Presbyopia vs. Hyperopia: What's the Difference?  

If you had to make a list of some of the vision-related conditions and afflictions that are commonly mixed up and confused with one another, presbyopia and hyperopia would undoubtedly be right at the top. For a lot of people, the trouble stems from two particular areas: they both deal with farsightedness, and they both have very similar (read: confusing) sounding names.

But while the end result is the same - your eye is having trouble focusing on objects at certain distances away from your face - the journey you take to get to a presbyopia vs hyperopia diagnosis or vice versa is very, very different. In fact, these two conditions are NOT the same thing and should NOT be treated as such.

Therefore, the key to taking the corrective action you need involves knowing as much as you can about what each term actually represents.

Presbyopia vs Hyperopia: What You Need to Know

Presbyopia is an (unfortunately) very common visual condition that typically affects all of us right around the time we celebrate our 40th birthdays. For some people it may come later, for some it may come sooner, but one thing is for sure: eventually, it will come for us all.

It's officially defined as "a specific type of farsightedness that is caused by a loss of elasticity of the lens of the eye." Translated into terms that don't require a medical degree to fully understand, presbyopia essentially just means that as we get older, the lens of our eyes becomes harder and less elastic. Elasticity is pretty much the most important part of your eye's ability to focus on objects that are different distances away from you, and in particular those that are close to your face.

According to a study that was conducted by the United States Census Bureau, about 112 million (!) people in the US were presbyopic in 2006. To make matters worse, that number is predicted to expand to as many as 123 million by as soon as 2020.

Hyperopia is also a condition that deals with farsightedness, but from a slightly different angle. Hyperopia is a very particular type of refractive error where objects that are at a distance become easier to see than those that are closer to your face. For people with significant cases of hyperopia, their vision can actually get blurry when trying to focus on objects at any distance - "near" or "far" no longer matter at that point.

The key thing that separates hyperopia and presbyopia is the refraction error that was mentioned earlier. Refraction, by its definition, has to do with the way that light bends as it passes through one object to another. In this case, that object is your eye. For people with hyperopia, the shape of their eye is literally preventing light from focusing on their retina. Since the shape of someone's eye directly relates to the shape of their cornea, this can lead to these types of refractive errors occurring on a more regular basis.

Hyperopia has little to do with age, and can indeed affect both children and adults. It has more to do with people who have an eyeball that is "too short," so to speak, which in turn prevents light from being able to focus directly on the retina to provide you with the clear vision you need to go about your life in the way that you want.

Presbyopia vs Hyperopia vs the Clear Vision You Need When You Need it the Most

Yes, presbyopia and hyperopia are very common and they represent a major change to your vision. That's the bad news. The good news is that these are NOT problems you need to take laying down.

For many people, adjustable focus glasses like Adlens' own UZOOM lenses can provide the relief you need to continue to live your life without compromises - whether your eye is oddly shaped or your just getting older doesn't actually matter.

Unlike bifocals or trifocals, which require you to look through a different part of the lens depending on what you're trying to focus on, using adjustable focus glasses couldn't be simpler. They work using a simple "lens over lens" system that changes the focal power of the glasses depending on where those lenses are sitting at the time.

In layman's terms, if you wanted to focus on the small print in a book you were trying to read, you would just turn the dial on the side of the lens until your vision is as clear as you want. When the time came to shift activities and focus on something else, just turn the dial again and you're ready to go.

These types of adjustable focus glasses help correct your entire up close field of vision - not just the particular subject that you're looking at - so you'd definitely be hard pressed to find an option that was easier to use. They're also decidedly more convenient, as you no longer have to worry about carrying around (and eventually losing) different pairs of drug store readers with different strengths just because you never really know what you're going to get into next.

Thanks to advancements in vision technology like these, presbyopia and hyperopia aren't nearly as "scary" for most people as they used to be. With the right pair of adjustable lenses at your side, you'll probably quickly forget that you even have a vision problem at all.
