• Symptoms of Glaucoma

    Dr. Mark Hornfeld, Ophthalmologist

    Glaucoma is an eye condition that causes vision loss due to damage to the optic nerve. It is among the most common causes of blindness in the U.S. There are two primary types of glaucoma: primary open-angle and angle-closure. A person with open-angle glaucoma may not realize it until a great deal of damage has already occurred, as the symptoms may not be noticeable at first. When symptoms occur, the sufferer will experience a loss of peripheral vision and later, tunnel vision.

    Angle-closure glaucoma typically has a wider array of symptoms, which may include eye pain, nausea, and vomiting. Seeing halos around light sources and blurred vision are also common. Other symptoms include eye reddening and abrupt visual disturbances.

    Have your ophthalmologist examine your eyes regularly for signs of glaucoma. Prompt treatment is critical for the best results. Call the NYC practice of Dr. Mark Hornfeld at (646) 502-4142 to learn about glaucoma management techniques.

  • Tips for Taking Care of Your New Prescription Eyewear

    Your eyes are two of your most valuable assets, which is why you should support them by taking good care of your prescription eyewear. If you find yourself frequently visiting the ophthalmologist’s office to replace broken frames or missing eyeglasses, it’s time to reassess your storage methods. It’s also a good idea to ask your ophthalmologist whether you’re cleaning your eyeglasses properly. Ophthalmologists recommend scratch-resistant lenses, but these eyeglasses are still prone to scratches if you clean them improperly. Prevent these issues by following these tips for caring for your eyeglasses.

    Keep Them Clean

    Keep your eyeglasses clean to ensure clear, sharp vision. Your ophthalmologist’s office staff might recommend a particular eyeglass cleaner; otherwise, clean the lenses gently under warm, soapy water. Rinse them thoroughly and dry them with a microfiber lens cleaning cloth. Never use any other materials, including paper towels or tissues, as these materials can cause scratches.

    Store Them Properly

    When you’re not wearing your eyeglasses, use a hard-shell case to store them . Avoid using soft cases, as they will make your eyeglasses more vulnerable to damage. If you set your glasses down, fold the frames and position them so that the lenses are facing up. You should never leave your eyeglasses in a hot car. If you’re prone to misplacing your glasses, always keep the case in the same place in your home.

    Adjust Them As Needed

    Eyeglasses are susceptible to becoming misaligned—particularly when they are frequently mishandled. Avoid misalignment by using both of your hands to position your glasses on your nose, and refrain from wearing them on top of your head. If you notice your frames becoming misaligned, bring them to your ophthalmologist’s office for an adjustment.

    The office of Dr. Mark Hornfeld carries a wide array of frames and lenses to suit every need and preference. Call our NYC practice today at (646) 502-4142 or visit our website to learn more. We also offer LASIK surgery, glaucoma treatment, and cataract surgery.

  • Clearing Cataract-Clouded Vision [INFOGRAPHIC]

    The cloudy vision of cataract-compromised eyes is common in people over 40. By the age of 80, 50% of people will have cataracts. Cataracts tend to start out slowly, with vision that is just a little less sharp, but as the cataracts grow, vision becomes more and more impaired. In early stages, most patients can deal with cataracts by changing the prescription for their glasses and contacts, but the only way to stop this lens clouding is to have the cataract surgically removed and an intraocular lens (IOL) implanted in its place. A lens implant specialist in NYC explains everything you need to know about cataracts in this infographic. Please spread the word about this important eye health issue by reposting this information.


  • A Patient’s Guide to Cataracts

    A cataract is an area of cloudiness on the lens of an eye. The eye’s lens is essential for transferring and focusing light rays on the retina in order to produce images. When the lens becomes cloudy, vision is obscured. It’s important to see an ophthalmologist for regular check-ups so he or she can detect these issues early. Keep reading for an overview of cataracts and how they can be treated.

    Possible Causes and Risk Factors

    Cataracts are often the result of the natural aging process. Over the years, the tissue of the lens is susceptible to protein clumping and tinting. Cloudiness can occur because of an injury or a genetic condition. Other risk factors for cataracts include obesity, exposure to ionizing radiation, excessive consumption of alcohol, excessive sunlight exposure, and prolonged use of corticosteroid drugs. Other risk factors may include a previous eye injury or surgery, tobacco use, and high blood pressure.

    Typical Symptoms

    Cataracts develop gradually, so you may not notice symptoms right away. Over time, you might have problems seeing clearly at night, or you might start seeing “halos” around light sources. You might also require more frequent changes in your eyeglass prescription and your vision will become cloudy, dim, or blurred, or your eyes may become more sensitive to light.

    Treatment Options

    If you notice any changes in your vision, see your ophthalmologist right away. If the cataract doesn’t appear to be severe, you might initially try lifestyle modifications, such as wearing anti-glare sunglasses. If your vision is more significantly compromised, you may require cataract surgery, during which your natural lens will be replaced with an intraocular lens implant (IOL).

    If you’ve noticed any possible symptoms of a cataract, schedule an appointment with Dr. Mark Hornfeld. Call our NYC practice at (646) 502-4142 with any questions. Dr. Hornfeld has a wealth of experience successfully performing cataract surgery.

  • Understanding Cataracts

    Cataracts are a common vision problem that ophthalmologists regularly diagnose and treat. But what are they, exactly? You may already know that a cataract interferes with normal vision. It does this by preventing the proper focusing of light rays on the retina due to cloudiness of the lens. When the lens becomes cloudy, it turns yellow.

    Early detection of vision problems is essential, so schedule regular examinations with Dr. Mark Hornfeld of NYC. Call our ophthalmology office today at (646) 502-4142 to learn more.
