What is a Free Form Laboratory?
Redd optical laboratories is an optical laboratory which uses Free-form technology to make optical lenses. This is an optical laboratory equipped with cutting-edge automated machines which use a digital manufacturing technique called FREE FORM.
Free form technique makes use of computer-aided designs and surfacing to produce high-quality and higher definition customised optical lenses.
What are digital lenses?
Digital lenses (also known as Free-Form lenses) are made of the same materials as conventional lenses. What makes digital lenses different is the process by which they are made. To create these lenses, an advanced digital technology is used to resurface the lens allowing for greater precision over the entire lens surface.
This enables the prescription to be the same strength on the very outer edges of your lens as it is in the middle.As such patients can now have lenses customized to their specific unique prescriptions since the process offers several levels of personalization for patients and their lifestyles. Free-form lenses offer more visual comfort, improved peripheral vision, sharper definition and less eye fatigue.
Benefits of Freeform
| Benefit | Characteristic |
|---|---|
| Precision | Allows for sharper, clearer, crisper vision throughout the whole lens, giving you the best vision possible. Lenses can be refined 10 times more than a standard conventional lenses |
| Process | Uses advanced computer algorithms to incorporate lens technologies into the lens design, maximizing binocularity and optimizing the progressive corridor. |
| Software | Uses the latest software to enhance the viewing prescription and the corridor size as compared to a conventional lens. |
| Patient visual comfort | This allows the practitioner to tailor the lens design around the patient’s daily visual demands, making adaptation much easier. |
| Durability | All products come with UV, Anti reflective coating and anti-scratch film |
| Flexibility | Offers flexibility to the patient, allowing them to select the frame they want without compromising visual acuity or aesthetics. Patient is not limited on frame styles because of prescription needs. The most suitable base curve will be selected to match the frame choice, thereby improving aesthetics and comfort. |
Limitations of Conventional Lenses?
| Limitation | Description |
|---|---|
| Keyhole effect | Wearer has limited visual space on a lens |
| Peripheral distortion and blurriness | One of the main causes of discomfort is distortion at the edges of patient field of vision. |
| Off axis errors | Rx cyl axis not PAL axis -R & L lens see differently |
| Precision and accuracy | Limited to 0.125 to 0.25 diopter |
| Limited attention to aesthetics and lifestyle | Wearer might require a larger frame size to accommodate the multiple corrective zones. |
| Power changes as eye moves | Gets worse as cylinder Prescription (Rx) increases |
