  • Understanding the Potential Causes of Eye Pain

    Almost everyone experiences some sort of eye pain during their lives, so it can be difficult to recognize when sore eyes or eye pain warrants medical attention. In some cases, eye pain disappears over time, but in other cases, eye pain is a symptom of a more serious eye health condition . Here’s a look some of the most common causes of eye pain and their treatment options.

    Causes of Eye Pain - Dr. Mark Hornfeld - NYC


    Commonly known as pinkeye, conjunctivitis is an inflammation in the covering of the white outside wall of the eye. This condition usually develops from contact with an allergen or through a viral or bacterial infection. If someone develops conjunctivitis, the blood vessels in his or her eye inflame, causing the white portion of the eye to appear red. The inflammation is usually accompanied by itchiness and discharge. If a bacterial infection is responsible for pink eye, it can usually be treated within 24 hours with an antibiotic.

    Foreign bodies

    A piece of dirt, plant debris or contact lens fragment can all cause irritation if they become trapped in the eye. Usually, these foreign bodies cause some irritation until tears or water rinse them away. However, foreign bodies that aren’t removed from the eye can scratch the cornea and lead to longer-lasting eye pain and vision problems .


    Glaucoma usually shows no early symptoms or signs, but it is a very serious eye condition that can damage the optic nerve. Usually a hereditary eye condition, glaucoma is often associated with building pressure inside of the eye. This mounting pressure can damage the eye’s optic nerve, which is responsible for sending images to the brain. As a result, failure to prevent further damage to the optic nerve can lead to permanent vision loss.

  • A Look at Vision Health After 40

    Many adults begin to notice difficulty seeing objects at close distances beginning in their early to mid-forties, especially when reading or working on the computer. The reason for this change is a condition known as presbyopia, the normal aging process of the eye over time. Even though everyone experiences different symptoms as their eyes begin to age, there are some common, noticeable changes that someone may begin to develop.

    Need for better lighting

    Once someone’s eyes begin to age, he or she may find it difficult to see objects as clearly as he or she did in years past. Reading books, paperwork, or working at the computer are all tasks that may require brighter lights in the work area or next to a reading chair.

    Difficulty reading

    Over time, the eye lens loses its flexibility, making it more difficult for someone to see printed materials as clearly as before. At the same time, people over the age of 40 may find it more difficult for their eyes to focus near objects in the same way they could when they were younger.

    Problems with glare

    Glare from headlights at night or the sun reflecting off the windshields or pavement may be more prevalent as the eyes begin to age. As the eye lens changes, light entering the eye may scatter instead of focusing precisely on the retina, which leads to additional glare.

    Reduced tear production

    The tear glands also begin to produce fewer tears with age, especially in women who have experienced menopause. Decreased tear production can result in dry and irritated eyes. People who experience limited tear production should consult their ophthalmologist about using eye drops, as tear production plays an essential role in keeping the eyes healthy and maintaining clear vision.

    Even though vision problems are a common part of the aging process, certain symptoms may signal a more serious eye condition.

  • Tips for Preventing Dry Eyes

    Preventing Dry Eyes - Dr. Mark Hornfeld - New York City

    Your tears are made of a mixture of water, fatty oils, and mucus. Together, this solution helps keep the surface of your eyes smooth while simultaneously protecting against infection. If your tear ducts aren’t able to provide adequate moisture, you may suffer from a condition called dry eyes.

    There are a variety of factors that can cause you to develop dry eyes, including an imbalance of the composition making your tears. Other causes may include environmental factors, eyelid problems, or medications. Your tear production typically decreases with age, so you are a greater risk of developing dry eyes if you are over the age of 50. Luckily, you can usually help prevent dry eyes by paying close attention to the situations that cause your symptoms. For example, you may be able to help improve dry eyes by avoiding air from hair dryers, heaters, and fans. In the winter, you can help add moisture to dry indoor air by using a humidifier.
