Thinking of Getting Contact Lenses to Correct Your Vision? Here’s What You Need to Know

Jul 05, 2021

Do you want to switch from eyeglasses to contact lenses? Contact lenses are a fantastic choice if you need to correct your vision and you don’t like the idea of wearing glasses or undergoing LASIK surgery.

Millions of people are using contact lenses around the world, and you might not even notice it. These incognito helpers have evolved ever since they were invented in the late 19th century to the variety that we have today. Our optometrist in Toronto has colored contacts, bifocal contacts, and many more for all our patients who desire to use eye contacts.

Without further ado, let’s see what eye contacts are about.

Contact Lenses 101

Contact lenses, commonly referred to as contacts, are thin plastic lenses that people place directly on the eyes’ surface to correct vision. The contact lenses float on your tear film that envelops the cornea.

However, there are also colored contact lenses that you can get from our optometrist near you that are used entirely for cosmetic purposes. But, some people go for prescription colored contacts, which correct vision and improve their appearance.

Contact lenses operate under the same principle as eyeglasses because they correct vision problems that arise due to refractive errors. Refractive errors mean that your eyes cannot focus or bend light as they should, resulting in blurred vision.

This means that contact lenses can be used to improve your vision if you have any of the following refractive errors:

  • Presbyopia
  • Astigmatism (distorted vision)
  • Myopia (nearsightedness)
  • Hyperopia (farsightedness)

Types of Contact Lenses

As mentioned earlier, contact lenses have evolved throughout the years. Now, they are made from different types of plastic. The most common types of contacts available at Yorkdale Eye Care are:

Hard Contact Lenses

Hard contacts are fashioned from transparent rigid plastic combined with other materials. The most common type of hard contacts is the rigid gas permeable lens (RGP). When you wear them, they hold their shape firmly and still allow oxygen to pass through the lens.

The RGP lens provides sharper vision than soft lenses since they tend to shape the cornea hence change the way your eye bends light. This means that people with astigmatism and keratoconus will benefit a lot from RGP lenses. Also, if you tend to get protein deposits on your contacts or have allergies, RGP lenses are the way to go.

Soft Contact Lenses

Most people gravitate towards soft contact lenses because they are comfortable, and there are many options. Here are some of the options:

  • Daily Wear Contacts

You wear these contacts when you wake up, and you remove them when you go to sleep. Most of them are disposable, meaning you wear a new pair every day. If you wear contacts more often, our optometrist in Toronto recommends that you choose a contact that lasts a bit longer and needs to be replaced once every week, or two weeks, or a month.

  • Extended Wear Contacts

You have the option of wearing these contacts while you sleep, but they need to be cleaned at least once each week. However, our optometrist near you doesn’t recommend these contacts since they can increase the chance of getting an eye infection.

  • Toric Contacts

These contacts are designed to help correct astigmatisms and must be specially fitted for each person based on the optometrists measurements. RGP lenses are still a very good option for astigmatisms as well however.

Worthy Mentions

Also, there are other types of lenses that have different features, such as:

  • Multifocal Contact Lenses

These include bifocal lenses that have different levels of prescription for far and near vision. They are used to correct presbyopia, farsightedness, and nearsightedness.

  • Cosmetic Contact Lenses

These include colored contacts and the special-effect contacts that are used during Halloween or just for fun.

  • Bandage Lenses

These are designed to cover the surface of your cornea for comfort after a surgery or injury.

Which Contact Lens Is Appropriate for You?

First, we need to ensure that your contact lens prescriptions is correct for your needs and the lens needs to fit your eye. You may need to consider your wish list, including the color or wearing time.

Remember, though, that all contact lenses are medical devices. It doesn’t matter if they are for cosmetic purposes. This is because complications such as inflammation and infections can arise. So, make sure you visit Yorkdale Eye Care for a contact lens fitting so that our optometrist in Toronto can find the contact lens that is the best fit for your needs.
