Changes to your vision might be small and go unnoticed, but when you notice that something has changed, that is the time to see an ophthalmologist for an eye examination.
Examples of vision changes that are not critical but should be checked include:
- Unusual trouble adjusting to dark rooms
- Difficulty focusing on near or distant objects
- Squinting or blinking due to unusual sensitivity to light or glare
- Change in color of iris
- Red-rimmed, encrusted or swollen lids
- Recurrent pain in or around eyes
- Double vision
- Dark spot at the center of viewing
- Lines and edges appear distorted or wavy
- Excess tearing or "watery eyes"
- Dry eyes with itching or burning
- Seeing spots, ghost-like images
However, if you experience any of the following changes, see an eye doctor right away or just go to your local ER, as they may be serious and require immediate attention:
- Sudden loss of vision in one eye
- Sudden hazy or blurred vision
- Flashes of light or black spots
- Halos or rainbows around light
- Curtain-like blotting out of vision
- Loss of peripheral (side) vision
Remember that regular eye exams are recommended—especially for those with some chronic health conditions such as diabetes and high blood pressure. Early detection and treatment can be the key to preventing sight loss.
