How to Choose Contact Lenses
How to Choose Contact Lenses? This is the most important questions especially for those who are willing to buy contact lenses first time. Are you just starting off with the use of contact lenses? Starting to use contacts may be intimidating, regardless of whether you’ve just found out that you need them or are making the transition from glasses to contacts.
The effectiveness of contacts is really great. In addition to this, using them is simple and risk-free! You will have a wide variety of options to choose from, which means that you will be able to get just what you are looking for.
But how do you decide which contact lenses should include on your list? Is there a kind that is superior to the others? You should listen to the advice of your eye doctor, but in the meanwhile, consider the following suggestions when selecting contact lenses. So, let’s discuss How to Choose Contact Lenses.
Types of Contact Lens
As with eyeglasses, there is a wide variety of options available for those who use contact lenses. It’s possible that you require lenses for nearsightedness, farsightedness, multifocality, or both. Bifocal contacts are meant to assist those who need vision correction for both far distance and close up work. Bifocal lenses are included in the category of multifocal lenses, however trifocal lenses and other kinds of lenses are also included. These may be obtained in either a soft or stiff configuration, and they facilitate a more natural transition from close up to far away vision.
If you have astigmatism, you may have the condition corrected using lenses called gas permeable lenses or toric lenses. Both are able to assist correct nearsightedness, farsightedness, astigmatism, and other vision issues simultaneously. Visit an eye doctor to get your prescription for lenses evaluated and determined. They will assist you in finding the lenses that will give you the clearest vision possible.
How to Choose Contact Lenses Color?
Not all contact lenses are clear. Some come with colours, either to assist you identify your lenses more readily or to produce an impact. Others come with colours for no particular reason. The natural colour of your eyes may be accentuated or altered with the aid of coloured contact lenses.
Some even have the ability to lighten the appearance of eyes that are naturally dark. Cat eyes are one of the many unusual effects that may be achieved using coloured contact lenses. You will still need a fitting and a prescription for them, despite the fact that they are perfect for Halloween or theatrical performances.
How often do you plan to put in your Contact Lenses?
Do you intend to put your contact lenses in every single day, or will you just do so on the weekends or for certain events?
The majority of individuals utilise soft contact lenses, which may typically be worn comfortably either continuously or intermittently, depending on the user’s preference. On the other hand, rigid gas permeable contacts can only be used comfortably on a daily basis if they are worn continuously throughout the day.
How to Take Care you Contact Lenses?
It is crucial that you use the contact lens solutions that are recommended by your eye doctor in order to prevent major issues that are associated with the usage of contact lenses. Some of these issues include fungal eye infections and corneal ulcers.
Even though disposable contacts have decreased the likelihood of getting some eye infections, proper lens care on a regular basis is still necessary to ensure that your eyes remain healthy when you use contact lenses.
Consider getting daily disposable lenses if you’d rather not have to deal with the hassle of washing and sanitising your contacts every single day. After wearing these so-called “one-day” soft lenses for the allotted time, you toss them out and replace them with a fresh set the next morning.
Is Sleepwear an Important Aspect of Your Routine?
Do you think it would be comfortable for you to wear contact lenses always, even while you sleep? Some contact lenses have been given FDA approval for use throughout the night because they enable significant quantities of oxygen to travel through them.
However, wearing contact lenses nonstop is not always safe for everyone. If you are interested in extended wear contact lenses, your eye doctor will assess how well your eyes handle wearing the lenses overnight in order to establish whether or not it is safe for you to do so.
Contact Lens Materials
When you are contemplating getting contact lenses, the first decision you will need to make is which lens material will fulfil your requirements to the greatest extent.
5 Different Type of Contact Lenses Material:
Hydrogels are the name given to the types of gel-like polymers that are used to make soft contact lenses. These lenses are very thin and flexible, so they may be shaped to fit perfectly on the cornea of the eye. Because hydrogel lenses are often instantly comfortable upon insertion, their introduction in the early 1970s led to a significant increase in the usage of contact lenses.
Hard contact lenses, which were manufactured of PMMA plastic. PMMA lenses required an adjustment period of several weeks on average, and a significant number of persons were unable to effectively use them.
Silicone hydrogel lenses are a more sophisticated form of soft contact lens than conventional hydrogel lenses. As a result, they are more porous, which enables even more oxygen to enter the cornea than regular hydrogel lenses. Silicone hydrogel contact lenses were first introduced in 2002, and they have since become the most common kind of contact lens prescription in the United States.
Gas permeable lenses, commonly known as GP or RGP lenses, are a kind of rigid contact lens that have the appearance and sensation of PMMA lenses, but they are porous and enable oxygen to flow through them. GP lenses are more pleasant than traditional hard lenses because they can be placed closer to the eye than PMMA lenses can. This allows the lenses to be worn for longer periods of time without discomfort.
Gas permeable contact lenses have effectively taken the role of nonporous PMMA contact lenses ever since they were first introduced in 1978. The vision provided by GP contacts is often clearer than that provided by soft or silicone hydrogel contacts, particularly if the wearer has astigmatism. When you initially start using gas permeable lenses, it normally takes some time for your eyes to adjust to them. However, following this first adaptation period, most individuals find that GP lenses are just as pleasant as hydrogel lenses.
The wearing comfort of hybrid contact lenses is meant to be comparable to that of soft or silicone hydrogel lenses. On the other hand, hybrid contact lenses are supposed to have the optical clarity of gas permeable lenses. A stiff gas permeable zone is located in the middle of hybrid lenses, and this zone is encircled by a “skirt” of hydrogel or silicone hydrogel material.
PMMA lenses are fabricated from a polymer known as polymethyl methacrylate (PMMA), which is also a clear hard plastic substance. In addition to its usage as a replacement for glass in shatterproof windows, this material is marketed under the brand names Lucite, Perspex, and Plexiglas. PMMA lenses provide outstanding optics, but they do not allow oxygen to pass through to the eye and may be challenging to adjust to.
How Often Should Your Contact Lenses Be Replaced?
Even when they are properly cared for, contact lenses (especially soft contacts) should be replaced on a regular basis in order to prevent the accumulation of lens deposits and contamination, both of which can raise the risk of eye infections. This is especially important for those who wear disposable lenses.
The following are the broad categories that may be applied to soft lenses depending on the frequency with which they should be discarded:
- Daily disposable lenses are ones that need to be thrown away after only one day of use.
- Disposable lenses
- Frequent need for lens change; throw away on a weekly or quarterly basis
- Traditional lenses, which may be reused, should be thrown out after six months or longer.
Gas permeable contact lenses are not need to be discarded as often as soft lens contact lenses because they are more resistant to deposits on the lens. GP lenses often have a lifespan of one year or even more before they need replacement.
Features of Contact Lens
Astigmatism correction using bifocal contact lenses. Because these sophisticated soft contacts cure presbyopia in addition to astigmatism, you may avoid wearing glasses beyond the age of 40 even if you have the condition known as astigmatism.
Contact lenses designed for dry eyes. Are your contacts too dry to wear comfortably? There are certain soft contact lenses that have been manufactured specifically to lessen the risk of dry eye symptoms that are associated with using contact lenses.
Lenses of various hues Many of the kinds of lenses that have been mentioned above also available in colours that may make the natural colour of your eyes seem even more vivid. For instance, if you have green eyes, you might have your green eyes appear even greener by wearing these coloured lenses. Alternate coloured lenses have the ability to completely alter the colour of your eyes, even turning brown eyes into blue eyes.
Special-effect lenses. Special-effect contacts, which may also be referred to as theatrical lenses, novelty lenses, or costume lenses, take the colouring process one step further and can make you appear like a cat, a vampire, or any other alter ego of your choosing.
Lenses for Prosthetic Eyes Additionally, coloured contact lenses may be used for applications that are more related to medical care. Prosthetic contacts are opaque soft lenses that may be custom-designed for an eye that has been damaged as a result of an accident or illness. This allows the deformity to be concealed while the look of the eye is brought closer to that of the unaffected eye.
Custom lenses. If you have tried conventional contact lenses, but they have not been successful for you, you may be a candidate for bespoke contact lenses. These lenses are created specifically for the shape of your eye and the requirements you have for your vision.
UV-inhibiting lenses. Some types of soft contact lenses provide your eyes protection from the harmful UV radiation of the sun, which have been linked to cataracts and other eye conditions. However, since contacts don’t cover the whole of your eye, you should still wear sunglasses that block UV rays whenever you go outside to get the most protection possible from the sun.
Scleral lenses. Scleral contacts are large-diameter gas permeable lenses that have been particularly created to cure presbyopia as well as keratoconus and other corneal abnormalities.
Myopia control contacts. In an effort to halt or at least significantly decrease the growth of nearsightedness in youngsters, researchers are developing specialised contact lenses.
What Kind of Contact Lens Would Be Best for You?
To begin, the issue that is causing you to have to wear contact lenses in the first place has to be addressed by your contacts. Your contact lenses should be able to correct your myopia, hyperopia, and/or astigmatism, or any combination of these refractive errors, such that you have clear vision with them.
Second, the lens should be a comfortable fit for your eye. Lenses are available in thousands of different combinations of diameter and curvature so that this may be accomplished. Naturally, not all lens brands are available in each and every “size.”
Your ECP is trained to assess the physiology of your eye as well as your vision in order to decide which lens most effectively fits the two requirements mentioned before.
Third, you can have another medical need that determines which lens type is best for you. If your eyes have a habit of being dry, for instance, your eye care professional may recommend a certain kind of lens.
