According to Prevent Blindness America, more than 700,000 Americans injure their eyes while at work, 125,000 injure their eyes at home, and 40,000 American children and adults suffer eye injuries while playing sports. Most of these injuries could have been prevented by the use of protective safety goggles. Safety eyewear must conform to a higher standard of impact resistance than regular eyeglasses. This higher standard applies to both the lenses and the frames of safety glasses and goggles. Safety glasses may have prescription lenses or non-prescription lenses. Regardless of their size or the durability of the frame and lenses, regular … Read more…
A fingerprint has 40 different unique characteristics. An iris has 256, hence the growing use of iris scans for security purposes.
Glaucoma occurs when there is an increase of fluid production or a decrease in fluid drainage within the front part of the eye. Over time, as the pressure within the eye remains elevated or peaks at different times of the day, the optic nerve fibers are destroyed and peripheral (side) vision is lost. If not treated adequately, an elevated pressure can also cause irreversible loss of central vision. Aqueous humor flows out of the eye through the Trabecular Meshwork near the outer edge of the iris. Over time, in certain individuals with glaucoma, that trabecular meshwork becomes blocked and the … Read more…
The IntraLase Method is a 100% blade-free technique used to perform the critical first step in the LASIK procedure: creating the corneal flap. The creation of the corneal flap prepares the eye for the second step of the LASIK procedure, where the VISX STAR 4 IR™ Excimer laser is used on the inner cornea to correct vision. IntraLase can be an important option for patients with thin corneas or who have a corneal epithelial dystrophy. The IntraLase Method uses tiny, rapid pulses of laser light to create your corneal flap—instead of using a metal blade—during the first step of LASIK. … Read more…
If you’re shortsighted, your eyeball is longer than normal. If you’re farsighted, it’s shorter than average.
The technique of cataract surgery involves removing the cloudy portion of the eye’s lens while leaving the clear outer membrane, or capsule, to hold the new intraocular lens in place. This outer membrane contains cells that may continue to produce lens fibers. These fibers cannot be laid down in an organized manner and will form little beads or “pearls” on the lens capsule, forming a secondary membrane. When these pearls accumulate in the pupil, they can cause a blurring of vision similar to that which one experiences with a cataract. This occurs approximately 30-40% of the time and can appear … Read more…
Amblyopia, or a Lazy Eye, is the loss or lack of development of central vision in one eye that is not correctable with lenses. It can result from a failure to use both eyes together. Lazy eye is often associated with crossed-eyes or a large difference in the degree of nearsightedness or farsightedness between the two eyes. It usually develops before the age of 6, and it does not affect peripheral vision. For this reason, early diagnosis is critical and increases the chance for a complete recovery. Symptoms of Amblyopia Symptoms of Amblyopia are not always so obvious. These may … Read more…
The “visual centers” in your brain are actually located at the lower back part of your head. That’s why if you were to fall very hard on the back of your head, it’s possible to go blind temporarily. The optic nerve begins at the back of the eye and, through a series of connections, relays the visual images to the occipital cortex in the very back of the brain.
A Pterygium is a growth that can grow across the eye. Do you know why it is called pterygium? It is because ptery is the Latin root for “wing”. Since the growth looks like a wing growing across the eye they called it a pterygium.
WHAT IS KERATOCONUS? Keratoconus is a thinning disorder of the cornea that causes visual distortion. Common symptoms include: ghosting, multiple images, glare, halos, starburst around lights, blurred vision and eye irritation with excessive eye rubbing. The earliest signs of this condition are usually blurred vision and frequent changes in the patient’s eye glass prescription. Sometimes vision cannot even be corrected with glasses. Symptoms typically begin in late teenage years or early twenties, but can start at any time. Keratoconus requires a diagnosis from a doctor trained to recognize the symptoms. Keratoconus can usually be diagnosed with a slit-lamp examination. Classic … Read more…
