Disposable Lenses - By: arun1

Change is constant. The way the world is changing is unbelievable. What is trendy now becomes obsolete, what one thinks to be latest turns out to be outdated in no time. Large round spectacles came in to help people with imperfect vision. Soon these large specs were modified to suit the trend. They came in assorted shapes, round, oval, rectangular and etc. Then came the contact lenses that revolutionized vision correction. People with impaired vision got a new lease of life with them. They were excited with this new way of vision correction. They could do everything that others do, without worrying about their glasses. Vision correction without the hassles of glasses and spoiling natural look was the “in thing”.

The lenses how much ever comfortable have their own problems, maintenance, regular cleaning, proper preservation are some of them. To reuse them the user had to keep them dipped in the sterile solution overnight and had to carry the liquid along with the lenses. Though more comfortable than glasses they were not perfectly comfortable. The user always felt them on their iris. Impeccable comfort was yet to be achieved. Then came in the disposable lenses. These have a lifetime of a day and are to be disposed off after that. Water constitutes more than half of the composition of these disposable ones making them even more comfortable to wear and gentle on eyes. The vision correction is the prime purpose and it is achieved without any compromise. These lenses are also believed to maintain optimum moisture level in the eyes so that they don’t dry off and start itching.

Disposable lenses can be used by people with both near and farsightedness. Astigmatism and presbyopia can also be corrected. People with perfect vision can also use them to protect their eyes while working in dusty or smoky environment. Also allergic eyes get the required protection behind them. Another specialty is their permeability to oxygen. The material allows oxygen to pass through. Constant oxygen supply keeps the retina healthy and avoids irritation. Due to this the user hardly feels its presence on the iris. Naked eye comfort is achieved with them. A whole day of exposure to dust and pollution results in deposition of unwanted particles on the lens. Particles build up on the lens if it remains dry. The daily disposable keep the eye moisturized and attract less dust.

The major advantage that the disposable lens has over other lenses is that of maintenance. The user need not clean the lenses everyday as they are meant for a day’s use only. In case of traveling there isn’t any necessity to carry the cleansing agent. Every morning take out a fresh pair and throw them off at the end of the day. The user need not clean the lenses again and again as there is no need to do so. Though these lenses have high durability they are not to be used for more than a day. This may cause serious damage to the eye. These lenses come in a 30 or 90 lenses pack. They may be a little harsh on your pocket but are worth the extra buck. The comfort offered by them is priceless.
