Top Benefits Of Soft Contact Lenses

Soft contact lenses are the flexible plastic ones that absorb the water in eyes thereby becoming all the more soft. These eyewear fashion accessories are also popularly called as hydrophilic as they are specially made of the plastic hydro gel polymer which includes 35 to 75 percent of the water. Soft contact lenses can serve both as an eyewear and the eyewear fashion accessory for its users.

In the past, contact lens wearers had to use two separate solutions that one for lens storage and the other for lens cleaning. Thanks to scientific advances, there are multi-purpose solutions that combine both of the two duties.

Since the introduction of contact lenses years ago, the eye product has gone through various changes and innovations to meet the needs of the consumers. There are now more than ten types of contact lenses each with its own characteristics. You can get a prescription from an eye doctor and decide on your own which specific brand and type of lenses you want.

The following are the types of contact lenses you can use depending on your needs and preferences:

• Daily wear soft lenses – made of soft polymer plastic, these contact lenses allow oxygen to pass through providing a higher level of comfort than rigid gas permeable lenses. Disposable soft lenses fall also under this category. They are called daily wear contact lenses because they require daily cleaning. Although most daily wear soft lenses are disposable there are also those that can be worn for one whole year. Disadvantages of these types of lenses include: easy absorption of oils and lotions from your hand which can irritate your eyes and also less durability than hard lenses

This year (i.e., 2008) will be the 500th anniversary of the original conception of the contact lens. Its present form is the result of centuries of imaginative thinking, scientific reasoning and technological advances.

In 1508 Leonardo da Vinci became the first person to conceive of a contact lens. He did not propose this as a way of correcting vision, but as a way of understanding the manner by which the eye is able to preserve the visual clarity of an object as the object moves closer or further within the field of view. Leonardo da Vinci’s remarkable brainchild was not feasible at the time because of technological limitations.

The next development was a hypothetical method put forth by astronomer Sir John Herschel in 1827 for grinding and shaping them to match the shape of the surface of an eye.

As part of this methodology, Sir John Herschel suggested that a mold of the eye be taken in order to guarantee that their shape be a precise fit to the shape of the eye. Nonetheless, the technological ability to create a mold of the eye was not present during the first half of the 19th century.

Soft contact lenses are made up of flexible plastic called the hydrophilic. When soft contact lenses are used, they absorb water in the eyes (hence they are termed as hydrophilic) and become pliable and soft. The nature of the soft contact lens makes it possible to fit perfectly on the eyes. Soft contact lenses are popular because they are used in the correction of vision and the property to contour comfortably to almost all the eyeballs without any problem, due to the right fit of the soft contact lenses and as they do not pop up like the rigid lenses.

Soft contact lenses offer wide range of solutions to conditions like near or far sightedness, bifocal vision problems and colored ones. A specialized type of soft contact lens is available these days to even reshape the cornea during nightwear. This makes the wearer to get a clear vision without even wearing the contact lenses during the day. The main disadvantage is that it is not a permanent solution and has to be worn compulsorily every night for good sight next day. Soft contact lenses protect the eyes from protein or lipid deposits and bacterial or fungal growth.

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.
