Abstract

A method for fabricating a frameless diving includes the following steps. First, providing a lens; next, coating an adhesive on an edge of the lens; then, forming a first flexible layer made of a silica gel on the edge of the lens; thereafter, forming a second flexible layer made of another silica gel on the first flexible layer. The first flexible layer has a plurality of protrusions and may enables the lens covered with the first flexible layer to be spaced apart from a high-temperature mold for a proper distance, so as to prevent the first flexible layer from falling off from the lens due to the high temperature when molding the silica gel. The protrusions are exposed out of the second flexible layer, so as to vary the design and shape of the frameless diving mask abundantly.

- - 2. The frameless diving mask of claim 1, wherein the first flexible layer has a plurality of protrusions, and the protrusions are exposed out of the second flexible layer.
  - 3. The frameless diving mask of claim 1, wherein the second flexible layer extends toward one side of the lens to form a facial mask part.
  - 4. The frameless diving mask of claim 1, wherein the first flexible layer extends toward one side of the lens to form a facial mask part.
  - 5. The frameless diving mask of claim 1, wherein the color of the second flexible layer is different from that of the first flexible layer.
  - 6. The frameless diving mask of claim 1, wherein the second flexible layer is transparent or opaque.
  - 7. The frameless diving mask of claim 1, further comprising an adhesive coated on the edges of the lenses, wherein the first flexible layer is covered on the edges of the lenses and is adhered to the edges of the lenses by the adhesive.
  - 8. The frameless diving mask of claim 1, further comprising a lens holder which is mounted between the two lenses.
  - 9. The frameless diving mask of claim 8, further comprising an adhesive coated on the edge of the lens and the lens holder, wherein the first flexible layer is covered on the edges of the lenses and the lens holder and is adhered to the edges of the lenses and the lens holder by the adhesive.

10. A method for fabricating a frameless diving mask, comprising:
- providing at least one lens;
  
  coating an adhesive on an edge of the lens, and placing the lens in a first mold;
  
  performing a first molding process, to form a first flexible layer on the edge of the lens, and forming a plurality of protrusions and a spacing means on the first flexible layer;
  
  placing the lens having the first flexible layer in a second mold, wherein the lens is spaced apart from the second mold for a certain distance through the spacing means; and
  
  performing a second molding process, to form a second flexible layer on the first flexible layer, and to make the protrusions of the first flexible layer be exposed out of the second flexible layer.

- - 11. The method for fabricating the frameless diving mask as claimed in claim 10, further comprising a step of roughening the edge of the lens before coating the adhesive on the lens.
  - 12. The method for fabricating the a frameless diving mask as claimed in claim 11, wherein the step of roughening the edge of the lens is performed by milling or sand-blasting.
  - 13. The method for fabricating the a frameless diving mask as claimed in claim 10, wherein the first molding process is performed by injection molding or heat-pressing molding.
  - 14. The method for fabricating the frameless diving mask as claimed in claim 10, wherein the spacing means makes the thickness of the first flexible layer be greater than that of the lens.
  - 15. The method for fabricating the frameless diving mask as claimed in claim 10, wherein the second molding process is performed by injection molding.
  - 16. The method for fabricating the frameless diving mask as claimed in claim 10, further comprising a step of providing a lens holder, and placing the lens holder in the first mold and located between two lenses, wherein the adhesive is coated on the edges of the lenses and the lens holder, and after the first molding process, the first flexible layer is formed on the edges of the lenses and the lens holder.
  - 17. The method for fabricating the frameless diving mask as claimed in claim 10, the spacing means or the protrusions further positioning the lens having the first flexible layer on the second mold.
