Now when they remove the cloudy lenses in Cataract Surgery they replace them with plastic lenses focused for far vision, so you will need glasses for near vision.

Other people just carry prescription near vision glasses for when they need to look at things close up but normally wear no glasses at all.Years ago (before they began putting in plastic lenses) everyone needed glasses all the time after having Cataract Surgery, because there was no longer any lens in the eye to focus the light.

Fashion frames are quite common today. You can change your clothes, shoes, purses, make-up to suit your mood-- so why not glasses. Have fun with with fashion frames to give yourself an easy makeover.

Are Contact Lenses Right For You?
Contact lenses have been garnering more and more popularity as time goes on. When compared with traditional glasses, contact lenses are incredibly convenient in many different situations.

They are much more practical in various sports, and they are not affected by the weather as glasses are. Furthermore, certain vision conditions such as aniseikonia can only be corrected with the use of contact lenses. Contact lenses can be obtained through any licensed optometrist or opthamologist. These professionals will begin by assessing your prescription needs and investigating the condition of your eyes in order to ensure that they will be able to withstand regular contact lens usage. He or she will then present you with the type of contact lens that is expected to be most suitable to your personal vision conditions.

It is true that some health issues can result from wearing contact lenses. The majority of these problems occur when the lenses are worn in excess; for instance, wearing your contacts overnight is strongly discouraged and can lead to many vision issues. Poor hygienic practices such as the failure to wash your hands before touching your eyes can also lead to vision damage. Vision issues commonly associated with the usage of contact lenses include damaged corneas and eyelid inflammation. However, the majority of people who wear contact lenses will not experience any problems with these products so long as the lenses are used in a safe and responsible manner. Contact lenses confer many benefits on the wearer. When compared with traditional glasses, contact lenses are consistently considered to be the more convenient and more practical choice. Although your specific vision conditions and lifestyle practices will determine the best vision correction method for you, most people would find it beneficial to research the values of contact lenses in their everyday lives.

Considering contact lenses Read on for helpful information you need to know.?
Contact lenses, also known as corrective lenses, cosmetic lenses, therapeutic lenses, or simply contacts, are used to correct deficiencies in vision. In many people, there is a disparity between the refractive strength of the eye and the length of the eye which causes a refraction error. A contact lens counteracts this mismatch and allows for accurate focusing of light onto the retina. Some conditions contact lenses can correct include myopia (near or short sightedness), hypermetropia (far or long sightedness), astigmatism and presbyopia. According to some estimates 125 million people use contact lenses worldwide (or 2 per cent of the population) including 28 to 38 million people in the United States and 13 million people in Japan. Compared to glasses, contact lenses are less disturbed by inclement weather, do not steam up, offer the wearer a wider field of vision, and are more appropriate for participating in sporting activities. Some people use cosmetic contact lenses in order to change the appearance of their eyes. Cosmetic contact lenses may also correct the wearer’s vision however some blurring or obstruction of vision may take place due to the color or design. The Food and Drug Administration (FDA) labels non-corrective cosmetic contact lenses “decorative contact lenses”. There are also differences in the length of use of different contact lenses. Daily wear contact lenses are designed to be taken out before going to sleep while extended wear (EW) contact lenses are developed for continuous overnight wear, usually for six or more consecutive nights (although some lenses, referred to as continuous wear (CW), allow for even longer use up to 30 consecutive nights). Generally, extended wear lenses are discarded after the specified length of time. Remember that your eyeglass prescription is different from the one needed to obtain your contact lenses. You will need to see a licensed eye doctor for an examination that will result in obtaining your contact lens prescription. U.S. law provides consumers the right to obtain a copy of their contact lens prescription and to fill that prescription at the provider of their choice. Roughly 5% of contact lens wearers each year suffer complications due to their contact lenses. The majority of these issues are caused or related to excessive wear of contact lenses, particularly overnight wear.
