Common questions

Are rigid contacts better?

Are rigid contacts better?

Rigid gas permeable contact lenses are more durable than soft contact lenses. They’re also more breathable, allowing more oxygen to the cornea. These contact lenses must be removed for cleaning and disinfection at night, but some can be worn for a week or even 30 days.

What is a truncated contact lens?

Truncation: When a lens is truncated, a portion of it is sectioned off. It is usually 0.50 to 1.5 mm on the lower edge of the lens. The amount sectioned off will depend on the size of the lens; larger lenses require greater amounts than smaller lenses.

What are the strongest contact lenses?

The highest level of corrective power for monthly soft contact lenses is about -12 Dioptres (bear in mind that the average prescription for short sighted people is -2.00 Dioptres), and is available from both Purevision 2HD and Biofinity.

Are soft contact lenses safe?

The overall risk is still small (3.5 per 10,000 people wearing daily soft lenses), but keratitis is painful, can make your eyes weep and causes blindness.

What is the difference between soft and hard contacts?

Hard contacts, or rigid gas permeable contacts, are not as flexible as soft lenses, but they are more durable. These lenses also let oxygen flow through to your eyes, which helps increase comfort. Unlike soft lenses, hard lenses do not change shape when you put them on.

What is the difference between toric and astigmatism?

Toric contact lenses can rectify astigmatism. The main difference between these and regular lenses is the design. Regular lenses have just one power, but toric lenses have two: one for distance vision and one for astigmatism.

How do you tell contacts apart?

If you are wearing the same type of contact lenses in both eyes, there is no way to tell as they look exactly the same. If you wear, for example, a soft contact lens in one eye and a rigid gas permeable (hard lens) on the other, then obviously you can tell by the way they feel in your fingers.

Are stronger contacts thicker?

However, it’s important to know that soft contact lenses with high powers have thicker edges compared to low-power ones. For this reason, they are more likely to be discernible in the eye and less comfortable to wear.

Do soft contacts change eye shape?

Along with increasing your chances of infection and reducing the thickness of your cornea, contacts also, over time, change the shape of the eye. This effect isn’t anything you really need to worry about as it likely won’t affect your vision.

Is it bad to wear contacts everyday?

Most contact lenses should not be worn overnight, as it could increase the risk of eye infection. Contacts meant for daily or one-time use can generally be worn up to 14 to 16 hours with no problem, but your doctor may recommend a contact-free hour or two before bedtime in order to rest your eyes.
