Press-On Prisms (Fresnel): Lightweight, Adjustable Prismatic Correction for Visual Well-Being

Press-On Prisms, also known as Fresnel prisms, are a practical and discreet solution for prismatic correction that can be applied directly to eyeglass lenses. This thin, lightweight prismatic membrane is useful for various types of strabismus and oculomotor disorders, especially when the goal is to improve the interaction between the two eyes and reduce symptoms such as double vision.

What are Press-On Prisms?

A prism is an optical device that deflects the path of light. In visual terms, it can help compensate for misalignment, facilitate image fusion, and reduce fatigue related to maintaining binocular vision.

The Press-On version is designed to be applied to the surface of the lens: a convenient choice when you want a lighter solution than more "structured" prismatic lenses and, in many cases, easier to manage over time.

When They Can Be Useful

Press-on prisms are used in situations where the binocular component is impaired, for example:

• Diplopia (double vision) related to misalignments

• Strabismus (even with variable component)

• Oculomotor impairments of various origins, where it may be useful to modulate the correction over time

Naturally, the choice of prismatic power and orientation must be evaluated by a professional: this is what allows a "simple" product to be transformed into a truly effective correction.

Why choose a press-on prism

Those seeking prismatic correction often want two things: effectiveness and comfort. Press-On Prisms aim for precisely this balance.

Main advantages

• Lightweight: they don't weigh down the lens and are minimally invasive

• Adaptable: they can be custom-fitted to the lens and the area of ​​application

• Convenient handling: application is simple and requires no complex work

• Clinical flexibility: useful when testing or adjusting a correction before making a final choice
