Coloured Contact Lenses

The functional advantages of contact lenses over glasses can be felt in areas like sports, working in humid conditions and also in occupations where glasses can be very inconvenient and may not be compatible when using equipment like special headgears.  Contact lenses also offer aesthetic advantages as they do not alter the image of the person wearing it.When contact lenses are worn correctly on the cornea of the eye, the vision is very similar to the natural vision.  The objects are seen in the right size and position without any kind of distortion of the image.  When glasses are worn, the distance between the glasses and the eye vary making the objects appear smaller or larger than the actual size, position etc.Contact lenses are not altered by bodily movements, as in the case of sports or similar kind of activities.They remain stable providing stable and clear vision to the wearer.  When glasses are worn, the vision is unstable while moving or running, in turn affecting the performance of the wearer.

Contact lenses provide a better and wider peripheral vision than the glasses.  Contact lenses move with the movement of the eyes and the wearer always looks through the clearest part of the lens called the optic zone.  When glasses are worn, it blocks the peripheral vision.  When the eyes move to the sides, the sight is far from the optic center leading to distorted and blurred vision.  Contact lenses do not steam up due to body heat or perspiration.  They also neither fog when exposed to cold weather nor get splattered in the rain.  Glasses on the other hand fog up and the wearer cannot see completely during rain pour.Contact lenses do not leave marks on the nose and are very comfortable to wear.  No pressure is felt on the ears, temple, or nose unlike the glasses.  Also glasses slide down from the nose during perspiration.

If you wear contact lenses then there are some steps you need to follow in order to prevent conjunctivitis (redness or swelling) or other symptoms that are caused by bacterial infections of the eye.
Basic contact lens hygiene is easy to follow with Optimum contact lens solution and will help to keep your eye healthy.

Prior to placing contacts in your eyes, you need to thoroughly dry and wash your hands. Under warm water, for thirty seconds hands should be lathered and scrubbed.

You may accidentally drop the lens down the drain and do not install contacts over a bathroom sink as sinks are full of bacteria. Instead work over a clean desk or table with a magnifying mirror. To avoid the mixup of your lenses by mistake, open the case that holds your contacts one side

After the first lens is in, do it again with the next lens. Dump any remaining solution down the drain and rinse the case with clean contact lens solution.

The tip of the optimum contact lens solution bottle must be touched to anything. The keep the bottle  and contents sterile will help.

Although you should never rub your eyes, this is especially true if your contacts are in. You might scratch your cornea and it could result in terrible injury. The contact solution never use water or saliva should only be rewated.

Watch your eyes to the accumulation of mucus like material. This is an indication of a problem with the contacts and they should be removed and kept out until the problem has cleared up. These give the eye time to heal and prevent contamination of the contact.

Every three months  the contact lens case  should be changed You must replace your contacts as recommended by a physician. Do not attempt to wear your contact lenses longer than recommended by your doctor.

The first contact lenses ever made were developed out of glass. After that, new types appeared, as the ones made of Plexiglas and the rigid gas permeable ones, but, nowadays, the soft contact lens is the most appreciated. Modern materials include silicon hydrogel or other plastic polymers like etalficon A, galyficon A, senofilcon A (used in the fabrication of Acuvue contact lenses). Rigid gas permeable contact lenses are recommended to the persons with dry eyes as these lenses contain no water that could evaporate during the wearing.

The wearing time

A daily contact lens is safer as the risk of infection is lower than at the long term contact lens. This type does not require cleaning, being single-use only. It is sterile. And it even keeps you away from spending money on cleaning or storage solutions. On the other hand, the extended wear type of contact lenses allows people to easily wear contacts for a longer period while allowing oxygenation (they usually have a high oxygen permeability rate). Some people prefer them as their convenience is obvious, but the risk of infection is higher than at the daily type of contact lenses due to the bacterial stagnation, dust accumulation and so on.

One of the most popular contact lenses brand in the world is Acuvue, produced by Johnson & Johnson’s subsidiary Vistakon Company. They provide both vision and esthetical contact lenses. They design disposable lenses, making types that are to be replaced every two weeks (Acuvue, Acuvue 2, Acuvue 2 Colors, Acuvue Advanced and Acuvue Oasys) or less (1-Day Acuvue). They’re also started making extended wear lenses.

Where to buy them from

Contact lens quality is very important. Low-quality contact lenses can damage the eye, causing irritations or hurting the eyelid or the cornea. Attention must be paid to the way the lenses are worn, kept and cleaned because, even if they are high-quality, they present different risks. So, the contact lens must be bought from specialised stores after consulting a doctor. Places where these items are available can be found anywhere as the contact lenses online are very popular. Another tendency is to acquire them from an on-line store. This method can even be less expensive and still offer the same quality. You just need the prescription. But be careful and only choose reputable stores. Your health is at stake.

There are some people out there who wonder why people spend money on expensive contact lenses or expensive glasses.  If you’re never worn glasses or contacts, then chances are that you have really good vision.  On the other hand, those that don’t have really good vision will need to get either contact lenses or glasses in order to have near perfect vision.

Even though they are great for your eyes, all contact lenses aren’t equal.  Although your doctor will help you select the best pair for your eyes, you should always know a little bit about the contacts that are available to choose from.  All contact lenses can be separated depending on their wearing schedule, purpose, material, and over transparency.

Materials
Contacts can be separated or best determined by their material.  Contacts are divided into two main groups – soft and rigid (hard).Soft lenses are gas permeable to a certain extent, being further categorized by the amount of water they contain.  Soft contacts can have either a low, which is less than 50 percent moisture, or a high moisture content, which is more than 50 percent.  Rigid or hard contacts on the other hand, are much harder in material and are considered to be gas permeable.

Wearing schedules
Hard contact lens can last for months, possibly even years before they need to be replaced.  Soft contacts on the other hand, have a schedule for replacement.  Some may need to be removed every 2 weeks, monthly, or even daily.  The more advanced contact lenses, such as Night and Day contacts, will allow you to wear them all day and all night.  Just like other contacts however, you will still need to clean them on a regular basis to ensure that the protein is removed.

Contact lens designs
The designs for contacts are divided into three areas - toric, spherical, and multi-focal.  Toric lenses are for those who have astigmatism, spherical is for short sightedness, and the correction of long sightedness, and multi-focal contact lenses are used in the correction of presbyopia.All three designs have their distinct purpose, and you should always ask your optician before you rush out and buy one.

Many different purposes
As you may already know, contact lenses serve different purposes as well.They can be optical, therapeutic, cosmetic or decorative.Optical are the most common, as they are for the correction of vision and anomalies you have may have.  Therapeutic lenses are normally soft contacts that serve to protect your cornea.  They are also used as a reservoir for certain medicines that are used to treat various cornea diseases and malfunctions.
