How good or bad contact lenses are for your eyes are questions people often ask, and with good reason. Eyes are delicate and every care should be taken to ensure you don’t damage them. Thankfully contact lens technology is far more advanced than it was even five years ago and the safety of lenses is less of a concern if you ensure that you care for your lenses correctly.
Contact Lenses & Eye Conditions
There are some eye conditions which can be exacerbated by wearing contact lenses, though luckily these are quite rare and also very easy to diagnose. There are certain safety precautions which you should always take, such as not swimming or showering with your lenses in and never ever use tap water to clean them.
The reason for this is that there are unfriendly microbes in the likes of tap, sea or pool water which can fester between the lens and the eyeball. They can cause infections which, if left untreated, can result in serious damage to the eye and even loss of sight.
However, as gnarly as that sounds, contact lens care is pretty straight forward. So long as you avoid wearing lenses when you shouldn’t (when swimming and often when sleeping), only wear lenses for their specified amount of time and only ever clean and store them in the designated saline cleaning solution, such issues as I just described are practically impossible to occur.
Many eye disorders such as nearsightedness or farsightedness can actually be corrected by prescription contact lenses. They help diverge or converge light rays so the eyes can focus on objects either near or far. Of course, wearing prescription contact lenses should always be preceded by a visit to your optometrist or ophthalmologist, who will be able to test your eyes and ensure you know exactly which lenses are ideal for your condition.
Your eye doctor will also be able to advise you on which kind of lens is best suited for your eyes, as there are multiple options ranging from soft lenses containing water to harder lenses, usually referred to as Rigid Gas Permeable or RGP lenses.
It’s crucial to understand the kind of lens you have, as some are designed to be worn for a day and then discarded, others to be worn for anywhere between and week and year. Usually, lenses need to be removed every night before you got to sleep, but there are plenty of contact lenses options which do allow you to sleep with them in. Never sleep wearing lenses if they are not specifically designed for it though.
Colored contact lenses do not affect your vision but simply change the color of your eyes. They are made from the water-based soft lens material to help keep the eyeball moisturized, and should usually only been worn for a maximum of eight hours. The modern materials used for cosmetic lenses today are perfectly safe, though it can be worth a visit to the optician to check if you have any existing eye conditions which might be irritated by the wearing of any kind of contact lenses.
Even though colored lenses are not designed to amend vision disorders, they still need to be cared for as much as prescription contact lenses. They must only be handled with clean hands, and the lenses only cleaned and stored with the same saline cleaning solution that you would clean a prescription lens with. If you are looking after your contact lenses in the correct way, then you have little to worry about and you will find color contact lenses perfectly fine for your eyes even if you wear them every day.
