Types of Contact Lenses and Their Compatible Uses

Contact lens is a cosmetic, corrective, or therapeutic lens usually placed on the cornea of the eye. Basically Contact lenses are substitute of glasses, but these are lightweight and virtually invisible. But now, many commercial lenses are tinctured faint blue to make them more visible when immersed in cleaning and storage solutions. Some cosmetic lenses are mainly colored to alter the appearance of eye and some lenses have a thin surface treatment with UV coating which helps to reduce UV damage to eye’s natural lens.

Contact lenses are mainly used for two common purposes, to treat certain eye diseases or to change the apparent color of your eyes. Today, there are many options available for contact lenses. One can choose disposable lenses which can be changed over a night, or one can wear lenses for entire month too. If you want baby blue color in your eyes, then opt domestic contact lenses and if you have certain vision problem then this invisible tool is best for you. You can choose any contact lens according to your need or like. First acknowledge yourself with types of contact lenses, only then you can choose a best suited pair of lens.

Contact lenses can be divided into two main categories: Soft Contact lenses and Rigid Gas permeable.

Soft Contact lenses: Soft contact lenses are mainly of three types – daily disposables, extended wear disposables, and colored contact lenses.

Daily Disposables and Silicone Extended Wear Disposables: These contact lenses are made up of soft polymer-plastic material combined with a percentage of water. Due to water, oxygen can pass through the contact lens material which increases comfort. Some soft lenses provide UV protection also. There are also other soft lenses too, which are worn on a yearly basis and are not disposable. The most recent types of soft contact lenses in the market include Daily Disposables and Silicone Extended Wear Disposables. Silicone Extended Wear Disposables are made from a new silicone hydro-gel material that can be worn for up to 30 nights and days.

Colored Contact Lenses: Colored Contact Lenses are mainly meant to change the appearance of eyes. But they have vision corrective capability also. These are basically of four kinds – visibility tint, enhancement tint, color tint and light filtering tint. These four types of colored lenses serve the different needs of people as per the color visibility. Just remember, colored contact lenses are also a medical device and used for corrective purpose also. So, never give your colored contact lenses to anyone to wear.

Besides above mentioned benefits, soft lenses have some disadvantages too. Soft contact lenses easily absorb pollutants, soap or lotion. They are fragile too, which can irritate your eyes.

Rigid Gas permeable lenses:
Rigid Gas permeable lenses are more durable and easy to take care. These are made up with silicone polymers and allow oxygen to circulate to the cornea of the eye. They take more to adjust in comparison to soft contact lenses. Both soft contact lenses and rigid gas permeable have extended wear option, but should be worn as per your doctor’s prescription. Rigid gas permeable lenses are of two types.

Bifocal Contact lenses:
Bifocal contact lenses are mainly designed to give good vision to people who have presbyopia. These bifocal and mono-vision lenses come in both soft and rigid contact lenses.

Toric Contact Lenses:
Similar to Bifocal contact lenses, these lenses are also meant for vision problem like astigmatism. These are also come in both soft and rigid contact lenses. Toric lenses are used for two purposes, one for the astigmatism and another for nearsightedness or farsightedness.

After knowing all types of contact lenses now you are able to buy a perfect pair for yourself. There are various online stores, where you can get more details about best selling contact lenses. But it is advisable that whatever you buy for your eyes, you must consult your doctor first and buy a product from a known brand likeFreshlook and Acuvue. Take advantage of online deals to order products from 2000+ online stores at discounted prices.

A functional explanation of contact lenses

The whole process of vision correction by contact lenses is complex. While most people know contact lenses can be used to correct common vision problems, very few have detailed knowledge of how they actually work. In fact, before functioning vision correction, contact lenses must be able to sit stably on the eye.

 

It is commonly known that there are mainly two types of contacts, namely soft contacts and RGP ones. A soft lens folds gently over the rounded cornea because it is made of flexible materials. Slightly different, a hard lens does not sit as close to the cornea as a soft lens. Successfully seated over the cornea, contact lenses also require a wearer to properly blink the eye in order to adjust the lenses into a right place. In addition, natural tears and blinking also protect contact lenses against dust and particles. Properly fitted lenses will sit comfortably on the cornea all day long.

 

Different types of contact lenses have different functions. Contacts for nearsightedness and farsightedness only compromise vision problems, rather than correct them or improve eyesight. In detail, a contact lens for myopic is thinner in the middle and thicker on the outer edges. In the contrary, a farsighted individual needs to wear contact lenses that are thicker in the middle and thinner on the outer edges. This difference in shape is reasonable, because myopia and hyperopia are associated with different eye shapes.

 

When it comes to contact lenses for astigmatism, vision improvement is possible. Specially designed toric contact lenses have two prescriptions that align perfectly each time. A toric lens is a little heavier at the “bottom”. Over time, toric contact lenses can gradually correct the abnormal shape of the cornea. In this way, true vision correction can be achieved.

 

Any type of contact lenses should be based on a prior evaluation of the patient’s eyes by an optometrist or ophthalmologist. Corrective contact lenses must offer precise correction power, which is determined by a lens prescription from the doctor.

Free trial contact lenses from many brands

Some people may be surprised that they may get free contact lenses. It is possible because there are so many contact lens manufacturers so that the competition is quite fierce. Contact lenses are the preferable choice for some people that they are not ready for laser eye surgery. And contact lenses offer a more natural appearance.

 

In the United States, contact lenses require a valid prescription from an authentic eye doctor. Customers can go to any optical store or eye care practitioner to have an eye exam, after which a prescription is available. A prescription for contacts is quite different from a prescription for eyeglasses. These two kinds of prescriptions have different items, which is quite understandable that eyeglasses and contact lenses fit the eyes in different ways.

 

Contact lens wearers should also know some pros and cons about lens wearing. Taking good care of contact lenses is very necessary, in order to prevent any eye infection or inflammation. Lens insertion and removal need some skills. For those with special eye conditions such as dry eye, re-wetting drops are needed during the day.

 

Toric contact lenses are specially designed for people with astigmatism. These lenses are harder to fit and adapt to. Sometimes several sets of free trial lenses are needed. With these trial lenses the doctor can finally adjust them properly.

 

Currently, many contact lens manufacturers offer free trial contacts, such as Acuvue, Durasoft, Air Optix, Focus Dalies, Purevision, Cooper Vision, O2 Optix, Johnson & Johnson and Bausch & Lomb and so forth. Customers should not wear these free contacts for a long time. After at most 30 days, they should be discarded. But free contact lenses from several brands can usually support a customer for a long time. Most manufacturers require customers to record something about their trial products. These elements include whether the contacts are comfortable, easy to insert and remove, dry eye problems and so on.

This way enables brands that provide good quality to attract more and more customers. Acuvue is a good example. These lenses work better in several ways.

 

Contact lenses fitting over the cornea must be moist. In fact, a normal pair of contact lenses would float over a layer of tear. In addition, lenses should attract moisture by blending with the natural tears produced by the eyes. Only in this way can contacts work in a normal way to correct vision defects. Acuvue lenses do a pretty good job in this sense. An Acuvue lens is actually 47% water, which is the major component. This design makes Acuvue lenses extremely comfortable and significantly reduces the rate of suffering dry eye.

Toric contact lenses correcting astigmatism

Before the invention of toric contact lenses, people inflicted with astigmatism could only resort to eyeglasses for vision correction. Those days could be an unpleasant memory for those who dislike eyeglasses. This limitation is simply because of an irregular shaped lens or cornea in an astigmatic patient. The aspheric lens shape of astigmatism requires special lens design and fitting. Only several advancements in contact lens technology have made toric lenses available for astigmatic patients.

 

A toric contact lens is specially designed to fit an irregular corneal shape. The aspheric lens in an astigmatic individual requires a toric lens with precise curvatures. Any slight variation is not permitted, otherwise clear vision is impossible. Unlike a spherical contact lens, a toric lens has two different powers. One of them corrects astigmatism and the other is for nearsightedness or farsightedness.

 

Although toric lenses have no significant difference in looking from spherical lenses, they actually have more complex design due to their additional power. Currently, toric lenses have incorporated most features, materials, as well as other lens technological development. However, these benefits were beyond toric lenses in early stages.

 

This is an inevitable development process for most late comers in the lens industry. Initial toric lenses were usually dull in materials and styles, but there were many astigmatic individuals waiting in line. This situation was quite similar when colored contact lenses were first introduced to the public. They became popular quite soon due to the particular benefits.

 

Thanks to progression in lens technology, toric contact lenses are available in a wide variety now. Astigmatic people can always get the same options as those individuals wearing spherical contact lenses. Except for a different shape or curvature, aspheric lenses hardly have differences from spherical lenses in lens materials, styles and so on. Soft, rigid gas permeable and silicone hydrogel types can all be found in toric lenses. Furthermore, toric contact lenses are available in disposable, frequent replacement, colored, bifocal and even multifocal types.

Ready-to-Wear Bifocal Contact Lenses

Eyeglasses with thick lenses and a line across them were the only option for people with both nearsightedness and farsightedness. Eyeglass frames were heavy and not only that they were to say the least unattractive. Bifocal Contact lenses were difficult to get used to wearing. Going down stairs especially, you need to look either up or down. While getting adjusted to wearing bifocals some people get dizzy.

People had only one choice if they wore bifocals, eyeglasses. When contacts hit the market bifocals still had to be in eyeglasses. That was then and this is now. Contacts offer as many choices if not more than the choices available for eyeglass wearers. Many people are joyous because bifocals now come in contact lenses. Contact bifocals are available in rigid, soft, and gas permeable materials.

What people need to use bifocal lenses? Those who when focusing on near objects, have trouble. What they have is called Presbyopia. It is unusual for this to develop before the age of 40. Bifocals glasses are similar to Alternating Design because half the lens has distance power and the other half has powers for near objects.

Blended prescriptions for both near and distant vision are Simultaneous Design; they fill in the area of the pupil. Whether you are looking near or far your eye will adjust and learn to interpret the circle power choice. Concentric Design lenses are the radials of contact lenses. The inner lens works on the nearness vision while the outer part works on distant vision correction or vice versa.

Translating Design- these are also very similar to bifocal eyeglasses, the distance correction is above the near correction. The lenses are divided by a line. The lens has a flat bottom so that when you blink it won’t move around in your eye. The center of the Asferic Design lenses is where both the near and distant vision is located.

The center of the lens is where the near vision correction is and it’s surrounded by distant vision correction. In some situations they can be reversed. You can decide this with your doctor. You wear one power lens in one eye and the other in the other eye with Mono-vision Design lenses.

The distant vision is placed in the dominant eye usually. Here again your doctor’s exam will be able to determine this. Simultaneous vision contacts are also available. Focusing on both near and far objects at the same time is possible with these lenses.

Concentric rings form the near and distant correction. Light from both near and far objects can be focused on at the same time since the near and far parts of the lens are in sight all the time.

Simultaneous vision contact lenses have a problem. When the eye is looking through the lens some of the light from the distant objects will enter the distant part and vice versa. The eye, at the same time takes in out of focus and focus.

The brain has to figure out which image is correct. Your doctor must provide you with a subscription for contact lenses not matter if they are bifocal or not. Your eye doctor will do a very thorough exam to decide if you are a candidate for bifocal contacts and what type might be right for you.

Lenses that fit and are comfortable may take time to find, as with any contact lens there is an adjustment. Bifocal lenses may not be for you, at least not in the contact lenses currently available. Don’t give up the search for the right lenses.

Do your research and keep up to date on the types of lenses available to you if you want contacts and need bifocals. By offering a free trial wear period of up to a week, some companies allow you to try their lenses and see if you like them.

Check out discount contact lens stores online and some manufacturers will give you a coupon to put toward the purchase of their lens if you try them. Your decision about bifocal lenses will without a doubt be affected by your budget.

Ask about the experience friends or family have had with contact lenses. You and your doctor can, with this information make a decision but not everyone has the same experience. The option of bifocal contact lenses is now available for people with astigmatism.

Toric contact lenses come in both color and disposable lenses. Some professionals do not like fitting Toric lenses so it is best to check with your eye care professional.
