Adjustable glasses

Adjustable glasses, also commonly referred to as adjustable focus glasses or variable focus eyeglasses, are glasses with multifocal lenses. They allow you to adjust the power of the lens by turning a dial inside the adjustable eyeglass frame until you get clear vision at all distances. This eliminates the need to get multiple pairs of glasses. Keep in mind these eyeglasses are not a replacement for your prescription glasses. You can use them as a temporary or backup option in case something happens to your regular pair.

Why Would You Need Adjustable Lens Glasses?

Dial vision glasses can correct refractive errors like hyperopia (farsightedness) and myopia (nearsightedness). Depending on the brand, these glasses can adjust lens power from -6 diopters (D) to +4 diopters (D). Adjustable eye glasses can also make reading, watching TV and using electronic devices easier for individuals with special vision needs. These glasses are especially useful for people with presbyopia, a condition mostly associated with middle to old age, which limits people’s ability to see things clearly up close.

How Do Adjustable Eyeglasses Work?

Some Adjustable vision glasses use a fluid-filled lens technology that features a small syringe that pumps a silicone solution in or out of the lenses with a simple turn of a dial. Pumping the liquid in increases the power of the lens, correcting farsightedness. When the liquid is pumped out, it corrects nearsightedness. The method of adjustment varies from brand to brand. Some glasses have a knob on the side of the frame, while others have a small slider on the bridge of the frame.

Other eyeglasses use two lenses that slide over each other. The knob on the frame allows you to shift one of the lenses until optimal vision is reached.

Are Adjustable Reading Glasses Only for Reading?

No. Adjustable focus reading glasses are designed to correct near vision tasks like computer & phone use, hobby work, DIY and more. These glasses do not correct distant vision or are not recommended for use when driving.
