Do we need more light as we get older?

Is it that our eyes get less light, does our vision change somehow? Do lights have to be brighter? Does sunlight play a role?

More light was the solution to my problems. I went to my optometrist a few months back because, even with my glasses, which I normally only need for reading, I was having trouble seeing clearly. She explained to me that with age come subtle changes in vision and eye structure. Our pupil, for example decreases in size and is less responsive to lighting. Color vision declines; so colors become less bright, causing contrast between different colors less noticeable. And visual acuity, which gives us clarity and sharpness, also drops. The eye sees better in the light of day, so what she recommended was getting lights that emulated sunshine. If you go to your nearest Home Depot, get full-spectrum light bulb, and take into account the lumens, which is the brightness of the bulb, and the type of bulb. I would recommend at least 5000 lumens if you want light that feels like sunlight, and LED bulbs, which are long lasting and energy efficient. You’ll be surprised with the results!

The minute I turned 50, my eyesight became challenged and I realized that I needed twice the level of light in order to see well. And the poor lighting in my home wasn’t helping, so I went out and replaced all my light bulbs. I asked the vendor at the store what type of lighting I should get, I didn’t know if it was more brightness or more watts or what. He pointed out the full spectrum bulbs and I went with them. They are definitely brighter and I feel I can see colors and everything else more clearly. I don’t really know if this has to do with their so-called resemblance to sunlight, but in my case they seem to work like a charm. In any case, I think each person is different and has their own lighting needs.
