Euclid Vision Corporation is introducing its latest contact lens for myopia management: Be Free Day, a silicone hydrogel (SiHy) daily disposable.
Let’s start with a look at Euclid.
Euclid Vision is a global contact lens supplier specializing in advanced orthokeratology (ortho-k) and myopia management. Among its product offerings:
- Advanced corneal topographers
- Medmont Meridia
- Daily myopia lenses (our topic of discussion)
- Ortho-k lenses
- FDA-approved Euclid ortho-k lenses include the Euclid Emerald, designed for overnight wear to temporarily correct myopia
Now circle back to this new myopia-targeting lens.
The daily disposable Be Free Day lens was developed by Euclid Vision in collaboration with the Brien Holden Vision Institute (BVHI).
Its purpose: To incorporate a soft lens option into a pediatric patient’s daily myopia management routine.
- And key to its capabilities: A multistep optics design patented by BHVI.
A patented design? Tell me more.
This design’s dual-action technology is a proprietary, gradual multi-step optical approach "engineered to support effective peripheral myopic defocus” while also maintaining “high-quality central vision,” according to Euclid.
But more specifically: This design creates smooth, step-wise changes in refractive power across the lens optic zone while gradually transitioning optical power from center toward the periphery in controlled steps.
- The intended result: Less glare, halos, and ghosting
And take note: This differs from traditional multifocal (MF) or concentric ring designs, which involve sharp, discrete rings of power.
Go on …
The multistep optics also features a dual mechanism—with two defocus regions that signal the eye to slow axial elongation:
- Central treatment zone (for on-axis defocus to accommodate a wider pupil size range)
- Peripheral treatment zone (to create peripheral defocus)
The advantages of this: Reduced visual disturbances and visual acuity preservation.
What else to know about its design?
The SiHy lens incorporates an advanced biomimetic surface material designed to mimic properties of the tear film and eye, enabling enhanced wettability, deposit resistance, and consistent daily wear.
Per the company: These properties are intended to “help eyes feel less dry, relevant for today’s ever-increasing digital screen usage when there is typically reduced blinking.”
Speaking of the lens material …
That would be Toufilcon B (SiHy) with a 50% water content.
As for its parameters:
- -0.50D to -6.00D (0.25D per step)
- Class II ultraviolet (UV) protection
- Diameter: 4.2 mm
- Optic zone: 8.5 mm
- See here for more technical specifications (scroll to the last page)
Is training required for the lens fitting?
Nope! Euclid noted that the Be Free Day lens fit is similar to that of a standard daily disposable soft lens—allowing it to be integrated into eyecare practices “without additional equipment or workflow changes.”

Also keep in mind: A 10-lens trial pack is being offered as part of the Be Free Day lens launch to support initial adaptions, with the intent for ECPs to evaluate its “comfort, handling, and early visual performance” before a patient commits to fully wearing the lenses.
