Definitions

  • the invention relates to a method for manufacturing a contact lens, comprising an optical zone and a periphery, wherein the optical zone is shifted with respect to the axis of the contact lens in such a manner that an inner prism is obtained with the desired prism dioptre, and to auxiliary tools to be used in this method.
  • a bifocal contact lens mainly corresponds with a standard contact lens, wherein the outer side of the lens in the distance zone is cut with a first radius and in the reading zone with a second radius, the second radius being substantially smaller than the first radius.
  • the optical zone and the periphery are cut in a usual manner centrically with respect to the axis of the lens.
  • the conventional bifocal contact lens shows a thickness of the contact lens in the distance zone at the lower side thereof which is relatively high.
  • the use of the conventional bifocal contact lens is found unpleasant.
  • a big lachrymal film is formed at the location of the relatively thick edge of the reading zone which affects the operation of the reading zone in a detrimental manner.
  • the invention aims to provide an improved method for manufacturing a bifocal contact lens of the above-mentioned type.
  • the method of the invention is characterized in that the optical zone and the periphery are eccentrically cut in the lens basic part, for example by means of an auxiliary tool with a mounting part for mounting in a lathe and a receiving space for the blank mutually shifted along the desired distance, an eccentric collet or a tool mounted eccentrically with respect to the collet.
  • this lens basic part is attached with its optical zone to a chuck in a usual manner.
  • this chuck is mounted on a spindle with a mounting pin with adjustable eccentricity, wherein the eccentricity is adjusted in such a manner that the blank will rotate centrically.
  • the lens basic part is cut eccentrically on the blank with the desired contact lens diameter, for example by means of the above-mentioned auxiliary tool, an eccentric collet or a tool located eccentrically with respect to the collet, whereafter the optical zone and the periphery are cut in the lens basic part centrically with respect to the blank.
  • a bifocal contact lens wherein the thickness of the reading zone is substantially lower so that the contact lens as a whole is thinner than the conventional contact lens.
  • the centre of gravity of the contact lens is located lower due to the eccentrically located optical zone, whereby the position of the contact lens on the eyeball is stable.
  • a much smaller lachrymal film is formed at the reading Zone, whereby the disadvantages of such a lachrymal film are substantially decreased.
  • the periphery has a larger size at the location of the reading zone and the lower edge of the contact lens at the reading zone has a higher positive strength which compensates the detrimental effect of the lachrymal film.
  • Fig. 1 is a front view of a bifocal contact lens obtained by the method according to the invention.
  • Fig. 2 is an axial section of the bifocal contact lens of Fig. 1.
  • Fig. 3 schematically shows the contact lens of Fig. 1 during use.
  • Fig. 4a-4g show subsequent steps in the manufacturing process of a bifocal contact lens according to a first embodiment of the method of the invention.
  • Fig. 5a-5c show some steps in the manufacturing process of a bifocal contact lens according to a second embodiment of the method of the invention.
  • Fig. 6a-6b show a side view and a rear view, respectively, of an auxiliary tool for implementing the method according to the invention.
  • Fig. 7a and 7b show a side view and a front view, respectively, of an auxiliary tool for implementing the method according to the invention.
  • Fig. 8a and 8b show auxiliary means to be used in the second embodiment of the method of the invention.
  • Fig. 1 and 2 show a front view and a side view, respectively, of a bifocal contact lens 1 comprising an optical zone 2 and a periphery 3.
  • the axis of the optical zone 2 is shifted with respect to the axis of the contact lens 1 in such a manner that an inner prism is obtained with the desired prism dioptre.
  • the contact lens 1 comprises a distance zone 4 and a reading zone 5.
  • Fig. 2 shows the different radii R1-R4, in which the different lens surfaces are cut.
  • the optical zone 2 has an axis 6 and is cut with the radius R1 which is usually indicated as basic curve radius.
  • the periphery 3 has the axis 6 in common with the optical zone and is cut with a radius R2 which is usually indicated as periphery radius.
  • the distance zone 4 has the axis 7 of the contact lens 1 and is cut with a radius R3 which is indicated as the distance zone radius.
  • the reading zone 5 has the axis 6 and is cut with a radius R4 which is indicated as reading zone radius.
  • the bifocal contact lens 1 described has the important advantage that the reading zone 5 is substantially thinner than the reading zone of the usual bifocal contact lens, wherein the optical zone and the periphery are provided centrically in the contact lens. Thereby the complete bifocal contact lens is thinner and the centre of gravity is located lower due to the eccentrically provided optical zone.
  • the reading zone 5 has a greater height than in the usual bifocal lens because it is not necessary to bevel the lower part, whereby the effective operation of the reading zone 5 is improved.
  • the lack of the bevel at the lower part of the contact lens 1 results in a reduced height of the lachrymal film on the contact lens.
  • the periphery 3 has a greater width at the location of the reading zone 5, in particular at the lower most edge of the reading zone, whereby the contact lens 1 has a higher positive strength at this part. This higher positive strength compensates the detrimental effect of the lachrymal film.
  • Fig. 4a-4g show schematically some steps of a first method for manufacturing the bifocal contact lens.
  • Fig. 4a and 4b show a section and a top view of a blank 8, on which a lens basic part with the desired diameter of the final contact lens is cut centrically in a usual manner.
  • the blank 8 with the lens basic part 9 is shown in Fig. 4c and 4d, wherein the optical zone 2 and the periphery 3 are cut with the axis 6 in the lens basic part, wherein for illustrating the shift of the optical zone 2, the axis 7 of the lens basic part 9 is also indicated.
  • a first auxiliary tool 10 is shown in Fig. 6a and 6b, which tool can be used to cut the optical zone 2 and the periphery 3 in the lens basic part 9 if a standard lathe is used.
  • This auxiliary tool 10 is provided with a mounting part 11, with which the auxiliary tool 10 is clamped in a collet of the lathe, and a receiving space 12 in which the blank 8 is attached with the unmachined side, for example by means of wax. As indicated by the axis lines of the mounting part 11 and the receiving space 12, these parts are mutually shifted.
  • a collet 13 shown in Fig. 7a and 7b which collet 13 is provided with an opening 14 for receiving the blank 8, which opening is shifted with respect to the axis of the collet 13 along the desired distance.
  • the blank 8 is attached with its optical zone 2 on a chuck 15 in a usual manner, wherein due to the eccentrically located optical zone, the axis 7 of the blank 8 is shifted with respect to the axis 16 of the chuck 15 (see Fig. 4e).
  • the chuck 15 is fixed on a mounting pin 17 with adjustable eccentricity of a spindle 18, wherein the mounting pin 17 is located eccentrically with respect to the axis 19 of the spindle 18.
  • the eccentricity of the mounting pin 17 is adjusted in such a manner that the axis 7 of the blank 8 coincides with the axis 19 of the spindle 18 (see Fig.
  • the distance zone 4 can now be cut with the radius R3 (see Fig. 2) in the usual manner on the contact lens 1.
  • the chuck 15 is mounted on a spindle 20 with centrical mounting pin 21, so that the lens basic part rotates around the axis 6 of the optical zone 2 and the reading zone 5 is cut with the radius R4 (see Fig. 2) on the contact lens (see Fig. 4g).
  • polishing is done in the usual manner after each cutting operation.
  • a truncation (not further shown) is made at the lower edge of the reading zone 5 in the usual manner and the edge of the lens is finished.
  • a lens basic part 23 with the desired diameter of the contact lens to be manufactured is cut eccentrically on a blank 22.
  • the auxiliary tool 10 or the collet 13 can be used.
  • the optical zone 2 and the periphery 3 can be cut in this case in the usual manner with a centric collet, so that the optical zone 2 and the periphery 3 will be shifted with respect to the diameter of the lens basic part 23.
  • the blank 22 is attached with its optical zone 2 on the chuck 15, for example by means of wax.
  • the axis of the blank 22 coincides with the axis 16 of the chuck 15, so that the lens basic part 23 is located eccentrically with respect to the chuck 15.
  • the chuck 15 is mounted on the spindle 18 with eccentric mounting pin 17 in such a manner that the axis of the lens basic part 23 coincides with the rotation axis of the spindle 18.
  • the highest point of the lens basic part 23 with respect to the blank 22 is marked on this blank, as schematically indicated by reference numeral 24, while in the same manner the lowest point of the mounting pin 17 is marked on the spindle 18.
  • the marks are thereafter brought opposite to each other.
  • Fig. 8a and 8b show some auxiliary means for mounting the lens basic part 23 in a very simple manner in the correct position in an accessory for cutting the distance zone 4 on the lens basic part 23.
  • These auxiliary means comprise in the first place a special chuck 25 with a fixed collar 26 and a rotatable collar 27.
  • the collar 27 is fixed on the chuck 25 by a friction coupling so that the collar 27 cannot be rotated unintentionally.
  • the chuck 25 has an opening 28 for mounting the chuck on the centric mounting pin 21 of the spindle 20.
  • First the chuck 25 with its end with the opening 28 is mounted in a holder 29 with receiving space 30, wherein a pin 31 of the holder 29 engages into an opening 32 of the fixed collar 26.
  • An adjustment ring 33 can be brought on the chuck 25, wherein a coupling pin 34 of the adjustment ring 33 engages into an opening of the rotatable collar 27.
  • the adjustment ring 33 has a marker line 36 which has to be aligned with the marker 24 of the blank 22 by rotation of the adjustment ring 33.
  • the chuck 25 is mounted in an accessory 37 having a receiving space 38.
  • This receiving space 38 is located eccentrically with respect to a tapered shaft opening 39 with which the accessory 37 can be mounted for example on the centric mounting pin 21 of the spindle 20.
  • the accessory 37 has a positioning pin 40.
  • the chuck 25 must be located in the receiving space 38 in such a manner that the opening 35 of the collar 27 engages this positioning pin 40.
  • the chuck 25 is fixed in the accessory 37 by means of a locking bolt 41.
  • this positioning pin 40 indicates the lowest point of the eccentrical receiving space 38, the centre line of the lens basic part 23 will be aligned with the axis of the tapered space 39. Now it is simple to cut the distance zone 4 with the radius R3 (see Fig. 2) on the lens basic part 23 by using the standard spindle 20 with centric mounting pin 21.
  • the reading zone 5 is cut by mounting the chuck 25 directly on the spindle 20 with centric mounting pin 21.
  • polishing is done in a usual manner and a truncation is provided.
  • the truncation is preferably provided before the distance zone 4 and the reading zone 5, respectively, are cut.
  • Fig. 8a and 8b has the important advantage that manufacturing these special contact lenses with shifted optical zone can be easily included in the series of operations for manufacturing usual contact lenses, wherein moreover the same apparatus can be used. Thereby, the costs for using this method are restricted.
  • shifting the optical zone can advantageously be applied in manufacturing single focus contact lenses too.
  • shifting the optical zone an inner prism is formed and the centre of gravity of the contact lens is lowered, whereby the so-called "high riding" can be countered.
