Similar to a bruise under the skin, a subconjunctival hemorrhage happens when a small blood vessel located between the sclera (white portion of an eye) and the conjunctiva (lining on the surface of an eye) breaks and covers the sclera with blood. Unlike broken blood vessels located under the skin which

Eye movement refers to the voluntary and involuntary movements of the eyes that assist with obtaining, fixating and following visual stimuli. The eyes are each connected to a system of six muscles. Light is sensed by the retina, which is a type of tissue that contains cells known as photoreceptors. These

The eyes have a focusing system called accommodation; it allows for visual clarity. The system is rested when you look at an object that is far away and is not forced to strain like it would if the target were close. In normal circumstances, the eyes are able to effortlessly transition between objects

Each eye picks up a slightly different image, but through a process called fusion, the brain blends the images together to make one three-dimensional picture. Good eye coordination is needed, however, and allows the eyes to sustain proper alignment so that they can focus on practically the same image,

Visual perception refers to a set of skills used to collect and interpret visual information taken in from our environment. The visual information gathered is combined with our other senses, allowing us to derive meaning from what we see. Through the process of merging visual data with our other senses,

Loss of eyesight and macular degeneration are typically associated with aging. Stargardt disease, however, an inherited form of macular degeneration, commonly affects children and young adults. Also referred to as Stargardt macular dystrophy (SMD) or flavimaculatus, the term Stargardt disease refers

The term retinitis pigmentosa (RP) refers to a set of degenerative genetic diseases that gradually kill off the light-sensing cells (rods and cones) of the retina, eventually causing blindness. It is a relatively rare genetic disorder, affecting only 1 in 4,000 people. Retinitis pigmentosa can be difficult

You may have heard of macular degeneration, an age-related condition in which people suffer permanent vision loss due to damage in a part of the retina called macula.

If you find yourself experiencing blurred or distorted vision that seems to get worse year after year, you may suffer from an irregularity of the cornea known as keratoconus.

Cytomegalovirus (CMV) retinitis is a serious disease causing compromised vision and ultimately a total loss of vision. CMV retinitis is typically associated with Acquired Immunodeficiency Syndrome (AIDS). In the early days of the AIDS epidemic, nearly one-quarter of all individuals diagnosed with late-stage

Bifocal contact lenses are a type of contact lens that combine two different prescriptions in the same lens. One component corrects nearsightedness and the other prescription addresses farsightedness or farsightedness. Several types of bifocal contacts are available; your eye care provider can help you

Can I wear contact lenses? Most people are able to wear contact lenses safely and comfortably. There are contact lenses that correct for nearsightedness, farsightedness, astigmatism, and other vision problems. An optometry exam can determine what lenses are appropriate for you. Are contact lenses safe

Characterized by a yellowish raised part of the scleral conjunctiva (the lining of the white part of the eye), a pinguecula usually develops near the cornea (colored part of the eye), but does not extend past it. Similar to a callus on the skin, changes in tissues lead to the buildup of calcium, fat,

One of the most important reasons for regular examinations by your eye care provider is evaluate for the development of macular degeneration. According to the Bright Focus™ Foundation, this condition is the primary cause of loss of vision and blindness in older individuals ages 60 and above and is
