Coloured Contact Lenses

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.

Do you have trouble seeing up close? it is possible you have hyperopia. But it could also be presbyopia. The truth is they are similar optically but have very different causes. Because they are foundationally different, their treatment options will also vary.

Hyperopia occurs when the light that enters the eye can not focus on the retina, because the eye is to short, the light actually would focus behind the eye. This is caused when the eyeball is shorter than it should be. Hyperopia, similar to myopia, can occur at any age. Some childred will actually outgrow this condition, as they grow, so do their eyes. But if they do not, corrective lenses such as contacts of eyeglasses can be used to treat hyperopia. For low power hyperopes a set of reading glasses can correct vision. Corrective laser surgery is also an available solution.

On the other hand, presbyopia also causes people to have diffculty seeing at near, but is age related. It is caused by the lens inside the eye losing flexibility. The result is the same as hyperopia: poor near vision. In general, corrective lenses are used to fix this. reading eyeglasses , used to clarify objects up close such as text or computer screens, are commonly used. Another choice is contact lenses to produce monovision, when one lens corrects the distance vision, if needed, and the other lens corrects the near vision. Monivision users have to train themselves to see through this new optical system. Contact lenses come in a multifocal variety, correcting vision similar to progressive eyeglasses.

Hyperopia only effects some and it is possible to treat it with surgery. the condition of presbyopia is inevitable, and until recently, was not generally treated with surgery. When the lens inside the eye loses its ability to flex and adjust focus, seeing up close is extremely difficult, that is when it is time for treatment. Though surgery for presbyopia has become available, the overwhelming majority of sufferers still choose the option of wearing reading glasses. They are safe, they do not require an invasive procedure, and they are stylish. If you are suffering from presbyopia and you need to wear readers, you may as well find a pair that looks good too.
