- Are contact lenses comfortable?
Correctly fitted contact lenses should feel comfortable, and most modern soft lenses are made from breathable, moisture-rich materials.

- Can contact lenses scratch your eye?
Contact lens related problems can occur, however this is very unlikely. Most common eye-health issues are related to poorly fitting lenses or not following your opticians care and wear schedule.

- Is my contact lens prescription different to the prescription for my glasses?
Yes. A prescription for contact lenses requires different information than a glasses prescription.

- How do I get a contact lens prescription?
Start by scheduling a contact lens appointment with an optician. Your first contact lens fitting will take a little longer than a regular eye examination, so make sure you specify that you are interested in contact lenses.

You can find an optician near you that fits and sells ACUVUE® Brand Contact Lenses here.
- What is base curve?
The base curve is the back curvature of a contact lens. It’s used to match the curvature of the lens to your eye to provide the most comfortable fit for you.

WEAR & CARE
- Is it difficult to take care of contact lenses?
Not difficult, just a matter of practice! This will also depend on the type of contact lens; daily disposable lenses are simply discarded at the end of the day while reusable lenses are cleaned and put into disinfecting solution overnight.

- What is the difference between daily disposable and reusable contact lenses?
The main difference is how often you replace the lenses for a new pair.
Daily disposable contact lenses are used for one day and then thrown away, so they don’t involve the use of contact lens solutions. You will start with a new pair every time you put on your contact lenses.
Reusable contact lenses for daily wear require cleaning after you take them out, and are normally left to soak overnight in contact lens disinfecting solution The lenses are replaced with a new pair according to your optician’s instructions, usually every two weeks or every month.
- What is the difference between toric contact lenses and astigmatism?
Toric is the name for the design of contact lenses needed to correct astigmatism. A toric lens has a different focusing power horizontally than it does vertically, enabling it to correct astigmatism. Astigmatism is a common condition that can result in blurred or distorted vision at all distances. It can affect people at any age and often people with astigmatism are short-sighted or long-sighted too. Astigmatism occurs when the surface of the eye (cornea) or the lens behind it is not a round shape, but oval like a rugby ball. This distorts the light entering the eye which does not focus correctly on the retina, and as a result the image is blurred.
- What is the different between bifocal and multifocal contact lenses?
In general, bifocal contact lenses are designed with only two zones of vision - near and far. Multifocal contact lenses are designed with more than two zones of vision, helping you see more seamlessly near, far and in-between.
- What is hydrogel?
Hydrogel is the soft, water-holding material used to make contact lenses.
- What is a silicone hydrogel?
Silicone hydrogel is a newer generation soft contact lens material that is highly breathable.
- What does Dk and Dk/t mean?
Dk, or oxygen permeability, refers to the degree that oxygen can flow through a contact lens material.
Dk/t or oxygen transmissibility, determines how much oxygen gets through a lens of a specific thickness.
Dk or Dk/t are not direct indicators behind lens comfort as several other factors can play a part. Your optician is the best person to advise you about this.

- Are contact lenses more expensive than glasses?
