Ever noticed a red spot in your eye and contemplated how it got there? Burst capillaries, though harmless, can look alarming and happen for reasons you may not expect. From rubbing your eyes too hard to straining during a workout, small actions can weaken those tiny vessels. Even screen time or an old pair of contacts could be the culprit—and sometimes, it’s your body signaling something deeper. Let’s analyze what really causes this.
Vigorous Eye Rubbing and Irritation
Vigorous eye rubbing might seem harmless, but it’s one of the quickest ways to burst those tiny capillaries in your eyes. Whenever you rub too hard, you increase pressure inside your eye, which can snap those delicate blood vessels.
Eye irritation from allergies, dust, or dryness often triggers the urge to rub, but giving in only makes things worse. Over time, repeated vigorous rubbing weakens the vessel walls, making them more likely to break even with minor pressure.
In case you’re staring at screens or reading for hours, strain can make your eyes feel tired, tempting you to rub them—resist! Instead, try a cold compress or artificial tears to soothe irritation without risking capillary breakage. Your eyes will thank you.
Improper Contact Lens Use
Should you not clean your contact lenses properly, bacteria and debris can build up, irritating your eyes and making capillaries more likely to burst.
Wearing lenses too long reduces oxygen to your cornea, putting extra stress on delicate blood vessels.
Rough handling during insertion or removal can also cause tiny injuries that lead to ruptured capillaries.
Poor Lens Hygiene
Poor lens hygiene is one of the most common—and avoidable—causes of burst eye capillaries, especially since you wear contacts.
Should you not clean your lenses properly, proteins and debris build up, irritating your eyes and increasing the risk of broken blood vessels. Using old or dirty contacts introduces bacteria, which can damage delicate eye tissue.
Storing lenses in water instead of saline solution or skipping regular cleaning weakens their safety, making your eyes more vulnerable.
Even rubbing your eyes while wearing contacts can put too much pressure on capillaries, causing them to rupture. To avoid this, stick to a strict cleaning routine, replace lenses as recommended, and never skip disinfecting them.
Your eyes deserve the care—don’t let poor lens hygiene put them at risk.
Extended Wear Risks
While extended wear contacts might seem convenient, they come with risks should they not be used correctly. Keeping them in too long can starve your cornea of oxygen, leading to irritation and even broken blood vessels like a subconjunctival hemorrhage.
Skipping proper cleaning lets bacteria and protein buildup irritate your eyes, making capillaries more likely to burst. Should you leave them in past the recommended time, dryness kicks in, tempting you to rub your eyes—another fast track to popped vessels.
Stick to your lens schedule, clean them thoroughly, and give your eyes breaks to breathe. Ignoring these steps ramps up risks—so in case your eyes feel dry or strained, take those lenses out. Your eyes will thank you.
Incorrect Insertion Techniques
Putting in contact lenses the wrong way doesn’t just make them uncomfortable—it can actually damage your eyes. Whenever you mishandle them, the extra pressure or friction can burst tiny blood vessels, leaving red streaks.
Here’s how improper insertion causes trouble:
- Dirty hands or dry lenses—Debris or dryness creates friction, irritating your eyes and straining blood vessels.
- Wrong orientation—Inserting a lens inside-out presses unevenly, increasing pressure on delicate capillaries.
- Overhandling—Poking or adjusting too much stresses the eye’s surface, raising rupture risks.
- Expired or damaged lenses—Worn-out edges scratch your eye, prompting rubbing that weakens vessels.
Always wash your hands, check lens condition, and follow proper steps to avoid unnecessary strain.
Your eyes deserve gentle care—skip the shortcuts to keep them clear and healthy.
Prolonged Screen Time and Eye Strain
Staring at screens for too long can tire your eyes, making them dry and irritated, which could lead to burst capillaries.
The blue light from devices adds to the strain, putting extra pressure on those tiny blood vessels.
But you can protect your eyes by adjusting screen settings, taking breaks, and using proper lighting to ease the stress.
Digital Eye Strain Effects
Since many of us spend hours glued to screens, digital eye strain can sneak up without indication, leaving your eyes feeling gritty, tired, and sore.
This strain can weaken tiny blood vessels due to constant focus and dryness, making them more prone to bursting. A subconjunctival hemorrhage often occurs at the moment these vessels rupture, leaving a bright red patch on your eye.
Here’s how digital eye strain affects you:
- Blurred vision – Staring at screens reduces blinking, drying out your eyes.
- Headaches – Squinting or poor lighting strains your eye muscles.
- Eye fatigue – Prolonged focus without breaks tires your eyes.
- Redness – Rubbing irritated eyes can burst capillaries.
To ease strain, follow the 20-20-20 rule and adjust screen settings.
Your eyes will thank you!
Blue Light Exposure Risks
Ever question why your eyes feel fried after hours of screen time? Blame blue light—the high-energy glow from your devices that can tire your eyes fast. Digital eye strain isn’t just about dryness; it’s your retinas working overtime. Overexposure could even mess with sleep or harm delicate eye cells over time.
| Blue Light Effects | Why It Matters |
|---|---|
| Disrupts sleep | Throws off your body’s natural rhythm |
| Strains retinas | Can lead to long-term wear and tear |
| Triggers dryness | Makes blink less, eyes feel gritty |
You’re not alone—59% of adults battle this daily. The fix? Less screen time and the 20-20-20 rule: peek away every 20 minutes to save those strained peepers. Your eyes will thank you.
Prevention and Relief Tips
Blue light isn’t the only thing straining your eyes—long hours glued to screens can leave them red, dry, and even cause tiny blood vessels to burst.
Prevention starts with simple eye care habits to keep your peepers comfortable and healthy. Here’s how to ease the strain:
- Follow the 20-20-20 rule: Every 20 minutes, look at something 20 feet away for 20 seconds to give your eyes a break.
- Adjust your screen: Match brightness and contrast to your surroundings to reduce glare and discomfort.
- Use artificial tears: Lubricating drops soothe dryness and irritation, helping prevent capillary damage.
- Mind your posture: Sit an arm’s length from the screen, with it at eye level to avoid extra strain.
Small changes make a big difference in protecting your eyes.
Injuries or Trauma to the Eye
In case you’ve ever taken a hit to the eye—whether from an accidental bump or a sports injury—you could have noticed red splotches afterward. These are often subconjunctival hemorrhages, where tiny blood vessels burst under the clear surface of your eye.
Injuries and eye trauma, like being struck by a ball or rubbing too hard, can easily cause this. Even minor scratches from dust or debris irritate the eye, leading to inflammation and broken capillaries. Surgical procedures near the eye could also disrupt these delicate vessels.
And in the event you’ve had a head injury, the pressure changes can make capillaries in your eye more likely to rupture. While it looks alarming, it’s usually harmless—just your eye’s way of healing after trauma.
Underlying Health Conditions
While injuries can cause those alarming red spots in your eye, sometimes the reason isn’t something you can see or feel right away.
Hidden health conditions can weaken or damage your eye’s tiny blood vessels, making them more likely to burst.
Here’s what could be happening beneath the surface:
- High blood pressure – Strains blood vessel walls, increasing rupture risk.
- Diabetes – Damages small blood vessels over time, making them fragile.
- Blood clotting issues – Conditions like hemophilia or blood thinners prevent proper clot formation.
- Aging – Thinner, looser tissues can’t support capillaries as well.
If you notice frequent bursts, it’s worth checking in with your doctor.
These aren’t always serious, but they can hint at something deeper needing attention.

Physical Strain and Increased Pressure
Even in the event that you haven’t taken a punch to the face, something as simple as lifting a heavy box or coughing hard can leave your eye looking like it’s been through a battle.
Physical strain—whether from weightlifting, intense workouts, or even a sneezing fit—can create increased pressure in your head. That sudden spike forces blood vessels in your eye to stretch beyond their limit, leading to burst capillaries.
Holding your breath during exertion, like whenever you’re straining to move furniture, makes it worse. Even bending forward sharply can push pressure into delicate eye vessels.
To reduce risk, ease into heavy tasks, breathe steadily, and avoid overexertion.
While it looks alarming, these tiny ruptures usually heal on their own. Just give your body time—and perhaps skip the heroics next time you’re moving couches.
