Why this topic matters
- October is Breast Cancer Awareness Month, and many people associate it with mammograms, education, and support. But fewer realize that breast cancer treatments can sometimes affect the eyes and vision.
- As an eyecare provider, Clara Vista Eyecare is uniquely positioned to inform patients about ocular side effects, early warning signs, and how to maintain eye health during cancer treatment.
- This kind of post can build trust, provide a public service, and tie into your practice’s broader mission of comprehensive eye care.
When Breast Cancer Meets Eye Health — What Patients Should Know
Introduction
October is Breast Cancer Awareness Month—a time to spotlight prevention, support, and survival. At Clara Vista Eyecare, we also want to raise awareness about a less‑talked‑about subject: how breast cancer and its treatments can affect the eyes and vision. Whether you are a patient, caregiver, or simply curious, here’s what you should know.
How Breast Cancer Treatments Can Affect the Eyes
While eye side effects are relatively uncommon, they do occur. It’s important for anyone undergoing breast cancer treatment to be aware. Some possible effects include:
- Dry, itchy, red, or irritated eyes Breastcancer.org+2American Academy of Ophthalmology+2
- Excess tearing (epiphora) or blockage of tear drainage channels (e.g. canalicular stenosis) American Academy of Ophthalmology+2PubMed+2
- Blurred or double vision Breastcancer.org+2Dana-Farber Cancer Institute+2
- Deposits or changes in the retina or macula (especially with certain hormone therapies) PubMed+2Family Vision Center+2
- Optical nerve changes, cataract risk, or changes in internal ocular structures Cockrell Eyecare Center+3PubMed+3American Academy of Ophthalmology+3
- In rare cases, metastatic breast cancer may spread to ocular tissues (the eye or surrounding structures) Dana-Farber Cancer Institute+2Cockrell Eyecare Center+2
Because cancer can metastasize to distant organs via the bloodstream, the choroid of the eye is one known site for metastatic lesions, and breast cancer is often cited as one of the more common primary tumors to do so. Breastcancer.org+3NeuroVisual Specialists+3Dana-Farber Cancer Institute+3
In a review focused on early‑stage breast cancer therapies, some treatments (especially taxane chemotherapy) were associated with irritation of the ocular surface and tear drainage issues, while tamoxifen (a hormone therapy) has been linked to retinal or optic nerve changes over time. PubMed
What Patients & Caregivers Should Watch For
If you or a loved one is undergoing breast cancer treatment, these symptoms should prompt evaluation by an eye care professional:
- Persistent redness, irritation, or pain in the eyes
- Blurred or double vision, or sudden changes in clarity
- New floaters, flashes, or dark spots
- Increased tearing or watering (or a sense of something in the eye)
- Light sensitivity or worsening glare
- Visual distortions or areas of vision loss
Early detection and communication with both your oncologist and your eye doctor can make a difference.
How Clara Vista Eyecare Supports Patients
At Clara Vista Eyecare, our goal is to help preserve comfort and vision, especially when eyes are vulnerable. Here’s how we can help:
- Comprehensive eye exams & retinal imaging
We use thorough eye health evaluations, including dilation and imaging, to monitor for internal changes. - Symptom management & supportive care
For dry eye, irritation, or tear drainage issues, we can recommend lubricating drops, adjust treatments, or help manage symptoms in collaboration with your oncologist. - Ongoing monitoring during and after treatment
Regular checkups allow us to spot subtle changes early, adjust care, or refer to specialists as needed. - Patient education & communication
We encourage patients to inform us of their full medical history—including cancer treatments—so we can tailor our care accordingly.
Tips for Protecting Your Eyes During Cancer Therapy
- Stay well hydrated and use good eyelid hygiene
- Use preservative‑free artificial tears to maintain eye lubrication
- Wear UV protective sunglasses outdoors to reduce light sensitivity
- Take frequent breaks from screens and ensure good lighting
- Inform your oncology team and your optometrist of any new ocular symptoms
- Keep follow‑ups and let your eye doctor know about any changes in medications

Breast Cancer Awareness Month is a reminder not only to promote screening and early detection, but also to look at the broader implications of a diagnosis—how treatments may impact daily life, including eyesight. At Clara Vista Eyecare, we aim to partner with you through all stages of care.
If you or someone you know is undergoing breast cancer treatment and is experiencing eye or vision symptoms, don’t wait. Schedule an eye evaluation with us—and let’s help protect vision during every part of your health journey.
