If you’re a contact lenses wearer, please tell me how often you replace yours, and if you have had any problems by using the case for more than 3 months. Thanks.

Soft contact lenses are flexible plastic lenses which absorb water in the eyes and become soft and hence are also known as hydrophilic. Soft contact lenses are made of plastic hydro gel polymer that consists of thirty-five percent to seventy-five per cent water.  

Soft contact lenses fit perfectly on the eye balls and are not felt by the user. They are used to correct vision and are better than rigid lenses because they fit exactly on the eye balls.  Soft contact lenses are used to correct near sightedness or far sightedness and also problems related to bifocal vision.

It is also possible to have a specialized type of soft contact lenses to reshape the cornea while wearing them during night time.  But the draw back is, they have to be worn compulsorily every night, to get a good vision the next day.  Since soft contact lenses blend well on the eye balls, the chances of dust particles entering the eyes are minimum.

Soft contact lenses are made up of a special kind of material to retain the moisture of the eyes and make the surface of the contact lens stay wet.  The main advantage of soft contact lenses over their other counter parts is that, they allow free flow of oxygen and are permeable thus maintaining healthy eyes. 

Though disposable, soft contact lenses are a little expensive, but they are preferred because they alleviate the need to clean the lenses and store them in a contact lens solution, specifically manufactured for this purpose.  Even in soft contact lenses colored lenses are available, which serve aesthetic purposes .When disposable contact lenses are used, the user has the facility of wearing them intermittently like week end or occasions.  There are extended wear soft contact lenses which are worn overnight for one week and replaced every one to two weeks.  But they have to be disposed in the prescribed time; otherwise it would be an invitation to potential disaster. 

The most common problems occurring for the wearer of soft contact lenses can be irritation of eyes and blurred vision.  These inconveniences should be evaluated in the initial stages. Upon removal of the contact lenses, if the blurred vision lasts for hours, then the medical practitioner should be consulted immediately.

The size of the soft contact lenses can vary from 13 to 14.50 mm and as they are thinner, they are almost weightless and the wearer will barely feel the presence of the soft contact lenses. Soft contact lenses tend to absorb the many kinds of pollutants like lotion or soap which may cause irritation to the eyes and are prone to be torn off. Nevertheless, it is advisable to consult the eye specialist before choosing the type of soft contact lenses.

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.

If you’ve ever seen a movie about vampires or monsters where people have oddly colored eyes, cat eyes or other types of eyes, you’ve seen special effects contact lenses in action. These contact lenses, rather than correct sight (though some are actually prescription as well) create a special effect in the eye.

These lenses come in a wide variety of types and are available to the general public. While certain special effect contact lenses are designed especially for a movie, you can also expect to find similar ones on the public market within a few months after the movie is released.

Styles of Special Effects Contact Lenses

There are so many different types of these contact lenses that you can really get any look you want. For some people, this means simply changing their eye color. Light eyes can easily become any color you like, from green to blue to brown or even purple. Dark eyes are more limited in the options, but can usually go with black, dark green and sometimes a dark blue or purple.

For more zany effects, there are plenty of other options. Everything from the very scary cat eyes or red hellish eyes to more benign smiley face contacts can be had. There are circuit board contacts, zebra or tiger stripes, and just about anything else you can imagine. There are even images available to place in your eyes, so you can have a tiny flower or mountain scene actually placed on your eye.

Not every special effects contact company will provide all of these options, but you’ll find that the catalogs of effects are quite surprising.

Why Use Special Effects Contact Lenses

For some people, it’s a matter of feeling better about themselves. If you don’t like your eye color, for example, being able to change it to something you feel is more acceptable can be a good boost for your self esteem.

For others, it’s about conveying who they are inside. Science fiction fans, for example, might want to use eye color and styles that represent their favorite sci-fi characters. Those who are fascinated by vampires may prefer vampire style eyes while those interested in technology might want to surprise their friends with circuit board eyes.

Special effect contact lenses are usually only used a handful of times. Some are actually one use only and they are completely disposable. This type of contact lens is ideal for Halloween parties or other disguises. If you are in need of a costume for a play, special effect contacts can also come in handy, as with role playing activities.

Should You Use Contact Lenses for Effect?

Not everyone is interested in using contact lenses. If you have eye problems, you might want to talk to your eye doctor before trying special effects contact lenses. They usually aren’t meant for long term use and if you aren’t accustomed to wearing contacts, it is better not to leave them in for very long. Two or three hours is the recommended period for beginning contact lens wear.

If you already use glasses or contact lenses, you can get special effect lenses as prescriptions, too. So, they would just replace your regular contact lenses. Otherwise, glasses can be worn in combination with the contact lenses, though some people find this ruins the effect they are going for. For simple color changes, however, it works fine.

Special effects contact lenses can be a lot of fun to play around with, but they are also very practical if you need a new look. Check out the different options available and choose the ones that suit you.
