Are you going into the world of contact wear? Many people who are in need of corrective lenses choose to wear contact lenses because they hate the comfort and the horrible look with glasses. Glasses slip under your nose, weigh on your ears and nose, and cause trouble shining with light. You must have special glasses or extra pairs to protect the sun from being blinded when wearing glasses. A contact lens allows you to get rid of this stuff and just correct the look. Most people will not even realize that you are wearing contact lenses because they are almost impossible to see in your eyes.
Contact lenses have changed since the 1950s. Hard contact lenses were the first lenses to be made. This type of contact lens is made of a glass material which makes it very hard and very painful for your eye colorblind contacts. Most people find that glass is the only way to go because of the uncomfortable materials and costs. After all, it was easy to scratch your eye with a hard contact lens when you tried to pull it out because of the hardness of the material. The glass material was soon replaced with a polymer-based product, making contact lenses a little more comfortable. However, limited oxygen flow to the cornea was causing vision problems, such as blindness in people who had been in contact for many years.
Now we have silicon hydrogel contact. This is called a soft contact lens. The material is similar to plastic and is easier on the eyes than their counterparts. It is also thin. This thin material bursts easily, but gives your eye more comfort. It is almost weightless material so your eye will hardly notice its presence.
With the introduction of silicon hydrogel contact lenses, we also have more color contact lenses available. You may have seen someone with violet, jade, yellow or red eyes. Color contact lenses are available to create the effect you want, but there are downsides. Color contact lenses limit the flow of oxygen when you have this type of opaque lens because the material is a bit heavy to create the effect.
Your contact lens is designed to fit your eye. An eye care specialist will measure your eye so that the right lenses are ordered to fit your eye. That’s why most people wait a week or more for their contact lenses to arrive. You can also have correction lenses for astigmatisms or bifocal contact lenses. Torque lenses are weighed from below to keep in touch with your eye and eliminate blurred vision. Bifocal contact lenses are available for those who need adjustments for near and far vision and do not want glasses. Your eye care professional will make sure you have the correct version of your contact lens.
