Presbyopia is the gradual decline in close vision that occurs with age. The condition occurs as the lens in the eye stiffens and loses its flexibility, thereby impairing its ability to focus at images or objects up close. While multifocal prescription glasses, such as bifocals, are one possible treatment

Laser-assisted in-situ keratomileusis, or LASIK, is the most common type of refractive surgery. If the curvature of your cornea deviates from the ideal curvature, light entering your eye will bend (refract) incorrectly. This is known as a refractive error and can cause vision problems. For many patients,

When the cornea is misshapen, light bends (refracts) incorrectly, leading to vision problems. Refractive surgeries aim to reshape the cornea, thereby improving vision. LASIK is one of the most popular types of refractive surgeries. However, not everyone is an appropriate candidate for LASIK. Fortunately,

Corneal transplantation is a surgical procedure to replace part of a damaged or diseased cornea with corneal tissue from a donor. The cornea is the transparent, dome-shaped surface on the front of the eye. It plays a large part in vision by helping to focus light onto the retina. Reasons for Corneal

Intacs Intacs, or intracorneal ring segments (ICRS), is a non-laser treatment for mild nearsightedness. It can also be used to treat the astigmatism and nearsightedness that occurs with keratoconus, one type of corneal disorder. How Intacs Works Intacs is a pair of crescent-shaped plastic devices

Glaucoma is a condition characterized by excessive pressure in the eye, or intraocular pressure. This irregularly high pressure is due to a buildup of fluid in the eye. As intraocular pressure increases, it can compress the eye’s optic nerve, eventually leading to vision loss. Around 3 million people

The iStent Trabecular Micro-Bypass is a surgical device that is available for use in treating patients with mild-to-moderate open-angle glaucoma. Glaucoma is characterized by an excessive accumulation of fluid inside the eye, which leads to an increase in the inner eye pressure (intraocular pressure).

While keratoconus can happen at any stage of life, young people between the ages of 10 and 25 are most likely to develop this disorder. For individuals with keratoconus, their cornea, the clear layer in the front of your eye, gradually thins and begins to bulge outward. Keratoconus typically causes nearsightedness

Pterygium is characterized by a pink tissue growth on the sclera (the white part of the eye), which seems to be the result of chronic exposure to ultraviolet light. In fact, because many surfers suffer from pterygium, the condition is often called surfer’s eye. Pterygium is not cancerous and may continue

If your vision is blurred due to cataracts and you are pursuing surgical intervention to correct the problem, you are likely considering which intraocular lens (IOL) to choose, to restore your vision after cataract surgery. There are a variety of IOL options to choose from. Your ophthalmologist can help

In order for your eyes to focus normally, six muscles around each eye must work together. When your two eyes see different images, your brain tends to favor the stronger eye. This means the weak eye gets weaker, resulting in amblyopia, or “lazy eye.” Risk factors for developing strabismus may include

More than 300,000 sports-related concussions occur each year, according to research. Many more concussions result from motor vehicle accidents, falls, and other non-sports related incidents. In addition to causing cognitive difficulties, concussions may result in a cluster of problems called post-concussive

The cognitive differences of special needs children and adults are well-documented, but vision issues often receive less attention. People with special needs have the same range of vision issues as their neurotypical counterparts; however, these vision problems occur at a much higher rate in special

Accurate vision involves much more than good eye health. The brain integrates signals from the eyes with information from the motor, balance, and auditory systems to create an accurate view of the world. Following traumatic injury, one or more components of this complex system may be damaged. Receiving

Amblyopia, commonly called lazy eye, refers to the improper development or significant loss of vision in an eye. It occurs when the brain does not acknowledge the images seen by the amblyopic eye. Amblyopia Causes Amblyopia occurs when an individual cannot use binocular vision (both eyes working together)

There are many potential causes for blurry eyes. The answer to why you have blurry vision is best answered by your eye care professional, who can offer diagnosis and prompt treatment so that your vision does not get worse. Some conditions that cause blurry vision are easy to treat, but others require

Double vision, also known as “seeing double” or the medical term diplopia, is the perception of two images of a single object. This occurs when two nonmatching images are sent to the part of the brain that processes visual input. Over time, the brain eventually begins to compensate for this misinformation

In an ideal world, everyone would have perfectly-shaped eyes. The reality, however, is that practically every eye has some form of aberration somewhere in it. These aberrations may or may not cause vision problems, but don't be too surprised if your eye doctor informs you that you are having difficulties

An eye condition affecting roughly 50 percent of individuals who need glasses, hyperopia (commonly called farsightedness) is characterized by difficulty focusing on nearby objects while being able to see objects at a distance properly. Hyperopia occurs when your eyeball is too short or when your cornea

Myopia, commonly called nearsightedness, is a refractive error of the eye, meaning that the shape of the eye or its cornea improperly bends light as it enters the eye. This hinders your ability to focus. Myopia is the most common refractive error of the eyes, and is caused by several factors including

Glare and halos are both eye symptoms that some people experience around bright lights. Halos show up as bright circles around a light source. Glare is light that interferes with your vision, making it difficult to see or sometimes making your eyes water. These symptoms can show up at any time of the

Every morning, we open our eyes and become immersed in a wealth of visual information.
