If your cat gives you a slow blink, that is usually a friendly sign. Cats often use a slow blink when they feel relaxed, safe, and comfortable around you.
That is different from a true one-eye wink. A playful or relaxed slow blink usually involves calm body language, while a repeated squint, a held-shut eye, or a watery eye can point to irritation or pain.
What it can mean: a soft greeting, trust, or a way of saying they are at ease. Some cats also seem to slow blink when they want quiet attention, but not every cat uses the same signals.
When to worry: if one eye is squinted, red, cloudy, tearing, or has discharge, or if your cat is pawing at the eye, keeping it shut, avoiding bright light, or acting uncomfortable, it is time to call a veterinarian. Cornell and VCA note that squinting can show up with conjunctivitis, uveitis, corneal injury, and other painful eye problems, and Tufts advises vet care for eye discomfort, redness, cloudiness, or vision changes.
How to respond: slow blink back, keep your face and movements relaxed, and let your cat decide whether to come closer. If they look away, stop and give them space.

Bottom line: a slow blink is usually a friendly cat signal, but a persistent wink or squint is an eye-symptom first and a behavior clue second.
