What are vision changes?

Vision changes are any alterations in your ability to see normally and include blurred vision, cloudy vision, double vision, seeing spots in your vision, or loss of vision. Vision changes may occur in one or both eyes. Vision changes may originate in the eyes themselves or may be caused by many different conditions that affect the whole body.

Many vision changes are the result of simple refractive errors such as myopia (nearsightedness) or presbyopia (age-related farsightedness), which are easily corrected with eyeglasses or contact lenses. Another common and easily corrected type of vision change occurs with cataract, which is the gradual loss of transparency in the lens.

Vision changes may affect your ability to focus on objects at a specific distance or at every distance. Although anyone can experience vision changes, they are more common in older people, who are more likely to have chronic conditions that affect vision.

Although many vision changes are not serious, in some cases they may be caused by vision-threatening or life-threatening conditions. Because the causes of vision changes are so varied and may sometimes be serious, it is important to contact your health care provider promptly for diagnosis and treatment.

In some cases, vision changes can be a symptom of a medical emergency. Seek immediate medical care (call 911) if you experience vision changes, especially if they come on suddenly, along with other serious symptoms, including severe eye pain, severe headache, sudden loss of coordination, loss of consciousness, sudden weakness or numbness on one side of the body, or garbled or slurred speech, even if these symptoms are temporary.

Seek prompt medical care for any vision changes that cause you concern.
