If you have experienced this, don't fear. It's a natural part of getting up in years. Luckily, we can help you see clearly at all distances using our knowledge of optics, and the eye. This post will explain what is going on that causes you to need some help to see clearly up close. even though you have always been fine before.
To understand this, we need to consider how light enters the eye and is focused onto the retina to form a clear image. It is easiest to think of an individual who requires no glasses prescription, and has perfect vision (I know you glasses and/or contact wearers already dislike this person!) Light from a distant object (20 feet or farther) enters the eye, and forms a nice point focus on the retina, and the person sees a nice clear image without the eye needing to do any work at all.
As that object is brought closer to the person though, that point focus that fell so nicely onto the retina before, is now being pushed back "behind" the retina. In order for this person to see clearly now, the eye needs to use it's muscles and focus the light back onto the retina.
In our younger years, we typically have the power to focus this light onto the retina. As we age however, the focusing muscles start to diminish in their ability to focus this light for us. As a result, we need a little help to see clearly at near. That is where reading glasses or bifocals come in. They do the rest of the focusing that our eyes can no longer do for us.
The good part about this story, is that there are many different choices out there for you. You can hide the fact that you need some help with reading that great novel. We can help you find a solution that will work perfectly for you. Keep an eye out for our next post, in which some of the different options will be laid out for you.
