BOTOX® rarely affects vision. Because it’s often injected near the eyes, some people experience temporary eye-related side effects, such as dry or irritated eyes, light sensitivity, mild eyelid swelling, or a drooping eyelid that can make vision feel slightly blurry. These effects usually fade as BOTOX® wears off. Sudden double vision or blurred vision, especially with trouble swallowing, speaking, or breathing, needs immediate medical attention.
Key Takeaways
- Eye-related side effects after cosmetic BOTOX® are uncommon and almost always temporary.
- Possible effects include dry eyes, eye irritation, light sensitivity, eyelid swelling, and a drooping eyelid or brow.
- A drooping eyelid can partly block your vision or make it feel blurry, but it usually improves over a few weeks.
- Avoid driving if your vision is blurred or your eyelids droop, and contact your provider.
- Double vision or blurred vision with trouble swallowing, speaking, or breathing requires emergency care.

How BOTOX® Can Affect Your Eyes
BOTOX® Cosmetic is approved to soften frown lines between the brows, crow’s feet at the outer corners of the eyes, and forehead lines. All of these areas are close to the muscles that control your eyelids and blinking.
When BOTOX® is placed correctly, it relaxes only the targeted muscles. Occasionally, it affects nearby muscles or the tear film, which can cause temporary eye-related side effects.
Most eye-related side effects of BOTOX® are temporary. Know which symptoms need emergency care.
Dry Eyes, Irritation, and Light Sensitivity
The FDA prescribing information for BOTOX® Cosmetic notes reports of dry eye after injections in or near the muscle that surrounds the eye. Symptoms can include eye irritation, sensitivity to light, or changes in vision.
If these symptoms persist, the FDA labeling advises providers to consider a referral to an ophthalmologist.
Drooping Eyelid (Ptosis)
A drooping upper eyelid is the best-known eye-related side effect. According to the FDA prescribing information, eyelid drooping occurred in 3% of patients treated for frown lines in clinical studies. Brow drooping occurred in 2% of patients treated for forehead lines.
A drooping eyelid can partially cover your field of vision or make your eyes feel tired or heavy. Cleveland Clinic notes that drooping is almost always related to injection placement, not something the patient did, and that it’s temporary.
Eyelid Swelling
Mild swelling around the eyes can occur, especially after crow’s feet treatment. The FDA prescribing information lists eyelid swelling as the most common side effect of crow’s feet treatment, reported in 1% of patients. It usually settles within days.
Blurred or Double Vision
Blurred or double vision is rare after cosmetic BOTOX®. It’s one of the symptoms listed in the FDA’s boxed warning about the toxin’s effect spreading beyond the injection site. Because it can signal a more serious problem, any new double vision or significantly blurred vision should be checked promptly. Seek emergency care if it comes with trouble swallowing, speaking, or breathing.
How Long Do Eye Side Effects Last?
Because BOTOX® is temporary, its side effects are temporary too. Cleveland Clinic explains that once the effect wears off, muscles return to their normal function.
- Dry eyes and irritation often improve within days to weeks.
- Eyelid swelling usually settles within a few days.
- A drooping eyelid or brow typically improves gradually over several weeks as the BOTOX® effect fades.
There’s no evidence that properly administered cosmetic BOTOX® causes permanent damage to your eyesight. Still, any vision change deserves a call to your provider.
Who Should Be Extra Cautious?
Tell your injector before treatment if you have:
- Dry eye disease or chronic eye irritation
- Recent eye or eyelid surgery
- A history of a drooping eyelid
- Any condition affecting the nerves or muscles, such as myasthenia gravis
- A previous side effect after BOTOX® or another neuromodulator
Your injector may adjust your dose or injection points, or recommend checking with your eye doctor first.
How to Lower Your Risk
Choose an experienced injector. Precise placement is the most important factor in avoiding eye-related side effects. An injector who knows facial anatomy places BOTOX® at the right depth and a safe distance from the muscles that control your eyelids. The right dose matters too. Our guide to how many BOTOX® units are used for different areas of the face explains typical dosing.
Share your full health history, including eye conditions and medications.
Follow aftercare instructions. Stay upright for about four hours and don’t rub or massage treated areas for the first day, especially around the eyes. Read our BOTOX® aftercare guide for the full list.
What to Do If Your Vision Changes After BOTOX®
Contact your provider. Describe what you’re noticing and when it started. Your provider can evaluate whether it’s dry eye, swelling, or eyelid drooping, and recommend next steps.
Avoid driving if your vision is affected. The FDA labeling advises patients to avoid driving or other potentially hazardous activities if they experience blurred vision or drooping eyelids.
Ask about treatment options. For a drooping eyelid, providers may prescribe special eye drops that can temporarily help lift the lid while the BOTOX® wears off, as described in a clinical review of neuromodulator complications. For dry eyes, your provider may recommend lubricating drops or a visit to your eye doctor.
Get emergency care for serious symptoms. Seek medical care immediately if vision changes come with trouble swallowing, speaking, or breathing, or with muscle weakness beyond the treated area.
Frequently Asked Questions
Can BOTOX® cause blurry vision?
It’s uncommon, but it can happen. Blurry vision is usually related to dry eyes or a drooping eyelid and improves over time. Sudden or significant blurred vision, especially with other symptoms like trouble swallowing, needs prompt medical attention.
Can BOTOX® around the eyes damage your eyesight?
There’s no evidence that properly administered cosmetic BOTOX® causes permanent eye damage. Most eye-related side effects are temporary and fade as the BOTOX® wears off.
How long does a droopy eyelid from BOTOX® last?
A droopy eyelid usually improves gradually over several weeks. Your provider can assess it and may recommend prescription eye drops to help in the meantime.
Can BOTOX® cause dry eyes?
Yes. The FDA prescribing information notes reports of dry eye after BOTOX® Cosmetic injections near the eyes. Let your provider know if you have ongoing dryness, irritation, or light sensitivity.

Yes, for most people. You can drive yourself home after treatment. If you ever notice blurred vision or a drooping eyelid afterward, avoid driving until your vision is clear and contact your provider.
Can BOTOX® make your eyes swell?
