Perhaps you have worn spectacles since you were a child, or maybe you only begun to experience vision problems with age. Whatever the circumstances, most of us dislike the fact that our sight is not what we would like it to be, and that we need to wear corrective lenses.
These days there is a vast array of spectacles to suit everyone. However with recent advances in contact lenses more and more people are opting for these. In the past, many potential contact lens wearers, never actually took the plunge, but opted for conventional spectacles instead. Sometimes this was simply personal choice but, in a small number of cases, it was down to eye conditions such as Astigmatism. This no longer needs to be a problem though.
Hard or Soft Lenses.
Contact lenses are available in a choice of materials nowadays. Silicone polymer is stronger and used for hard lenses whilst plastic polymer, which is less durable but more flexible, is used to make soft lenses.
Soft lenses tend to be disposable and changed daily. However, it is possible to have soft contact lenses with a reasonable shelf life. Many lens wearers find that soft lenses are cheaper in the long run, and much more comfortable to wear, but there is plenty to consider before you make your choice.
Hard Contact Lenses.
Hard lenses can last many years, often longer than a pair of spectacles. You will need to follow advice though, on how to look after your lenses. This is important for the health of your eyes also.
These days there will normally be a pair of hard contact lenses suitable for most eyesight problems. Hard lenses do not dry your eyes out as much as soft lenses can. This is good news for contact lens wearers, such as menopausal ladies, who may be suffering from dry eyes anyway.
On the whole though, hard lenses can be a little more tricky to wear. They can take some time to get used to wearing and to placing on your eyeball. If you are anxious about getting contact lenses into your eyes you would probably be better off trying soft lenses.
Soft Contact Lenses.
Soft contact lenses are different again. Most wearers find that from day one these lenses are comfortable to wear. The flexibility of the material means that they will bend when you want them to and so are easy for you to get onto your eyes.
Soft lenses are not suitable for all eyesight problems. These lenses are also less durable than hard lenses, although they are usually cheaper. Soft contact lenses are either disposed of daily or each week.
Varifocal Contact Lenses.
Believe it or not it is possible to buy Varifocal contact lenses. These will correct near and long sightedness. Varifocal or Bifocal contact lenses are usually hard lenses.
The importance of a good eyesight test.
Eyesight is a precious commodity, which should be cherished and cared for. As such it would be foolish to wear inappropriate lenses. Even if you simply want to wear coloured lenses you need to have a good eye test. This will make sure that your eyes have no underlying health conditions, which may make the wearing of contact lenses unsafe. A reputable optician will also explain the difference between all of the lenses available and work out which are best for you.
A basic health and lifestyle history will compliment the eye test and enable the right choice of lenses to be made. If, for example, you have an overactive thyroid condition, contact lenses will not be suitable, and you will probably have to opt for conventional spectacles. However, with the vast choice of frames and styles these days your spectacles may be anything but conventional.
