Here's looking at you

Ask someone to touch their own eyeballs and the common response would be nothing short of disgust, outrage or complete disbelief. Yet to those of the population who are contact lens wearers this is an everyday practice. I admit that on first being fitted for contacts nearly 21 years ago I found the process very, very unnatural and difficult. Some dexterity and patience is needed to go through the extraction of a new lens from its foil sealed saline solution packaging and balancing the floppy disc on the tip of a finger before careful negotiation onto the eyeball. There is a split second when the elasticity of the actual lens switches allegiance from fingertip to eyeball followed by a slight antiseptic type stinging and smarting before sight is returned in full definition and clarity. I do not mean to discourage those thinking of taking up lens wearing because it is a great and liberating thing and the progress in the technology of lenses has been remarkable. I remember a conversation with a former colleague who had some of the first commercially available lenses. These were hard and inflexible discs made out of perspex. The manufacture was crude and rough with a thick cross section of plastic and a wide outer edge so much so that they had to be hand finished in the factory by abrasion with emery paper to improve the fit and comfort. I cannot imagine how uncomfortable these must have felt attached to the eyeball but many wearers will have endured the pain and suffering just to be in the first new wave of fashion. My first lenses had to be sterilised between periods of use in a small portable plug in unit and with regular check-ups for any irritation, damage or infection which tended to be an inevitable feature in those early days. Within a few years the concept of daily lenses was introduced and the next generation were light, permeable and also with UV protection. I did exploit the advances in technology by keeping my lenses in for very long periods and also, inadvisably, sleeping with them still in place. Being an emotional person my frequent welling ups and tear production obviously helped to keep my eyes moist and the lenses firmly adhered to allow me to ignore the explicit instructions of the manufacturers and my Optician. I have very rarely lost a lens either from it simply falling out or from a mysterious disappearance where I suspect it just curls over and shrivels up and retreats to that space between the back of the eyeball and the brain. The latest lenses are not at all discernible when worn and on a couple of occasions I have actually tried to put in a new lens on top of an existing one not realising that there was one already in position. In the two decades of wearing lenses my regular check-ups show that my vision has remained fairly constant which is impressive given the potential for age related wear and tear and other medical and physiological influences to impair sight. My former optician, or whatever specialist term now applies, championed the cause for the study of the health and welfare of the eyes as an indicator of other bodily ailments and although he did not flag up any warning signs in my case he was able to alert other patients to problems of cholestrol and potentially debilitating illness to be brought to the attention of Physicians and other Health Sector practitioners for further diagnosis and treatment. The gift of sight is very precious and only really appreciated when it starts to become noticeably impaired or compromised. Sat in the opticians waiting area just today I was entertained and informed by the screening of a short presentation on the miraculous and wondrous composition and operation of the human eye to an extent that I had not really realised or appreciated. Perhaps I will take out my longstanding current lenses tonight, after all they are about 4 weeks old and a bit crusty although being a great fanof this optical marvel I am reluctant to admit to this readily or in polite company.
