University of Texas at Austin researchers have discovered how to extract and use information in an individual image to determine how far objects are from the focus distance, a feat only accomplished by human and animal visual systems until now.

Posted by Bharat (#1) 4631 days ago (Editorial)
Amid reports of severe eye pain and hazy vision, CooperVision "continues" its recall of 600,000 Avaira Toric contact lenses. The original three-paragraph recall notice was issued on Aug. 19. It suggested that relatively few contact lenses were involved and offered no specific information to consumers or to retailers. The FDA confirms that it exchanged letters with CooperVision over the recall, al
Causes of Eye Allergies
Posted by Bharat (#1) 4613 days ago (Editorial)
Eye allergies often affect the conjunctiva, a clear layer of skin overlying the eyes. This clear layer of skin is the same type of skin that lines the inside surface of the nose. Because these two areas are so similar, the same allergens (substances that induce an allergic reaction) can trigger the same allergic response in both areas.
Common eye allergy triggers include: Pollen, Grass, Weeds,

What Is a Macular Hole?
Posted by Bharat (#1) 4599 days ago (Editorial)
The macula is a very small area at the center of the retina — a thin layer of light-sensitive tissue that lines the back of the eye. Light rays are focused onto the retina, where they are transmitted to the brain and interpreted as the images you see. It is the macula that is responsible for your pinpoint vision, allowing you to read, sew or recognize a face. As we grow older, the thick vitreous
What is Presbyopia?
Posted by Bharat (#1) 4581 days ago (Editorial)
Presbyopia means "age of sight." It is not the same thing as farsightedness. It is a gradual loss of accommodation - the ability of the eye to adjust in order to see clearly objects at different distances. To accommodate this ability, the naturally elastic lens of the eye changes in shape and thereby adjusts its focusing power. Loss of accommodation occurs gradually throughout life. As the lens o
Childhood Glaucoma
Posted by Bharat (#1) 4574 days ago (Editorial)
Childhood glaucoma — also referred to as congenital glaucoma, pediatric, or infantile glaucoma — occurs in babies and young children. It is usually diagnosed within the first year of life.This is a rare condition that may be inherited, caused by incorrect development of the eye’s drainage system before birth. This leads to increased intraocular pressure, which in turn damages the optic nerve.Symp
Scientists Make Advances In Neuroscience And Vision Research
Posted by Bharat (#1) 4567 days ago (Editorial)
Thanks to a new study of the retina, scientists at UC Santa Barbara have developed a greater understanding of how the nervous system becomes wired during early development. The findings reflect the expansion of developmental neurobiology and vision research at UCSB

Lattice Degeneration
Posted by Bharat (#1) 4546 days ago (Editorial)
Lattice degeneration is a common, atrophic disease of the peripheral retina characterized by oval or linear patches of retinal thinning. The prevalence peaks by the second decade and is believed to be minimally progressive but may be uncommonly complicated by retinal detachment. Learn more about Lattice Degeneration at www. me
