When looking at an object, light is received through the pupil. It is then focused onto the the back of the eye, where there is a collection of light sensitive cells called the retina. A cataract occurs when the eye’s normally clear lens becomes fogged up, making it hard or even impossible for light to travel properly through the lens and be clearly focused on the retina.
Cataracts are often considered a common part of aging. The lens, which is made of mostly water and protein, grows excess layers on its surface as the years go by. When these layers harden, protein in the lens may form clumps and become cloudy, forming a cataract. Although cataracts are usually considered an eye condition of old age, previous eye disease or eye surgery, chronic disease, diabetes, and eye injuries can bring on cataracts much earlier.
“Increased difficulty seeing at night or in dim lighting is another easily overlooked symptom. You should consult your eye care professional for an appointment if you have any of these symptoms and, if diagnosed, be sure to have regular check-ups thereafter.”, Dr. Wedeking, Hebron eye doctor.
Cataract surgery involves the removal of the cloudy natural lens and replacement of the natural lens with an artificial lens made of plastic, silicone or acrylic. The surgery is extremely low risk and is normally done as an outpatient procedure without overnight stay.
Treatment of a cataract varies. In cases in which clouding is minimal, vision is hardly affected and a slight change in eyeglasses prescription may be enough. Alternatively, if all or a large part of the lens is clouded, surgery is required to restore sight.
Proper pre- and post-op care are very important. Proper co-management means your optometrist and eye surgeon are on the same page when it comes to your treatment before, during and and after surgery.” A thorough exam should be conducted by your primary eye doctor to diagnose and decide on treatment of your cataract. After this your doctor should be able to advise about the surgery and refer you to a surgeon, who will answer any questions you have about the surgery. Afterwards, follow ups should take place with both your surgeon and your optometrist to assess your recovery.

Sometimes a person is unable to produce enough tears or their tears do not possess the right qualities to keep eyes healthy and comfortable. This can cause a consistent lack of sufficient lubrication and moisture on the surface of the eye, known as dry eyes.
Normally, the eye constantly lubricates itself with tears by producing them at a slow and steady rate, keeping itself moist and comfortable. Usually these tears consist of three layers, an oily, a watery, and a mucus layer. Each layer has a specific role in lubricating your eyes. The oily layer is outermost. It’s main purpose is to slow evaporation of the tear. The watery layer is in the middle. This makes up the majority of what a person normally thinks of as tears. This layer cleans the eye and helps to wash away small foreign objects and particles. The inner layer consists of mucus. This mucus allows the watery layer to stick to the eye and spread evenly over the eye in order to keep it lubricated. In a person with dry eyes, either hormonal changes, side effects from medication or some other factor causes the eye to either not produce enough tears, or leave out parts of the tear that make proper lubrication possible.

Dr. Alexandra Sadanowicz, of Colchester Eye Care and Hebron Eye Care in Hebron, Connecticut explains, “Symptoms of dry eyes include stinging or burning in the eyes, scratchiness, and excessive irritation from smoke or wind. Although it may sound counter-intuitive, the eyes’ response to the consistent irritation caused by dry eyes may also cause a person to experience excessive tearing. In this case, the eye is attempting to flush and lubricate itself by producing more tears, but is unable to do so successfully due to the rate of evaporation or inability to spread the tears properly.”

Although dry eyes are not always curable, your optometrist may prescribe artificial tears to help with some of the symptoms. Artificial tears are lubricating eye drops that may help with dry, scratchy feeling eyes. Different artificial tears work in different ways. Some help replenish parts of the tear that your eyes are not producing on its own, others help to produce more tears overall. Your eye doctor will assist you to choose which will help you most. Dr NAME cautions, however, “These artificial tears should not be confused with eye drops that are advertised to ‘get the red out.’ These eye drops may indeed reduce the appearance of redness in your eyes, but this is accomplished by making the blood vessels in your eyes smaller rather than actually lubricating your eyes. As such, these drops can sometimes actually make your symptoms worse. One should also be aware that if you wear contacts, some eye drops require you to take them out before using the drops and wait 15 minutes or more before reinserting your contact lenses.”
Some cases of dry eyes are seasonal, such as those which occur as a result of cold, dry winter air. In this case, your eye doctor may recommend wearing sunglasses or goggles when outdoors to reduce your eyes’ exposure to the sun, wind and dust. For indoors, your optometrist may recommend an air cleaner and humidifier to take dust out of the air and add moisture to air which is too dry.
Studies have also shown that nutrition may have a part in helping to relieve some symptoms of dry eyes. Your eye doctor may recommend nutritional supplements such as omega-3. Good sources of omega-3 fatty acids are cold-water fish, cod, herring and salmon, as well as flaxseed oil. Mild dehydration can make symptoms worse too, so be sure to drink plenty of water, 100 percent fruit and vegetable juices and milk.
