Contact Lenses Eyeglasses

Our eyesight is a precious gift, so no matter what your age, taking care of your vision is essential to good health. The brain is primarily responsible for managing the vision process. The brain processes the light information our eyes collect to create the images that allows us to see. In order to make sure our brain’s vision process maintains optimal performance, we need to nourish our eyes with healthy foods rich in vitamins and minerals.

All of the vitamins that are good for the eyes are Vitamins A, B, C, D, and E. Some of the most important vitamins needed to maintain optimal eye health include:

Vitamin C:  This vitamin has been associated with the prevention of cataracts, delaying macular degeneration, and reducing eye pressure in glaucoma patients. Our bodies are unable to store Vitamin C; therefore it needs to be replenished regularly.

Vitamin A: This vitamin is essential for eye and vision health. In our bodies, vitamin A is essential for the retina to help it function properly. One of the causes of night blindness is Vitamin A deficiency.

Lutein:  Lutein reduces the risk of cataracts and macular degeneration. Low Lutein levels have been shown to be a risk factor in age-related macular degeneration. Lutein may also help to prevent or slow the rate of atherosclerosis.

Vitamin E: This vitamin helps protect against cataracts and age-related macular degeneration.

Copper Gluconate: This is an absorbable form of the mineral copper. It is one of the most important blood antioxidants which help the blood carry oxygen and other nutrients to the rest of the body. The eyes are one area that requires oxygen. If there is a decrease in the transport of oxygen to the eyes, eventually vision loss can take place. Copper can be found in such foods as seafood, beans, nuts, organ meats, and whole grains.

When you choose foods for promoting and maintaining good eye health, you need to choose leafy and green fruits and vegetables. The brighter and deeper colored produce are full of the highest levels of vitamins and minerals.  They are packed full of antioxidants, which are essential for the eye lens, as well as for retinal, conjunctival, and corneal health. These vitamin and mineral rich foods nourish your eyes.

Among the foods that help you strengthen your eyes and see better are carrots, celery, parsley, spinach, bean sprouts, turnip greens, beetroots, cucumber, raw egg yolk and liver. Also recommended are tomatoes, beets and red peppers, apricots, raisins, sunflower seeds, pecan nuts, wheat germ, sweet potatoes, mangoes, cantaloupes, peaches, soy beans and lecithin. Blending the red foods with the dark green foods will give you all of the essential vitamins and nutrients required for good eye health. Dark green foods can include broccoli, kale, spinach, collard greens, and water cress. Avocado, asparagus, and yams are a great source of Vitamin E. Foods rich in Vitamin A includes sweet potatoes, carrots, mangoes, spinach, and cantaloupe.

It may seem difficult to change one’s diet. For the health of your eyes, you should adopt a health diet rich in vitamins and minerals. By including eye nourishing foods in your diet, you will not only find your self seeing better, but feeling over all good health.

Low Vision, also referred to as poor vision, is when a person loses their sight which is not completely restored using such aids as surgery and prescription eyeglasses. Such sight loss can include poor night vision, blind spots, and a glare preventing one from seeing clearly. Total blindness is not considered low vision because there is still some sight with low vision. Low vision is normally associated with people who are “legally blind” and require vision aids.

The American Optometric Association classifies low vision in two categories:

Partially Sighted: Visual acuity is between 20/70 and 20/200 with conventional prescription lenses.

Legally Blind: Visual acuity no better than 20/200 with conventional correction and/or a restricted field of vision less than 20 degrees wide.

The World Health Organization classifies visual impairment as:

-    20/30 to 20/60:  Mild vision loss, or near-normal vision
-    20/70 to 20/160: Moderate visual impairment, or moderate low vision
-    20/200 to 20/400: Severe visual impairment, or severe low vision
-    20/500 to 20/1,000: Profound visual impairment, or profound low vision
-    less than 20/1,000:  Near-total visual impairment, or near total blindness

Low vision can result from a number of conditions that can include inherited diseases, birth defects, macular degeneration, glaucoma, cataracts, and physical injuries. It can also result from such circumstances as diabetes, cancer of the eye, albinism, or a brain injury. Eye care specialists can diagnose low vision by using lighting, magnifiers, and visual testing charts. Low vision is often seen in adults over 45, especially the elderly.

The most common types of low vision include:

-    Central Vision Loss: A blind spot in the center of a person’s vision.
-    Peripheral Vision Loss:  Cannot see on either side, above or below eye level.
-    Night Blindness: Problems seeing in poorly lit areas.
-    Blurred Vision: Objects both near and far are blurry. For instance, refractive error is an eye disease where the shape of the eye does not bend light properly, resulting in a blurry image. Common refractive conditions include myopia (short sight) hypermetropia, (long sight) presbyopia, (aging of the lens) and astigmatism (irregular curvature of the lens.)
-    Hazy Vision:  Vision appears to be covered with a film or glare.

Sign that may suggest low vision include:

-    Not recognizing faces
-    Performing activities where you find yourself looking closely such as when reading, watching television, or sewing.
-    Picking out the wrong clothing colors.
-    Turning on bright lights to see well.
-    Unable to read street signs

Low vision can often be treated using such aids as hand magnifiers, lenses that filter light, reading prisms, magnifying glasses, telescopic glasses, and closed-circuit television.
Non medical aids that can help a person with low vision include talking watches and clocks, text reading software, large print books and magazines, clocks, phones, and watches that have larger numbers, etc.

Due to technological developments in the field of low vision rehabilitation, today most people suffering from low vision can be helped to improve the quality of their lives. Visual aids improve both sight and the quality of life for many people. If you are having problems with your sight, see an eye doctor for testing.

Whether you are a new contact lens wearer or you have been using them for years to correct your vision, you may be wondering how can you tell if a contact lens is inside out. If you suspect you may be wearing your contact lenses incorrectly or they just feel uncomfortable, here are some ways you can determine this to avoid the problem in the future.

Look at the Lens

Before placing the lens in your eye, hold it on the tip of your index finger and look at it carefully from the side. Is it shaped like the letter “U” or it is flared on the sides, like a soup bowl? The correct shape of a soft contact lens should be like the letter “U”. If it’s shaped like a soup bowl, then it’s inside out. Some people also recommend the “taco test” whereby you gently squeeze the lens so that the edges touch. If they touch completely, then the lens is right side out. If the edges flare out and don’t touch fully, then it’s inside out. Simply flip the lens around and it will be positioned correctly for wearing.

Another way to determine if your contact lens is right side out is to look at it from the top. This is especially important if you are wearing the colored enhanced type. The edge of a tinted lens will be look very blue. If it looks greenish, then it is inverted and you should carefully flip the lens around in order to wear it properly.

Find the Engraving

Some contact lenses have factory engraving on them, done by special lasers. This can include the manufacturer information, model number, brand name or grade of materials used. While this is not detected by the human eye when wearing, it can be of help when trying to determine if you are wearing your contact lenses correctly. Some brands have a “1-2-3″ engraved on them, so you would make sure this is the side facing downwards on your finger as you place the contact into your eye. If you can read this label, then the lens is inside out. You can remove it safely without damaging your eyes and flip it around for replacement.

Ask the Professional

Of course, please check with your eye doctor if you experience any discomfort with your contact lenses. They can often help you more with this perplexing problem or demonstrate to you further what to do. Common sense should tell you if you are wearing your contact lens incorrectly. If they feel uncomfortable or you feel slight pressure on your eyes, it’s probably because you have placed the lenses incorrectly on your eyes. You may want to practice a little when first getting a new set of contact lenses to see what works best for you and to get used to the feel of them. Once you do, you should enjoy months of enjoyable experience with your new lenses.
