Ophthalmologists can detect the presence of cataracts by taking a medical history and performing a comprehensive eye exam that includes an acuity test, a slit-lamp exam, and a retinal exam.
In the earliest stages of cataracts, a person may not notice changes in their visions or other symptoms. That is why annual exams are so important.
Note: Cataracts are more common than you might think. More than 24.4 million Americans over the age of 40 have been affected by cataracts. By the age of 80, more than half of Americans have experienced cataracts.
