You have three different layers of tears in your eyes—a bottom layer produced by thousands of individual cells, a watery middle layer, and an oily layer on the outside of the eye which keeps tears from evaporating.
This video examines the causes of dry eyes syndrome. In most cases, dry eyes syndrome occurs when the cells that produce the bottom layer of tears begin to deteriorate and no longer replicate or reproduce. Other causes of this condition include the use of certain medications, evaporation during windy conditions, and blocked sebaceous glands. Watch this video for information about what you can do about dry eyes syndrome.

Macular degeneration is an eye disease characterized by deterioration of the macula, which is the part of the retina responsible for central vision. Next to glaucoma, age-related macular degeneration (AMD) is the leading cause of blindness and affects millions of individuals in the United States. Continue reading to get the facts regarding this detrimental eye disease.
The two types of AMD are dry AMD and wet AMD . Dry AMD accounts for approximately 90 percent of all cases and occurs when tiny proteins and “drusen” fat deposits build up between the photoreceptors inside the retina. Wet AMD develops as a result of abnormal blood vessel growth beneath the macula which causes leakage of blood and fluid, ultimately causing damage to the retina’s photoreceptor cells.
There are a number of factors that may increase your risk of developing macular degeneration. These include having a family history of the disease, being of Caucasian descent, and using tobacco products. Individuals with high blood pressure and high cholesterol may also be at an increased risk for macular degeneration.
The symptoms of macular degeneration will increase in severity as the disease progresses. Common signs of AMD include blurred central vision, distortion of straight lines, blind spots, and headaches.
The treatment options available for macular degeneration include anti-VEGF injections to control endothelial growth of abnormal blood vessels, photodynamic therapy, and laser surgery. Your ophthalmologist can help you determine which treatment method is right for you based on the type and severity of your macular degeneration and your overall health status.

LASIK surgery is an innovative vision correction procedure which uses laser energy to reshape the corneal lens and treat a number of refractive errors, including myopia, hyperopia, and astigmatism. A good way to determine if you can benefit from LASIK surgery is to consult with your New York City ophthalmologist. Continue reading to learn what you can expect from your initial LASIK consultation .
Patient Medical History Questionnaire
Your LASIK surgeon will have you complete a patient medical history questionnaire at the beginning of your appointment. This may include questions regarding your family history of disease, personal history of eye conditions, previous surgeries, current medications, and lifestyle factors.
Once you have finished your questionnaire, you will meet with your ophthalmologist. After discussing the reasons for your visit and any symptoms you have, your eye doctor will perform a number of tests to assess the health of your eyes and determine your candidacy for surgery. During this exam, your eye doctor may evaluate the shape and thickness of your cornea , assess pupil size, determine the severity of refractive errors, and use a corneal topographer to measure the curvature of your cornea.
Discussion of Procedural Options
The last part of your LASIK consultation will usually include an in-depth discussion regarding the results of your eye exam and your potential treatment options. This is your time to ask questions, so be sure to talk to your doctor about the different types of LASIK available, how you should prepare for surgery, what you can expect during the procedure, and what changes you will need to make during the recovery period.

Your eyes are your windows to the world, allowing you to see shapes and colors and identify objects during everyday activities. However, the function and integrity of your eyes can change over time, leading to the need for prescription eyewear or LASIK surgery. While only your ophthalmologist can determine if vision correction is necessary for you, you can find out more about your visual acuity by learning how your eyes work. Check out this guide to eye anatomy to learn more.
Parts of the Eye
Your eye is approximately one inch in diameter and features several different components. The iris is the pigmented or colored part of your eye around your pupil, which is the black circular opening that allows light into your eye. Your cornea is the clear lens that covers your iris and pupil and is responsible for reflecting light onto your retina. The white portion of your eye is known as the sclera, while the clear layer of tissue that covers the front of your eye is the conjunctiva.
Functions of the Eye
When light enters your pupil, it is reflected off of your cornea and onto your retina, which is an area on the back of your eye that contains light-sensing cells. These cells convert light into electrical impulses, which are then sent to the brain via the optic nerve, where they are translated into visual representations.
Common Conditions of the Eye
There are a number of problems that may interfere with your ability to see clearly. These include myopia (nearsightedness), hyperopia (farsightedness), and astigmatism, all of which involve having a cornea with an abnormal shape. Other eye conditions that may impact your vision include presbyopia, cataracts, glaucoma, diabetic retinopathy, and macular degeneration.

There are a number of factors which can impact the health and integrity of your eyes, including genetic makeup, increasing age, overall health status, and traumatic injury. You may be surprised to discover that the foods you eat can also have an impact on your eye health . Read through this blog to find out more about the foods that support eye health and vision.
Carrots are great sources of beta carotene—an antioxidant which can help reduce the risk of cataract development and macular degeneration. Consider cutting up raw carrots for a healthy snack and dipping them in salsa, hummus, or just eating them plain. You can also add carrots to your salads and soups.
Eating broccoli is beneficial for your eye health because it contains a number of antioxidants, vitamins, and nutrients which can help ward off cataracts. In fact, a single serving of broccoli contains vitamins C, K, A, B6, B2, B5, B1, B3, and E, as well as folate, fiber, potassium, phosphorous, magnesium, omega-3 fatty acids, iron, calcium, and zinc.
Another green vegetable you may want to start adding to your diet is spinach, which contains four eye-protecting nutrients: beta carotene, lutein, zeaxanthin, and vitamin C. These nutrients act as a barrier against diseases like macular degeneration by absorbing between 40 and 90 percent of blue light intensity.
According to the American Academy of Ophthalmology , adding cold-water fish like sardines, tuna, halibut, and wild salmon to your diet may help reduce the risk of eye diseases. This is because these fish contain high levels of omega-3 fatty acids.
Oranges, grapefruits, lemons, and tangerines are high in vitamin C. As a result, they can help reduce the risk of cataract development and age-related macular degeneration.
While eating a balanced diet is important for your eye health, it is also essential to undergo routine eye exams. Let Dr. Mark Hornfeld of NYC’s Vista Laser Vision protect your visual acuity and overall eye health. Learn more by contacting us online or by calling (212) 580-8881 today!
