Learn the Available Eye Contact Lenses and Their Effects 

 There is a variety of contact lenses that you can choose from. However, in order to decide on the best possible option for you, it is important discover the characteristics of specific products.

Soft Contact Lenses for Daily Wear: These types of lenses are usually made of a soft plastic material, known as polymer. These lenses contain a specific percentage of water, which actually allows oxygen to reach the retina. This technology permits the contact lens wearers to benefit from an increased level of comfort while wearing these types of lenses. Furthermore, most soft contact lenses also deliver UV protection. These types of lenses provide two main categories of products, such as daily disposable and silicone extended wear lenses.

Colored Soft Lenses: As you might already know, these types of lenses are not only fun but also practical for different individuals.
This category is divided into four specific sub-categories, including visibility tint, light-filtering tint, color tint, and enhancement tint. The first category does not affect the color of the eyes. These lenses come along with a slight tint, which can only help you to find them quickly if your drop them on the floor. The light-filtering tin lenses are usually for sports fans and athletes. They have the ability to enhance specific colors, such as the color of the tennis ball. The color tint lenses are those that modify the color of the eyes in green, violet, amethyst, and some other wonderful hues. The enhancement tint lens is suitable for enhancing the natural color of your eyes.

Rigid Gas Permeable Lenses: These alternatives are much more rigid than the available soft lenses. Unlike other types of lenses, these products allow more oxygen to reach the cornea. Additionally, if you compare them to the soft lenses, you will observe that they ensure a clearer vision, being also more durable. In order to feel comfortable while using these lenses, you should wear them every single day.

Bifocal Contact Lenses: These types of lenses are prescribed to those individuals who suffer from presbyopia, which is an age-related condition. These lenses are meant to correct close and distant vision at the same time. As you can find numerous bifocal contact lenses, the best thing that you can do is to have a professional evaluation before you buy contact lenses of any kind.

Corneal Reshaping Lenses: These products are used to correct the shape of cornea. The corneal reshaping lenses are beneficial especially for the individuals, who suffer from near-sight conditions.

Toric Contact Lenses: These types of lenses are able to correct the astigmatism-related issues. They come in different materials, being commonly found as rigid or soft contact lenses. These lenses have two different powers, which allow people to correct two problems at once, such as astigmatism and farsightedness or astigmatism and nearsightedness. 

Regardless of the type of contact lens that you intend to purchase, it is always important to respect the directions that relate to contact lenses’ care and hygiene. Therefore, it is essential to know that before touching the contact lenses, you must wash and rinse your hands properly. You should never use cosmetic soaps especially because these products contain lotions, oils, and perfumes, which can cause eye irritations.

Additionally, you have to use special solutions, which can help you to clean and soak the lenses appropriately. The reason for this is that the tap water contains different bacteria, which can cause eye infections. If you have any doubts with regard to purchasing the right contact lenses and solutions for them, the best thing to do is to contact your ophthalmologist. This professional can easily recommend you the best products that will have a positive impact on your eyesight.

Types of Laser Eye Surgery in detail

What are the different types of laser eye surgery and what do they mean?

 The vast majority of people have heard of laser eye surgery but very few people know exactly what it is and how it works. In addition to this, there are a lot of related laser eye surgery terms that can be confusing as they are often explained in a complicated manner. The aim of this article is to explain all the different types of laser eye surgery in simple, jargon free language:

Laser eye surgery: Laser eye surgery is the general name given to any procedure that corrects the vision by means of a laser. The way that laser eye surgery corrects the vision is by changing the shape of the cornea (outer surface of the eye) in such a way that the prescription in your glasses/contact lenses is eliminated. If you are short sighted, the laser needs to flatter the curve of your cornea, whereas if you are long side the opposite applies. The 2 most common types of laser eyes surgery are Lasik and Lasek eye surgery.

Lasik: Lasik is a type of laser eye surgery and is by far the most common procedure currently being carried out. Approximately 90% of all laser eye surgery procedures are performed using the Lasik method. During Lasik eye surgery a thin outer layer (flap) of your cornea is cut and lifted from the surface of your eye. The laser is then applied to the inner layers of the cornea to eliminate the prescription in your glasses or contact lenses. The flap is then returned back to its original place and is left to heal naturally.

Lasek: Lasek,which is also referred to as PRK, accounts for about 10% of all laser eye surgery procedures. It is generally only performed if your surgeon recommends that you have it as a result of your corneas being too thin for Lasik. During this procedure no flap is created as the laser is applied directly to the outer surface of your cornea. The procedure produces just as good results as Lasik but the recovery time is far longer and more painful. Most people require about 1 week off work following Lasek, compared with only 1 – 2 days following Lasik.

Intralase: Intralase is actually a type of Lasik and relates to the way in which the flap is created during the procedure. With standard Lasik the flap is created using a surgical blade (microkeratome), whereas with Intralase the flap is created using a special type of laser. Intralase Lasik is also referred to as bladeless Lasik and is generally considered to be slightly safer with a quicker recovery time.

Wavefront laser eye surgery: Wavefront, which also referred to as custom laser eye surgery can be performed in conjunction with both Lasik and Lasek. Wavefront relates to the way in which the laser is applied to the cornea. During standard laser eye surgery the laser corrects the vision in a generalised fashion, whereas with Wavefront the laser corrects every tiny imperfection of your prescription giving you a higher chance of achieving 20:20 vision.

I hope this helps explain all the different procedures and terminology in a way that is understandable. As laser eye surgery is a rapidly changing field there will always be newer techniques being introduced. The laser eye surgery clinics also confuse things further by giving their own brand name to certain procedures. For example Intralase Lasik with Wavefront may be given the name Ultra Elite laser eye surgery. You just need to ask the clinic what exactly it refers to and with the knowledge acquired from this article you should be able to understand exactly what they are offering.
