Pros and Cons of Wearing Contact Lenses

Those who have been to an eye doctor before are most probably familiar with what contact lenses are as a rule. This is different however for many who are newcomers to getting their eyes tested or who have been given a prescription for contact lenses or eyeglasses by an ophthalmologist or optometrist for the very first time. Therefore they need to be educated in contact lenses 101 personally and come to know these corrective tools for eye problems per se. Because it is by knowing these eyesight enhancers intimately that one can choose the right pair for their prescription overall.

You may wonder, ‘What are contact lenses’? They are small plastic discs that are designed for the purpose of correcting eye problems. Some of these eye problems include nearsightedness, farsightedness, astigmatism, and for those who have had surgery for cataracts in some cases. These lenses are used for three different purposes and these are for corrective, cosmetic, and therapeutic reasons. The lenses are usually placed over the cornea of the eye. They float freely on a film that consists of tears that is located in front of the cornea. Who invented these invisible corrective eye tools? It was by a Czech chemist whose name was Otto Wichterle and he also came up with the first gel that accompanied them as well.

Contact lenses have many advantages over conventional eyeglasses. Not only are they lightweight, but they are also almost invisible to the naked eye. Many of the commercial lenses have been given a tinted blue so that they will be easier to see as they are being cleaned. This is mainly because they are so transparent and sometimes hard to keep an eye on at times. An ophthalmologist or optometrist will prescribe lenses that vary in accordance with the patient and the type of eye problem that they have.

Why do some people choose them over eyeglasses? Well, the answers are for various reasons. Many like these alternatives to conventional glasses for the fact that they supposedly make one appear way more attractive than someone who dons eyeglasses. Also they don’t get affected by weather conditions the same way that eyeglasses seem to. Glasses tend to steam up and this can severely limit one’s general range of vision. Eyeglasses also cannot correct certain eye conditions such as aniseikonia and keratoconus as does these lenses.

Contact lenses overall are way popular as invisible and corrective eye aids. People just seem to prefer them as opposed to eyeglasses in some cases and this is because of all the reasons that have been cited. Not only this, but they’re also comfortable and easy to wear. They also give one assurance that their eyes are being fixed bit by bit as they use them over the course of time.
