Lenses
Lenses are pieces of glass or plastic used to focus light or correct vision problems in optical instruments, such as eyeglasses, cameras, and microscopes. They can also refer to the transparent or translucent part of the eye that focuses light.
Lensing
Lensing refers to the bending or curved distortion of light that passes near a massive object, such as a star or black hole, due to its gravitational field. This phenomenon was predicted by Albert Einstein's theory of general relativity and has been observed in various astronomical contexts, including the bending of starlight around the Sun during solar eclipses and the gravitational lensing of distant galaxies by foreground galaxy clusters. Lensing can also be used as a tool to study the properties of celestial objects, such as their mass and gravity.
Lensman
Lensman refers to the protagonist in the space opera pulp fiction series "Lensman" by E.E. Smith. The character is Arin Voura (also known as Kimball Kinnison), a space hero who fights against the evil Мал็อต (Martiens) and other alien threats. The term "lensman" has since been used to describe a space hero or a defender of the galaxy, often drawing inspiration from Kinnison's adventures and bravery.
Lensometer
A lensometer is an optical instrument used to measure the power and axis of a refracting lens, such as a glasses lens, contact lens, or intraocular lens. It is commonly used in the field of optometry and ophthalmology to accurately determine the prescription of a patient's eyes. The instrument typically consists of a device that reflects a beam of light through the lens, allowing the examiner to measure the magnitude and orientation of the lens's refractive power.

Lenten
Lenten refers to the period of 40 days before Easter in the Christian calendar, observed as a time of fasting, prayer, and penance. It begins on Ash Wednesday and ends on Holy Thursday, leading up to Easter.
Lententide
Lententide is an archaic or poetic term for the season of Lent, which is a period of 40 days before Easter in the Christian calendar. It is derived from the Old English words "lent" meaning "spring" and "tide" meaning "season".
Lentibulariaceae
Lentibulariaceae is a family of aquatic plant species, commonly known as bladderswursts or bladderworts. They are carnivorous plants that obtain essential nutrients by capturing and digesting small organisms such as protozoa, rotifers, and even planarians.
Lenticel
A lenticel is a type of natural opening or pore found in the stems and branches of some plants. It is a small, usually bead-like or blister-like structure that allows for gas exchange between the plant and the environment, allowing carbon dioxide to enter and oxygen to escape. Lenticels are also involved in the transportation of water and nutrients within the plant. In contrast to stomata, which are small openings found on the underside of leaves, lenticels are typically found on the stems and branches of plants.
Lenticellate
Lenticellate refers to the branching, spotted, or net-like arrangement of lenses in the bark of a tree or shrub, typically found in deciduous species. The term is often used in forestry and botany to describe the characteristic bark patterns of certain trees, such as the Acer rubrum (Sugar Maple). The name is derived from the Latin words lentil, meaning lentil, and cellulare, meaning to form cells.
Lenticels
Lenticels are small openings on the surface of a plant stem, branch, or root that allow for the exchange of gases between the plant and the environment. They are similar to stomata, but instead of being responsible for photosynthesis, lenticels provide an alternative means for the plant to breathe and release excess carbon dioxide.
Lenticles
Lenticles are small, dome-shaped organs found on the surface of some leaves, particularly those of cacti and succulents. They are made up of modified stem tissue and are thought to aid in gas exchange, allowing for more efficient exchange of oxygen and carbon dioxide between the plant and the atmosphere. Lenticles can also help regulate water loss by providing an additional route for water vapor to escape from the leaf, reducing transpiration and conserving water.
Lenticula
Lenticula (plural: lenticulae) refers to a small, lenticular-shaped leaf or a lobe of a leaf, especially in ferns and cycads. It can also refer to a small, optical lens or an oculus lens, which is a cylindrical or lentiform shape. In astronomy, lenticulae are small, lens-like objects or tidal tail structures that can be found in the vicinity of galaxies or other celestial bodies.
Lenticulae
Lenticulae is the plural form of the word "lenticule", which refers to a small, rounded or lens-shaped structure, often in medicine. In the context of ophthalmology, a lenticule is a small, transparent, and dome-shaped structure found in the eye, specifically in the center of the lens. It is responsible for helping to focus light onto the retina. In a broader sense, lenticulae can also refer to small, rounded formations found in various natural environments, such as rocks or soil.
Lenticular
A lenticular is a type of cloud or optical phenomenon that has a distinctive, heterogeneous shape, characterized by rounded masses or wisps of cloud that are often irregular and have a rough, wavy or lumpy appearance.
Lenticules
Lenticules are small, rounded or oval-shaped pieces of tissue that are embedded in the inner surface of the cornea, the clear part at the front of the eye. They are a normal part of the anatomy of the cornea and are often visible through an optical instrument such as a microscope or ophthalmoscope.
Lenticulostriate
Lenticulostriate refers to a part of the brain's blood vessels. Specifically, it is a type of branch of the middle cerebral artery that supplies blood to the lentiform nucleus and the caudate nucleus, which are both parts of the basal ganglia, a group of structures involved in movement control, cognition, and emotion regulation. The lenticulostriate arteries play a crucial role in supplying oxygenated blood to these critical brain areas, and their damage or blockage can lead to various neurological and cognitive disorders.
Lentiform
Lentiform refers to a shape that is roughly lens-like or lentil-like in form, typically referring to a part of the brain, in this case the lentiform nucleus, which is a structure in the brain that plays a crucial role inmotor function and speech.
