    Dry eye syndrome Nobody likes having dry eyes, but luckily your ophthalmologist in New York can help you find relief! Meeting with an eye doctor is the best way to figure out what is causing your dry eyes and how to stop or help the problem. Read about common causes of dry eyes before scheduling an appointment with an eye specialist:

    Getting Older

    Unfortunately, aging is one of the most common causes of dry eyes. People often experience dry eyes as they get older, with some suffering worse than others. Most people aged 65 and older suffer from dry eyes at varying degrees of severity. Artificial tear solutions can provide comfort for patients with mild dry eyes.

    Taking Certain Medications

    If your eyes feel dried out on a regular basis, it might be due to medications you take regularly. There are a variety of medications that affect how the eye produces tears, resulting in dry eyes that can feel itchy and irritated. Medications that cause dry eyes include antidepressants, decongestants, antihistamines, and blood pressure medications. An eye doctor can help you determine if your medications are causing your dry eyes.

    Exposure to Certain Environmental Factors

    Weather conditions and other environmental factors can have a serious impact on eye moisture. If you are regularly exposed to wind or dry weather, you might experience faster tear evaporation that makes eyes feel dry. Smoking or staring at a computer screen for long periods of time can also dry your eyes out, making them feel strained and irritated.

    Suffering from Specific Medical Conditions

    People who suffer from certain medical conditions tend to have a higher risk of suffering from dry eyes, as well. Medical conditions that can have this effect include thyroid problems, diabetes, and rheumatoid arthritis. Conditions that affect the eyelids can also result in dry eyes.

    There are four distinct types of refractive errors that can impair your vision and require you to seek professional treatment from an ophthalmologist like Dr. Mark Hornfeld . These errors can affect persons of all ages and often lead to a number of frustrating conditions associated with focusing. To learn more, take a look at this overview of refractive errors:

    Recognizing the Signs of a Refractive Error

    There are many symptoms of refractive errors that are likely to send you in to your ophthalmologist’s office. These symptoms range based on the specific type of error you may have, but often include headaches, frequent squinting, double vision, halos around lights, and eye strain. Your risk for developing a refractive error increases if you are the child of a parent with any of the four errors featured below.

    Understanding the Four Distinct Types

    In order to understand refractive errors , it’s important to know that there are four distinct types that can alter your vision. Myopia, often called “nearsightedness”, is the result of light focusing in front of instead of on the retina. Hyperopia produces the opposite effect, which is commonly referred to as “farsightedness”. Presbyopia impairs an aged eye’s ability to focus up close. Astigmatism is characterized by blurry vision as a result of light focusing improperly on the retina.

    Treatment Options and Future Prognoses

    An ophthalmologist can treat refractive errors using Lasik surgery, or with eyeglasses or lenses. The former, Lasik surgery, which is essentially a refractive surgery, alters the cornea so that light can focus on the retina more directly. This surgery is permanent and will leave vision improved for the rest of a patient’s lifetime.

    One of the most effective steps that you can take to prevent cataracts from developing is to pay attention to your diet. Surprisingly enough, what you eat from day to day can have a big impact on your vision and overall eye health. Let’s explore the relationship between nutrition and cataracts :

    Antioxidants and Their Link to Eye Health

    In order to understand how nutrition plays a role in the development or advancement of cataracts, it’s important to know that numerous research studies have concluded that antioxidants have a direct impact on eye health. In fact, researchers agree that the more prevalent antioxidants are in a diet, the more likely a person is to experience cataracts for anywhere from three years into the future to ten years.

    Vitamins and a Reduction in Cataract Progression

    The specific varieties of antioxidants that have been proven to reduce the likelihood of cataracts are vitamin C, vitamin E, and beta-carotene. These essential vitamins also offer benefits to those who already have cataracts by reducing the speed at which cataracts progress. This means that by supplementing your diet with antioxidants, you may be able to preserve your vision even if your ophthalmologist has detected cataracts.

    Recommended Foods for Cataract Prevention

    Now that you know how important nutrition is to cataract prevention and cataract control, you may be wondering what foods to add to your diet. Some excellent choices include antioxidant-rich fruits and vegetables, nuts and seeds, fatty fish varieties, and mineral-dense whole grains. If you can’t get enough vitamins in their natural form, then you may want to ask your doctor about adding supplements to your diet.

  • Signs of an Eye Infection When Wearing Contact Lenses

    Using contact lenses comes with many benefits, such as allowing you to not depend on wearing glasses. However, wearing contact lenses can also put you at risk for various eye infections. Even though it is recommended to have an ophthalmologist diagnose a condition, it is important to be able to detect signs of an eye infection on your own.

    Symptoms of an Eye Infection

    One of the main indications of eye infections is general discomfort in the eye. This can include the sensation that something is in your eye, itchiness, or dryness. Beyond general pain and soreness, be sure to look out for any discharge from your eyes. You might see yellow, green, bloody, or watery fluids. Other signs that you may have an eye infection when wearing contact lenses include a sore on your iris, sensitivity to light, or blurred vision.

    Common Eye Infections

    The most common eye infection related to wearing contact lenses is keratitis, an infection of the cornea. This can stem from multiple causes, such as bacteria and fungus. In more serious cases of keratitis, patients’ may need a cornea transplant. Developing good habits and detecting any signs of an eye infection early on can prevent this from happening.

    Habits to Help Prevent Eye Infections

    One of the most critical behaviors to keep in mind when wearing contact lenses is to always wash your hands thoroughly before touching your contacts or your eyes. Doing this simple task helps to prevent a lot of bacteria and microbes from getting in your eye that can lead to eye infections. In addition to this, it is important to not only use fresh contact solution, but to not wear your contact lenses longer than you should.

  • Common Questions About Cataract Surgery

    Cataracts are a natural symptom of aging, but not everyone is familiar with what they are or how they are treated. Since more than half of the US population will have cataracts or undergone cataract surgery by age 80, it is important to know more about what they are and how they are treated. What is a cataract? It occurs when the protein in the lens of your eye clumps together to cloud the lens and make your vision blurry. Fortunately, ophthalmologists can perform simple procedures that easily remedy this common condition.

    Who Benefits from Cataract Surgery?

    In general, those experiencing the common symptoms of cataracts should look into receiving this surgery. These include frequent prescription changes, poor night vision, glare, and cloudy vision. Since these may also be indications of other problems, it is important to verify with your eye-care professional.

    What is Cataract Surgery?

    The most common procedure is phacoemulsification, also called “small incision cataract surgery .” In this process, a device emits ultrasound waves that break up the lens into smaller pieces so it can be suctioned out. It is a painless method that usually lasts under an hour. Extracapsular surgery is another common practice in which the lens is removed in one piece. In either surgery, after it has been removed, you will receive an artificial lens implant that improves your vision.

    What is the Recovery Process like?

    Recovery is usually very fast. It is recommended that you have someone drive you home, but most patients can see well enough following the surgery to take care of themselves. For a few weeks afterwards, patients typically have to use both antibiotic and anti-inflammatory eye drops to aid the healing process.
