Princess Kate recently shared the uplifting news of cancer remission, bringing relief and joy to royal watchers around the world. The 43-year-old Princess of Wales has been gradually returning to her royal duties and was recently spotted attending an optician’s appointment in central London, signaling a return to normal life.
Although Kate has never been seen wearing glasses or mentioned using contact lenses, her visit to the optician may be linked to a lesser-known side effect of cancer treatment. According to Cancer Research UK, some chemotherapy, targeted cancer drugs and immunotherapies can impact vision by causing cataracts, optic nerve damage or changes in eye pressure. Symptoms may include blurred or dull vision, foggy vision, or even halos around lights.
Having undergone chemotherapy, it is possible that the princess will address these potential side effects to maintain her overall health. Her open nature about her cancer journey has been a source of reassurance to others battling the disease. When announcing her recovery, she acknowledged the challenges of adjusting to life after diagnosis, saying, “It takes time to adjust to a new normal.”

Kate isn’t the only royal to share their experience with the side effects of cancer treatment. His father-in-law King Charles spoke of losing his sense of taste during chemotherapy while speaking with an army veteran in Wiltshire last May. Similarly, Duchess Sarah Ferguson shared her battle with lymphedema after breast cancer treatment, encouraging others to seek out lymphatic drainage massages to ease symptoms.
As Princess Kate continues her recovery and gradual return to public life, her journey highlights the importance of addressing the long-term impacts of cancer treatment while offering hope and inspiration to others facing similar challenges.
