The own acquisition of a multifocal contact lens trial represents a critical junction for consumers experiencing the onset of presbyopia, a condition where the eye's natural lens loses flexibility, making it increasingly difficult to focus on close-up objects. This physiological shift typically becomes apparent around the age of 45, creating a significant challenge for those who prefer the freedom of contact lenses over the restrictive nature of reading glasses. For decades, the only viable solution for a contact lens wearer facing presbyopia was the requirement to wear reading spectacles over their existing lenses, a compromise that negated the primary aesthetic and practical benefits of contact lens wear. This necessity drove an era of intense research and development by global industry leaders, including Alcon and Johnson & Johnson, to engineer a solution that integrated multiple focal powers into a single lens.
The technical evolution of these lenses allows for the seamless incorporation of two separate prescription powers—one for distance vision and one for reading—within a single optical element. This innovation enables the wearer to focus on objects at varying distances, mimicking the functionality of varifocal spectacles. Since the introduction of the first soft multifocal lens by Bausch + Lomb in 1984, the market has expanded exponentially, now encompassing over 60 different brands produced by 15 different companies. This proliferation of options, ranging from daily disposables to monthly and annual lenses, means that a multifocal contact lens trial is no longer a luxury but a clinical necessity. Because the optical designs are complex, incorporating technologies such as aspheric optics, concentric circle designs, and translating lenses, the process of achieving the correct power is more intricate than with single-vision lenses. Consequently, a trial period is essential to ensure that the patient's unique visual needs are met before any long-term purchase is made.
The Mechanics of Multifocal Lens Design
Multifocal contact lenses, often referred to as varifocal contact lenses, are engineered to solve the specific problem of presbyopia. The primary goal is to eliminate the need for "readers" by providing a vision system that handles various focal lengths. This is achieved through innovative technical processes that allow the lens to handle distance and near vision simultaneously.
The impact of this design is that patients, whether they are myopic (short-sighted) or hypermetropic (long-sighted), can maintain their active lifestyle without the constant switching between glasses and lenses. The contextual significance of this technology is seen in the statistics of clinical adoption; between 2003 and 2019, the percentage of all contact lens fittings for presbyopes rose from 20% to 35%. Furthermore, the preference for multifocals over single-vision lenses among presbyopes doubled from 25% in 2005 to 50% by 2020.
The variety of available designs includes the following:
- Aspheric optics, which modify the curvature of the lens to reduce aberrations.
- Concentric circle designs, which use rings of different powers.
- Translating lenses, which shift position on the eye.
- Combination features, which merge multiple technologies for optimal clarity.
Manufacturer Innovations and Product Ecosystems
The landscape of multifocal contact lenses is dominated by several key players who have introduced specific technological advancements to improve the trial and wearing experience.
Alcon (formerly Ciba Vision) played a pioneering role in the sector, being the first to release a daily disposable multifocal contact lens in 1998, known as Focus Daily Progressives. This shifted the market by providing a hygienic, single-use option for presbyopes. Since then, Alcon has continued to iterate, offering options such as Air Optix Multifocal Plus HydraGlyde, which incorporates silicone hydrogel material for improved breathability and comfort.
Johnson & Johnson has similarly contributed to the field with the 1 Day Acuvue Moist Multifocal, leveraging pupil-optimised design to align the lens's optical zones with the wearer's pupil. Other specialised options in the market include the Proclear multifocal toric by CooperVision, designed for those who suffer from both presbyopia and astigmatism, as well as the Clariti 1 day multifocal.

The Multifocal Trial Process and Clinical Requirements
Securing a multifocal contact lens trial is not a simple retail transaction but a clinical process. Because multifocal lenses incorporate multiple powers, they are significantly more complex to prescribe than single-vision lenses. A specific prescription is mandatory, and the process of "dialling in" the exact powers requires precision.
The impact for the consumer is that they cannot simply switch to multifocal lenses based on their previous single-vision prescription. It is strongly recommended that every user undergoes a full sight test and a structured multifocal contact lens trial with a qualified Optometrist. This ensures that the balance between distance and near vision is optimized for the individual's specific visual habits.
The trial process has evolved based on the available lens types:
- Trial lens kits: Historically, these were impractical because the vast range of parameters made it impossible to stock every combination.
- Ordered trials: Traditionally, trial lenses had to be ordered specifically for the patient, necessitating a follow-up visit to test several combinations.
- Immediate on-eye experience: The introduction of B+L’s Ultra multifocal for astigmatism in 2019 changed this dynamic, as practitioners were provided with trial lens sets, allowing presbyopic astigmats to experience the lenses immediately.
Accessing Free Trials and Promotional Offers
For consumers seeking to reduce the cost of their initial transition to multifocal lenses, manufacturers provide avenues for no-cost trials. Alcon, for example, offers a system via the MyAlcon platform.
The process for obtaining these trials involves several steps:
- Creating a MyOffers account: Users must register through the MyAlcon portal to gain access to exclusive promotions.
- Profile creation: A user profile is required to log in and explore the available free trials.
- Coupon access: Beyond the lenses themselves, these accounts often provide coupons for over-the-counter eye care products.
The impact of these promotional programmes is that they lower the barrier to entry for presbyopes who may be hesitant to invest in a new lens type without first verifying that the technology works for their specific eyes.
Specialized Options: Astigmatism and High-Performance Materials
The integration of multifocal technology with other corrective needs, such as astigmatism, represents the current frontier of contact lens trials. Presbyopic astigmats face the most complex fitting process, as the lens must correct for the curvature of the cornea (astigmatism) while simultaneously providing multiple focal points (presbyopia).
The use of silicone hydrogel materials has been a transformative factor in these trials. This material allows for higher oxygen permeability, which is critical for long-term wear and ocular health. Research into bacterial adhesion to these lenses, such as that conducted on silicone hydrogel lenses, continues to refine how these materials are used to improve the wearer's experience.
Further specialized options available in the market include:
- Corneal Gas Permeable (GP) lenses: These offer different optical properties than soft lenses.
- Scleral and Hybrid lenses: These are used for more complex fitting scenarios.
- High-energy visible-filtering lenses: These are designed to reduce glare discomfort and improve photostress recovery time.
Analysis of Clinical Efficacy and Market Adoption
The transition toward multifocal contact lenses is supported by a growing body of clinical evidence and a clear shift in consumer behaviour. The doubling of the percentage of presbyopes fit into multifocal lenses (from 25% to 50%) indicates a high level of satisfaction and a perceived failure of the "reading glasses over contacts" model.
The efficacy of these lenses is not universal, which is why the trial process is so heavily emphasised. The success of a multifocal trial depends on the clinician's ability to choose between aspheric, concentric, or translating designs based on the patient's pupil size and visual demands. For instance, pupil-optimised designs are more likely to succeed in patients whose pupil size aligns precisely with the lens's focal zones.
The clinical impact of these advancements is further highlighted by the availability of specialized treatment trials, such as the PROTECT trial for progressive myopia treatment evaluation using NaturalVue multifocal lenses. This demonstrates that multifocal technology is being expanded beyond simple presbyopia management and into the realm of myopia control.
In conclusion, the multifocal contact lens trial is a sophisticated clinical journey that moves a patient from the limitations of presbyopia to a state of visual independence. The evolution from the first soft multifocal in 1984 to the current array of over 60 brands indicates a market that is highly responsive to the needs of the aging eye. The transition from impractical, order-only trials to immediate on-eye experiences, particularly for those with astigmatism, has streamlined the process. However, the inherent complexity of integrating distance and reading powers means that the role of the Optometrist remains central. The availability of free trials through manufacturer portals like MyAlcon serves as a critical entry point, allowing users to test these advanced optical technologies without financial risk. Ultimately, the success of a multifocal transition depends on the rigorous application of trial and error, guided by a professional, to ensure that the final prescription provides the necessary clarity for all distances.
