Types of Contact Lenses

0

There are different types of contact lenses for different situations. Each of those lens types has various options like fit, comfort level, or brand. This post explains the types of contact lenses to help you determine the best contact lenses for you.

Length of Wear

Disposable contact lenses are designed to be worn for a specific amount of time. Daily disposable lenses are designed to be worn for one day and thrown out at the end of the day. Two-week lenses are designed to be worn for two weeks before they are discarded. Monthly contact lenses are designed to be worn for a month (about four weeks) before they are changed out.

Some contact lenses are designed to last longer than disposable lenses. Conventional lenses are designed to be worn for several months, up to a year. Although they are a high-quality option for vision correction, conventional contact lenses tend to require more care than disposable lenses and are more expensive to replace.

Hard contact lenses are another long-term option. These days, most hard lenses are gas permeable, which means that oxygen can flow through the lenses to reach the eye. Hard contact lenses are more durable than disposable lenses, and they don’t dehydrate like soft lenses. However, hard lenses can be more expensive than disposable lenses, be more likely to scratch, and can sometimes move from the centre of the eye.

Corrections

Contact lenses correct many vision conditions. The best contact lenses for your vision condition can be determined with the help of your vision specialist. Regular visits to your vision specialist ensure that you continue to wear the contact lenses that are best for you.

Spherical contact lenses treat the common vision conditions of myopia (nearsightedness) and hypertrophy (farsightedness). Tonic lenses, in contrast, are cylindrical in shape. They are used to correct astigmatism.

Multi focal lenses have different corrections built into the same lens and are often used to treat presbyopia – a type of nearsightedness caused by ageing. Mono vision contact lenses are sometimes used to treat the same condition. With mono vision lenses, one lens is used for far sight, and one is used for near sight.

Aesthetics

Contact lenses can be worn for aesthetic reasons, either with or without vision correction. The two types of contact lenses with aesthetic tints are an enhancement and opaque. Enhancement tints are a type of see-through tint that creates a subtle change in eye-colour, while opaque tints change your eye colour completely. Theatrical and costume contact lenses are a type of opaque tint.

The best contact lenses for you, from length of wear to vision correction to aesthetic choice, can be determined with the help and input of your vision specialist.
