More than 32 million Americans wear some form of over-the-counter reading glasses (OTC readers) to help with their vision. Some people may use a reader to help them focus on words up close, while others may use a reader to keep their eyes comfortable while reading and focusing on smaller objects. 

Reading glasses are common and have many benefits for the eyes. But if you're considering investing in the perfect reading glasses, it's important to understand how they work and what they do.

Read on to discover the science behind reading glasses.

Reading glasses are a great solution to the blurring and difficulty of seeing words and objects up close. They are often used by older adults because general wear and tear can damage our eyes and make it harder for our eyes to focus. If you tend to place menus further away in order to see them, you may need a pair of readers. How do reading glasses do this? 

Reading glasses magnify things like text to make it easier to focus. Your readers will have the strength of the lens that determines the size of the text display. There are varying degrees of universal strength, ranging from +0.25 to +0.7.00, and depending on the reading glasses strength you choose, the text becomes larger.

It is important to note that reading glasses are used for farsightedness or "hyperopia". This is indicated by a plus sign accompanying the strength of the reading glasses. Visionaries can see far objects well, but not near objects.

A minus sign indicates nearsightedness. Like glasses used to correct astigmatism, glasses to correct myopia are called "prescription readers." An optometrist or ophthalmologist will need to perform a comprehensive eye exam to give you these types of prescription lenses. 

Reading glasses will magnify text and help your eyes focus on them at normal distances instead of pulling menus farther to focus on words! Why do people have a hard time focusing on near text in the first place? 

One of the most common reasons for using reading glasses is presbyopia. Presbyopia is a condition that occurs with age. It usually starts at age 40 and progresses to age 65. While this may sound scary, it's perfectly normal and easy to fix! Here's some science behind what causes presbyopia and how it changes the lens of our eyes. 

The cornea and lens are two important structures in our eyes that help us see. They are responsible for refracting light entering our eyes so that our retinas can sharpen the images our brains process. 

The cornea bends the light that the lens muscle in our eye contracts to focus the image. The lens muscle contracts when looking at an object or word up close, and relaxes when looking at a word or object at a distance. These muscle movements of our eyes are essential for seeing and focusing.

However, over time, the lens of the eye becomes less flexible and cannot contract properly to focus on words or objects. This can lead to presbyopia - difficulty paying close attention to words and objects. Reading glasses are handy because they magnify text and objects, helping your eyes focus on them without having to hold a book or phone an arm's length away to see.

Many people associate reading glasses with impaired vision, but this is not the case. Anyone can use reading glasses. Most people look for reading glasses to reduce eye strain and improve their quality of life. 

Reading glasses can be prescribed by an ophthalmologist, but they don't have to be, nor do they require an eye exam or prescription for the reader. In other words, anyone can use reading glasses! Whether you're presbyopic or just want to make your eyes more comfortable when reading, you can wear reading glasses. 

It's also important to note that reading glasses won't hurt your eyes if you have perfect vision. They're designed to magnify text and text, but they won't damage your eyesight if you wear them all day (even when you're not reading) or if you "don't need" them to see. 

Reading glasses are a common accessory for people who are presbyopic or just want to make life easier for their eyes. The reader helps magnify text and objects so that the cornea and lens muscles of your eye can focus easily.
