摘要:
A concentrator apparatus is disclosed. The concentrator apparatus includes a light receiver and a light concentrator. The light concentrator is arranged for the omnidirectional concentration of light toward a first focal point on the light receiver and a second focal point on the light receiver. For example, the light concentrator can include a first concentrating lens with a first focal point on the light receiver. The light concentrator can include a second concentrating lens with a second focal point on the light receive. The first and second concentrating lenses can be circumferentially spaced about the light receiver.

An aqueous contact lens storage solution comprises a viscoelastic rheology modifier; and not more than 0.3% w/v of an alkali metal salt; the solution has a pH of between 6.0 and 8.0 and an osmolality of between 100 and 400 mOsm/kg, and the solution has viscoelastic properties, even if heat sterilized at 121° C. for at least 15 minutes. The viscoelastic rheology modifier may be selected from the following acids or their alkali metal salts: hyaluronic acid, poly (acrylic acid), crosslinked poly (acrylic acid), poly (methacrylic acid), carboxymethyl cellulose, alginic acid and mixtures thereof. The alkali metal salt may be present in an amount of from 0.01% to 0.3% w/v, and be selected from sodium chloride, sodium bicarbonate, sodium dihydrogen phosphate, disodium hydrogen phosphate, trisodium phosphate, sodium tetraborate, sodium citrate, sodium acetate, sodium lactate, potassium chloride, potassium bicarbonate, potassium dihydrogen phosphate, dipotassium hydrogen phosphate, tripotassium phosphate, potassium tetraborate, potassium citrate, potassium acetate, potassium lactate and mixtures thereof. The solution may be an inhomogeneous combination of a gel component and an additional liquid component. If so, the solution has a pH of between 6.0 and 8.0 and an osmolality of between 100 and 400 mOsm/kg when in a homogeneous form.

An apparatus for spin casting lenses includes a rotatable tube, the rotatable tube defining a longitudinal cavity, wherein the longitudinal cavity is configured to receive molds. According to one exemplary embodiment, the rotatable tube is made of metal and includes a plurality of apertures configured to permit the transmission of actinic radiation.
摘要:
The present disclosure provides a contact lens package containing a contact lens in a compressed state. In one exemplary embodiment, the overall internal depth of the package is less than the natural sagittal depth of the contact lens. Different single-use contact lens package shapes and configurations may be used. In some embodiments, a spring disc is included in the packages to help present the contact lens to the user when the package is opened. The contact lens packages may be adhered or clipped to a card or other carrier sheet, and may be housed in a number of different secondary packages.
摘要:
A contact lens package that is reusable as a case to store a contact lens between uses includes a bottom member having a well with an inside generally concave shape, and a wall rising above the well and ending in a top rim defining an opening; a temporary seal comprising a moisture-proof film sealed across the top rim to seal the opening, thus defining a volume within the package, the volume containing a contact lens and contact lens fluid; and a cap secured to the bottom member covering the temporary seal, the cap being removable to give access to the temporary seal and replaceable on the bottom member thereafter to provide storage of the contact lens between uses thereof.The contact lens package and storage case can be used as part of a system having a generally flat base member with two receptacles and indicia identifying one of the receptacles as being for a left eye contact lens package and the other of the receptacles as being for a right eye contact lens package; and a plurality of contact lens packages each comprising: a bottom member configured to be received by one of said receptacles and held securely onto the base; a cap secured to the bottom member to enclose a volume; and a contact lens and contact lens fluid within the volume; wherein the plurality of contact lens packages include a generally equal plural number of packages containing a contact lens to be used in the left eye of a contact lens wearer and packages containing a contact lens to be used in the right eye of a contact lens wearer.
