DETAILED DESCRIPTION OF THE INVENTION
The detailed description herein provides preferred embodiments of the contact lens (1) of the invention only for exemplary purposes and without imposing limitations in any respect.
Many nocturnal creatures dilate their pupils and maximize the light intensity to enable sight when it is inadequate in low light conditions. Similarly, human eye's retina can be illuminated to enhance sight in low light settings. This invention intends to enhance the visibility of objects by increasing the brightness of the image formed on retina without damaging the structural integrity of the eye. Therefore, the contact lens (1) of the invention in its most general form comprises a light source (3) placed between an inner surface (4) and an outer surface (2). The invention is a contact lens (1) to enhance visibility in low light settings and provide night vision; comprising
• a transparent inner surface (4) placed on the cornea layer,
• a transparent outer surface (2) covering the inner surface (4),
• a ring shaped light source (3) comprising an optical space (3.1) and placed between the inner surface (4) and the outer surface (2). Figure 1 and Figure 2 shows assembled and disassembled views of the contact lens (1) of the invention. The contact lens (1) comprises three main sections namely the inner surface (4), the outer surface (2) and the light source (3). The inner surface (4) is the part which gets into contact with the cornea layer and at the same time enables the light source (3) to be fixed accordingly on the right position on the contact lens (1). Therefore, a light source groove (4.2) is introduced on the inner surface (4) to enable this. At the center part of the inner surface (4), an inner surface protrusion (4.1) is formed to help fixing the light source (3). Both the inner surface (4) and the outer surface (2) are transparent in order to prevent obstruction of the eyesight.
The light source (3) which is introduced at the light source groove (4.2) on the inner surface (4) illuminates the retina layer inside the eye and provides brighter images to better distinguish the objects. At the center of the light source (3), an optical space (3.1) is introduced to prevent obstruction of the eye sight.
The optical space (3.1) and the inner surface protrusion (4.1) are concentric with the same dimensions in order to provide a good fit between the light source (3) and the inner surface (4). Since the inner surface protrusion (4.1) completely fills the optical space (3.1), the refractive index of the light and the sight are not affected. Even when there is not a light source groove (4.2) present, inner surface protrusion (4.1) enables fixing the light source (3) on the inner surface (4).
At the outermost part of the contact lens (1), a transparent outer surface (2) is provided in order to cover the inner surface (4) and the light source (3) to protect the eye from external effects. In an alternative embodiment of the invention, a groove can be introduced on the inner surface (4) to protect the light source (3). In order to provide this, an outer surface protrusion (2.1) and an outer surface light source groove (2.2) can be formed on the outer surface (2) as seen in Figure 3-a, Figure 3-b and Figure 3-c. In this alternative embodiment, the outer surface protrusion (2.1) is in contact with the optical space (3.1) and the light source (3) is placed on the outer surface light source groove (2.2).
Industrial application of the invention;
The inner surface (4) and the outer surface (2) of the contact lens (1) of the invention can be manufactured by means of two methods present in the background art:
- Manufacturing by molding technique; in this technique, the inner surface (4) and the outer surface (2) can be manufactured by forming the raw material inside a mold. Manufacturing by lathe technique; In this technique, the inner surface (4) and the outer surface (2) can be manufactured by forming the raw material in a computer assisted turning machine using a cutting bit.
The light source (3) introduced within the contact lens (1) comprises an optical space (3.1) at its center and manufactured in aspherical disc form. Thereby the optical aperture of the cornea and normal sight of the eye is left unobstructed. The light source (3) can be manufactured by various methods. One of these methods is using a phosphorescent material. Phosphorescent dyes and pigments are used in glow in the dark toys and lamp wall switches. These materials stores light energy and radiates when they are exposed to light. When the energy source is removed, they continue to spend this stored energy by radiating until this energy depletes. New generation Strontium-Aluminate materials and their derivatives can maintain radiation for 8-24 hours. Since this material is biologically inert, there are no associated effects on health. This material with a solid and crystal form can be manufactured in an aspherical disc form in accordance with the curvature of the contact lens (1) and can be placed inside the contact lens (1 ). Phosphorescent materials can store energy when they are exposed various kinds of light or radiation such as flashlight, daylight, ultraviolet and other nonvisible lights. Therefore, it is possible to charge the contact lens (1 ) inside a box or a packaging which contains an LED light source to keep it ready for use at all times. The separately manufactured light source (3) can be placed inside the light source groove (4.2) which is formed on the inner surface (4). The outer surface (2) is laid over and attached onto the inner surface (4). For the attaching process, CA derivative adhesives or polymer based adhesives can be used as currently known in hard-soft hybrid contact lens manufacturing. Thereby the contact lens (1) is produced.
The inner surface (4) and the outer surface (2) of the contact lens (1) of the invention has no effect on the night vision capability of the product. Also the light source (3) leaves the optical aperture of the eye and the form of the light source (3) can be designed based on the form of the contact lens (1). In this way, it is possible manufacture a corrective contact lens (1 ) for those with eyesight defects.
With the contact lens (1) of the invention;
Night vision is provided with a product having an ignorable size, volume and weight.
Eyesight is not limited since the image is obtained naturally by the eye. Furthermore, depth perception is still maintained. Since the amount of light produced by the light source (3) is constant, no excess light is produced in brighter settings. Therefore, generating an excessive amount of light and discomforting of the eye is prevented.
Since the pupils are dilated when brightness is increased and excess light is blocked, damaging the eye during a transition from darker to brighter setting is prevented.
