If my tone has been a little cheeky in this post, it’s because it’s hard to overstate just how much I use this guy. I’m constantly reaching for it while doing projects. In the span of writing this post, I blasted decades of gunk out of an old eBay VCR using my XPower. I feel like a corny TV pitchman right now, but it really is that useful.

The technology behind aspheric glasses and contact lenses is directly related to advances made in camera lens technology. Just like the human eye, some camera lenses are shaped in such a way that visual aberrations and distortion can occur in the images they capture. The shape of the eye can also contribute to distorted vision. That’s why lenses are specially designed to balance and correct for the unique shape of a person’s eye—and why the technology has had to come a rather long way.

I have always had a complicated relationship with canned compressed air. For a neat freak, it’s a vital tool. It keeps your keyboards clean, it blasts dust out of your gaming PC, and it gets gunk out of those hard to reach parts of devices. It’s an invaluable tool, an ally — heck, even a friend.

In general, many people with moderate to high need of vision correction for nearsightedness or farsightedness can benefit from the advances of aspheric lenses, particularly if worn in prescription glasses. Those with lower prescriptions will not see noticeable improvements to make the cost of aspheric lenses worthwhile. While some may want to try aspheric contact lenses, particularly those with bifocal rather than multifocal prescriptions, the benefits are mixed and should be discussed with your eye doctor. Those with astigmatism may not benefit as high as others and may be better off discussing toric lens options. Finally, aspheric lenses are a good option for many who use non-prescription reading glasses, too! If your readers are at a high reading power of +4.00 or higher, you may want to explore aspheric options.

I was ambiently aware of the XPower a while ago because I looked up various methods for keyboard cleaning (including this weird goo). I had seen it on the shelf at Micro Center and, like many things in that wonderful store, I thought, “Wow, that sure does sound really useful. I should buy that sometime.” Micro Center stocks two similarly priced models — this one and an almost identical-looking model, both of which are also available on Amazon — but I went with the latter because it had the word “cyber” on the box and, thus, was better. It turned out to be so good that I immediately sold several friends on it, including my friend who works at a cafe and needs to clean up coffee grounds all the damn time. They also make it in a bunch of fun colors, and the same company makes heavier-duty models specifically for pet grooming that are available through XPower and Amazon.

Aspheric lenses are slimmer, flatter optical lenses compared to traditional prescription lenses. These lenses are available in both glasses and contacts, making more stylish options available to prescription lens wearers than ever.

Not only are ‘coke bottle lenses’ a thing of the past, but aspheric lenses also offer a better degree of vision correction. When wearing traditional lenses, you may notice some visual distortion when you look anywhere other than the direct center of the lens. Aspheric lenses, on the other hand, promote a wider field of vision with better peripheral vision and more consistent overall image magnification, allowing for clearer and more accurate vision. This is the same reason many photographers prefer aspheric camera lenses - a wider field of vision means more of the beautiful world is accurately captured in a single glance.

Say hello, dear reader, to the XPower A-2S Cyber Duster. I want to tell you how much I love this little guy. I love it more than most tools in my home. I love it more than I love some of my relatives. Imagine, if you will, a tiny vacuum cleaner but in reverse. It’s a pretty straightforward concept. It has two power settings (pretty powerful and very powerful), a brush attachment, and a shorter nozzle that I can’t find right now but is probably in the cabinet where I keep all of my tools. It is an absolute game-changer.

An electric duster is not a one-to-one replacement for compressed air. Compressed air cans come with a thin plastic straw that comes in real handy when trying to get into very hard to reach places, and that’s just really hard to replicate. But what my duster lacks in precision, it makes up for in sheer power and cost savings. You don’t have to ration your electricity the way you do canned air, so it becomes very useful for making casual, quick cleaning sweeps. At its highest setting, this thing blasts away. You can knock stuff off of your nightstand at a distance with this bad boy.

Finally, as mentioned in the beginning of this article, aspheric lenses are also an option for some contact lens wearers. However, the performance of aspheric contact lenses, when compared with that of aspheric glasses, may leave something to be desired. Many find that regular, spherical contact lenses work just as well, if not better than the newer aspherical contact lenses do. With two primary options of aspheric contact lens prescriptions being bifocal and multifocal, visual aberrations can be corrected in the wearer. However, visual contrast may reduce slightly, while glare caused by driving at night may increase - particularly for those who wear multifocal aspheric contacts. For these reasons, aspheric contact lenses may not be for everyone.

Another factor to consider is that, due to their flatter profile and closer proximity to the face, aspheric lenses may produce noticeable reflections for some wearers. Anti-reflective coating is recommended for all aspheric lens wearers to eliminate any potential for visual distraction that reflections can cause.

I am constantly surprised by the number of people who do not have an electric duster, but everyone who has converted sings their praises. Jess Weatherbed doesn’t have the XPower but has a CompuCleaner and noticed a similar improvement in basic air quality. Another person online recommended the Metrovac DataVac ESD (a duster meant specifically for data centers) since at least one of Metrovac’s models also functions as a vacuum cleaner. I have not had a chance to do extensive side-by-side testing with these models, but I would bet those things blow pretty hard, too.

As the name implies, it is also a duster, which does not sound as important until you realize how much dust is inside the average human home. It’s a lot, and it loves hiding in places. I have a significant dust allergy, so I am anal when it comes to air quality. For a fun time, put an N95 mask on, turn on your air purifier of choice (I have a Coway Mighty because that’s the one everyone collectively agreed to buy), and go hog wild on the hard to reach places in your room of choice. You will be shocked by the amount of revolting gunk that you will discover in your house and how much the basic air quality will improve.

The major disadvantage of aspheric lenses is their price. These advanced vision correcting lenses cost more to manufacture than traditional lenses do, involving more steps, more precision, and more labor. If you have an extremely mild need for vision correction, then aspheric lenses may not be the most logical choice for you.

If the word aspheric is new to you, we’ll break down everything you need to know about what aspheric lenses are, how they work, and the benefits and drawbacks of wearing them. By the end of this article, you’ll feel primed and ready to discuss aspheric lenses with your doctor if they are of interest to you.

I’m not trying to be a cheapskate here, but a can of compressed air costs like five bucks, and I got air at home. Like, a whole lot of it, just floating around, not paying rent. Can’t I just shove that into a can? I think you see where this bit is going.

While traditional lenses have gone far to help the millions of people who suffer from farsightedness or nearsightedness, they add a marked spherical, convex curvature to the shape of the lens. This can distort the appearance of the eyes and facial areas. Traditional convex lenses can create a magnifying, bug-eyed effect on farsighted prescriptions or a minimizing, beady-eyed effect on nearsighted prescriptions. This noticeable curvature of the lens distorts the appearance of the wearer and the glasses alike, detracting from overall perceived attractiveness while also dealing an unnecessary blow to self-confidence.

With the advancement of aspheric lens technology, we now have more glasses frame styles available to more people than ever, with significantly less bulging of the lens and a lightweight feel for comfortable wear. These advanced lenses are cut to a slimmer profile, with much flatter curves that are strategically shaped depending upon the wearer’s prescription. This slim profile means that the glasses frames can sit closer to the face for a much more natural, streamlined look. This is a big advancement for folks with especially high prescriptions. If you’re in the market for aspheric lenses, limited frame materials, shapes, and sizes are no longer an issue, either.

Get an electric duster. It’ll clean your computer, it’ll clean your home, and hell, it may even clean your very soul. (Warning: individual souls may vary.)
