced vision. This is a time-sensitive condition that needs urgent medical assessment.</p>
<h3>4. Eye injury or previous eye surgery</h3>
<p>Trauma and some eye procedures can be associated with changes inside the eye. If floaters or flashes develop after an injury or surgery, seek prompt professional advice rather than assuming they are normal.</p>
<h3>5. Other eye conditions</h3>
<p>Inflammation, bleeding inside the eye, and other eye conditions can also cause floaters. A qualified eye-care professional can assess the symptoms and determine whether further investigation or specialist treatment is needed.</p>
<h2 id="who-is-at-higher-risk">Who May Be at Higher Risk?</h2>
<p>Some factors can increase the likelihood of retinal problems or other causes of floaters and flashes, including:</p>
<ul>
<li>Older age and age-related changes inside the eye</li>
<li>Significant nearsightedness</li>
<li>A history of retinal tears or retinal detachment</li>
<li>Previous eye surgery, including cataract surgery</li>
<li>Eye injury or trauma</li>
<li>Some eye diseases, including conditions associated with bleeding or inflammation</li>
</ul>
<p>Having one or more risk factors does not mean you will develop a serious condition. However, it is important to tell your eye-care professional about your eye history and any recent changes in your vision.</p>
<h2 id="how-floaters-are-assessed">How Are Floaters and Flashes Assessed?</h2>
<p>An eye assessment may include questions about when the symptoms started, whether they are getting worse, whether one or both eyes are affected, and whether you have noticed changes in your vision.</p>
<p>Depending on your symptoms, the clinician may examine the back of your eye and recommend a dilated eye examination to check the retina. Dilating drops temporarily widen the pupils and may make your vision blurry or more sensitive to light for a few hours. You may need someone else to drive you afterward.</p>
<div class="mo-info">
<p><strong>Important:</strong> A routine vision check is not a substitute for urgent assessment of sudden floaters or flashes. If symptoms are new or worsening, explain this when seeking care so that the urgency is understood.</p>
</div>
<h2 id="can-floaters-go-away">Do Eye Floaters Go Away on Their Own?</h2>
<p>Some floaters become less noticeable over time as the brain adapts to them. If an eye examination confirms that the floaters are harmless, treatment may not be necessary.</p>
<p>Persistent floaters that interfere significantly with daily activities may occasionally require further discussion with an eye specialist. Treatments are not appropriate for everyone and can carry risks.</p>
<p>Do not assume that a new floater will disappear safely on its own. A sudden change should be assessed first, particularly if it occurs with flashes, blurred vision, or a shadow in your field of view.</p>
<h2 id="what-to-do-next">What Should You Do If You Notice Floaters or Flashes in Newmarket?</h2>
<ol>
<li><strong>Check whether the symptoms are new.</strong> A sudden onset or increase in floaters or flashes needs urgent assessment.</li>
<li><strong>Look for other warning signs.</strong> A curtain-like shadow, missing area of vision, or sudden blur makes the situation more urgent.</li>
<li><strong>Seek the right level of care.</strong> Do not wait for a routine appointment if symptoms have appeared suddenly. Use an urgent eye-care service or an emergency department if immediate assessment is needed.</li>
<li><strong>Share your eye history.</strong> Mention previous eye surgery, injuries, significant nearsightedness, retinal conditions, and when the symptoms began.</li>
<li><strong>Arrange routine follow-up when appropriate.</strong> If an urgent problem has been ruled out, follow the clinician's advice about monitoring and future eye examinations.</li>

<h2 id="faqs">Frequently Asked Questions</h2>
What do eye floaters look like?
Eye floaters may look like small dark dots, squiggly lines, rings, or cobwebs that drift across your vision. They are often more noticeable against a bright, plain background.
Are eye floaters always dangerous?
No. Many floaters are related to normal changes inside the eye and may become less noticeable over time. However, new floaters or a sudden increase in their number can signal a serious problem and should be assessed urgently.
Are flashes of light in the eyes serious?
They can be. Flashes may occur when the vitreous pulls on the retina, and sometimes this is associated with a retinal tear or detachment. New flashes, particularly with floaters or a shadow in your vision, require urgent assessment.
Should I book a regular eye exam for sudden floaters?
Do not wait for a routine eye exam if floaters have appeared suddenly, increased quickly, or occur with flashes, blurred vision, or a curtain-like shadow. Seek urgent eye care immediately.
Can eye floaters be treated?
Treatment depends on the cause. Harmless floaters often do not need treatment, while an underlying retinal tear or other eye condition may require urgent specialist care. A professional examination is needed to determine the cause.
