An eye exam that includes a complete history of your overall health and your eye health can help your doctor diagnose the cause of your dry eyes. A test to measure the volume of your tears. Your doctor may measure your tear production using the Schirmer test. In this test, blotting strips of paper are placed under your lower eyelids. The eye is an organ that receives light and visual images. Non-image forming eyes (also called direction eyes) are found among worms, mollusks, cnidarians, echinoderms, and other invertebrates. Image-forming eyes are found in certain mollusks, most arthropods, and nearly all vertebrates. Aye-ayes are dark brown or black and are distinguished by a bushy tail that is larger than their body. They also feature big eyes, slender fingers, and large, sensitive ears. Aye-ayes have pointed.

Wikimedia Commons Wikiversity. The tear glands lacrimal glands , located above each eyeball, continuously supply tear fluid that's wiped across the surface of your eye each time you blink your eyes.
Excess fluid drains through the tear ducts into the nose. Dry eyes are caused by a variety of reasons that disrupt the healthy tear film.
Your tear film has three layers: fatty oils, aqueous fluid and mucus. This combination normally keeps the surface of your eyes lubricated, smooth and clear.
Problems with any of these layers can cause dry eyes. Reasons for tear film dysfunction are many, including hormone changes, autoimmune disease, inflamed eyelid glands or allergic eye disease.
For some people, the cause of dry eyes is decreased tear production or increased tear evaporation. Welcome to NASA's Eyes, a way for you to learn about your home planet, our solar system, the universe beyond and the spacecraft exploring them.

The visual fields of many organisms, especially predators, involve large areas of binocular vision to improve depth perception. In other organisms, eyes are located so as to maximise the field of view, such as in rabbits and horses , which have monocular vision.
The cone cells for colour and the rod cells for low-light contrasts in the retina detect and convert light into neural signals for vision.
The visual signals are then transmitted to the brain via the optic nerve. Such eyes are typically roughly spherical, filled with a transparent gel-like substance called the vitreous humour , with a focusing lens and often an iris ; the relaxing or tightening of the muscles around the iris change the size of the pupil , thereby regulating the amount of light that enters the eye,  and reducing aberrations when there is enough light.
Compound eyes are found among the arthropods and are composed of many simple facets which, depending on the details of anatomy, may give either a single pixelated image or multiple images, per eye.
Each sensor has its own lens and photosensitive cell s. Compound eyes are very sensitive to motion. Some arthropods, including many Strepsiptera , have compound eyes of only a few facets, each with a retina capable of creating an image, creating vision.
With each eye viewing a different thing, a fused image from all the eyes is produced in the brain, providing very different, high-resolution images.
Possessing detailed hyperspectral colour vision, the Mantis shrimp has been reported to have the world's most complex colour vision system.
They used clear calcite crystals to form the lenses of their eyes. In this, they differ from most other arthropods, which have soft eyes. The number of lenses in such an eye varied; however, some trilobites had only one, and some had thousands of lenses in one eye.
In contrast to compound eyes, simple eyes are those that have a single lens. For example, jumping spiders have a large pair of simple eyes with a narrow field of view , supported by an array of other, smaller eyes for peripheral vision.
Some insect larvae , like caterpillars , have a different type of simple eye stemmata which usually provides only a rough image, but as in sawfly larvae can possess resolving powers of 4 degrees of arc, be polarization-sensitive and capable of increasing its absolute sensitivity at night by a factor of 1, or more.
They do have photosensitive cells, but no lens and no other means of projecting an image onto these cells. They can distinguish between light and dark, but no more.
This enables snails to keep out of direct sunlight. In organisms dwelling near deep-sea vents , compound eyes have been secondarily simplified and adapted to see the infra-red light produced by the hot vents—in this way the bearers can avoid being boiled alive.
There are ten different eye layouts—indeed every technological method of capturing an optical image commonly used by human beings, with the exceptions of zoom and Fresnel lenses , occur in nature.
Indeed, any eye type can be adapted for almost any behaviour or environment. Also, superposition eyes can achieve greater sensitivity than apposition eyes , so are better suited to dark-dwelling creatures.
These two groups are not monophyletic; the cnidaria also possess cilliated cells,  and some gastropods ,  as well as some annelids possess both.
Some organisms have photosensitive cells that do nothing but detect whether the surroundings are light or dark , which is sufficient for the entrainment of circadian rhythms.
These are not considered eyes because they lack enough structure to be considered an organ, and do not produce an image.
Simple eyes are rather ubiquitous, and lens-bearing eyes have evolved at least seven times in vertebrates , cephalopods , annelids , crustaceans and cubozoa.
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 eye-spot, to allow the organism to deduce the angle of incoming light.
Pit vipers have developed pits that function as eyes by sensing thermal infra-red radiation, in addition to their optical wavelength eyes like those of other vertebrates see infrared sensing in snakes.
However, pit organs are fitted with receptors rather different to photoreceptors, namely a specific transient receptor potential channel TRP channels called TRPV1.
The main difference is that photoreceptors are G-protein coupled receptors but TRP are ion channels. The resolution of pit eyes can be greatly improved by incorporating a material with a higher refractive index to form a lens, which may greatly reduce the blur radius encountered—hence increasing the resolution obtainable.
A far sharper image can be obtained using materials with a high refractive index, decreasing to the edges; this decreases the focal length and thus allows a sharp image to form on the retina.
Heterogeneous eyes have evolved at least nine times: four or more times in gastropods , once in the copepods , once in the annelids , once in the cephalopods ,  and once in the chitons , which have aragonite lenses.
This eye creates an image that is sharp enough that motion of the eye can cause significant blurring. To minimise the effect of eye motion while the animal moves, most such eyes have stabilising eye muscles.

Typically, watery eyes are temporary and resolve on their own when the cause is addressed or your eyes have healed. However, in some cases, the condition may persist.
The reason for your dry eyes will determine the best treatment. You should contact a physician or eye doctor if you have excessive or prolonged tearing and any of the following symptoms:.
In most cases, watery eyes will clear up without treatment. If not, your physician or eye doctor will perform an eye exam or a physical.

Non-image forming eyes (also called direction eyes) are found among worms, mollusks, cnidarians, echinoderms, and other invertebrates. Image-forming eyes are found in certain mollusks, most arthropods, and nearly all vertebrates. The eye doctor might call this computer vision syndrome or digital eye strain. It affects most people who use one. Some estimates say computer-related eye symptoms may be responsible for up to 6/6/ · The reason for your dry eyes will determine the best treatment.
