The human eye is commonly considered as the most advanced digital camera in the world. In addition, it usually indicates some diseases in other parts of the body. However, the eye will unexpectedly loose it elastic nature as people age. Presbyopia is such a consequence of this change in the eye.
This eye problem will gradually affect a person’s focus ability. As a result, presbyopic patients become unable to see near objects. Those elder ones with presbyopia can benefit from bifocal lenses, which have a lower section for near reading and an upper section to see objects at a distance.
However, there are many eye conditions that may influence the selection of contact lenses, including cataracts, glaucoma, trachoma, acute conjunctivitis, eyelid infection, astigmatism, color blindness, inflamed or water eye and so on. With certain of these conditions, some people may be confused to choose contact lenses or eyeglasses.
Actually, it all depends on individual type of eye infection. Without the consideration of personal eye condition, contact lenses and eyeglasses are both OK that they have both advantages and disadvantages.
Contact lenses usually require wearers to observe certain precautious daily rules and regulation. Certain factors such as cleanness and disinfecting must be carefully examined before contact lens wearing. Unlike contacts, eyeglasses require no special treatments on lens observation. In addition, eyeglasses do not react to the wearers like contact lenses.
There are still some detailed differences between contacts and glasses. Contact lenses are more expensive and require special training from the doctor as well as special storage to prevent infections. In contrast, eyeglasses require no special training and can be used for a longer period of time.
Nowadays, many young girls and ladies use contact lenses to gain extra fashion and good looking. This application is believed to cause more eye problems. All in all, eye health is more important than fashion.
