Avaira Vitality™ lenses are highly breathable, bi-weekly replacement lenses designed with the same Aberration Neutralizing System™ as the Biofinity® family. The technology of a Avaira Vitality™ retains the lens surface moist all day, but also blocks transmission of 90% of UVA and 99% of UVB light*.

Many differences exist between brands of contact lenses which impact lens optics. The optics of the contact lens is determined by several factors including lens material1 and design2. Optics is the way in which the refraction of light is managed to maximize vision for the contact lens wearer3. Contact lenses with aspheric optics may provide enhanced vision for many wearers.

Lens design and the patient’s pupil size are key to multifocal success. The Biofinity Multifocal has a center-distance (D) lens, which transitions through an aspheric intermediate to an outer near zone for the dominant eye. A center-near (N) lens which transitions through an aspheric intermediate to a spherical peripheral distance zone, is placed on the nondominant eye7. When compared with monovision, multifocal contact lens correction provides great vision without compromising depth perception, with continuous adaptation over the first 15 days of wear8.

Fiber Optic is a great choice for bringing light into challenging to reach spaces. The optic strands are fairly flexible and they carry the LED source light out to the end of the strand.  They are great for lighting up elements that may be hard to fit LEDs into.

Contact lenses with aspherical optics can be extremely beneficial for subsets of your patients. By recommending a CooperVision® lens, you can be confident you are offering options in support of visual acuity, lens comfort, and eye health ‡.

MyDay® daily disposable are designed with the same Aberration Neutralizing System™ to provide optimal vision combined with UV blocking* and incredible comfort all day long. The MyDay® daily disposable is available in sphere, toric, and multifocal options.

The CooperVision® portfolio of monthly, bi-weekly, and daily lenses are designed with aspheric optics. The Aberration Neutralizing System™ utilizes aspheric optics to neutralize the aberrations from the eye in the Biofinity®, Avaira Vitality™ and MyDay® families. clariti® 1 day contact lenses also offer an aspheric optical design.

We have a new way to connect fiber optic. Choose 3mm connector for 3mm LEDs.  Choose 5mm connector for 5mm LEDs  It can hold one piece, or several pieces of fiber optics. The black color is very good at cutting down the side light from the LEDs. This will hold onto your LED very firmly.

Great prices and service as usual. Have been purchasing LEDs in the past, so when I say that they had the fiber optic I was looking for - it was a no brainer.

Biofinity Energys® and MyDay Energys® are designed for digital device users. DigitalBoost™ technology is an innovative single vision aspheric lens design that delivers a +0.3D digital boost, which helps reduce eye tiredness associated with digital eye strain. Study data demonstrates that devices users have a smaller change in accommodative micro-fluctuations (AMF) when wearing this DigitalBoost™ technology, suggesting reduced ciliary muscle stress when reading on a smartphone or other devices at a close distance9.

clariti® 1 day contact lenses also offer aspheric optics and provide silicone hydrogel at a comparable price to some hydrogel lenses13†. In addition, clariti® 1 day contact lenses feature high water content (56%), UVA and UVB blocker*, and a low modulus of 0.5 MPa, comparable with other hydrogel lenses. The clariti family also offers sphere, toric and multifocal options and is an ideal entry-level contact lens for new wearers14.

‡ With higher oxygen delivery than hydrogel materials, SiHy materials minimize or eliminate hypoxia-related complications during daily wear.

Regular spherical contact lenses have an even curvature across the entire lens surface; in contrast, aspheric lenses have varying curvatures across the surface changing from lens center to lens edge. Aspheric lenses are used to minimize optical aberrations within the human eye4. Parts of the eye including the tear film, cornea, and crystalline lens can induce aberrations. Contact lenses deliberately induce a level of aberration in the lens that is inversely equal to the amount of natural spherical aberration inherent in the eye to help give clear, crisp and sharp vision3.

I ordered a couple of lengths of fiber optics for a trial. The desired strands came in the mail in good time, undamaged, and were just what I was looking for.
