Not having 20/20 vision is definitely one of life's inconveniences, that's for sure. A clear vision is necessary for us to perform most of our daily activities, and if we don't have it naturally, we have to use certain accessories such as prescription eyeglasses or contact lenses to help correct the problem. Although they are quite effective in making us see clearly, they do come with their own disadvantages. One is the social stigma associated to wearing eyeglasses. With most affected people requiring correction from a very young age, they can be the object of playground bullying, taunting, and name-calling, and this can really affect their self-esteem and development.
Another problem associated with these correction lenses is that, despite their ability to help us do the daily activities we need, they can also, ironically, be in the way. In athletics, it is just not possible to take part in a contact sport like boxing or football while wearing glasses, so if wearing the alternative (contact lenses) is not recommended for you for some reason or other, you will be forced to play the game with uncorrected vision-and with that, the game could easily be compromised, especially if your natural vision is far from 20/20.
Another concern faced by these visually-challenged individuals is that, even if they are amenable to wearing contact lenses, wearing them too long could end up causing extreme dryness to the eyes and, sometimes, even to infection. Basically, it is not recommended that you wear your contact lenses for more than 12 hours in a day and for more than 5 days in a week. Your eyes need to rest from these “foreign” materials.
Given these so-called “setbacks” found in these conventional solutions, there's a demand for better and surer answers to the problem. Laser eye surgery aims to correct the visual discrepancy permanently, so you never have to wear corrective lenses ever again. Such assurance allows eye surgeons to charge an arm and a leg for this treatment, so not everyone who wants it can actually afford it.
For such people, they've now turned to another, more recent alternative: orthokeratology. (Check out orthokeratology in nospecs.com.au.)It is a system where you are made to wear a special pair of rigid lenses at night. These lenses can actually change the shape of the cornea, which then leads to corrected vision. They are customized to answer your cornea's particular needs. The idea behind this is that by wearing it during the night while asleep, you can do your day-to-day activities with good vision without having anything in the way. However, studies have shown that it only corrects the vision for eight hours, so if you require clear vision still after that, you have to wear your usual corrective lenses again. Another concern associated with this new system of correction is that you're required to regularly see your eye specialist. Regular check-ups help evaluate how the system is working (or not working) on your cornea; sometimes, adjustments have to be made to get the best results.
It's good that we live in a time where technology is always out for finding more solutions to our existing concerns. Know the pros and cons of these four options in relation to your own specific needs, so you can find the solution that best applies to you.
