Learn How To Choose The Ideal Contact Brands For You

By Millie A. MacDonald

There's no better feeling as compared to getting rid of a pair of "wraparound-your-face" glasses for contacts. For that couple of hours (or couple of days) you have them on, it's like your very own eyes are operating on their own. The secret to getting this kind of easy-breezy experience will be locating the contact brands that actually work well for you. Understanding the various kinds of contacts available can give you a better idea of which model will feel ideal.

Forms of Contacts

With so many contact brands out there, it's not easy to settle on which one to select. A great way to know which brand name to look for is simply by deciding what sort of contact lens you would like along with what type of lens the eyes require. While one particular brand name may focus on fitting a specific eye type, they may or may not provide the type of contact lens you would like. Generally, there are six types of contact lenses - * Non-reusable * Extended Wear * Silicone Hydrogel * Rigid Gas Permeable * Toric * Multifocal

Simply because of their convenience and all round health advantages, disposable lenses are the most widely used of the six kinds. Given that they're actually disposable, these lenses could be worn on an every day basis or for one to two week stretches based on the model. Unlike disposables, extended wear lenses may be worn all day long and all night long from 7 to 30 days, nonstop.

For the far more health-conscious contact lens wearer, silicon hydrogel contact lens are designed to allow for all-natural oxygen-air movement through the contact lens surface area. This kind of "breathability" factor keeps a person's eye cornea healthy whilst creating a secure fitted contact lens.

Rigid gas permeable contact lenses or RGPs work best for individuals needing a specialized prescription. Instead of the gentle, adaptable components found in soft lenses, RGPs are made from plastic materials so they're stiffer compared to soft contact lenses. RGP materials will also allow for ventilation through the contact lens surface.

Toric contacts may work best if you possess an irregular-shaped cornea, also referred to as astigmatism. This kind of abnormal shape makes it challenging for other kinds of contacts to keep in position in your eye. Toric contact lenses tend to be weighted along the bottom to make up for an unusual cornea shape.

Exactly like bifocal glasses, multifocal contacts offer a two-paned look at the world. Based on your needs, one part of the lens could correct for long distance eye-sight whilst the other part corrects for near vision. The two toric and multifocal contacts can be purchased in gentle and rigid gas permeable materials.

Major Labels

The award for the best of all contacts manufacturers goes to the corporation which invented the very first soft disposable contacts: Johnson & Johnson Vision Care. These days, Johnson & Johnson contact brands are usually marketed as Acuvue, which is currently the number 1 brand name around the world. Besides soft contact lenses, the Acuvue manufacturer supplies a huge number of lens types, including multifocal, toric, everyday wear along with extended use.

Bausch & Lomb is yet another well-known contacts manufacturer. Their contacts show up within the Soflens, Purevision and also Optima brand names. Bausch & Lomb specializes in soft contacts as well as firm gas permeable contacts. Whilst not as prominent as Johnson & Johnson brands, Bausch & Lomb remains one of the most well-respected healthcare brand names on the market.

As far as rigid gas permeable experts go, the Boston firm retains this specific nook of the industry. Created specifically for those who have sensitive sight, astigmatism as well as dry eye difficulties, Boston contacts work effectively for all those who've got troubles putting on soft contacts and also eyeglasses. Boston brands consist of Envision as well as Equalens.

Colour Enhancements

In the event you're trying to find a completely new appearance, the actual CIBA Vision company holds the standing as the world's primary tinted contact lens provider. CIBA Vision markets their particular color-enhanced contact lenses under the SoftColors and Illusions brand names. Their contact lenses use a patented three-in-one colour pattern that permits wearers to change or boost the current eye color. With a wide range of colors offered, their color-enhanced contacts are available in soft as well as multifocal contact lens sorts.

Moisture Enhancements

As many people have the dried up eyes symptoms due to staring at a computer display screen for long hours on end, contact brands from Proclear Compatibles appeal especially to dry-eye sufferers. Proclear Compatibles lenses materials make use of a superior technology that prevents dirt as well as deposit build-up along lens surface areas. The contact lens materials are additionally made to maintain moisture so consumers can enjoy full days of comfort in their own lenses.

Correcting For Astigmatism

Lastly, anybody clinically determined to have the irregular-shaped cornea may want to consider looking at contact lenses produced by CooperVision. CooperVision is the top manufacturer of toric contacts and also the 4th largest maker of contact lenses in the world.

As astigmatism conditions require a custom-fit lens, CooperVision takes pride in supplying quality specialty lens for the most difficult to please eye types. CooperVision brand names consist of Encore, Expressions, Preference and HydraSoft.

Wrap Up

Although many companies concentrate on a number of varieties of contacts, the things that work for one person's eye might not work effectively for another individual. This is especially the case for folks who have got very distinct prescription needs. All this is to say, if one pair of contacts doesn't feel very appropriate, additional contact brands might work. Your eye doctor could work together with you to discover that ideal fit.

Different Types Of Contact Lenses

By Dr Lori S. Nishida-Eugenio, Od

A few years ago, I went to get fitted for contact lenses. It was my first time trying to wear lenses. I was given a lot of options. The optometrist said I could go with hard lenses or soft. I could change my eye color to blue or purple. I could get daily wear or have the same pair for a year.

With so many choices, purchasing lenses can be extremely confusing. This post should aid you in deciphering some of the terms frequently used when talking about contact lenses.

The original contact was Gas permeable contact lenses, otherwise known as hard contacts. These provide many benefits to the hard to fit contact lens wearer. They are better able to correct vision problems and give you the sharpest vision possible. They are also long lasting and do not tear like soft lenses can.

Hard lenses are made in such a way that allows a lot more air to get to the cornea. This, your eye doctor will tell you, has an essential job in stopping eye problems and eye infections. So if you happen to be someone that gets a lot of eye infections, you might want to consider these lenses.

Gas Permeable lenses may also save you money in the long run. Since they hold their shape and do not tear easily, a Gas Permeable lens is likely to hold up and be worn for many years. There durability is another reason that they are called hard lenses.

On the negative side of things, lots of people discover Gas Permeable lenses are extremely uncomfortable. There is obviously a reason that they are called "hard lenses"! It could take the wearer a long time to get used to the feeling of these contacts. Once you do get used to them, people find that if they do not put on the lens everyday then their eyes, which took as long to change, come to be unadjusted and start hurting again!

If you don't wear you contacts all day, for most of the day then you probably won't be able to wear gas permeable lenses. They really require commitment or your eyes will hurt and you will suffer.

Hard lenses last longer than soft lenses but keep in mind that the replacement cost of gas permeable lenses is much higher. Since you should not need to replace them that much, you it shouldn't really matter. The costs, as mentioned, should even out.

One of the reasons these lenses are recommended for people whose eye sight is constantly changing is because it has been proven that hard lenses can slow down the rate at which your eye sight changes. Though children do not often wear contacts, this could be a reason to consider putting them in contacts.

There is also the world of disposable contact lenses. In short, you can choose to wear a new pair of lenses every single day! You can change your lenses once a week or monthly. You can even sleep with them in your eyes at night.

Also, with daily lenses, you will not have to buy solution or contact lens cases.

Overall, like with anything you are going to buy, there are a lot of factors to take into consideration. Speak to your optometrist to figure out just what his point of view is.
