For many people, glasses are an everyday essential.

Contact lenses can be a fantastic addition for correcting your vision and providing freedom when needed.

Your optometrist will choose from a wide range of different types of contact lenses to find the right one to suit your needs.

Understanding the Types of Contact Lenses:

Advancements in contact lens technology has led to the development of different types of lenses available. The most common types are:

Material

Soft lenses:
These are flexible and often the most comfortable lenses, so are the most popular choice. They are thin and light and easy to care for. They come in various wear schedules, from daily disposables to monthly replacements.

Hard lenses – also known as Rigid gas permeable (RGP) lenses:
These durable lenses offer sharper vision, particularly for those with astigmatism. This type of lens is also prescribed for those with a condition called keratoconus.
The lenses do require a longer adjustment period.

Replacement Schedule

Contact lenses were traditionally removed and cleaned overnight, every night, ready for use the next day. But new materials that have been developed has meant that contact lens wearers now have options.

Daily disposables:
The ultimate in convenience – wear them once only! Perfect for those with allergies or a busy lifestyle. These lenses provide less risk of infection due to their limited time period of use.

Two-weekly or monthly lenses:
These lenses are a more cost-effective option, but require proper cleaning and storage solutions.

Extended wear:
Worn day and night and can be slept in for a recommended period.

Vision Correction

Spherical lenses:
These lenses are designed to correct short sightedness (myopia) or far sightedness (hyperopia).

Toric lenses:
Designed for astigmatism, which causes blurred vision at all distances.

Progressive, bifocal and trifocal lenses:
These lenses offer correction for both near and far vision and are particularly suited to those aged around 40 who need glasses for distance viewing, and may beginning to lose their ability to read easily due to age related changes in their eyes.

Ortho-k Contact lenses:
Orthokeratology (ortho-k) gently reshapes the cornea with custom overnight contacts to temporarily modify or eliminate vision errors – usually short sightedness.

These lenses provide clear unaided vision through the day without the risks of refractive surgery.

Contact Lenses or glasses – which are better?

Contact lenses are not better than glasses and glasses are not better than contact lenses, they are simply different vision correction devices.

The advantages for contact lenses are:

Freedom and Flexibility: Enjoy unobstructed vision during sports, exercise, or any activity where glasses can feel cumbersome.

Wider Field of View: Experience a more natural and unrestricted visual field compared to glasses. Your peripheral vision is not impacted by glasses frames.

Glasses are likely a better choice if you have sensitive eyes. Plus the many coloured variations and material compositions used in glasses frames provide an abundance of fashion choices.

Correct fitting

You should see your optometrist to determine the right vision aid for you needs.

Contact lenses fit on the cornea of your eye, which needs oxygen to stay healthy, so it’s really important that when your contact lens is fitted the lens allows the cornea to get the oxygen it needs.

Maintaining Healthy Vision with Regular Eye Exams

Whether you choose glasses, contacts, or both, regular eye check-ups are vital for maintaining healthy vision. Here’s why:

Early Detection: Eye exams can detect signs of eye diseases like glaucoma or macular degeneration in their early stages, allowing for prompt treatment.

Prescription Updates: Your vision can change over time, and regular check-ups ensure your lenses are providing optimal correction.

Eye Health Monitoring: Optometrists can assess your overall eye health, including checking for dry eyes or other conditions.
