Warning signs of eye cancer that are easily confused with common eye problems include:
Blurry vision may be related to eye cancer you need to know to protect your health
One of the first signs of eye cancer is a sudden change or gradual blurring of vision. This is often mistaken for nearsightedness, farsightedness, or simply eye strain from electronic devices. However, if the blurred vision occurs in one eye, persists, and does not improve with rest, this could be a sign of melanoma developing inside the eye, according to the health website Verywell Health (USA).
Blurred vision occurring in one eye and lasting for a long time can be a sign of eye cancer.

The tumor may be pressing on the retina, distorting vision and causing loss of central or peripheral vision. According to the American Academy of Ophthalmology (AAO), any unexplained vision changes should be carefully evaluated with an ophthalmoscopy or ultrasound.
Black spots appear in vision
Having dark spots, shadows, or the sensation of "floaters" is often considered normal due to aging or changes in the vitreous. However, when this symptom becomes noticeable, persistent, or increases rapidly, it can be a sign of a tumor growing in the eye.
In the case of intraocular melanoma or lymphoma, the tumor changes the structure of the vitreous or causes retinal hemorrhage, leading to the above symptoms.
Pupils change color
The pupil in a normal eye is black and reacts to light. However, if the person or a loved one notices an unusual white or bright spot in the pupil when taking a photo, especially in children, it could be a sign of retinoblastoma.
In addition, tumors can also cause the pupil to dilate abnormally, lose its reflex to light, or become yellow-white. This change in pupil color can easily be mistaken for a birth defect or a side effect of medication.
Eye pain or feeling of pressure
Eye cancer is usually painless in its early stages. But as the tumor grows and spreads to surrounding tissues, it can cause pain in or behind the eye, which can be mistaken for headaches, glaucoma, or conjunctivitis.
Some patients describe a feeling of a foreign body in the eye, pressure when moving, or severe pain when touched. If eye pain is accompanied by blurred vision, eyelid swelling, or unusually dilated pupils, prompt evaluation is needed to rule out an eye tumor or cancer metastasis from another location in the body, according to Verywell Health.
