natural eye colours
More and more people have started having problems with their eyesight due to the increasing time which they’re required, or choose to spend in front of laptop and computer screens. As a result, there are more and more people who have to choose between wearing eyeglasses or contact lenses.
Contact lenses are thin lenses which can be placed directly on the surface of the eyes, in order to correct eyesight or for cosmetic purposes. Worldwide, approx. 125 million people use contact lenses, either as an alternative to wearing glasses or in order to change the appearance of their eyes. Medically, wearing contact lenses gives better peripheral vision, they do not collect moisture in the form of condensation when moving between environments of different temperatures and they are known to be more efficient at correcting certain eye problems than glasses. They can be worn with sunglasses, goggles, etc. without problems and are practically impossible to notice by others.
When looking for contact lenses online, you will also find a large number of coloured contact lenses. These can be either cosmetic or corrective. Regardless of their purpose, they are meant to cover the iris, thus masking the colour of the eye and “replacing” it with the colour of the lens. This does not impede vision in any way, as they align perfectly with the pupil.
While early models were made of glass, and were not comfortable enough to gain widespread popularity, modern ones are made from silicone hydrogels. They’re soft and light and much more comfortable, even if worn for a whole day. As far as their wear schedule goes, contact lenses can be designed either for daily wear or for extended wear. Daily wear means that they must be removed at night, in order to allow the eye to breathe. The extended wear ones have a high oxygen permeability and can be worn for up to six consecutive nights, without causing any problems.
Contact lenses must also be replaced regularly, again depending on their type. Single use lenses must be replaced daily, while others are designed to be replaced every two or four weeks. Not replacing them on time can cause them to gather allergens and germs and can cause eye irritation or even an infection. They must also be thoroughly cleaned and disinfected on a daily basis.
There is a nearly endless variety of colours to choose from, ranging from contact lenses which perfectly imitate natural eye colours, to electric blue, pink, grey, white, black and many more.
Always make sure when buying contact lenses online, that the site sells quality products and always consult your eye specialist before starting to wear them.
