Colored contact lenses are now accessible with no prescription to use on Halloween to look like Lady Gaga, a vampire like Edward in the Twilight motion pictures, or perhaps to just make your eyes a enticing shade of blue to dress as a Disney Princess! Soft contact lenses are unquestionably the most commonly prescribed contact lens available. Manufactured of delicate, supple plastic, it is estimated that nearly 90% of contact lens wearers have soft lenses.
In 1971, Bausch & Lomb launched the original commercially obtainable soft contact lens. For years, this conventional soft daily wear lens was the lone type of soft contact lens available. This lens ideally was meant to last between six and 12 months and required daily cleaning and weekly enzymatic cleaning.
In 1981 the FDA approved the first contact lenses accepted for extended or overnight wear.
It wasn’t until 1991 that the first frequent-replacement contact lenses were available. Frequent-replacement contacts are typically replaced every one to three months. The next year, 1992, disposable contacts (disposed every 2 weeks or less) were put on the market.
In less than ten years, frequent-replacement and disposable lenses started to be the lenses of choice for the vast majority of eye care providers. At present roughly 75% of soft contact lens patients are wearing some sort of frequent-replacement or disposable lens. Frequent-replacement and disposable contacts are available for purchase as both daily and extended wear.
Soft Contact Lens Choices
As implied, daily wear contacts are removed and cleaned each day, while extended wear lenses can normally be worn continuously for up to seven days.
Disposable contacts are similar to any other disposable product on the market – thrown away after being worn, while the permanent contacts are cleaned and sanitized before reinserting the contacts.
Individuals who decide on extended wear should be conscious of the added danger of eye infections and complications that occur with sleeping in contacts.
A visibility tint is typically a light blue or green shade added to a lens, just to help you see it better during insertion and removal, or if you drop it. Since it is a extremely light tint, it does not affect your eye color.
An enhancement tint is a dense but transparent (see-through) color that is a little darker than a visibility tint. An enhancement tint will modify your eye colour. As the name implies, it’s meant to enhance the existing colour of your eyes. These types of tints are typically best for consumers who have light colored eyes and want to make their eye shade more intense.
When people think about coloured contact lenses they may not realize that color tints are deep, opaque tints that can change your eye color completely. For individuals with dark eyes, color tint lenses are what is needed in order to completely change the colour of their eyes. colour contacts (available without a prescription) come in a wide selection of colors and designs, including: black, red, green, blue, violet, white, cat eye, white spider web and many other fun or sexy designs . The middle of the lens, the part that lies over your pupil, is clear so you can see.
Costume or theatrical contact lenses also fall into the category of opaque colour tints. Long used in the movies (examples are the Incredible Hulk and Twilight), these special-effect contact lenses are now widely available and can temporarily transform the you into a Halloween vampire, ghoul, witch, cat or perhaps turn you into Alice in Wonderland, a beautiful fairy or princess.
A new trend is the circle contact lens. Made popular in the U.S. by pop star Lady Gaga in her Bad Romance video, circle contact lenses appear to be bigger because they are not only tinted in areas that cover the iris of the eye, but tinted prominently in the extra-wide outer ring of the lens. The result is the appearance of a bigger, wider iris.
