Product Information

The eyelid also has great reflexes, which are automatic body responses, that protect the eye. When you step into bright light, for example, the eyelids squeeze together tightly to protect your eyes until they can adjust to the light. And if you flutter your fingers close (but not too close!) to your friend's eyes, you'll be sure to see your friend's eyes blink. Your friend's eyelids shut automatically to protect the eye from possible danger. And speaking of fluttering, don't forget eyelashes. They work with the eyelids to keep dirt and other unwanted stuff out of your eyes. What's the Sclera? The human eye is a sensory organ, part of the sensory nervous system, that reacts to visible light and allows humans to use visual information for various purposes including seeing things, keeping balance, and maintaining circadian rhythm.

Fovea: forms a small indentation at the centre of the macula and is the area with the greatest concentration of cone cells. When the eye is directed at an object, the part of the image that is focused on the fovea is the image most accurately registered by the brain.

Amblyopia: Often called lazy eye, this condition starts in childhood. One eye sees better than the other, so your brain favors that eye. The weaker eye, which may or may not wander, is called the "lazy eye." Dry eye: Either your eyes don’t produce enough tears, or the tears are of poor quality. Most commonly due to aging but medical problems like lupus, scleroderma, and Sjogren's syndrome can be to blame. Changing the curvature of the lens is carried out by the ciliary muscles surrounding the lens; this process is known as "accommodation". Accommodation narrows the inner diameter of the ciliary body, which actually relaxes the fibers of the suspensory ligament attached to the periphery of the lens, and also allows the lens to relax into a more convex, or globular, shape. A more convex lens refracts light more strongly and focuses divergent light rays from near objects onto the retina, allowing closer objects to be brought into better focus.

Although it may be hard to pronounce, phytosphingosine is a naturally-occurring, safe ingredient that is quite beneficial to the skin. It is one type of lipid that makes up of the skin’s natural lipid barrier, which also contains ceramides, cholesterol, and fatty acids. Without these essential lipids, the barrier is weakened. A weak or damaged barrier allows moisture to escape and harmful things like allergens, bacteria, and irritants to pass through into the deeper layers of skin. Ultimately, this can lead to the formation of skin conditions such as dryness, irritation, sensitive skin, and even signs of aging. Using phytosphingosine as a key ingredient in Clinique All About Eyes is one way to prevent these problems by strengthening the skin’s barrier.

The lids also contain smooth (involuntary) muscle fibres that are activated by the sympathetic division of the autonomic system and tend to widen the palpebral fissure (the eye opening) by elevation of the upper, and depression of the lower, lid.

Bright flashes of light in your vision, a sudden increase in floaters, or a loss of vision that looks like a dark curtain or wall covering part of your vision. Cunningham, Emmett T.; Riordan-Eva, Paul (2011-05-17). Vaughan & Asbury's General Ophthalmology (18thed.). New York: McGraw-Hill Medical. ISBN 978-0-07-163420-5.In addition to the muscles already described, other facial muscles often cooperate in the act of lid closure or opening. Thus, the corrugator supercilii muscles pull the eyebrows toward the bridge of the nose, making a projecting “roof” over the medial angle of the eye and producing characteristic furrows in the forehead; the roof is used primarily to protect the eye from the glare of the sun. The pyramidalis, or procerus, muscles occupy the bridge of the nose; they arise from the lower portion of the nasal bones and are attached to the skin of the lower part of the forehead on either side of the midline; they pull the skin into transverse furrows. In lid opening, the frontalis muscle, arising high on the forehead, midway between the coronal suture, a seam across the top of the skull, and the orbital margin, is attached to the skin of the eyebrows. Contraction therefore causes the eyebrows to rise and opposes the action of the orbital portion of the orbicularis; the muscle is especially used when one gazes upward. It is also brought into action when vision is rendered difficult either by distance or the absence of sufficient light. The skin Tears also keep your eye from drying out. Then the fluid drains out of your eye by going into the lacrimal duct (this is also called the tear duct). You can see the opening of your tear duct if you very gently pull down the inside corner of your eye. When you see a tiny little hole, you've found the tear duct. Strabismus: When the eyes don’t point in the same direction. Your brain may favor one eye. If it happens to a kid, it can decrease vision in the other eye. This condition is called amblyopia.
