Acuitas 3 and Blink OMS sit at different points on the scale of optical software providers, and that difference shapes almost everything else in this comparison. Blink OMS is built and supported by a small UK-based company working closely with independent opticians. Acuitas 3 is built by Ocuco, a company that has worked exclusively in eyecare for over 30 years, developing software for independent practices, optical chains, and multi-site groups across the UK, Ireland, the Netherlands, Belgium, Sweden. Norway, Denmark, Canada and the US.
Neither size nor scale tells the whole story on its own. A smaller provider can mean a more contained system with a tighter support setup. A larger platform can mean greater flexibility across clinical records, equipment integration, and reporting, , with the infrastructure to support a practice as it grows. What matters most is a given practice actually needs.
The comparison below looks at how the two platforms handle pricing, clinical workflows, eGOS, dispensing, and reporting, drawn from publicly available documentation from both vendors. For anything specific to your setup, a demo with each vendor is the most reliable way to confirm fit.
Background on Each Platform
Blink OMS is an EHR for optometry, developed and supported by Generation.NET Ltd, based in Hungarton, Leicestershire. The platform is built specifically for independent opticians, with a stated focus on personal, friendly service from an independent software provider. Blink runs across desktop, tablet, and smartphone, and is priced per practice rather than per user, with no fixed-term contracts.
Acuitas 3 is Ocuco’s flagship on-premise or cloud-based EHR for independent practices and groups. Ocuco was founded in Dublin in 1993 and is now the largest optical retail software provider worldwide, with over 6,750 sites using its products across 88 countries. Acuitas 3 serves independent practices, optical chains, and multi-site groups across the UK, Ireland, the Netherlands and the US, with a design emphasis on connecting clinical and retail workflows within a single platform.
All feature and pricing information below is compiled from publicly available documentation on both vendors’ websites and is accurate to the best of our knowledge at the time of writing. Feature availability may change; always verify directly with each vendor before making a decision.
Pricing and Commercial Model
Blink OMS publishes its pricing. The core package is £95 per month plus VAT per practice, with unlimited users and no fixed-term contract1. That core package covers patient demographics, lifestyle questionnaires, patient recall, practice diary, notes and attachments, a standard examination module, contact lens examination, dispensing, stock control, lab and order management, and management reports.
A number of features sit outside the core package as optional add-ons. eGOS, fully integrated with the PCSE portal, is £25 per month plus VAT. SMS messaging for patient correspondence is £5 per month plus VAT plus the cost of each message. Online booking, allowing patients to book directly into the Blink diary, is £15 per month plus VAT. Postcode lookup is charged at 10p per lookup plus VAT.
Acuitas 3 is priced based on the size and complexity of the practice, with location count, user numbers, and modules required all factoring into the final figure. Practices considering Acuitas 3 should request a quote specific to their setup.
The two pricing models reflect different starting points. Blink’s core package covers day-to-day basics at a low monthly cost, with eGOS, SMS, and online booking available to add as needed, which keeps the entry price low but means the full feature set carries additional monthly costs once those add-ons are included. Acuitas 3’s quote-based model reflects the full scope of what a practice needs from the outset, including features that sit outside Blink’s core package as standard.

eGOS and NHS Workflow
Both platforms support eGOS, though the commercial arrangement differs. Blink OMS lists eGOS as an optional add-on at £25 per month plus VAT, fully integrated into the PCSE portal, allowing vouchers to be generated during dispensing, completed online, and submitted directly1. Acuitas 3 includes GOS forms and NHS payment reconciliation as part of its core integrated workflow, with voucher management connected directly to the wider patient record.
For practices with significant NHS volume, the question to bring to a demo is less whether eGOS is supported and more how each platform handles claim errors, rejections, and the connection between NHS activity and the rest of the practice data. Either way, it’s worth asking each vendor directly about the full cost of eGOS as part of your evaluation.
Clinical Records and Equipment Integration
Blink’s clinical record functionality centres on a standard examination module alongside a contact lens examination module and a lifestyle questionnaire, with notes and attachments stored against the patient record. The platform’s public documentation describes some degree of form-level customisation, but does not detail workflow configurability by visit type, and equipment integrations are not listed as a feature.
Acuitas 3 structures clinical records around the full patient visit, with exam workflows configurable by visit type and documentation that spans every stage of the patient journey. The equipment integration portfolio is described by Ocuco as the largest in the optical industry, covering imaging, refraction, and dispensing devices from multiple manufacturers. Practices with specific diagnostic equipment, or those planning to expand their device setup, should confirm compatibility directly with Blink before making a decision, given the limited detail available publicly.
Dispensing and Stock Management
Acuitas 3 includes real-time stock visibility across sites alongside validated dispensing: a live check that confirms whether a specific frame and lens combination can be made before the order is placed. This capability draws on Ocuco’s deep optical lab industry expertise.
As the developer of Innovations, one of the world’s leading lab management systems, Ocuco brings a level of supply chain understanding from practice to lab that goes beyond what a practice management software provider typically offers. That validation step is designed to reduce remakes significantly, and for practices where dispensing errors are an ongoing concern, it is worth exploring in a demo. Acuitas 3 also includes order tracking for jobs sent to external labs.
The optical inventory management software layer in Acuitas 3 runs alongside dispensing, tracking stock in real-time across all sites, which becomes more relevant as practice complexity grows.
Blink OMS includes dispensing, stock control, and lab and order management as part of its core package. The public documentation describes these as included features without detailing the level of validation, or whether stock data syncs across multiple practice locations, which is relevant for practices running more than one site under separate Blink subscriptions.
Recall and Patient Communication
Blink OMS includes patient recall as part of its core package, built around ‘Patient Type’ and ‘Simple Recall’ features designed to target the right patients for specific appointments. SMS messaging is available as an add-on at £5 per month plus VAT plus the cost of each message, and is positioned specifically around reducing missed appointments by sending reminders to patients ahead of upcoming clinics.
Acuitas 3 handles automated recall across email, SMS, and letter, with marketing tools built into the same environment. Practices with multiple locations can monitor all communication activity centrally rather than managing it separately per site. Patient communication in Acuitas 3 sits within a fully GDPR and DPA compliant workflow, with a full audit trail, relevant for practices in the UK and Ireland alike. For practices operating in the US, HIPAA-compliant patient communication for optometry is also covered within the same workflow.
Reporting and Business Intelligence
Acuitas 3 integrates Microsoft Power BI for reporting, giving practices dashboards they can customise by site, clinician, time period, and revenue stream. Tracking the right optometry practice KPIs becomes more straightforward when the reporting layer is built to surface them across the whole business in one place.
Blink OMS includes management reports as part of its core package. The public documentation does not provide detail on whether reports can be customised, filtered by clinician or time period, or how reporting works across multiple practice locations. Practices that rely heavily on performance reporting should ask Blink to demonstrate the reporting module directly.
Scale and Multi-Site Considerations
Blink OMS is priced per practice, which means each additional location operates as its own subscription with its own core fee and add-ons. The public documentation does not describe a centralised view across multiple practices, which is worth raising directly with Blink for any practice operating, or planning to operate, more than one site.
Acuitas 3’s multi-site design is built around centralised reporting, shared clinical standards, and an omnichannel patient overview that connects online and in-practice touchpoints across locations. That architecture reflects why software matters for a multi-location optometry practice from the outset, rather than being assembled through separate subscriptions as a second or third site is added.

Security and Data Protection
Acuitas 3 is backed by ISO 27001-certified practices and SOC 2 Type II certification, alongside GDPR and DPA compliance and a full in-platform audit trail. For practices operating under formal governance frameworks, or that form part of a larger group with compliance obligations, those certifications provide a documented standard rather than a general assurance.
Blink OMS describes itself as a secure, cloud-based, GDPR-compliant system, with the stated benefit that practices no longer need to manage their own backups and disaster recovery. Its public documentation does not list ISO 27001 or SOC 2 equivalents. What transitioning to cloud-based optometry EHR means for data governance is worth raising directly with Blink, given the limited detail available on its current compliance position.
Which Practice Each Platform Suits
Blink OMS suits small independent practices that want a straightforward, low-cost system with no fixed-term contract, where the core package covers day-to-day patient management and additional features like eGOS, SMS, and online booking can be added as needed. Blink describes its offer as “personal, friendly service” from a small, independent UK provider, which may appeal to practices that prefer working with a compact team.
Acuitas 3 suits practices that need clinical depth, a broad and tested equipment integration portfolio, validated dispensing to reduce remake costs, and reporting that scales as the business grows. The SOC 2 Type II certification and full audit trail make it the stronger choice for practices with formal compliance requirements, and the omnichannel architecture holds up across single-site independents and larger multi-site groups.
Taking the Next Step with Acuitas 3
For practices building a software foundation with room to grow, Acuitas 3 connects clinical records, practice management, dispensing, eCommerce, and reporting in a single platform without requiring additional tools or subscriptions as the practice expands. The equipment integration depth, the validated dispensing layer, and the Power BI reporting architecture are features that tend to matter more as volume and complexity increase. A demo is the most direct way to see how that looks with your specific workflows. Book a demo with Acuitas 3.
