People who consistently follow a healthy diet that includes colorful fruits, vegetables, and whole grains may show a decreased risk of cataracts. Antioxidant vitamins and phytochemicals found in fruits and vegetables that may reduce the risk of cataracts include vitamins A, C and E, lutein, and zeaxanthin. Consumption of fish, which is high in omega-3 fatty acids, also has been linked to potentially reduced risk of cataracts or their progression. Some recent studies have shown that the antioxidant vitamins C and E may decrease the development or progression of cataracts. The Nutrition and Vision Project found that higher intakes of vitamin C reduced the risk for cortical and nuclear cataracts. Results also showed that people who used vitamin C and E supplements for more than 10 years decreased the progression of nuclear cataracts.

What Is Retinoscopy?And How Does It Help?

Posted on Updated on

Retinoscopy is a technique to obtain an objective measurement of the refractive error of a patient’s eyes. The examiner uses a retinoscope to shine light into the patient’s eye and observes the reflection of the patient’s retina. while moving the streak or spot of light across the pupil the examiner observes the relative movement of the reflex or manually places lenses over the eye to “neutralize” the reflex.

Static retinoscopy is a type of retinoscopy used in determining a patient’s refractive error. It relies on Foucault knife-edge test, which states that the examiner should simulate optical infinity to get the proper refractive power. Hence, a power corresponding to the working distance is subtracted from the gross retinoscopy value to give the patient’s refractive condition, the working distance lens being one which has a focal length of the examiner’s distance from the patient.

Myopes(short-sighted) display an “against” reflex, which means that the direction of movement of light observed from the retina is a completely different direction to that in which the light beam is swept. Hyperopes, on the other hand, display a “with” movement, which means that the direction of movement of light observed from the retina is that the same as that in which the light beam is swept.

How Does it Help:

Retinoscopy is particularly useful in prescribing corrective lenses for patients who are unable to undergo a subjective refraction that requires a judgment and response from the patient.In most tests, however, it is used as a basis for further refinement by subjective refraction. it is also used to evaluate the accommodative ability of the eye and detect latent hyperopia.

Whether you’re near or farsighted, or you have astigmatism, examining the way light reflects off your retina is a way your optometrist is able to determine if you need eyeglasses.In short, what we are doing during a retinoscopy exam is checking how well your eye focuses. we shine light into your eye because we are looking for what we call the red reflex.

The retinoscope sends light into your eye, and a red or orange light reflects through your pupil and off your retina. The retinoscope measures your focal length, or in layman’s terms, it will determine the angle of refraction of light off your retina that tells us how well your eye focuses. And if it’s apparent that you can’t focus well, we hold several lenses with varying prescriptions in front of the eye to see which one corrects the error.

What is glaucoma and the way to detect it early??

Posted on Updated on

glaucoma image1

Glaucoma is a group of diseases that harm the eye’s optic nerve, which carries visual signals from the eye to the brain. glaucoma is that the second commonest cause of blindness in the world. This disease happens because of exaggerated pressure in the eye. The pressure causes injury to the optic nerve. this can cause loss of vision, and may also be painful.

Sometimes, it’s hard for an individual to understand that they have glaucoma. The vision can be lost very slowly. There are 2 types of glaucoma, the type that happens very fast, and the kind that happens slowly, over a long time. the most common type is open-angle glaucoma, chronic glaucoma, and glaucoma with less common types including closed-angle glaucoma and normal-tension glaucoma.

open-angle glaucoma develops slowly over time and there is no pain. side vision may begin to decrease followed by central vision leading to blindness if not treated. Closed-angle glaucoma can present gradually or suddenly. The sudden presentation may involve severe eye pain, blurred vision, mid-dilated pupil, redness of the eye, and nausea. Vision loss from glaucoma, once it has occurred, is permanent.Early detection, through regular and complete eye exams, is the key to protecting your vision from damage caused by glaucoma.

A complete eye exam includes 5 common tests to detect glaucoma

It is necessary to have your eyes examined frequently. Your eyes should be tested:

  • before age 40, every two to four years
  • from age 40 to age 54, every one to three years
  • from age 55 to 64, every one to two years
  • after age 65, every six to twelve months
  • Anyone with high-risk factors should be tested every year or two after age 35.

The good news is that glaucoma can be detected in its early stages through a comprehensive dilated eye exam.” With early detection, glaucoma is controlled through medications or surgery. Early treatment will protect the eyes against serious vision loss because glaucoma can begin to develop without noticeable symptoms, the best way to protect your sight from glaucoma is to have regular comprehensive eye examinations to assess your eye pressure, optic nerve health, thinning of the cornea, and other signs of potential problems.

The comprehensive eye examination includes:

A Health and Medication History

  • Your overall health and that of your immediate family
  • The medications you’re taking (prescription and over-the-counter)
  • Questions about high blood pressure (hypertension), diabetes, smoking, and sun exposure

A Vision History

  • How well you can see at present, as well as any recent changes in your vision
  • Eye diseases that you simply or your family members have had, including macular degeneration and glaucoma
  • Previous eye treatments, surgeries, or injuries
  • The date of your last eye examination

Visual Acuity Testing

  • Distance and near vision acuity tests to determine the sharpness or clarity of your reading and distance vision
  • Testing your vision with totally different lenses sometimes contained in a machine called a phoropter, pictured at right to determine if your vision can be improved or corrected with regular glasses or contact lenses. this can indirectly help your doctor determine the size of your eye to determine whether you are in danger for particular types of glaucoma.

Basic visual field Testing

  • This test is completed to determine how much what proportion what quantity side (or peripheral) vision you have and how much surrounding area you can see.
  • The most common type of visual field test in a regular eye exam is called a confrontation field test. This test measures only the outer edge of the visual field and will not reveal changes in early glaucoma.

An Eye Health evaluation

  • An examination of the anterior segment of your eye (the front third of the eyeball), including the cornea, pupil, iris, lens, and aqueous drainage structures, using a special microscope known as a slit lamp.
  • A dilated eye (or fundus) examination that can that may be achieved with the use of special lenses will allow your doctor to see inside your eye and examine the retina and optic nerve. Your doctor might choose to prefer to like better to value more highly to favor to opt to use eye drops to see the retina and optic nerve more clearly.

Eye exercises to reduce eye strain

Posted on Updated on


oct24th-contacare-blog copy

Eyes exercise is a set of massage methods that aims at promoting students’ awareness of eye-protection, improving blood circulation and relaxing muscles in ocular region, relieving asthenopia and preventing myopia. Eye strain also known as asthenopia is an eye condition that manifests itself through nonspecific symptoms such as fatigue, pain in or around the eyes, blurred vision, headache, and occasional double vision. Symptoms often occur after reading, computer work, or other close activities that involve tedious visual tasks.

Here are a few simple exercises to help rejuvenate and reduce the strain on your eyes:

Repeated blinking: Since a lack of blinking is one of the contributing factors to computer-induced eyestrain, as it dries your eyes, it’s very important to blink. Blinking every 3or4 seconds helps in reducing eye strain.  When we watch tv or work on the computer we tend to blink less, allow your eyes to rest by blinking every few seconds.

Eye Rolling: Take a minute and make sure you roll your eyes while you’re working. Try rolling your eyes, tracing as big a circle as possible. Repeat about 4 times, then close your eyes, focus on your breathing and relax.

Palming: Start this exercise in a comfortable position. Rub your hands together for about 10 to 15 minutes till they’re slightly warm, now place them upon your eyes. Don’t touch the eyeballs directly, instead just keep your hands lightly over your eyes.

Focus on a distant object: It’s important to take your eyes off the computer screen and look away at something else for several seconds or a minute. Choose an object that is about 6 to 10 meters away from you and focuses solely on it for a few seconds without moving your head much. This gives some respite to the ciliary muscles that tend to be under a lot of stress.

Contact lens is a type of soft lens that you put directly into your eye in order to help you see better. They are a different option instead of glasses. They have to be prescribed by your eye doctor. Some contact lenses can be used many times, while other types are used only once and then thrown away (disposable).

The following guidelines for care of contact lenses:

  • Wash your hands so that you don’t transfer dirt and germs to your eye. Try to avoid moisturizing soaps, as they are not good for contact lenses. Dry your hands with a lint-free towel.
  • Wear and replace contact lenses according to the schedule prescribed by your eye care professional.
  • Minimize contact with water, including removing lenses before going swimming or in a hot tub.
  • Follow the specific contact lens cleaning and storage guidelines from your eye care skilled and also the solution manufacturer.
  • Keep the contact lens case clean and replace it regularly, at least every three months. Lens cases can be a source of contamination and infection. do not use cracked or damaged lens cases
  • Contact lenses shouldn’t be rinsed with or stored in water (tap or sterile water).
  • During cleaning, rub your contact lenses along with your fingers, then rinse the lenses with solution before soaking them. This “rub and rinse” method is considered by some specialists to be a superior method of cleaning, even if the solution you are using is a “no-rub” variety.
  • Rinse the contact lens case with fresh solution, not water. Then leave the empty case open to air dry.
  • Do not use saline solution and rewetting drops to disinfect lenses. Neither is an effective or approved disinfectant.

Lasik Surgery:

LASIK surgery is the most common laser eye procedure to correct vision problems and it can fix all problems which are myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. During LASIK, an eye surgeon cuts across the cornea of the eye and raises a flap of tissue and carries out reshaping to good vision. In most cases, LASIK surgery is pain-free and completed within 15 minutes. The results improved vision without eyeglasses or contact lenses can usually be seen in as little as 24 hours. LASIK, might not be appropriate for individuals with strong lens prescriptions, like a high degree of short-sightedness.

No process is without risks, and complications can happen in fewer than 1 in 20 laser eye operations. 1 in 3 individuals patients will still ought to glasses some of the time when laser eye surgery, such as for night driving.

Benefits of Lasik Surgery:

  • LASIK laser eye surgery is associated with very little pain.
  • A high success rate.
  • Faster Results and Recovery
  • In most cases, no bandages or stitches are required, and patients can resume their normal schedule within 24 hours.
  • You may be able to eliminate the need for eyeglasses or contacts completely or reduce your vision correction prescription dramatically.
  • It works and is proven to correct vision in most cases.
