• A Closer Look at the Symptoms of Macular Degeneration

    In its early stages, age-related macular degeneration is usually hard to detect. For most people, the first sign of macular degeneration is noticing distortion when looking at straight lines, which can gradually lead to loss of central vision. In addition, blurry areas or white out may begin to appear in the center of someone’s vision.

    Generally, people over the age 45 should schedule a complete eye exam and follow-up exam every two to four years. During this exam, the ophthalmologist can screen for early signs of macular degeneration. People who have already been diagnosed with macular degeneration should monitor their vision each day, notifying their ophthalmologist when different symptoms appear or worsen. For example, when someone’s central vision becomes distorted or his or her color perception changes, he or she should contact an ophthalmologist.

  • Deciding Whether LASIK Eye Surgery Is Right for Your Needs

    Eye Surgery

    Even though LASIK eye surgery can eliminate your need for wearing eyeglasses or contact lenses, the procedure does come with some risks. For example, if you suffer from presbyopia, LASIK surgery can help you achieve clear distance vision, but it can also impair your ability to see nearby objects. Generally, LASIK eye surgery is most appropriate if you have a moderate degree of nearsightedness, farsightedness, or astigmatism.


    In order to be a good candidate for LASIK eye surgery, you need to be at least 18 years old with no history of corneal disease. The procedure can help correct nearsightedness, a condition in which you are able to see nearby objects clearly, but far-away objects appear blurry. This condition occurs if your eyeball is too long or if the cornea has too much of a curvature. If you suffer from a moderate degree of nearsightedness, an ophthalmologist can use LASIK eye surgery to reshape the cornea.


    Also known as hyperopia, farsightedness is a condition in which you are able to see distant objects clearly, but can’t properly focus nearby objects. This is the result of the eyeball being too short or the cornea not having enough curvature to correctly focus incoming light. LASIK eye surgery can help reshape your cornea , so that it has the optimal curve to allow light to correctly focus.


    Astigmatism occurs if your eyes aren’t completely round. As light enters your eyes, it is refracted unevenly, which means only one part of an object can focus at a time. This causes distant objects to appear blurry and wavy. If your eyes are healthy and free of retinal problems, then LASIK eye surgery can refocus your corneas, so that light is distributed evenly and objects focus clearly.

    The best way to determine whether or not you are a good candidate for LASIK eye surgery is by meeting with an ophthalmologist.

  • Reviewing the Common Indications of Age Related Macular Degeneration

    Age-related macular degeneration is an eye condition that affects the cone cells in the retina, which are responsible for central and colored vision. As a result, the initial symptoms of macular degeneration often relate to a person’s central vision. The most common symptoms associated with age related macular degeneration are blurred vision and difficulty distinguishing small details.

    As this video explains, macular degeneration frequently develops gradually. This means that people need to pay attention to subtle symptoms, like distortion in everyday objects and tasks becoming increasingly more difficult. This video provides an illustration of what everyday scenes look like with clear vision and with early signs of macular degeneration.

    If you are having difficulty with your vision, schedule a consultation with Dr. Mark Hornfeld of New York . You can reach our office by calling (646) 502-4142.

  • What Is Color Blindness?

    Color blindness is a condition in which someone has difficulty distinguishing red, green, blue, or a mix of these three colors. It’s very rare for someone with color blindness to see no color at all. Even though people with color blindness can still see, the condition makes it harder for them to learn how to read or pursue certain careers.

    Most people with color vision problems inherit them genetically, so they are present at birth. Usually, there are three types of cone cells in the eye. Each type of cone cell senses either red, green, or blue light. When the cone cells sense different levels of these three basic colors, it allows the person to distinguish between colors in their day-to-day environments. Someone who inherits color blindness is missing one of these three types of cone cells, so he or she has difficulty seeing one of these three basic colors. Even though most people inherit color blindness, aging, eye injury, and conditions like glaucoma and cataracts can all lead to the development of color blindness.
