Eye Freckle And Eye Doctors Questions? Congenital hypertrophy of the retinal pigmented epithelium (also known as halo nevus) is a pigmented, well demarcated dark spot inside the back of your eye on your retina. Though size varies, it is convenient to think of it as about equivalent to the top of an eraser on a pencil.

Eyepatch An eyepatch or eye pad is a small patch that is worn in front of one eye. It may be a cloth patch attached around the head by an elastic band or by a string, an adhesive bandage, or a plastic device which is clipped to a pair of glasses. It is often worn by people to cover a lost or injured eye, but it also has a therapeutic use in children for the treatment of amblyopia. (See orthoptics and vision therapy.) Eyepatches used to block light while sleeping are referred to as a sleep mask.

Red dot sight A red dot sight is a common classification for a type of non-magnifying reflector (or reflex) sight for firearms, and other devices that require aiming, that gives the user an aimpoint in the form of an illuminated red dot.ed dot sights place the target and the reticle on nearly the same optical plane, allowing a single point of focus. This makes them fast acquisition and easy to use sights, allowing the user to keep their attention on the field of view in front of them.

Eye Pit eyes, also known as stemma, are eye-spots which may be set into a pit to reduce the angles of light that enters and affects the eyespot, to allow the organism to deduce the angle of incoming light. Found in about 85% of phyla, these basic forms were probably the precursors to more advanced types of simple eye. compound eye may consist of thousands of individual photoreceptor units or ommatidia (ommatidium, singular). The image perceived is a combination of inputs from the numerous ommatidia (individual eye units), which are located on a convex surface, thus pointing in slightly different directions.

What is the dot over the letter 'i' called? 1 vote Vote for this answer. Oxford English Dictionnary confirms 'tittle' although any sign, such as the Spanish tilde (same origin) or the French accents or German Umlauts, part of a letter can be considered a tittle. The dot is therefore a tittle, although a tittle is not necessarily that dot.

- Strabismus or tropia are the medical terms for eye conditions commonly called by various names: eye turns, crossed eyes, cross-eyed, wall-eyes, wandering eyes, deviating eye, etc.Strabismus is not the same condition as  lazy eye  (amblyopia).ye doctors generally look for the presence of a strabismus when looking at distance (20 feet or more); at near (16 inches for an adult and 13 inches for a child); and the lateral and vertical directions (up, down, left, or right). When the eye turn occurs all of the time, it is called constant strabismus.

Vision Once the light hits the eye it goes through a variety of structures. Take a look at the diagram below. The white part of our eye is called the cornea and basically protects and helps reflect light. The light goes through a hole in our eye called a pupil.

About the eye The iris is the ring of pigmented tissue surrounding the pupil that varies in color. The iris opens and closes to control the amount of light entering the eye through the pupil. The pupil is the opening in the center of the iris where light enters the eye. When looking at the eye, the pupil appears black. In dim light, the opening in the center of the iris expands to allow more light to enter the pupil.

Timeline Squiggly Lines in the Eyes They are known as floaters or benign floaters or vitreous floaters: A blurry spot that seems to drift in front of the eyes but does not block vision. The blur is the result of debris from the vitreous of the eye casting a shadow on the retina. We call them Squiggly Lines! More info below.

- The eye is a slightly asymmetrical globe, about an inch in diameter. Just behind the iris and pupil lies the lens, which helps to focus light on the back of the eye. Most of the eye is filled with a clear gel called the vitreous. Light projects through the pupil and the lens to the back of the eye.

- The white part of the eye is a tough outer layer called the sclera. The sclera protects the inside of the eye and helps the eye keep its structure. The colored part of the eye is called the iris. This portion of the eye is what controls the amount of light that is let into the inner eye.

A Picture of the Eye • The pupil (the black circular opening in the iris that lets light in) • The sclera (the white part) • The conjunctiva (a thin layer of tissue covering the front of the eye, except the cornea) Just behind the iris and pupil lies the lens, which helps to focus light on the back of the eye. Most of the eye is filled with a clear gel called the vitreous. Light projects through the pupil and the lens to the back of the eye. The inside lining of the eye is covered by special light-sensing cells that are collectively called the retina. The retina converts light into electrical impulses. Behind the eye, the optic nerve carries these impulses to the brain.

The Eye This article gives you a brief overview about the essentials of the eye. The eye ball lies in the orbit, a bony cavity in the skull. The retrobulbar fat (corpus adiposum orbitae) is a fatty tissue that lines the orbit from the inside and contains the vessels and nerves. The eye ball consists of the eye layers, the lens and the chambers. One of the main eye layers are the sclera and the cornea. The sclera represents the white of the eye. It is covered by the conjunctiva, a transparent mucous membrane which is important for the distribution of the tear film during the eye blink.

- Matter floating inside the eye moves into the line of sight and appears as specks floating in front of our eyes. Floaters (also called “spots”) are tiny clumps of gel or other semi-transparent matter that drift freely inside the vitreous, the jelly-like fluid that fills the inside of your eyes.

Pupil The pupil is a hole located in the center of the iris of the eye that allows light to strike the retina.It appears black because light rays entering the pupil are either absorbed by the tissues inside the eye directly, or absorbed after diffuse reflections within the eye that mostly miss exiting the narrow pupil.he iris is a contractile structure, consisting mainly of smooth muscle, surrounding the pupil. Light enters the eye through the pupil, and the iris regulates the amount of light by controlling the size of the pupil.

What Is the Red Spot on My Eye? The red spot you see is most likely a small blood vessel that burst open during the night. In medical terms, it is called a subconjunctival hemorrhage. Small blood vessels lie underneath the conjunctiva, the clear coating that covers the sclera, the white part of the eye.

- I can! A few years ago I got gasoline in my eye (I still haven't really figured that out...) and the doctor used the same setup. I can't really figure out what to call it to get you an image from the Google, but it's essentially a round, large contact lens that sits on your eye underneath the lids.

Eye health guide The eye is a slightly asymmetrical globe, about an inch in diameter. Just behind the iris and pupil lies the lens, which helps to focus light on the back of the eye. Most of the eye is filled with a clear gel called the vitreous. Light projects through the pupil and the lens to the back of the eye. The inside lining of the eye is covered by special light-sensing cells that are collectively called the retina. The retina converts light into electrical impulses. Behind the eye, the optic nerve carries these impulses to the brain. The macula is a small extra-sensitive area within the retina that gives central vision. It is located in the center of the retina and contains the fovea, a small depression or pit at the center of the macula that gives the clearest vision. Eye color is created by the amount and type of pigment in the iris.

- The eye with the cataract(s) has a cloudiness of the lens of the eye. The purpose of the lens is to focus the rays of light so that they may form an image on the retina. If the lens becomes cloudy then less light can enter the eye and the sight will slowly diminish as the cataract becomes larger.iberians can even have parti eyes. This means that part of their eye is one color with a splash or more of another color! These siberian eyes are amazing! They can have two different colored eyes. For example, they may have one brown eye and one blue eye.

Spots and Flashes When the spots appear rather fuzzy and seem to be strung together with a web-like thread, they are called floaters. Flashes are bright points of light that literally flash into the field of vision when the eyelids are open or closed. They usually appear as tiny dashes forming either an oval or a circle.

- What Is It? A black eye, sometimes called a shiner, is a bruise around the eye. When an object strikes the eye, the force of the impact breaks delicate blood vessels in the eyelids and surrounding tissues. Blood collects under the skin, and causes black or blue discoloration in the eyelids and around the eye socket.
