Adjustable Glasses: Dial Vision, Eyejusters, and More

What are Adjustable Glasses?

Adjustable glasses are a versatile and affordable solution to correcting minor vision problems. They won’t replace regular glasses, but they work great in a pinch and make some activities much easier.

Also known as variable focus glasses and adjustable focus reading glasses, self-adjustable glasses allow wearers to see near and far. They’re similar to other multifocal lenses (bifocals and trifocals) but less expensive and available without a prescription.

Glasses with adjustable focus lenses are especially convenient for people with presbyopia (age-related farsightedness). They can correct other refractive errors, including:

Myopia (nearsightedness)
Hyperopia (farsightedness)

Pros and Cons of Adjustable Eyeglasses

Adjustable eyeglasses offer a variety of benefits, but they aren’t right for everyone. They offer convenience, but they tend not to work as well as prescription-strength glasses.

These glasses can be found at many retail stores and online from Amazon. Many of the benefits and drawbacks of adjustable glasses vary based on the brand, so research your options before choosing which is best for you.

How Do Adjustable Glasses Work?

Adjustable focus glasses feature fluid-filled lens technology that lets you adjust the lens power based on your vision needs. You twist the dial until you achieve optimal visual acuity. This is why they are sometimes called dial vision glasses.

Each lens on adjustable glasses has a membrane that moves outward or inward based on how much fluid the lens contains. The fluid comes from a small syringe in each arm of the glasses. Pumping fluid in or out of the lens changes its refractive power:

Correcting hyperopia (farsightedness). Pumping fluid into the lens increases its power, allowing you to see up close.
Correcting myopia (nearsightedness). Pumping fluid out decreases the lens power, providing clear distance vision.

How are Adjustable Glasses Different from Regular Eyeglasses?

With traditional lenses such as bifocals and progressives, small portions of each lens offer different types of vision correction. You’ll look through the top to see far away and down for objects near you. While convenient, this leads to a limited field of view.

With adjustable focus glasses, you have one focal length that varies depending on where you are looking.

These non-prescription glasses feature adjustment dials for far- and nearsighted correction. Adjustable glasses provide improved vision at all distances without requiring you to switch pairs of glasses or limit your field of view.
