Description
- This application is a continuation of and claims priority to U.S. patent application Ser. No. 14/809,093 filed Jul. 24, 2015 entitled Stabilized Thin Lens, which claims benefit of and priority to Provisional Application Ser. No. 62/029,355 filed Jul. 25, 2014 entitled Stabilized Thin Lens, both of which are hereby incorporated herein by reference in their entireties.
- The present application relates to optical lenses and, more particularly, molded optical lenses formed with a stabilizing feature that prevents warping of the lens after formation.
- Relatively thin, optical lenses, such as lenses ranging from 0.5 millimeters to 3.0 millimeters in thickness, are common in the market place, however, there are several challenges to the production of such lenses. For example, in certain circumstances, relatively thin, polymeric optical lenses tend to warp or otherwise lose their intended form when removed from the lens mold in which they were formed.
- This problem is exacerbated in the case of thin, polarized, polymeric optical lenses. Polarized optical lenses are commonly produced by incorporating an absorptive polarizer formed by stretching a sheet of, for example, polyvinyl alcohol having iodine doping, into or on a base lens substrate. When a thin polymeric lens incorporating such a polarizer is removed from the lens mold, the stretched sheet attempts to regain its un-stretch form and thereby pulls and deforms the formed lens out of the lens's intended shape. This deformation can result in a lens having a “potato chip-like” or “saddle” shape. Lenses exhibiting such deformation are typically not acceptable in the market place. FIG. 1A is an example of such a deformed molded lens and
FIG. 1B is an example of a non-deformed molded lens. - In order to overcome this problem, manufactures may attempt to cool the molded lenses within the mold for increased amounts of time in the hope of achieving increased lens stability at decreased temperatures. However, this technique has the obvious disadvantage of decreasing throughput of lens production.
- What is needed in the art is a more effective means for stabilizing the molded form of a thin, polymeric lens after molding that does not impact production throughput.
- The present invention provides an effective means for stabilizing a thin polymeric lens such that, after molding or formation, the thin polymeric lens will maintain the intended molded form and/or geometry. This objective is achieved through the formation of a flange around all or a portion of a perimeter of the thin lens.
- These and other aspects, features and advantages of which embodiments of the invention are capable of will be apparent and elucidated from the following description of embodiments of the present invention, reference being made to the accompanying drawings, in which:
-
FIG. 1A is a perspective view of a deformed thin molded lens. -
FIG. 1B is a perspective view of a non-deformed thin molded lens. -
FIG. 2A is a perspective view of a flanged, thin, molded lens according to one embodiment of the present invention. -
FIG. 2B is a perspective view of three flanged, thin, molded lenses according to one embodiment of the present invention. -

FIG. 4 is a side elevation view of a flanged, thin, molded lens according to one embodiment of the present invention. -
FIG. 5 is a perspective view of a pair of flanged, thin, molded lenses according to one embodiment of the present invention. - Specific embodiments of the invention will now be described with reference to the accompanying drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. The terminology used in the detailed description of the embodiments illustrated in the accompanying drawings is not intended to be limiting of the invention. In the drawings, like numbers refer to like elements.
- The present invention provides an effective means for stabilizing a thin polymeric lens such that, after molding or formation, the thin polymeric lens will maintain the intended molded form or geometry. With reference to
FIGS. 2A through 5 , these objectives are, in part, achieved by molding the thinpolymeric lens 10 such that the lens is formed with a stabilizing rim orflange 12 around theperimeter 14 of the moldedlens 10. - The present invention is not limited by the polymeric material employed to form the
thin lens 10. The polymeric substrate or material may be a thermoset material or a thermoplastic material. With respect to thermoset materials, the substrate may include polymers from diethylene glycol bis (allyl carbonate) or diallyl diglycol carbonate, such as CR-39® from PPG, or Akzo Nobel brands NS205, NS200 and NS207. The lens substrate may also comprise other thermoset materials such as polymers of 1,3 butylene glycol dimethacrylate, acrylonitrile, allyl methacrylate, ethoxymethyl methacrylate, ethylene glycol dimethacrylate, polyethylene glycol dimethacrylate; ally esters; co-polymers of allyl esters with styrene or vinyl type monomers, such as diallyl maleate, diallyl phthalate, methallyl methacrylate, and high index copolymers containing, e.g., vinyl functionality, isocyanates, urethanes, sulfur-containing aromatic vinyl compounds, and bromine-containing aromatic acrylic compounds. - With respect to thermoplastic materials, the substrate may comprise polycarbonate resin such as that sold by Teijin, Sabic, and Bayer, Inc. of Pittsburgh, Pa. under various tradenames. The lens substrate may also comprise other thermoplastic materials such as polyamides, polystyrenes, polysulphones, mixtures of polycarbonate and polyurethanes, polyesters, polysulfones, polystyrenes, amorphous polyolefins, and acrylics.
- In certain embodiments of the present invention, as shown in
FIG. 2A , thelens 10 is tinted or colored by including a dye or tinting agent within the lens substrate. - In certain embodiments of the present invention, the
lens 10 is formed with a functional film or laminate incorporated within or on afront surface 16 or aback surface 18 of thethin lens 10. In certain embodiments, the functional laminate or film is incorporated solely within theperimeter 14 of thethin lens 10 and is not incorporated into the area of theflange 12. Alternatively, in certain embodiments, the functional laminate or film is incorporated within the area of thethin lens 10 as well as within all or a portion of the area of theflange 12. The functional attributes of the functional laminate may include, for example, tinting or coloration, anti-reflection, anti-fogging, hard coating, polarization, photochromism, and easy-cleaning. - In certain embodiments of the present invention, the
thin lens 10 has an approximately uniform thickness between thefront surface 16 andback surface 18 of 0.8 to 2.5 millimeters. In certain other embodiments of the present invention, thethin lens 10 has a non-uniform thickness between thefront surface 16 andback surface 18 that ranges from approximately 0.8 to 2.5 millimeters. - In certain embodiments, the
thin lens 10 of the present invention has acircular perimeter 14. The present invention is not limited by adiameter 20 of thethin lens 10. In certain embodiments, thediameter 20 of thethin lens 10 is approximately 65 to 85 millimeters. In certain embodiments, thediameter 20 of thethin lens 10 is approximately 75 millimeters. - In certain embodiments of the present invention, the
flange 12 is formed uniformly or symmetrically around theperimeter 14 of thethin lens 10. For example, if thethin lens 10 has a circular form orperimeter 14, theflange 12 may also have acircular perimeter 22. In certain embodiments, a width of theflange 12 from thelens perimeter 14 to aperimeter 20 of theflange 12 is approximately 5 to 20 millimeters. For example, in the case of athin lens 10 having a circular form and adiameter 20 of 75 millimeters and asymmetrical flange 12 having a diameter of 87.9 millimeters attached thereto, a width of theflange 12 would be approximately 12.9 millimeters. - Alternatively, in certain embodiments, the
flange 12 is formed asymmetrically around theperimeter 14 of thelens 10. Alternatively stated, the width of theflange 12 from thelens perimeter 14 to aperimeter 20 of theflange 12 is not substantially constant and is variable. - In certain embodiments of the present invention, the flange has a thickness between a
back surface 24 of theflange 12 and afront surface 26 of theflange 12 of approximately 0.5 to 3 millimeters. In certain embodiments, the thickness of theflange 12 will be less than a thickness of thelens 10 atperimeter 14. In certain embodiments, the thickness of theflange 12 will be greater than a thickness of thelens 10 atperimeter 14. - In certain embodiments of the present invention, the
entire flange 12 is positioned within a plane that is the same as or parallel to a plane in which thelens 10 resides or the same as or parallel to a plane that represents a best fit plane through thelens 10. Alternatively, in certain embodiments of the present invention, theflange 12 is in a different, non-parallel plane than the plane in which thelens 10 resides or a different, non-parallel plane than a plane that represents a best fit plane through thelens 10. - In certain embodiments of the present invention, the interface or attachment point of the
perimeter 14 of thelens 10 and theflange 12 forms a non-zero degree angle. - The
flange 12 is formed, for example, during molding or casting of thelens 10 in a flanged or flangeless mold or cast set-up. Theflange 12 may be formed of the same material or substrate as thelens 10, for example theflange 12 may be formed of polycarbonate. Alternatively, in certain embodiments of the present invention, theflange 12 is formed of a different material than that used to form thethin lens 10. - In practice, the
flange 12 may be removed from the molded lens during processing of thethin lens 10. Alternatively, thethin lens 10 may be process without removing theflange 12. This may advantageously assist in protecting and maintaining the geometry of thethin lens 10 up to the point that thelens 10 associated with a lens frame of other structure that may assist in maintaining the geometry of thethin lens 10. - Although the invention has been described in terms of particular embodiments and applications, one of ordinary skill in the art, in light of this teaching, can generate additional embodiments and modifications without departing from the spirit of or exceeding the scope of the claimed invention. Accordingly, it is to be understood that the drawings and descriptions herein are proffered by way of example to facilitate comprehension of the invention and should not be construed to limit the scope thereof.
