Question

Quizplus · Accepted Answer

As we age, the lens of our eye becomes less transparent, reducing the amount of light that reaches the retina. By the age of 60, the retina receives only one-third (or 33%) as much light as it did at 20 years of age. This can lead to difficulties with vision in low-light conditions and may contribute to the development of conditions such as age-related macular degeneration.
