Using TruFocals
1. How long will it take to learn how to use TruFocals?
Most users master focusing within minutes. You will be surprised at how easy and natural and intuitive it is. Over the first couple of weeks, focusing will become increasingly automatic. More and more, you will just do it unconsciously without thinking about it.
2. How often do I need to change focus?
In the beginning, you will probably re-focus frequently, in part because the result is so amazing! But, as you get more experience, you will find yourself re-focusing less often.
The first thing you will learn is that you don’t always really need to refocus. If you hear someone passing by your office, you can glance up from your computer and see that it is Joe without having to refocus your TruFocals. But, if Joe is walking into your office carrying something you really want to see, you will refocus without even thinking about it.
The second thing you will come to learn is that one of the key things about TruFocals is the ability to focus to ANY distance. Over time, you will start taking advantage of this by focusing your TruFocals so that everything you need to see for a given task is adequately sharp, without the need to re-focus.
If, for example, you are sitting around a dinner table or conference table, you will quickly learn to pick a focus distance that allows you to see everyone around the table satisfactorily without the need to re-focus.
Many TruFocals users find when they are driving that if they back off from the maximum distance setting just a little, the instruments of the car jump into readability, while objects in the distance are still surprisingly clear.
The key is the unique ability to pick the EXACT focus that works best for each situation.
3. Isn't it a nuisance to have to focus your glasses?
No, it's not…in part because our bodies are already equipped with the world’s best autofocus mechanism.
As young people, when we want to focus on something, our brain instructs the muscles in our eyes to adjust focus. When the object we are looking at is in perfect focus, the brain tells the muscles: “That’s it. Stop there!” Unfortunately, as a natural consequence of aging, the focusing ability of the eye loses its effectiveness.
It turns out, however, that exactly the same feedback mechanism continues to work when you use your finger to move the slider to focus your TruFocals. For this reason most people very quickly find that focusing becomes automatic.
4. Why not build in an autofocus mechanism?
In our modern, high-tech world, we are accustomed to thinking that the high-tech solution to any problem is always best.
But, sometimes simpler is better.
TruFocals already make use of the best autofocus circuitry in the world: the one built into our own bodies. Therefore, focusing soon becomes so automatic that you don’t even think about it.
In any case, you don’t refocus TruFocals all the time – only when you need to. Many times, you will find yourself focusing them to an intermediate position that adequately covers the exact range of distance you have to see for a given task.
A good autofocus system for glasses would almost have to read your mind to know when to focus, what to focus on, and what compromises to make to cover a range of distances. If it gets any of this wrong, even 10% of the time, the consequences are going to drive you crazy.
A good autofocus system for glasses should also be far smaller and lighter than any technology that currently exists, and ideally would not require a battery in your glasses.
Wait, here’s a better idea: use the amazing autofocus circuits already built into your body, and use your finger to activate the focus.
Sometimes simpler is a lot better.

Can TruFocals help me...
5. I have astigmatism. Can TruFocals help me?
Yes. TruFocals can correct most vision conditions, including nearsightedness, farsightedness, astigmatism, and even prismatic imbalance. Whatever conventional glasses can correct, TruFocals can correct…with the additional advantage of allowing you to adjust focus dynamically to give you perfect clarity for every distance from close-up to distant and anywhere in between.
6. I’m a computer user. Shifting my attention from the screen to other things in the room is annoying. Can TruFocals help me?
Yes! TruFocals make those adjustments instant and easy. No swapping glasses or tilting your head. Just a small movement of the slider on the TruFocals bridge does it. The American Optometric Association says that 90% of computer users suffer from computer eyestrain and that as many as 75% of them would benefit from special computer eyewear. Because you can adjust your TruFocals precisely for computer use, they satisfy that need. We even offer optional glare-reducing front lenses specifically intended for computer users.
7. Can I get TruFocals with tinted lenses?
All TruFocals inherently block harmful ultra-violet rays (both UVA and UVB). You can also order tinted interchangeable front lenses. We offer contrast enhancing and glare reducing tints for occupational and recreational activities, including aviation, computer use, fishing, golfing, etc.
8. Can I use TruFocals when I play golf?
Yes. TruFocals will keep your vision sharp from scorecard to green. They’re excellent for sports where razor sharp near, intermediate and far vision can help your game.
9. At night, will traffic look as sharp as when I wear conventional glasses?
Yes. And, unlike conventional zonal multifocals, such as bifocals or "no line" progressives, all cars – near and far and to the side – are in razor sharp focus.

Purchasing TruFocals
11. Do I need a special prescription for TruFocals?
Not at all. To make your custom pair of TruFocals, all we need is your regular prescription.
11. Why do you require prescriptions be no more than one year old?
Eyeglass prescriptions are usually valid for two years. When you order TruFocals we recommend that you update your prescription. That way you can enjoy all the benefits for the full life of your prescription.
12. What happens when my prescription changes?
TruFocals’ adjustable focus capability typically accommodates small changes in prescription; if the change is dramatic, however, you should replace your TruFocals. That’s one reason you should update your prescription when you order TruFocals.
13. Can I buy TruFocals from my regular eye care professional?
Yes. But, because TruFocals are a new technology, your eye care professional may not yet have heard of them. Send, fax, or email us your prescription and we will alert your eye care professional that you want to purchase TruFocals from him/her.
14. Is an eye examination for TruFocals more complicated than for regular glasses?
Not at all. In fact, eye care professionals report that an examination for TruFocals is less complicated. Because you will be able to control your TruFocals’ focus for any activity, on the fly, there is no need for determining the focal length(s) most suitable for your occupational or leisure activities.

15. Do they require any special care?
No. TruFocals include anti-reflective, anti-smudge, and anti-scratch coatings. Of course, as with all glasses, it’s a good idea to clean them regularly with a soft cloth and rinse with tap water to flush away any grit (which can, if rubbed into optical surfaces, cause scratches). Do not clean ultrasonically, as ultrasonic cleaning will cause permanent damage.
TruFocals are rugged and durable. Most moving parts are made from stainless steel alloy or TISMO high performance polymer. TruFocals users report that they stand up to the wear and tear of fulltime use.
16. How resistant are TruFocals to frost and high temperatures?
The optical fluid used in TruFocals is of high molecular weight and therefore won't freeze until very low, nor boil until very high, temperatures are reached. TruFocals have been tested in freezers and ovens -- and in Phoenix, AZ during the summer, and on Rocky Mountain slopes while skiing -- without ill effects. The operating range (where adjusting focus is quick, complete, and with excellent clarity) is from +25F to +125F, while the safe storage range is from -40F to +180F.
Of course, like ordinary eyeglasses, when moving quickly from warm interiors to cold outdoors, or vice versa, TruFocals can fog up temporarily.
17. How can I be sure TruFocals will fit me well?
Unlike most conventional frames, TruFocals are custom manufactured in bridge widths that correspond to the pupil distance (PD) shown on your prescription. They also have adjustable nose pads and arms that can accommodate nearly any face. This ensures a comfortable secure customized fit for virtually everyone.
18. Is there more than one style available?
While you can choose from several attractive colors, the optical technology behind TruFocals requires that, like any other focusing lens such as a camera or your eye, a TruFocals lens must be round. Starting from this requirement, we hired one of the world's premier design firms to create a unique, iconic design for our glasses.
19. How much do TruFocals weigh?
We have spent over a dozen years perfecting the design to make robust, adjustable focus glasses that weigh about the same as conventional glasses with standard frames.
20. What if I’m not satisfied with my TruFocals?
TruFocals come with a no-questions-asked 30-day money-back guarantee. Return them within 30 days and we’ll return your money. We even pay for the shipping.
21. Why didn’t anyone think of this before?
Over the years, a number of people have dreamed of the ideal solution: glasses that could focus sharply to any distance – just like a camera lens. But, until now, no one had figured out how to build such a lens into reliable, practical, thin and light eyeglasses. TruFocals required several technical breakthroughs and many years of testing and refinement.
