What actually is a changing schedule? It basically describes how often one must change their pair of contact lenses. These are some important topics to be discussed as the old pair of contact lenses may scratch your eyes if worn past it’s due date or expiry date. There are two significant schedules that the contact lens wearers must follow to maintain good eye health.

One is termed as the wearing schedule and the other is termed as the replacement schedule. The first one that is the wearing schedule mainly refers to the timing for wearing lenses. Like for how many hours, you must abscond your contact lenses and how frequently you must take them away, clean the lenses, and store them?

The second one is a replacement schedule that refers to how often you must dispose old ones and buy new contact lenses. Though many people comprehend how often to eradicate contact lenses but it is also equally imperative for the wellbeing of your eyes to comprehend how often to replace and dispose of your contact lenses. There are countless diverse kinds of lenses to select from and every lens has its own most favorable replacement time duration. Beneath are some of them:

Disposable Lenses: such lenses need to be eradicating off and replaced every day, weekly or twice a week according to company’s directives. Many eye care specialicts promote the use of every day lenses, which are to wear in the morning and then detached and thrown away prior to sleep. This type of an every day rule reduces the hazard of bacteria infecting your contact lenses.

Frequent Replacement Lenses: Such lenses are made to be changed, quarterly, monthly, or biannually on a timetable prescribed by your eye care expert.

Traditional Lenses: These lenses can be reused and must be changed quarterly, twice a year or annually on a schedule prescribed by your eye care expert.

Just for the reason that the cover box says you can use your contact lenses again for up to two weeks it does not imply that your eyes will have the same opinion. Everybody’s eyes endure the application of contact lenses in a different way and a few people’s eyes are more sensitive than others are. Therefore, it is significant to converse a replacement program with your eye care expert and stay with it. If you notice that, your eyes get aggravated easily then you may require a short duration replacement program or a special kind of lens. Even with appropriate clean up and safeguarding material such as lipids and proteins, which are found in tears naturally, upsurge over time and stick on to your contact lenses.

The last three mentioned are normal type of lenses that need proper care throughout their life span!

The contact lenses  have to be kept clean and disinfected at all times. Before you clean the lens, clean the lens case. Clean the case with hot water only and let it dry by itself. Use a contact lens cleaning solution but never hold the bottle at the tip, always hold the bottle toward the end. Wash your hands before you start cleaning the lenses with an antibacterial soap and dry them naturally. Clean just a single lens at a time. Take one lens in a sterilized container, pour the cleaning solution and let it stand for 20 seconds, you will see all the dirt setting aside. Rub the lens and then rinse it in the rinsing solution, dry them and store it in the case. Repeat the same step for the other lens but use fresh cleaning solution and also rinsing solution. Never use water to clean the lens or its case as water does not have the necessary disinfectant to clean the lens. Secondly water has sodium it might contaminate the lens giving you an eye infection.

Disinfect the lens as per the requirement of the lenses. Disinfection is important to kill micro organisms that may potentially cause an eye infection. You can use tablets or solution to disinfect the lens. After you have cleaned the lens, place them in a lens holder and add the disinfecting solution to the top. Tighten and turn the cap. Soak them for minimum 6 hrs or overnight (the instructions on the Disinfectant will give some more directions always read the instructions first and in case of confusion call or go to the pharmacy from where the product was bought). Rinse the lens again before using them. Discard the disinfecting solution from the cup rinse and keep the holder open to dry. Always re-wet the lens before using, this will take away any discomfort if the lens is hurting. Enzyme cleaning is optional and is based on eye care professional’s recommendations only.

When do you have a vision problem? When your cornea - the natural lens inside your eye that has existed since you were born - changes its curvature or experiences a change in its refractive capability, the external light rays do not fall onto the right vision spot (”yellow spot” and its surroundings) inside your eyes. As a result, your vision becomes blurred. The job of your contact lens is to provide the additional refraction so that the focus of the external light entering your eyes is centered on your yellow spot, and you gain back your accuracy of vision. To understand what sort of contact lenses would work the best for you, you need to understand the above-mentioned process in more detail.

Historically speaking, the scientists of the past had observed the refractive properties of glass as well as of water, and had wondered whether such properties could leverage weakened human vision. A series of experiments led to the discovery of eyeglasses. This concept further evolved to place the glass right on the surface of the eye, and eventually this led to the birth of contact lenses. So fundamentally, both eyeglasses and contact lenses work based on the same principle - by providing compensation for the changes in the refractive index of your eyes.

The changes in your eyes can happen in two different ways. Either the shape and/or the refractive index of your eye changes such that the light entering your eyes focuses before the yellow spot, or the light focuses beyond the yellow spot. This leads to nearsightedness or farsightedness. For accurate vision, this light must focus exactly on your yellow spot.

The corrected refractive index provided by the contact lens will let you do exactly that. Once the lens fits your eyes, the light first has to travel through the lens and only then can it reach your eyes. The lens would change the direction of the light such that with your current refractive index of your eyes the focus happens exactly on the yellow spot of your eyes.

Now you understand the reason why your ophthalmologist would examine your eye to figure out exactly how much your eye has deviated from its expected vision levels. Based upon the desired refractive index found and also based upon your habits, lifestyle, and possibly profession, s/he will prescribe the appropriate type of contact lenses for you.

Contact lenses are evolving as technology evolves. So, knowing how the contact lenses fundamentally work and being aware of the different kinds of lenses available, you can make the right choice of your lenses.

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.

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.

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.

Making corrective lenses actually begins at the point of the eye exam, a person is examined by an eye care professional to determine what their prescription is – and then that information is sent off to a lab. Once the numbers are in the technician’s hand, he or she will determine what type of prescription blank is closest to the corrective requirements. The prescription blanks are preformed lenses that are flat on one side and curved on the other and most commonly made of impact resistant plastic. The thickness of the blank selected will be determined by the corrective needs of the individual patient. The prescription lens blank is expertly ground done by the technician until it will provide the corrective properties that are needed by the wearer.

Once the appropriate curvature for the prescription has been reached, the edges of the lens are then ground down to fit the frames that were pre chosen by the patient. It’s at this point in the process that the lenses will be specialized if necessary with things like tinting or UV protection.

Then lenses need to fit securely into the chosen frames so it often necessary to heat them in order to make them pliable before insertion into the frames occurs. Once the lenses are securely installed into the frames it’s time for everything to be cleaned up, packaged and shipped out to your eye care professional for you to pick up.

Though the process doesn’t sound incredibly difficult, it is a very exact science – even a minor error on the part of the technician could render the glasses useless to the patient, so the utmost care and precision must be exacted with every single lens that goes into the grinding machine.

Once you get your eyeglasses, you must exact great care in making sure that they don’t become damaged. Some frames are made to handle abuse, they are flexible and can almost bounce back from instances that would have destroyed and older set of frames – even though the technology with lenses has come a long way they still aren’t capable of holding up well to excessive abuse. If your lenses get scraped up or heavily scratched, it could be back to square one, prescription lenses can’t be ground down to remove marring because that would end up changing the prescription of the lenses and therefore effect the vision of the owner.

If you exercise the caution that you should when wearing your prescription glasses, damaging them shouldn’t be a very big concern but if you are careless in either the handling or cleaning of your prescription lenses you may find that you need a new pair much sooner than would normally be necessary. Prescription glasses can be costly because of the work that goes into producing them properly, most people can’t afford to be replacing a pair of prescription glasses more frequently than is necessary as a result in a change to their prescription. So think about all the care and hard work that goes into crafting your prescription glasses before you do any undue damage to them through improper handling.
