1. A method of estimating a pressure in a subject, comprising:

  • with a component having an osculating surface that comprises a deformable material and that partially defines a closed control volume enclosed within an ophthalmic component, applying a force to the subject'"'"'s cornea, sclera, eyelid, or any combination thereof with the osculating surface while the osculating surface contacts a portion of the subject'"'"'s cornea, sclera, eyelid, or any combination thereof,the force being sufficient to collapse an intraocular blood vessel of the subject;

    visualizing the intraocular blood vessel through the component; and

    correlating the force that collapses the intraocular blood vessel to an estimated intracranial pressure of the subject.
