Contact lenses normally used for the vision corrective purpose the same way a pair of glass does. It can be used for cosmetic purposes to change the color of the eye. These are light weight and are not visible. Many lenses give a UV coating to protect eyes from the ultra violet radiation. Around 125 million people wear contact lenses world over. 30 million people in USA are in the habit of wearing contact lenses.
With the creation of contact lens many people have switched over from regular glasses to contact lenses. The basic reason of the changeover is because contact lens does not disfigure your face and coolly fit into the cornea. During rainy season or wet conditions contact lenses are best to use instead of glasses as the glasses bet wet during this period and frequent cleaning is necessary.
The other clinical factor is the glasses keep a distance from the eye whereas contact lenses exactly fit to the cornea providing a clear visibility all around you. This is more helpful in sporting events and games as well as driving where you require perfect all round visibility. The glasses on the other hand because of their inherent drawback cannot give a perfect peripheral vision.
The other difference between them is the glasses come with a frame which is fitted to a pair of lenses. The contact lenses have no such obstruction as it directly fits into the eyeball. You do not have to periodically adjust frames to fit to your nose and ear. The difficult part of glass wearers is that they have to keep an additional sunglass to protect their eye whereas persons wearing contact lenses have ample choice and selection of sunglasses. The glasses may not suit on certain occasions and may not go with your formal dress for those occasions.
The major difficulty which a person confronts in glasses is its weight. The weight again increases with the design of the frame and the corrective lens whereas in contact lenses the weight factor is almost negligible.
While discussing the difference between glasses and contact lenses we find they have certain qualities in common. Maintenance and the cleaning is required for both of them. In contact lenses the cleaning is bit tedious as it has to soak in solution and perfectly cleaned before putting it on the eyes. You may have to use additional eye drops if your eye dries out.
Nevertheless both the varieties of items are affordable and it is worth spending because it is your eye which you are caring for. Considering the overall difference contact lenses have more plus points over the glasses. To opt for contact lenses take the advice of an ophthalmologist regarding which contact lens will be suitable for you. Contact lenses are of two types, disposable and cleaning lenses.
