4. Red Dots
Healthline
Having a red dot in the eye can be incredibly alarming, especially if it’s never happened before. Normally, a bright red dot in the eye means that you have a tiny blood vessel that popped, also known as subconjunctival hemorrhage. This can happen after coughing or straining, and while it may look scary, as long as it doesn’t hurt, it usually isn’t a hint of more serious problem. However, there are times when red dots or spots could be an indicator that your blood sugar is up, and the blood vessels end up becoming blocked and swell up as a result, causing the blood vessel to pop and bleed, and when left untreated, may even lead to impaired vision or blindness.
