Hey, I'm Reviewing Proper Focus Eye Glasses:!

Los Angeles, California

This ProperFocus exceptional affordable reading glass is flexible and adjustable. It comes with 2 glasses that are added with two side knobs to adjust the power -6 to +3 diopters. I just use the small knobs on the sides of the lenses to set the power. I will share more experience with the glass in the ProperFocus review.

According to Centre for Disease Control, CDC, approximately 12 million people 40 years and over in the United States have vision impairment, including 1 million who are blind, 3 million who have vision impairment after correction, and 8 million who have vision impairment due to uncorrected refractive error.

Vision disability is one of the top 10 disabilities among adults 18 years and older and one of the most prevalent disabling conditions among children.

Refractive errors are the most frequent eye problems in the United States and all over the world. Refractive errors include the following: myopia (near-sightedness), hyperopia (farsightedness), astigmatism (distorted vision at all distances), and presbyopia that occurs between age 40–50 years (loss of the ability to focus up close, inability to read letters of the phone book, need to hold newspaper farther away to see clearly) can be corrected by eyeglasses, contact lenses, or in some cases surgery. The National Eye Institute (NEI) states that proper refractive correction could improve vision among 150 million Americans.

Types of Vision Problems

  • The Most Common Adult Vision Problems
  • Blurred vision (called refractive errors)
  • Age-related macular degeneration
  • Glaucoma
  • Cataract
  • Diabetic retinopathy

The Most Common Childhood Vision Problems

  • Blurred vision (called refractive errors)
  • Crossed eyes (called strabismus)
  • Lazy eye (called amblyopia)

Before I exhaust everything you need to know about vision, the types, and the remedy for bad vision. Let’s talk about Adjustable glasses as a remedy for Poor vision/eyesight. An example of it is, Proper Focus.

What is Properfocus Glasses?

Properfocus is a type of adjustable focus eyeglasses. Adjustable focus eyeglasses are eyeglasses with an adjustable focal length. They compensate for refractive errors (such as presbyopia) by providing variable focusing, allowing users to adjust them for desired distance or prescription, or both.

Typically, current bifocals and progressive lenses are static, in that the user has to change their eye position to look through the portion of the lens with the focal power corresponding to the distance of the object. This usually means looking through the top of the lens for distant objects and down through the bottom of the lens for near objects. Adjustable focus eyeglasses have one focal length, but it is variable without having to change where one is looking.

Possible uses for such glasses are to provide inexpensive eyeglasses for people from low-income groups, developing countries, third world countries or to accommodate for presbyopia.

How Does Proper Focus Glasses Work?

There are currently two basic methods to achieve variable focal length: electro-optical and opto-mechanical.

Electro-optical often uses liquid crystals as the active medium. Applying an electric potential to the liquid changes the refraction of the liquid.

Early work on opto-mechanical methods was done by Martin Wright. Opto-mechanical spectacles allow focus control by the wearer via movement of a small slider located on top of the bridge. The user adjusts the lens for optical clarity at the desired distance. They are a combination of rigid and flexible lenses that can change prescription to enable sharp focus at different distances (from infinity up to 13″).

The appropriate addition range depends on the user’s level of refractive error. A tiny mechanism, actuated by the slider, simultaneously controls both flexible lenses to assure appropriate near vision tracking in both eyes.

Another type of opto-mechanical lens is the design of Joshua Silver, and uses liquid pressure against a diaphragm to control focus of a lens. These lenses were meant to provide improved vision without prescription by an optometrist, since these professionals are in short supply in many countries. Each eyepiece encloses a reservoir of fluid silicone and the user adjusts the level of fluid with a dial until they are satisfied with the result.

Stephen Kurtin also had a product based on what appears to be a related design called Superfocus (originally TruFocals). This company has since gone bankrupt.

Properfocus is an innovation on adjustable glasses with the following features.

Benefits of Proper Focus

  • Serves as Polycarbonate Lenses For Maximum Clarity and Resistance
  • Simple to Use By Everyone, Easy Adjustment and Position Fix
  • Instant Adjustment For Each Eye Independently
  • Precise Correction Based On Real User Feedback
  • Easy Reading With Maximum Clarity
  • Easy to Clean and Fingerprint Proof Glasses

First off, Polycarbonate lenses are ultra-durable, ultra-lightweight lenses. They are more than 10-times more impact resistant than your average plastic or glass lens. While they’re not the thinnest kind of lens out there, they still retain their position as the swiss-army-knife of eyewear lenses. With the right scratch resistant or digital protection coating, their potential increases even more.

Effects of Properfocus as a Polycarbonate lens

Polycarbonate lenses are more than just durable: they also have 100% protection from the sun’s UV rays! This kind of UV protection is an inherent part of the material they’re made out of, which glass and plastic lenses lack.

Fun fact: The material polycarbonate was originally used to manufacture the windshields of fighter planes!

Is Properfocus Glasses Legit?

with the aforementioned features of Properfocus, polycarbonates lenses are worth it. They’re durable and impact-resistant, lightweight and thin, and even offer extremely effective UV protection. At EyeBuyDirect, you can get a pair of polycarbonate lenses with your choice of frame for as low as $18! Considering their price and the many pros that come with polycarbonate lenses, they are definitely worth it in both the long run and short term.

Polycarbonate(Proper focus) lenses Prons and Cons

Clarity: A lens that’s optically clearer provides a better picture. Glass is superior in this category, which is why binoculars, telescopes, and cameras use it. Its superiority doesn’t mean polycarbonate lenses don’t provide a clear picture — just that glass offers more clarity.

Scratch resistance: A scratch on your lens will affect its clarity and your frame’s overall appearance. Glass and polycarbonate can both become scratched, but polycarbonate is less scratch-resistant, making anti-scratch coatings popular among glasses wearers.

Impact resistance: A lens with high impact resistance is less prone to cracking or shattering. While we love our frames, it’s not uncommon to drop them. Glass and polycarbonate lenses can handle occasional falls but aren’t invincible against long drops. Glass is the most vulnerable in this category. Polycarbonate is 10 times stronger.

Weight: A lens weight becomes noticeable when wearing your frames for long periods. Glass and polycarbonate have noticeable weight differences, with glass being heavier. In comparison, polycarbonate lenses are lightweight. You may notice the weight of your glasses by feeling pressure on the nose pads and temple tips.

UV Protection: A lens with UV protection is a must-have. While polycarbonate blocks 100 percent of UV rays, glass requires a UV protective coating. Both can offer UV protection, though.

Each lens offers advantages and disadvantages. Choosing the lens for your frames relies on you. If you’re sensitive to your frame’s weight, for example, polycarbonate lenses may be the right choice. Of course, if you’re unsure of which to choose, you can always contact your doctor for advice.

Properfocus Finger Print feature

If you own a pair of glasses, then there is probably one thing that irritates you more than anything else – well, when it comes to your glasses, that is.

Haha! Let’s see if you can relate.

When you notice your lenses are dirty, you take them off and clean them with your shirt. You put them back on and disappoint strikes once again because you notice they are still crawling with fingerprints.

If you are in the market for eliminating this irritating occurrence altogether, then you came to the right place.

First things first, you need to stop using your shirt to clean your glasses. While you’re at it, you can also stop using paper towels, tissues or something else that wasn’t specifically made for cleaning your lenses.


These types of materials can actually cause scratches, and dealing with that problem is the last thing you want. Not only could you damage your lenses, but your vision could take a hit until you fix them. Plus, having to schedule an appointment to fix them could lead to you missing some time at work, which could then lead to you getting behind. It’s a downward spiral, really.

This is one of good thing about Properfocus, it is fingerprint proof!

Advantages of Proper Focus

Unlike with bifocals, near-vision correction is achieved over the entire field of view, in any direction. Secondly, distance vision corrections are made by re-adjusting the lens for distance, instead of by tilting and/or rotating the head to view object through the best part of the lens for the distance.

Adjustable focus lenses (Properfocus reviews), like single-focus lenses, also reduce image-jump and spatial distortion in the field of view associated with traditional multi-focal lenses. Additionally, the ideal near-vision correction can be achieved with precision, because the variable lenses emulate the focusing action of the youthful (non-presbyopic) eye.

Disadvantages of ProperFocus

For all Adjustable glasses, the focal distance is changed by a mechanism located on the glasses, requiring periodic adjustment as the user switches his gaze to nearer or farther objects.

More on Types of Vision Problems – Properfocus review

Blurred vision

Nearsightedness (myopia) is when you can see clearly up close but blurry in the distance.
Farsightedness (hyperopia) is when you can see clearly in the distance but blurry up close.
If you are older than 40 and have trouble reading small print or focusing up close, this is usually due to a condition called presbyopia. One in every three people 40 years or older in the U.S. will need glasses to read smaller print.

Astigmatism is another condition that causes blurred vision, but it is because of the shape of the cornea.
These conditions affect the shape of the eye and, in turn, how the eye sees. They can be corrected by eyeglasses, contact lenses, and in some cases surgery.

What are the risk factors for developing Blurred Vision?

Family history – parent(s) who have one or more refractive errors
Advancing age – presbyopia affects most adults over age thirty five – 35
Crossed Eyes- strabismus
Strabismus occurs when the eyes do not line up or they are crossed. One eye, however, usually remains straight at any given time. Common forms of strabismus include:

Esotropia : one or both eyes turn inward toward the nose
Exotropia: one or both eyes turn out; also called wall-eyed
Hypertropia: one or both eyes turn up
Hypotropia: one or both eyes turn down
If detected early in life, strabismus can be treated and even reversed. If left untreated strabismus can cause amblyopia.

What are the risk factors for crossed eyes – strabismus?
Family history of strabismus
Having a significant amount of uncorrected farsightedness (hyperopia)
Disabilities such as Down syndrome and cerebral palsy
Stroke or head injury
Lazy Eye
Amblyopia — often called lazy eye — is a problem that is common in children.

Amblyopia is a result of the brain and the eyes not working together. The brain ignores visual information from one eye, which causes problems with vision development.

Treatment for amblyopia works well if the condition is found early. If untreated, amblyopia causes permanent vision loss.

What are the risk factors for lazy eye?
Premature birth
Low birth weight
Retinopathy of prematurity diagnosis
Cerebral palsy diagnosis
Intellectual disability diagnosis
Family history of certain eye conditions
Maternal smoking, drug or alcohol use
Surgery on eye muscles for esotropia (eyes turn in toward nose)
Diabetic Retinopathy (DR)
All people with diabetes, both type 1 and type 2, are at risk for DR. It is caused by damage to blood vessels in the back of the eye (retina). The longer someone has diabetes, the more likely he or she will get DR.

People with this condition may not notice any changes to their vision until the damage to the eyes is severe. This is why it is so important for people with diabetes to have a comprehensive eye exam every year.

There are four stages of DR. During the first three stages of DR, treatment is usually not needed. To prevent progression of diabetic retinopathy, people with diabetes should control their levels of blood sugar, blood pressure, and blood cholesterol. For the fourth stage of DR, called proliferative retinopathy, there are treatments that reduce vision loss, but are not a cure for DR.

Warning signs of diabetic retinopathy includes blurred vision, gradual vision loss, floaters, shadows or missing areas of vision, and difficulty seeing at nighttime.

People with diabetes are at greater risk for cataract and glaucoma as well.

What are the risk factors for diabetic retinopathy?

Type 1 or 2 diabetes
Poor control of blood sugar level
High blood pressure
High cholesterol
Being African American or Hispanic
Normal vision Vision with DR

Age-Related Macular Degeneration
AMD is a disease that blurs the sharp, central vision needed to see straight-ahead. It affects the part of the eye called the macula that is found in the center of the retina. The macula lets a person see fine detail and is needed for things like reading and driving.

The more common dry form of AMD can be treated in the early stages to delay vision loss and possibly prevent the disease from progressing to the advanced stage. Taking certain vitamins and minerals may reduce the risk of developing advanced AMD.

The less common wet form of AMD may respond to treatment, if diagnosed and treated early.

AMD risk factors?
Type 1 or 2 diabetes
Poor control of blood sugar level
High blood pressure
High cholesterol
Being African American or Hispanic

Note, there are different types of glaucoma, but all of them cause vision loss by damaging the optic nerve. Glaucoma is called the “sneak thief of sight” because people don’t usually notice a problem until some vision is lost.

The most common type of glaucoma happens because of slowly increasing fluid pressure inside the eyes.

Vision loss from glaucoma cannot be corrected. But if it is found early, vision loss can be slowed or stopped. A comprehensive eye exam is important so glaucoma can be found early.

What are the risk factors for glaucoma: Anyone can have glaucoma, but some people are at higher risk of developing the disease.
African Americans over age 40
Everyone over age 60, especially Mexican Americans
Those with a family history of glaucoma
Normal vision Vision with glaucoma

A cataract is a clouding of the lens of the eye. It often leads to poor vision at night, especially while driving, due to glare from bright lights.

Cataracts are most common in older people, but can also occur in young adults and children.

Cataract treatment is very successful and widely available.

Cataract risk factors?

Age, cataracts are more common after age 60
Certain diseases such as diabetes
Smoking and alcohol use
Too much exposure to sunlight
Normal vision Vision with cataract

Proper Focus Customer Reviews

This has pretty much changed my life. I was a bit apprehensive when I first purchased as I’m not the most technically savvy person out there but it didn’t take long for me to get to grips with the useful functions.

Jordan A.
So glad I purchased one, it didn’t take long to arrive but since I’ve had it I have to say it is my most used gadget. Unbelievable considering the price. I use mine everyday and life wouldn’t be the same without it now. The instructions are super easy to follow which is good because I’d never used one before.

Vera O.
Not the sort of thing I would usually purchase but glad I did. Now that I have it, everyone wants to know where I got mine from.

Is Properfocus Any Good?

  • The potential for correction of both distance and near vision, applicability for all ages
  • The empowerment of all categories of people because of it affordability
  • The increased participation of people augmented awareness of the mechanism of refraction, reduced costs of optical and refraction units in low-resource settings, and a relative reduction in costs for refraction services.

Other categories of Ajustable Glasses like Properfocus
Below are other types of adjustable glass according to wikipedia

Adaptive optics glasses have been suggested as another potential for adjustable eyeglasses.

Intraocular lens “CrystaLens” also replaces the normal eye lens with an adjustable one that is adjusted by using the eye’s focusing muscles to focus.

Electrowetting is a technology used to electrically adjust the path of light for vision

How to make Properfocus Eyeglass last longer

Don’t wipe lenses properfocus when they’re dry. Any debris on their surface or dust in the cleaning cloth could cause scratches.
Don’t wipe lenses with things that have a rough surface.
Don’t use ammonia, bleach, vinegar, or window cleaner, which can harm lenses and their coatings on Proper focus. (Most lenses are now coated, usually with an anti-reflective layer.)
Do not spit on your lens. While spit is a handy cleaning solution, saliva may contain oil or something else that’s damaging, says American Optometric Association spokeswoman Susan Thomas. Exhaling on lenses before cleaning doesn’t get them very wet, and the association doesn’t recommend it… Warning!
Don’t put unprotected glasses in a purse, pocket, or bag as it would likely be broken handled very roughly.
Do not regularly place glasses on a sink or vanity top. Spatter, sprays, and cosmetics can soil lenses, and hair spray or perfume can damage anti-reflective coating.
Do not leave glasses in a hot car. Especially avoid the top of the dashboard, the windshield will act like a magnifying lens.

Conclusion on Properfocus Reviews

Although common in the US, a refractive error such as nearsightedness is a highly treatable condition; with a simple visit to an optometrist, one can receive a pair of eyeglasses or contact lenses that can help correct poor vision. For people in developing countries, it is not so easy; with only one optometrist for every 600,000 people on average, most people with refractive errors go untreated. But one professor has come up with a solution: Adjustable Glasses of which Properfocus is a leading example.
