The moment you decide on giving up wearing eyeglasses, you will definitely begin looking for the perfect pair of contact lenses; either for daily or prolonged use.
Considering the wide array of options made available over the market, coming up with the ideal pair of contact lens is a quite difficult task to accomplish. To do this, you need to carefully consider certain factors such as price and design, so as not to waste time and money.
Options on Contact Lenses
Contact lenses come in different types and designs, allowing you to choose from a wide variety of selection in the market. You must be willing to spend time and exert effort in finding the contact lenses that would meet your needs, preferences and budget. For optimal use, it would be best to consult an ophthalmologist to detect for possible eye disorders such as presbyopia, stigmatism, myopia or hyperopia and consequently have them corrected.
The Advantages of Daily Contact Lenses
For those that are not entirely sure that they want to use contact lenses, going with daily contact lenses can be beneficial. If you want to use contact lenses just for a short time, daily contact lenses would make a great choice. Another advantage of daily-use contact lenses is that they are disposable after use, leaving you no worries about cleaning them. Prolonged-use contact lenses require careful cleaning and handling as they can damage you eyes and vision irreversibly. With daily-use contact lenses, you won’t have to worry about damaging your eyes.
Daily Contact Lenses are More Recommended for Use
Daily contact lenses are more widely used because they are much easier to use. Another reason is that compared to extended-use contact lenses, they are less expensive and more cost-effective; thereby helping you save money. If they are damaged, buying another pair is not a problem, since they are very affordable. They also require no maintenance measures since they are disposable after use.
If you’d like to replace your eyeglasses with contact lens, you have to consult your doctor first so they can determine the pair of lens that can maintain the functional integrity of your eyes and are affordable at the same time.
How do they work?
Contact lenses cover your cornea, with a supply of tears underneath. They maintain their positional integrity with the help of the pressure from your eyelids. When your eyes close upon blinking, the pressure exerted by your eyelids makes the lens slide along your cornea, which in turn causes the dirt accumulated in your eyes to be washed out with the tears.
Contact lenses are used for various eye defects such as presbyopia, astigmatism, myopia and hyperopia. In these visual disorders, the eye’s retina cannot focus light effectively. This will in turn lead to impaired or blurry vision. Contact lenses are then especially designed and created to correct these eye conditions.
In astigmatism, a lens is created to improve focus of light in the eye and eventually improve visual acuity.
In myopia (nearsightedness), a lens which is thinner on the center and thicker on the peripheries is required for the retina to efficiently process light.
In hyperopia (farsightedness) on the other hand, a lens which is thicker on the center and thinner on the edges is required for the retina to correctly process light.
Whatever their indications for use are, contact lenses are used to improve vision and maintain the eye’s function
