A Clear Alternative to Eye Glasses
buy eye glassesWhile there are some fashionable eye wear frames available for prescription glasses, those who require corrective lenses to improve vision may sometimes find wearing eye glasses irritating. Contact lenses offer the freedom of corrected eye sight without having to shift around eye wear from slipping on the nose, or clearing off the lenses when it is raining or snowing. Many who wear prescription eye wear also have the option of wearing contact lenses, which are usually soft and made of silicon and attach directly to the eye. For fashion conscience customers, there are also some lenses that offer different shades and can change the appearance of the eye to green, brown, blue or aqua.
Consultation Determines Needs
Like with an eye glasses fitting, a reputable optician will offer a free consultation to determine the customer's needs. Some considerations will take place like eye shape – some customers may not be able to wear contact lenses for example if they have astigmatism. The shape of the eye in this condition is affected and the contact lens will not sit on the eye ball properly, thus unable to correct vision properly. However there are some with mild astigmatism who will still be able to wear contact lenses, so check with the optician on this as a lot will depend on the prescription.
A contact lens purchase should include a starter kit for the customer, and check-ups to ensure the lenses are fitting and working properly.
Some contact lenses are yearlies – by this the customer uses the same pair of contact lens each day for about a year's time. A more popular choice for many is disposable contact lenses. They are a more convenient method for contact lenses as it eliminates the need of daily cleaning. At the end of the day, simply throw out the lenses that were worn that day, and put in a new pair in the morning. No hassles! Over time, yearly contact lenses can develop protein build-up on the lenses that must be cleaned with additional product as basic saline solution will not cut it. With disposable lenses, this is also not a problem as the lenses aren't worn long enough to cause this build-up making it healthier for the eye over time. Lastly while it can seem a little more costly to spend money on changing lenses each day, this money can save you on cleaning costs throughout the year offering additional comfort for a reasonable price over time.
The Difference Between Hard and Soft Lenses
Contact lenses come in two different types – semi-rigid gas permeable (RGPs) and are made of a plastic material, although early lenses were actually made of glass. Benefits of these lenses include keeping their shape more so than soft lenses. Due to their composition, they have the ability to affect a wider range of eye conditions than soft lenses do. However, the wearer is aware of them more so than soft lenses and as a result are generally not as comfortable. Soft lenses are much more popular. Most wearers do not even realize they are wearing them, of course until sometimes dust can fly into the eye causing discomfort. However due to the nature of the silicone in the soft lenses, they can absorb more impurities which cause eye irritation more so than hard lenses. The consultation will advise which lens is more suitable for the customer's needs.
