As you age, you will find your eyesight changing in many ways. For most of us, that simply means an onset of presbyopia, or the aging of eyes that causes us to become more nearsighted. But thousands of others develop a more serious condition called cataracts. If cataracts are left untreated they will eventually cause blindness, but modern ophthalmology has found effective cataract treatment.
Cataracts are a condition of the lens where a cloudy or milky substance covers the lens, blurring or blocking vision. Cataracts are most common in older individuals but may develop at any age. This is a progressive condition which worsens without treatment. The most effective treatment is to replace the lens of the eye entirely. The technology for replacing the ocular lens has only become available within the last few decades, but is a relatively safe procedure with a very high success rate.
