Contact lenses are special medical devices that customers are required to do enough homework before making a decision, which is true either for people who want to switch from eyeglasses to contact lenses or those go straight to contacts. Contact lenses come in various types and most of them require proper daily care and maintenance. Rigid gas permeable lenses, toric lenses, vial lenses and soft contact lenses are some of the types. Before purchasing contacts, a customer must have a thorough understanding of the differences among all the common lens types. There are also disposable versions of contact lenses. Except for factors involved in contact lenses themselves, there are still external factors that are worth equal consideration. Those factors include lifestyle, schedule and budget. Furthermore, the climate conditions in one’s local area are also decisive in choosing contact lenses. In some cases, weather in local place will affect the way lenses interact with the eyes. What’s more, the weather in a city or town that a person is planning to visit should also be under consideration. Among all climate conditions, dust flying through the air is the most bothersome. It has been widely reported by contact lens wearers that dust is the most uncomfortable weather condition. Hard contact lenses are extremely vulnerable to dust carried by gusty winds. Hard lens wearers will experience excessive pain in the eye. To make a compromise, they can wear sunglasses, which can prevent most dust from entering the eyes and touching the lenses. Another kind of weather factor is arid climate conditions. For example, a contacts wearer can hardly keep his lenses moist in deserts. The natural moisture provided by the eyes to the lenses will rapidly be sucked by the heat and dry air in arid conditions. Many people resort to rewetting drops to restore lens comfort in these conditions. Contact lenses actually perform better than eyeglasses in most severe weather conditions. Even in cold and rainy days, contacts will not get fogged as easily as eyeglasses. People are also needless to deal with bulky frames on the bridge of the nose. One point is worth enough attention that contact lens wearers should not keep their eyes open for extended periods.
