Blinking is something we do constantly without thinking. But when it starts to hurt, it can quickly become distracting, frustrating, and even concerning. Eye discomfort while blinking can have many causes, from temporary irritation to signs of a more persistent eye condition.
Some of the most common causes are dry eye, conjunctivitis (pink eye), and digital eye strain. Whether your symptoms feel like stinging, dryness, pressure, or sensitivity, it’s important to understand what could be going on.
What Could Be Causing Eye Discomfort When You Blink?
If blinking causes discomfort, it may be your eye’s way of signaling that something isn’t working quite correctly, whether it’s related to tear quality, inflammation, or eye pressure.
Conjunctivitis (Pink Eye)
Conjunctivitis, or pink eye, is inflammation of the conjunctiva, the thin layer that lines the white part of your eye and inner eyelids. It’s often triggered by a viral or bacterial infection, but allergens and irritants can also cause it.
Common symptoms include:
- Redness and itchiness
- A gritty or burning sensation
- Watery or thick discharge
- Eyelid swelling or sensitivity when blinking
Depending on the cause, treatment might include prescription antibiotics or antiviral eye drops, or allergy medications to relieve symptoms. An optometrist can diagnose the type of conjunctivitis and recommend the right approach.
Digital Eye Strain
Reduced blinking during screen use can cause tears to evaporate more quickly, which may lead to dry eye or worsen existing symptoms. This is commonly known as computer vision syndrome or digital eye strain.
Symptoms may include:
- Eye fatigue
- Burning or dryness
- Blinking that feels strained or uncomfortable
- Headaches or blurred vision
To ease symptoms, follow the 20-20-20 rule (every 20 minutes, look at something 20 feet away for 20 seconds), reduce glare with screen filters, and adjust your monitor height. An optometrist may also recommend blue light filtering lenses or artificial tears to improve comfort during screen use.
Dry Eye
Dry eye is one of the leading causes of blinking discomfort. It occurs when your eyes don’t produce enough tears or when those tears evaporate too quickly. This can lead to inflammation and friction with every blink, making your eyes feel irritated or gritty.
You may notice:
- Burning or stinging
- Grittiness or a foreign body sensation
- Redness or excess tearing
- Blurred vision that improves after blinking
Dry eye can be caused by screen time, contact lens wear, aging, or environmental factors like wind and dry air. It can also be linked to health conditions or medications. If you’re experiencing signs of dry eye, taking a dry eye assessment can help identify what’s causing your symptoms and which treatment options may be suitable for you.
Treatments for dry eye can include:
- Lubricating eye drops or artificial tears
- In-office heat-based therapies to unclog oil glands
- Intense pulsed light (IPL) therapy to treat inflammation around the eyelids and meibomian glands
- Radiofrequency (RF) heats up the meibomian glands to promote tissue remodeling, increased blood circulation, and detoxification
- Low-level light therapy (LLLT) to support tear film balance and stimulate cellular repair
- Thermal gland expression (such as LipiFlow) to help clear blockages in the oil-producing glands of the eyelids
A personalised treatment plan can help restore comfort and protect the surface of your eye from ongoing dryness.
When Should You See an Optometrist?
While some eye discomfort may go away on its own, persistent symptoms should never be ignored. If blinking continues to cause pain or irritation, an optometrist can perform a comprehensive eye exam to uncover the root cause.
Book an appointment if you’re experiencing:
- Discomfort that lasts more than a day or 2
- Eye pain or sensitivity to light
- Redness, swelling, or discharge
- Blurry vision or eye strain
- Recurring dryness or burning
Depending on your symptoms, treatment may include prescription eye drops, visual aids, or targeted in-office therapies designed to improve comfort and visual clarity. Getting the right care early can help you avoid complications and feel better, faster.
