Why Do My Eyelashes Hurt? Causes and What to Do

Eyelashes themselves are unlikely to be the source of pain. What feels like a painful lash usually comes from the follicle, nearby skin, eyelid margin or eye surface. The pattern around the pain can help narrow the possibilities.

Match the pain to the likely cause

Several lash roots feel sore, itchy or crusty: blepharitis

Blepharitis is inflammation along the eyelid edge. It can cause sore or swollen lids, burning, grittiness, flakes at the roots of the lashes and crusting when you wake up. It may also make the eyes feel dry or watery. The National Eye Institute says common contributors include excess bacteria at the lash base and clogged or irritated eyelid oil glands (NEI).

This is a stronger possibility when tenderness is spread along the lash line rather than centered on one bump. Symptoms often come and go.

One spot or bump is painful: a stye

A stye is a tender red bump on or inside the eyelid. It commonly develops when bacteria infect an eyelash follicle or eyelid gland. A hard lump that is not very painful is more consistent with a chalazion, which is a blocked gland rather than an active stye (NHS).

Do not squeeze the bump or pull out the nearby lash. That can spread infection. See why a typical stye usually is not contagious and how hygiene still matters.

It scratches whenever you blink: a misdirected eyelash

A lash can turn inward and rub the eye, a condition called trichiasis. This tends to feel like something is stuck in the eye and may cause tearing, redness or pain with blinking. Repeated rubbing can scratch the cornea, so an eye-care professional should examine and manage a suspected misdirected lash (Cleveland Clinic). Do not repeatedly pluck it yourself; regrowth may continue in the same direction.

Pain began after mascara, lash glue, extensions or a lash lift: irritation or allergy

Stop using the new product. Lash-extension adhesive can trigger pain, itching, redness and swelling, while application can injure the eyelid or cornea. If you suspect an allergic reaction to extensions, do not try to remove or treat them yourself; the American Academy of Ophthalmology advises seeing an ophthalmologist promptly because improper removal can cause further injury (AAO).

The eye burns or feels gritty more than the lash line hurts: eye-surface irritation

Dry eye, an irritant or a small corneal scratch can feel as though the discomfort sits at the lashes, especially when blinking. This is less likely to cause a distinct sore spot at one follicle. If each blink hurts, use the broader pattern guide in Why Does My Eyelid Hurt When I Blink?.

What to do now

For mild tenderness without vision changes or significant eye pain:

• Stop eye makeup and lash products. If you wear contact lenses, remove them until the discomfort has settled or an eye-care professional has assessed it.
• Do not rub the eye, squeeze a bump or pull at lashes.
• If there is crusting along the lash line, hold a clean warm compress against the closed lid for 5 to 10 minutes, then gently wipe loosened debris from the lid edge. The NHS recommends regular gentle lid cleaning for blepharitis (NHS).
• If there is a small stye-like bump, use a clean warm compress for 5 to 10 minutes, two to four times daily (NHS).
• Arrange an eye exam if symptoms worsen, keep returning or do not improve, or if a lash appears to point toward the eye.

When eyelash pain needs prompt eye care

Seek same-day eye care for pain in the eye rather than mild lid tenderness, light sensitivity, blurred or changed vision, marked redness, pus, rapidly increasing swelling, or eye pain while wearing contact lenses. Contact-lens-related infection is a common cause of corneal inflammation, so do not put the lens back in while seeking advice.

Intense eye pain, a vision change, a very red and watery eye, an object stuck in the eye or significant trauma warrants urgent assessment (NEI). A stye also needs urgent advice if it becomes very painful or swollen, affects vision, produces pus or appears to spread beyond the original bump (NHS).
