Eyeglasses: A Solution to Eye Problems?

Anybody suffering from eye-related problems, both physical and medical, knows that squinting, headaches and/or eyestrain is just not pleasant - not to mention that itching, scratching and dryness that occurs when you are not taking care of your eyes properly.
Firstly, let's start with the basics - near-sightedness and far-sightedness; also known as myopia and hyperopia. In short, near-sightedness or myopia, is defined in lay-terms as things in the distance appear blurred and one can only see clearly (or relatively clearly) from up close. The first signs of this are squinting; eye strain and headaches. A simple fix is a pair of
prescription glasses.

On the other hand, far-sightedness, or hyperopia is when people can see distant objects clearly but objects close up are blurred. If you are farsighted, you may have eye strain, headaches and often feel like you're going squint when you work with things close up. For both ailments, prescription lenses that are made up accordingly to your specific needs and specific strengths, are the perfect solution.

Going one further, people - both farsighted and nearsighted - may also suffer from something called, ‘astigmatism' which is basically when your cornea is curved (in the shape of a football rather than the shape of a basketball) and therefore, you see things blurred because your eye cannot focus clearly - no matter what the distance. This is often an inherited problem and not something that can be prevented. In addition, the strength of the curve may increase over time, so this needs to be tested at every optometrist visit. Again, prescription eyeglasses and prescription sunglasses, are a great solution! Your doctor may prescribe glasses with no sphere and only correction for the astigmatism which will be indicated in your prescription's cylinder and axis.

Moving along, presbyopia is an eye problem most commonly occurs in the middle age years - around age 40, whereby one can see well at a distance, but cannot focus on objects close up. Where this is different to far-sightedness is that people require the ability to see close up and far away in one instance. Therefore, multifocal glasses are produced with an inner changing gradient of lens power that is produced according to the wearer's specific needs. In all progressive glasses, the gradient begins with the wearers distance prescription and then moves down to the wearers maximum prescription needs. Therefore, the wearer will have one prescription at the top part of the lens and another further down, in the case of
bifocal glasses; whereby with other multifocal spectacles such as trifocals, the lens will include three different strengths.
