You’re reading a book or looking out at a bright sky, and something drifts across your vision. It looks like a tiny thread, a smudge, or maybe a little web floating just out of reach. No matter where you look, it moves with your eyes. If this sounds familiar, you’re not alone.
Most eye floaters are harmless and a natural part of how the eye changes over time, but some floaters can signal something that needs prompt attention from an optometrist in Whitehorse. Knowing the difference can help you take the right next step for your eye health.
What Eye Floaters Actually Are
Your eye is filled with a clear, gel-like substance called vitreous. Tiny fibres inside this gel can clump together over time, and those clumps cast small shadows on your retina, which is the light-sensitive layer at the back of your eye. Those shadows are what you see as floaters.
Floaters show up most clearly when you’re looking at something bright, like a white wall, a sunny window, or an open sky. They tend to drift slowly and shift when your eyes move, which is why they feel like they’re following your gaze.
Common Causes
The Aging Connection
As the body ages, the vitreous gel inside the eye gradually shrinks and becomes more liquid. This is a normal process that happens to most people, and floaters tend to become more noticeable through your 50s and 60s. That said, they can appear at any age.
Head impacts or physical trauma can also cause the vitreous to shift earlier in life, which is why floaters aren’t always tied to age. If you’ve had a head injury and noticed changes in your vision afterward, that’s worth mentioning during your next eye exam.
When Floaters Come with Flashes
Sometimes the vitreous gel pulls away from the retina as it shrinks. This is called a posterior vitreous detachment (PVD), and it can cause brief flashes of light along with new floaters. These flashes occur because of the physical tugging on the retina as the gel separates.
While this type of event is fairly common, it is important to take it seriously. You should see an optometrist promptly for an eye exam. This is the only way to rule out more serious concerns, such as a retinal tear or detachment, which can occur if the gel pulls too hard on the retina during the separation process.
Different Types of Floaters
Occasional Translucent Spots
Occasional translucent spots are the most common type. They tend to come and go, don’t cause any other symptoms, and are often just a background part of your vision you’ve learned to tune out. While they’re generally harmless, it’s still worth having an optometrist take a look to confirm everything is healthy underneath.
Cobweb, Cloud-Like, or Dense Dark Spots
These floaters tend to appear more suddenly and can look like a cluster of dark shapes or a filmy haze. They’re often a sign that part of the vitreous is separating from the back of the eye. This doesn’t always mean something is wrong, but it does mean the retina needs to be evaluated.
Whether your floaters are subtle or more dramatic, all types are worth having reviewed by your optometrist to confirm the retina hasn’t been affected in the process.
Signs That Call for a Same-Day Eye Exam
Most floaters are gradual and predictable. However, certain changes in your vision call for a same-day appointment, not something to wait on. Pay attention if you notice:
- A sudden onset of many new floaters appearing at once
- Flashes of light alongside new floaters
- A dark curtain or shadow blocking part of your vision that doesn’t go away
These symptoms can point to a retinal tear or detachment, which needs to be addressed promptly. Getting your eyes checked quickly in these situations can help protect your long-term vision.
What to Expect at Your Eye Exam for Floaters
When you come in for floater-related concerns, the eye doctor will typically perform a dilated eye exam. This involves applying medicated drops to widen your pupils, which gives the optometrist a clear, full view of your retina. We can then check for tears, detachment, or any bleeding at the back of the eye. In some cases, optical coherence tomography (OCT) imaging may also be used to get a more detailed look at the retinal layers.
The drops can temporarily blur your close-up vision and make your eyes more sensitive to light for a few hours, so it’s a good idea to bring sunglasses and arrange a ride if possible.
Regular Exams Help Keep You Ahead of Changes
Floaters that come and go are often monitored over time rather than treated right away. Your optometrist can establish a baseline and check back in at follow-up appointments to watch for any changes. This kind of ongoing care can help catch anything new before it becomes a bigger concern.
