Spherical

What are Spherical lenses?

A Spherical contact lens is a type of contact lens that has the same power throughout the whole contact lens. These lenses can be used to correct myopia (short sightedness), hyperopia (long sightedness), and presbyopia (age related farsightedness).

Who needs to wear a Spherical contact lens?

People who are suited to these types of contact lenses are those who need vision correction for either myopia or hyperopia. Spherical contacts can come in a range of daily disposable contact lenses, extended wear lenses, and coloured contact lenses for your particular use. Ensure that you follow the directions for your different types of contact lenses and always refer to your optometrist if you are having difficulties.

Are Spherical lenses and Toric lenses different?

Spherical and Toric contacts are two types of contact lenses that differ in their curvature and focal power on their surface. While both Toric lenses and Spherical lenses are both prescription contacts, they are suited to different people.

Toric lenses are better suited to those with astigmatism where the shape of the lens or cornea of the eye is shaped like a donut. Toric lenses address both eye astigmatisms and issues around distance vision.

For Spherical contact lens prescriptions, the wearer will suffer from either nearsightedness or farsightedness. These two types of contact lenses also differ from multifocal contact lenses where more than one prescription can be accommodated.

Using the incorrect type of contact lenses can result in blurry vision problems and affect your eyes health.

Can you wear Spherical lenses overnight?

No. When contact lenses are worn overnight can deprive your eye of oxygen and irritate your eyes, resulting in sore eyes and a higher risk of infection. If you want to use extended wear contacts lenses, ensure that you purchase multi-use lenses and clean them as directed. This same rule applies to those who use multifocal lenses, cosmetic contact lenses, soft contact lenses, or RGP lenses.

Can you use Spherical contacts for astigmatism?

No. This shape of contact lenses is not suited to those who have an astigmatism. If your astigmatism is only slight your optometrist may recommend Spherical contacts, but a Toric contact lens is better suited and will cause less damage to your eye’s health.
