The Hargrave Eye Center’s latest post:
Contact lenses may have been around longer than many might think. Especially, when one discovers that the first contact lenses manufactured were in 1887. Those early lenses were made of glass, created to cover the entire eye, and, as one can imagine, were said to be terribly uncomfortable. This is a wide departure from the little plastic or silicon discs most people are familiar with. However, as contact lens technology has advanced the array options available grown.
There are three main types of contact lenses available, daily, weekly, and monthly. Daily disposable lenses are typically worn only for the day and then thrown away after you remove them. This type of lens is generally made of thinner material both to keep the costs lower and for easy disposal. The other two types of contact lenses are weekly and monthly disposable. Monthly disposable lenses were the standard for a long time and although that is not the case any longer, some people still opt for this version. Both of these options are made of sturdier material than the daily disposable lens type so that they may be used several times before they need to be replaced. Both of these options also require daily cleaning, storage and overnight soaking in solution.
There are a few factors that one needs to consider if they decide to wear contact lenses; the prescription, sensitive eyes or conditions like astigmatism or dry eye syndrome, when they’ll be worn, where they’ll be worn, and cost. The other, possibly more important, are the health factors. Daily activity, as well as, one’s own tears can leave residue on contact lenses. This residue can include common things like dust, as well as, the proteins, calcium, and lipidspresent in tears. Although cleaning lenses may reduce these deposits or residues, it’s not always completely effective. For this reason, many patients prefer the daily disposable contact lenses both for hygiene and comfort. Disposing of contacts and all of the stuff that has collected on them throughout the day is much more convenient than the alternative, cleaning, soaking and storing. Daily disposable contact lenses may also give the benefit of less exposure to irritations and infections of the eye.
With so many choices available in the contact lens market there seems to be something to meet just about everyone’s needs. Remember to consider all the factors when working with your doctor in order to ensure the right fit for and for the health of your eyes.
