The utility model relates to the field of contact lenses, and discloses a
contact lens structure capable of improving tear film stability, which comprises a first
coating film and a second
coating film with nanoscale thickness, the second
coating film is wrapped on the first coating film, the first coating film is attached to a
contact lens main body, the first coating film is an inner hydrophobic layer, and the second coating film is an outer hydrophobic layer. The second coating film is an external hydrophilic layer; the edge of the first coating film is provided with a continuous bulge, the edge of the second coating film is provided with a double-arch structure which is matched with the continuous bulge in shape, a gap capable of containing
tears is formed in the center of the double-arch structure, and the
tears in the gap flow out when the first coating film is in a pressed state. According to the utility model, the rapid circulation of
tears is realized, the
protein deposition condition is reduced, the
evaporation condition of
moisture in the tears can be reduced, the
osmotic pressure of a tear film is ensured, and the stability of the tear film is maintained.
