The Advantages Of Contact Lenses Over Glasses
Contact lenses are optical medical devices, just as spectacles are, and often provide cosmetic and optical advantages over them. The more than 35 million people in the United States who have opted for contact lenses over the use of glasses have done so because of their convenience, and cosmetic value. Many people initially feel discomfort when starting to use contact lenses, but the benefits of using them far outweigh these minor discomforts.
The Short History Of Spectacles
The invention of spectacles has greatly influenced progress in the arts and sciences, yet it is not very clear who invented this instrument. In 1270, Marco Polo saw elderly Chinese using this device, which they claim to have originated in Arabia in the 11th century.
The spectacles evolved in the western world from the late 1200s onwards, with riveted spectacles used by monks and scholars, who held the lenses in front of there eyes, or balanced them on their noses. The invention of the printing press in 1452 encouraged the mass production of spectacles, along with the growing popularity of books. For the lower and middle classes, there were spectacles mounted in wood, horn, bone, etc, whereas the upper classes used hand held spectacles in gold or silver frames.
The significant advancement in frame design occurred in the 1600s, with rigid bridges that allowed the spectacles to remain in place. In the present times, there has been a tremendous progress in frames and lens acuity, with the spectacles, whether plain or prescription, becoming a fashion statement.
The Short History Of Contact Lenses
If you are of the view that contact lenses are a new invention, you are way off the mark. Leonardo Da Vinci first described and sketched his ideas of contact lenses way back in 1508! However, it took more than 300 years to fabricate and wear them.
Swiss physician A.E. Fick and Paris optician Edouard Kalt are credited with fitting the first contact lenses, in the late 1800s, for myopia and hyperopia. These heavy glass lenses could be used for a few hours of wear only.
Plastic came into use in 1936, when William Feinbloom, an optometrist in New York, made contact lenses with the central portion of glass surrounded by plastic in the periphery that covered the sclera. 1948 saw a Californian optometrist, Kevin Tuohy produce contact lenses completely made of plastic.
The same year, George Butterfield, an optometrist from Oregon, improved upon Kevin Tuohy’s design with lenses that matched the shape of the cornea, and would not easily pop off. These lenses have evolved to the present soft contact lenses, which are worn by more than 90% of the contact lens wearers in the United States.
Contact Lenses vs. Glasses
Contact lenses offer functional advantages over glasses in areas, such as sports, work – in humid environment, and in occupations where spectacles are inconvenient and not compatible with the equipment used, such as special headgears. Let us look at some of the advantages that contact lenses offer over glasses:

The Advantages Of Using Disposable Contact Lenses
Wearing contact lenses is an alternative for those who are having eye sight problems. Those who don’t like the image of them wearing a pair of spectacles in front of the mirror, contact lenses are the way to go. Wearing them won’t change the way you look in public, if that bothers you so much.
There are many types of contact lenses in the market nowadays whether it’s soft, gas-permeable, disposable, daily-wear, normal or coloured, they are there for you to choose the ones that suit your needs. One of the best types of contact lenses that you can pick is the disposable ones.
The advantage of using a pair of disposable contact lenses is that you are minimising the risk of getting an infection on your eye. As most of us know, wearing contact lenses can expose the user to eye infection if not properly managed. You have to clean and properly store the contact lenses in order to reduce the risk. Prolong usage of the lenses can expose them to bacteria infection.
Protein and lipids, the substances produced naturally by our eyes can build up on our lenses and if not cleaned properly, can make our eyes prone to infection. In addition, if the lenses are not stored well, dust and other debris floating around in the environment can certainly get into contact with the lenses which in turn might harm your eyes.
By using disposable contact lenses, you are actually using completely sanitized contact lenses out of the box. After using the lenses for one whole day, you just throw them away and use a new sanitized set next time. No deposits or dust contamination to worry about.
Subsequently, if you are not using disposable contact lenses, one of the daily routines that you have to do is to clean and store the lenses properly to avoid contamination. This is absolutely a hassle to most people, especially if you are on the move and need to get ready quickly every morning. You might not have the time to sit down and clean your contact lenses everyday, after and before going to bed.
However, by using daily disposable contact lenses, you can practically forget about having to manage the lenses everyday. Just use them out of the box and at the end of the day, throw them into the bin. No extra time taken from your precious daily timetable.
Disposable contact lenses are also a great solution for those who do not wear contact lenses quite often. Some people prefer using normal glasses than contact lenses for some reason and they opt to wearing contact lenses on certain occasions only, for example when they are doing some sport activities which might not happen everyday.
On those occasions where wearing glasses is not appropriate, wearing contact lenses is the only solution, unless they prefer doing sports with blurred vision! It might not be a good idea to have daily-wear contact lenses due to the fact that they only wear those lenses occasionally. Hence an ideal solution would be to have disposable contact lenses, perfect for those types of situation.
If you’re looking to buy contact lenses, make sure you know what’s the purpose of having one. Disposable contact lenses certainly have several advantages over daily-wear or extended-wear contact lenses. In most scenarios, wearing disposable contact lenses is certainly a clear solution over other options.
