A small, thin lens designed to be worn directly on the surface of the eye to correct vision, serving as an alternative to traditional eyeglasses.
A lens that utilizes the surface tension of tears to adhere to the cornea, helping to address refractive errors in vision through direct application rather than external frames.
An optical device available in soft and hard varieties, intended for daily wear by people with vision impairments, providing a more discreet and versatile option compared to conventional eyewear.
A close companion or associate with whom one shares mutual affection and support, often involved in shared activities and experiences.

A device that uses electric and magnetic fields to bend and manipulate electron beams or electromagnetic waves for various applications, such as in electron microscopy.
A type of lens characterized by a central thickness that gradually tapers to a thinner edge, which is designed to converge parallel light rays to a focal point, commonly used in optical devices like corrective glasses for farsightedness and presbyopia, as well as in combination with concave lenses.
A lens that is thicker in the middle than at the edges, utilized for focusing light to a single point, making it essential in optical systems for enhancing vision or magnifying objects.
A lens with a convex shape that gathers light beams, redirecting them inward to create a concentrated beam, which is particularly effective in various optical applications, including eyeglasses and cameras.
A specialized lens designed to capture a wide field of view, typically over 180 degrees, allowing for a semi-circular perspective reminiscent of how a fish sees above the water's surface.
A convex lens characterized by its ability to produce an expansive, distorted image, often used in photography to create a unique visual effect by encompassing a broad scene within a single frame.
