Presbyopia is a condition that occurs during the natural aging process of the eye. With age, the eye exhibits a progressively diminished ability to focus on near objects. The first signs of presbyopia are usually expressed between the ages of 40 and 50. To cope with presbyopia, people can either use several sets of corrective eyeglasses, each designed to focus at a different distance (not a very practical solution), or use a single pair of progressive eyeglasses.
In the case of progressive eyeglasses, the field of vision is segmented in order to enable varying viewing distances. Each distance has a narrow field of view, and in areas where segments overlap, an optical distortion is created. This condition causes significant discomfort: in order to see properly, people need to move their entire head, instead of just moving their eyes. The result is that users inevitably experience a long adaptation period and suffer from headaches and physical distress. Another unfortunate outcome is that many users simply fail to adjust to using these glasses, and give them up altogether.
Deep Optics is developing Omnifocals, the first ever dynamic focal eyeglasses. The eyeglasses are equipped with our cutting-edge technology sensors that detect the viewing distance and control the lens so that it adjusts its optical power automatically and effortlessly.
Our proprietary Liquid Crystal lens is large enough to cover the entire field of view of the eyeglasses and has the ability to electronically change its focal power. This allows for a clear view of both near and far objects without compromising the field of view. Thanks to the sophisticated lens, the entire field of view is used for viewing all distances and angles, giving the wearer a constantly sharp and clear image – the same viewing ability that a healthy eye naturally allows.

Deep Optics’ adaptive lens is based on Liquid Crystal, a birefringent material that has a different refractive index for different light polarizations. Liquid Crystal molecules change their orientation under electric voltage. By applying different voltage profiles to a liquid crystal layer, it is possible to control the effective refractive index of different areas of this layer.
In order to achieve high precision control over the liquid crystal layer, Deep Optics has developed a unique Liquid Crystal panel, similar to an LCD, with a very high resolution, transparent electrode grid. This dense electrode grid enables the application of high precision voltage profiles over the liquid crystal layer, without sacrificing transparency, or other optical properties. The result is a single panel that can implement many lens prescriptions, dynamically – positive and negative prescriptions, at a large diopter range and unlimited accuracy (not limited to 0.25D steps). The center of the lens can also be controlled in real-time; it can be positioned anywhere in the panel, and moved across the panel dynamically.
Deep Optics technology is also applicable for other worlds of content such as Augmented Reality (AR) and Virtual Reality (VR) wearable devices. In Virtual Reality, all virtual objects are displayed at a single optical distance, despite having different virtual distances from the eye. Similarly, in Augmented Reality, all digital data is displayed as an overlay applied to reality.
The overlay “distance” is fixed, and may be different from the distance of objects in real life. This discrepancy causes an effect known as the “vergence-accommodation conflict”, which frequently results in fatigue, nausea, eye strain and other symptoms of physical discomfort.
In these cases, Deep Optics’ dynamic lens technology can be applied to bring the user’s vergence-accommodation reflexes to an agreement, alleviating the negative side effects and providing a superior user experience.
Deep Optics is the inventor and pioneer of Omnifocals, dynamic focal eyeglasses based on its proprietary and patent-pending Liquid Crystal lens technology. The glasses are designed to allow the two billion people requiring multifocal vision correction to see the world naturally and seamlessly. The founding team has extensive expertise in the design of electro optical systems and integration into consumer electronics products.
