While the video specifically covers Acuvue brand lenses, we think it’s a pretty accurate representation of proper use techniques for virtually all contact lens brands. Contact lenses are a nice way to maintain your corrected vision without the added hassle of bulky glasses. Once you know how to use them correctly, you’ll find you’re more comfortable and the lenses themselves become almost second nature to you.

Stuck for creative ideas? Here are some of the more popular styles that are being requested: spirals, cat eyes, wolf eyes, eagle eyes, bloodshot eyes, flames, all-white, all-black. Make sure whichever ones you choose electrify Halloween costumes the best. There is literally no end to the combinations you can choose from.

Popular styles of Halloween Contact Lenses

An important thing you need to consider when choosing these contacts is whether or not you want the contacts to cover the whites of your eyes, or only the pupils. There are many to choose from in either style, so this can undoubtedly make it easy or difficult to choose, depending on how easily you can make up your mind.

What is the specific look that you are targeting? Knowing this will help you in your selection a great deal. For example, are you simply going for a generic character(a clown, a witch), or are you aiming for a specific character(the Joker, the witch from the Wizard of Oz)? In choosing contact lenses that cover the whites of your eyes, you will notice that a total transformation is possible, and you will become closer to achieving your conversion into the character want to be. However, if you want to take the generic route, a simple pupil effect may do the trick(or treat), operating in much the same way as a temporary tattoo.

Some other all-time favorite selections include the Manson eyes, Vampire Red eyes, White Cat eyes, Ice Blue eyes, and eyes which recreate characters from your favorite horror and/or science fiction movies. The beauty of decorative contact lenses is that they can be used for a wide array of characters, from past to present, and their appeal never seems to go away.

Because by law(the FDA) you need to consult with a vision specialist before getting any type of contact lenses, it is important for you to be cleared by an ophthalmologist when selecting costume contact lenses. If you choose not to go this route, not only are you breaking the law, but you could unknowingly cause irreversible damage to your eyes, including blindness. Play it safe – make sure you get a precautionary eye exam before you consider using cosmetic contact lenses. You will also need this consultation to find the proper size, instructions, and prescription – it does not matter if you have 20/20 vision or not. Even though you may find some stores online which will sell you decorative contact lenses without a prescription, do not wrongly assume that you can use them – it would be illegal in the eyes of the law.

Naturally, these contact lenses are not for everyday use – use them only occasionally. Be sure not to go to sleep with them on, and do not go swimming or take a bath or shower with them. If you feel that decorative lenses may impair your vision when you need to see most(i.e. driving), then take them out until you are able to use them.

You should not wear your costume lenses for longer than you need to, as this could cause unnecessary eye strain and may cause eye infections. Make sure that they are sterilized in the solution before you put them in each time you use them. If you experience any type of swelling, redness, pain, or runny eyes, you should visit your doctor immediately to see if there may be a more serious situation. It’s better to be safe than sorry; after all, that is what Halloween is all about, isn’t it? The horror and danger is only play – don’t create a horror story for yourself this Halloween by damaging your eyes.

Have a safe and happy Halloween!

The results of the study showed that the general self-worth of shortsighted children between the ages of 8 and 11 was not affected by wearing either contact lenses or glasses. However the study did show that there was a slight improvement in contact lens wearers when it came to physical appearance, athletic competence, and social acceptance.

See our article on Contact Lenses and Children for more information. You should only consider contact lenses for children if the following holds true:

• The child needs to wear glasses all the time
• The child wants to wear contact lenses or is reluctant to use glasses.
• Parents are happy for the child to have contact lenses. 
• The child must be old enough to understand contact lens care including the maintenance, handling, and hygienic aspects, see our Caring for soft contact lenses for details.

Daily contact lenses can be a good starting contact lens for children as they require no complicated cleaning procedures because a new contact lens is inserted every morning. There are a number of popular daily contact lenses:

• Focus Dailies (90 Pack) – Not only one of the best daily contact lens but also the cheapest as well.
• 1-DAY ACUVUE
• 1-DAY ACUVUE MOIST

Many people are not able to have LASIK eye surgery, contact lens implants may be the alternative they have been looking for. Unlike LASIK surgery where the shape of the cornea is permanently changed contact lens implants does not affect the shape of the cornea and has the added bonus of being able to be corrected for in the future in case your eye prescription changes. The procedure involves minor surgery in which the patient is awake taking about ten minutes each eye. The eye doctor performing the surgery makes a self healing cut in front of the patients lens and inserts the contact lens.

“We have a lens that we can remove if we want to do something, (if) a new technology comes out and we want to do something down the line,” Dr. Whitman said. “And we haven’t interfered with the structure of the eye at all.”

“It left me more options than LASIK did,” Hardeman said. “For later on in life, if my eyesight had to change a little bit, I (am) still able to fix that.”

This technology has been used for many years in other countries and has been approved for use in the united states by the FDA four years ago. This procedure could become more common as the contact lenses improve and eye doctors become more comfortable with contact lens implants.

If you are looking for hassle free contact lenses that require little to no lens cleaning than daily disposable contact lenses could be the contact lens for you. They are also great for people who wear contact lenses and suffer from allergies. Some popular daily disposable contact lenses are:

He was born in Prostejov, Northern Moravia, and after a sickly childhood wanted to study mechanical engineering at university. A friend, however, suggested chemistry and about this time he developed an interest in politics. In 1936 he received his first doctorate and subsequently produced his first synthetic polymer in 1938-9. He then worked as an assistant to Professor Vototek until the closure of the Czech universities by the Nazis in November 1939.

After finishing high school, Wichterle decided to study at the Chemical and Technological Faculty of the Czech Technical University (now the independent Institute of Chemical Technology in Prague). He graduated in 1936 and stayed at the university until further activity was blocked by the Protectorate regime in 1939. However, Wichterle was able to join the research institute at Baja’s works in Zlín and continue his scientific work. There he led the technical preparation of plastics, namely polyamide and caprolactam. In 1941, Wichterle’s team invented the procedure to throw and spool polyamide thread thus making the first Czechoslovak synthetic fiber under the name silon (the invention came independently of the original American nylon procedure in 1938). Wichterle was imprisoned by the Gestapo in 1942 but was released after a few months.

Wichterle returned to the university after World War II to specialize in organic chemistry and was active in teaching and writing a textbook of organic chemistry. He was made the dean in 1952 of the newly established Institute of Chemical Technology in Prague. Six years later, in 1958, he was expelled from it in one of the political purges held by the communist chairmanship of the institute. A year later, he became the chief of the new Institute of Macromolecular Chemistry of the Czechoslovak Academy of Sciences (CSAS), which he joined in 1955.

In the institute, he planned to continue his research on the polymerization of lactams and on the use of thinly cross-linking hydrogels that he had patented earlier, in 1953, together with Drahoslav Lím. As the institute was only being constructed at that time, Wichterle carried out the first experiments at home. He succeeded by late 1961 in producing the first four hydrogel contact lenses on a home-made apparatus built using a children’s building kit (Merkur). Thus, he invented a new way of manufacturing the lenses using a centrifugal casting procedure. The CSAS inexplicably, and without Wichterle’s knowledge, sold the patent rights to the United States National Patent Development Corporation (and later even consented to cancellation of the licence agreements). Actual mass production of contact lenses took place mostly abroad, mainly in the United States.

Wichterle was dismissed as Director of the IMC in December 1969, this time for signing the "Two Thousand Words" — a manifesto asking for the continuation of the democratization process begun in 1968 during the Prague Spring. In essence, the "Two Thousand Words" was a call for the people of Czechoslovakia to hold their party accountable to standards of openness—not open revolution. Vaculik began with an assessment of how the nation had declined under the CCP, painting a picture of moral and economic decay in which workers made no decisions for themselves. Punishment by the regime included removing him from his executive positions and making his research more and more difficult mainly by cutting off contacts from abroad and limiting his teaching opportunities. Eventually he managed to get very short-term contract work at the IMC, quietly to continue his research. He successfully created a number of medical applications for hydrogels including implants to vocal cords, capillary drains for the surgical treatment of glaucoma, implants for the direct infusion of drugs to tumours, an artificial larynx, substitution of the vitreous body including instruments for its replacement, hydrophilised heart pumps, the production of Xerogel rods for contact lens lathing, toric contact lenses, gel inserts to bronchi for drug administration for asthmatics, veterinary implants for the synchronisation of rutting, and a number of other small services to medicine.

In 1990, he was made president of the Czechoslovak Academy of Sciences till the dissolution of Czechoslovakia and was the honorary president of the Academy of Sciences of the Czech Republic after that. In all he wrote six books, over 100 publications in scientific journals and held over 150 patents. He received a great many awards during and after his life. In 1993, Asteroid 3899 was named Wichterle and a statue was erected outside the IMC in 2005.

The Helmeted gecko, native to the west coast of Africa, has a very unique night vision system that allows them to see colours even at night. The key to this night vision has been shown to be a series of distinct concentric zones of different refractive powers. This multifocal optical system (light at different wavelengths is perceived simultaneously on the retina) is comprised of large cones and is more than 350 times more sensitive then humans. Unlike many vertebrates that have both cones and rods in the retina the Helmeted gecko, like other lizards, only have cones which are more sensitive to light.

Humans are only able to focus on one object at a time where as the helmet gecko can focus on a least two different object of similar distance. With the help of this research it is conceivable that in the future we may be able to produce a multi-focal contact lens.

While we wait for the contact lens manufacturers to create the next generation of multi-focal contact lenses you can save money now on contact lenses available today for people who need to correct Astigmatism.
