GOTHIC CONTACT LENSES

Suzanne Hughes asked:


Earlier when eye vision needed to be corrected, people preferred glasses. But glasses often can’t be worn while playing sports, as they slip on nose.

Then came contact lenses which are easy to use and manage, and almost undetectable. The contact lens is made up of thin plastic discs that are curvy at the inside so as to fit easily on the eye surface. The lenses are shaped externally so as rectify and better poor eye sight.

This contact lens is also used to bandage the eyes after surgery. There are also cosmetic benefits of lenses like covering eye’s white scarring with them or changing the color of the eye according to the dress for fashion.
Types of Lenses

Disposable lenses: The disposable contact lens is used for a limited time period that might be a day, a week or a month depending on the type of lens. The disposable lens is good for the people who cannot care and clean the contact lens regularly. The disposable contact lens comes in different colors and according to eyes also.

Gas Permeable lens: The gas permeable lens transmits more oxygen to the eyes so as to provide clarity of vision. These lenses are durable and easy to clean so last up to a year. These lenses are made of semi rigid material with no water so the wearer takes some time to adapt to them.

Flexible and extended wear contacts: These are specially designed so that the wearer can use them continuously for several days. One can also take a nap while using the lenses in eyes. This contact lens allows more oxygen to reach the eye cornea.

Annual soft contact lenses: These lenses prevent eyes from drying as its soft material aid oxygen transmission. These lens need good care, cleansing and storage as used for a complete year.

Cosmetic Lens: Four varieties of cosmetic lenses are in the market. They are light-filtering tints, visibility tints, enhancement tints and opaque color tints. The power value of the lens lies in the center so it needs typical cleaning regime daily. But there are also cosmetic lens that are without visual correction.

The contact lenses can now correct all types of visual defects like Astigmatism.

Caring for your contact lens

While wearing contact lens the person feel comfortable with his vision but proper care of lens is also required for preventing any eye infection. You should keep your contact lenses disinfected and clean as contact lenses get so many deposits on them both from the environment and the eye whilst wearing them.

Tears contain lipids, mucous, proteins and calcium that deposit on the lens. The pollutants in the environment like metal and dust particles from cars and factories embed to lens surface.

So to save contact lenses from these deposits, they should be soaked in eye solutions daily for disinfection. If these deposits remain on the surface of the contact lens, it may lead to redness in the eye and recurrent infections. So daily cleaning of contact lens with surfactant cleaner by rubbing in the palm is very important.

Carolina Eye Prosthetics asked:


The days of daily removal and cleaning of an artificial eye are gone. Most ocularists and ophthalmologists now agree that if the ocular prosthesis is not causing irritation to the eye socket, it should be left alone. It may however require occasional lubrication depending on the function of the tear ducts or other natural lubricants of the eye socket. In fact, it is now believed that handling the ocular prosthesis can increase the chance of infection in the eye socket and it should only be handled when necessary. However, the area surrounding the eye socket such as the eye lid and eye lashes should be cleaned daily in order to remove buildup of the eye’s natural secretions. When cleaning this area, it is important to remember to only rub from the outside of the eye towards the nose as not to displace the prosthesis.

Occasionally, the artificial eye can acquire protein build ups or other irritants that may require its removal and cleaning. Before you begin this process, make sure that you thoroughly wash your hands with an antibacterial soap in order to lessen the chances of infecting the socket. To remove the artificial eye, simply pull down the lower lid and look upward, which allows the prosthesis to slide out over the lower lid. Make sure you place the palm of your free hand on your cheek to catch the prosthesis as it slides out. There are also suction cups available to help with the removal of an ocular prosthesis if needed. Once removed, it is important to keep the prosthesis wet with either water or saline solution so that any secretions on the eye do not dry on the surface of the prosthesis. The artificial eye can be gently cleaned with an antibacterial soap and a cotton ball. It is important not to use rubbing alcohol or any other harsh chemical as they can damage the ocular prosthesis.

If needed, you can also clean out the eye socket with a saline solution while the artificial eye is removed. Using a bulb syringe and sterile saline solution, both of which can be found at any drug store, simply flush the eye socket to remove any debris or build up. Once the artificial eye and the eye socket have been cleaned, the ocular prosthesis can be reinserted by holding the prosthesis between the thumb and forefinger and with the other hard, lift the upper eye lid. Then, gently slide the top of the prosthesis under the upper eye lid and hold in place while you pull down the lower eye lid with your other hand so that it slips over the bottom of the prosthesis holding it in place.

Other than occasional at home cleanings, it is important to return to your ocularist once or twice a year in order to have the eye checked, professionally cleaned and polished. This will help ensure a natural look and increase the longevity of the ocular prosthesis. Plus, the ocularist will be able to detect the subtle changes in the prosthesis or socket that may require an adjustment.

Artificial eyes are relatively low maintenance prosthesis and actually benefit from limited care due to decreased risk of damage or infection. For this reason, an ocular prosthesis is easy to care for and maintain and although the concept of removing an eye might seem overwhelming at first, it is rarely required and quality ocular prostheses are designed for simple removal, insertion and maintenance.

Paul Courtney asked:


Like every other part of our bodies our eyes are also subject to wear and tear be it from the ultra violet rays of the sun, pollution and dust in the air, transmittable diseases or stress from looking at a computer screen all day.

Most of us go to our family doctors to undertake a physical exam to see how our overall health is. Other people take their health for granted. Why is it then that many of us disregard our eyesight. To guarantee healthy and normal vision, an annual visit to your eye doctor for your eye care exam is necessary.

Your eyes are like your windows to the world, Our brain receives sensory information daily from our eyes therefore keeping them in an optimum shape will ensure proper signals being received by the brain and consequent action and reactions. If your vision is sub par this will obviously affect your life performance.

Eye care exams should start from a very early age, babies of 2-6 months should have their eyes checked to correct any abnormalities, children entering primary school and again when entering secondary school should undergo eye care exams which will also detect any vision problems and corrective action can be taken to rectify the problem.

As we get older it is of vital importance to have an eye care exam performed yearly because every time you visit your eye doctor they will evaluate any changes in your vision system and they can help you correct any difficulties that you may have with your sight. Early diagnosis of any potential problems will decrease the chance of severe damage to our sight.

Elderly citizens are more susceptible to vision loss, they should be aware that the probability of having vision disorders increases with age. The threat is still there even though you might not be experiencing any problem, therefore you should visit your eye doctor regularly for an eye care exam.

An eye care exam is a painless and informative method for the assessment of your eyes. The eye doctors will test your visual acuity, which is the clarity of your vision. During the eye care exam, the doctor will also check the muscles of the eyes, eye pressure, fluid circulation, retina and general condition of your eyes.. The routine eye examination is not painful or uncomfortable.

Eye Care Exam Doctors

Doctor’s who specialize in the comprehensive care of the eyes and visual system in the prevention of eye disease injury is the ophthalmologist. They are medically trained specialists who can deliver total eye care exams, primary, secondary and tertiary care services and diagnose general diseases of the eyes.

Whereas the health care professional who provides only primary care services is the optometrist. Services included are the comprehensive eye health and vision examinations: treatment and diagnosis of the vision disorders and eye diseases; the detection of general health problems; they prescribe the glasses, contact lenses, vision therapy, low vision rehabilitation and medications.

How Often Should You Have An Eye Care Exam?

If you note that you are having eye difficulty, pain or visual disturbances or any other problem in the eyes, you should immediately see an eye doctor. However, if you are in good health and no known ailments, no vision problems, you can have an eye exam every two to four years provided your age is below forty. For people with diabetes, you need frequent eye examinations to maintain good eye health.

Remember prevention is better than a cure, so make sure you are aware of your vision and if you note any deterioration get on down and have an eye care exam.

Sean Willoughby asked:


 

Before we get to the invention bifocal contact lens, we need to go back a bit further to see the evolution of contact lenses. The idea of the general principal of a contact lens was made my none other than Leonardo Di Vinci in 1508, yes the famous artists who painted Mona Lisa!! Not only was he a painter he was also a scientist, mathematician, engineer, inventor, anatomist, sculptor, architect, botanist, musician and writer. That is a story for another article (a whole book even), so let us get back to the invention of contact lenses.

It wasn’t until the 1800’s that the contact lens made another leap forward. In 1827Sir John Herschel an English astronomer, proposed the idea of making a mould of the wearer’s eyes so contact lenses can be made to conform perfectly to the front of the eye. His idea was slightly ahead of the manufacturing techniques at the time.

Not until 1887 was the idea made into reality by German glassblower F.A. Muller, who made the first glass contact lens. In 1888 Swiss Physician Adolf Fick and Paris Optician Edouard Kalt used Muller’s invention to fit the first glass contact lenses to correct nearsightedness and farsightedness. These lenses were heavy and could only be tolerated for a few hours.

The next significant leap forward came in the 1930s when the first contact lens containing both glass and plastic was introduced by New York Optometrist William Feinbloom. This was the beginning of the modern hard contact lens era. In the late 1940s marks the beginning of polymethyl methacrylate (PMMA) plastic contact lenses manufactured by California optician Kevin Tuohy. The PMMA evolved, getting smaller and thinner and are still available on the market today.

It wasn’t until the 1950s saw the evolution into the soft contact lens by Czech chemist Dr. Otto Wichterle. His experiments using spinning parts from his son’s bicycle led him to produce the first soft contact lens.  The first commercially produced soft contact lenses were made by Bausch & Lomb in 1971. Over 90% of the contact lenses on the market today are soft contact lenses. Due to their ease of handling and disposable convenience, these lens are perfect for those who no longer want to wear glasses.

The first commercially available bifocal contact lenses (daily wear) were introduced in 1982 and the disposable versions in 1999.

As you can see contact lenses were more of an evolution, with each inventor building and advancing from a previous idea. It took over 500 years to get where we are today but I am sure glad we have this amazing invention that many of us can benefit from.

More on Bifocal Contact Lenses

These lenses are for people who have a condition called presbyopia or the inability to focus on things in close range. If you have to hold that menu at arms length to read it, you might have presbyopia. Some physical symptoms might include blurred vision, headaches, eye strain or eye fatigue. If you are tired of wearing bifocal glasses, bifocal contact lenses might be the perfect solution for you.

Bifocal contact lenses are also known as Multifocal or Progressive contact lenses. They all pretty much serve the same purpose, allowing you to see clearly near and far and all distances in between.

Thank you for taking the time to read this article, I hope you enjoyed it.

Happy contact lens hunting.

They correct vision with no distortion, but they are the least comfortable type of contact lens. In other cases, your doctor may recommend using reading glasses in combination with contact lenses that correct for distance vision. For those who are short-sighted a number of contact lens products are now available to restore sharp, clear distance vision. Patients who require correction to improve vision may wish or even need to wear contact lenses to maximize their vision.

Apart from cosmetic lenses, contact lenses allow normal vision for people with a wide range of medical conditions. Infants and young children often have various visual conditions that require a contact lens so that their vision system can develop normally. The main concern with implantable contact lenses is the risk of infection, a potentially serious condition that can lead to loss of vision. Soft contact lenses are available that will change the color of your eyes, even if you don’t require vision correction. Correcting vision is not the only use for contact lenses.

Colored contact lenses are available with no vision correction, and an even more stylised version, called Halloween contact lenses, goes one step further. Nowadays almost all those who need vision correction and want to wear contact lenses can do so. Crazy Eyes novelty contact lenses are available both for those who need vision correction, and those who don%u2019t! High Myopia Patients with a high degree of nearsightedness are known to attain better vision with the use of contact lenses. The Contact Lens specialist will determine what your fee will be based on the type of lenses desired and your particular vision needs.

People who have chronic or recurrent infections or sores on the cornea cannot wear contact lenses. 1982: Bifocal daily wear soft contact lenses became available for commercial distribution. Unless you have been instructed otherwise, remove your contacts at night, even if you wear disposable lenses. Almost anyone with astigmatism can now wear contact lenses. But he isn’t keen on forking out over Rs 1,000 for a pair of contact lens he may wear only once.

Centers for Disease Control and Prevention issued an alert to health-care professionals and patients who wear soft contact lenses of the risk. Following a thorough ophthalmic examination, a patient’s potential for successful contact lens wear is objectively evaluated. editor Neil Fowler said: “Many people who wear long-life contact lenses may be paying over the odds. For some people who haven’t been able to wear contacts and want to, implantable lenses may be an option.

Wear your contact lenses according to the schedule prescribed by your doctor. Toric lenses correct this problem just as well as wearing glasses does, and come as disposabls, extended wear and even colored contact lenses. Safe contact lens wear For most people, contact lens wear is safe and completely trouble free. There are also many practical advantages to contact lens wear for sports and recreational use.

Paul Courtney asked:


Access To Eye Care Is Important For Your Family.

When children are young they are unable to describe how wel they can see things, particularly in the early learning stages and it is virtually impossible for parent to recognize a visual disability in the early stages thus imparing the child’s development.

Ensuring that your family has regular access to eye care, is perhaps one of the most important things for a family’s health. Without proper eye care, children are too often forced to enter school with untreated sight deficiencies, and in turn do not get the education they deserve. Access to eye care is equally important for adults. Even if you need glasses or contacts, allowing your eyes to go unchecked for long can lead to much more serious sight loss.

Choosing An Eye Care Professional

1. To ensure that your family has proper access to eye care, you need to choose an eye care professional that can work with your entire family, regardless of age. Children require a different approach to eye care than adults do, and not all eye care professionals will work with kids. Or, some will work with older children, but not with toddlers, who need access to eye care as well. Before you settle on an eye care professional, ask around to see which ones in your area accept children.

2. In order to ensure that your family has proper access to eye care, choose an eye care professional that offers several different types of payments options. The eye doctor you choose should accept several different insurance companies, as well as offer cash only payment plans. If you have a large family, you may want to look for an eye doctor that offers family discounts as well.

When You Can’t Afford Eye Care

For those who do not have proper access to eye care due to financial difficulties, there are alternative options, as well. Every state has a low income, state funded, health insurance program. Although these programs do not cover much, they do cover annual eye exams in most states. This is true for both adults that qualify, as well as children. Although glasses, contacts, and other specialized optometric procedures are not necessarily covered, the basic yearly visit is. This is one way our government has opted to ensure access to eye care for everyone.

When You Should Start

Although its never too early to start making sure your eyes are in good health, you should provide access to eye care to your children as early as twelve months. It is most important that children have access to eye care as early as possible to help protect against future eye problems. Your entire family’s eye care should be one of your highest priorities. Thanks to the efforts of many eye care professionals to provide access to eye care to everyone, this is now easier than ever!

If your vision is blurry , you are finding it hard to read or make out objects on the horizon or are suffering from head aches then good access to eye care will provide you with the necessary help you need.

S. Geetha asked:


The functional advantages of contact lenses over glasses can be felt in areas like sports, working in humid conditions and also in occupations where glasses can be very inconvenient and may not be compatible when using equipment like special headgears. Contact lenses also offer aesthetic advantages as they do not alter the image of the person wearing it.

When contact lenses are worn correctly on the cornea of the eye, the vision is very similar to the natural vision. The objects are seen in the right size and position without any kind of distortion of the image. When glasses are worn, the distance between the glasses and the eye vary making the objects appear smaller or larger than the actual size, position etc.

Contact lenses are not altered by bodily movements, as in the case of sports or similar kind of activities. They remain stable providing stable and clear vision to the wearer. When glasses are worn, the vision is unstable while moving or running, in turn affecting the performance of the wearer.

Contact lenses provide a better and wider peripheral vision than the glasses. Contact lenses move with the movement of the eyes and the wearer always looks through the clearest part of the lens called the optic zone. When glasses are worn, it blocks the peripheral vision. When the eyes move to the sides, the sight is far from the optic center leading to distorted and blurred vision.

Contact lenses do not steam up due to body heat or perspiration. They also neither fog when exposed to cold weather nor get splattered in the rain. Glasses on the other hand fog up and the wearer cannot see completely during rain pour.

Contact lenses do not leave marks on the nose and are very comfortable to wear. No pressure is felt on the ears, temple, or nose unlike the glasses. Also glasses slide down from the nose during perspiration.

As told before, contact lenses do not alter the appearance of the person. They are boon for children who are often picked up at school for wearing glasses. Contact lenses provide both physical and psychological comfort to the wearer.

Also, after cataract operations, contact lenses provide the necessary protection more than the glasses. Contact lenses offer adequate correction when the visual acuity of the eyes are more than 2.5 diopters, which is not possible with the glasses.
