CHOOSING YOUR CONTACT LENSES

You and your eye care practitioner will discuss which type and style of contact lens best suit you. The choice depends primarily on your vision problem, but you'll also need to consider what recreational and work activities you do, how often you want to wear your contacts, and how much time you're willing to devote to their care. After you've chosen between soft and rigid gas-permeable lenses, pick a style that fits your needs.
Type of Lens
Carefully consider the pros and cons of each type of lens. Your eyecare practitioner will help you decide whether soft lenses or rigid gas-permeable lenses are best for you.

	PROS	CONS
Soft Lenses	Initially more comfonable and easier to adapt to than rigid lenses Seldom pop out of the eye or slip off-center, making them a good choice for sports Less likely than rigid lenses to trap particles under the lens Available as disposable lenses	Harder to clean than rigid lenses Vision may not be as sharp as with rigid lenses Wear out faster than rigid lenses Can't be used with some eye medications Can't be used to treat some forms of astigmatism May rip or tear
Rigid Gas-Permeable (GRP) Lenses	More durable than soft lenses Easier to clean than soft lenses Vision may be sharper than with soft lenses Less expensive than soft lenses Can be used with most eye medications	Harder to adapt to and initially less comfortable than soft lenses More likely to pop out of the eye or slip off-center than soft lenses More likely to trap particles under the lens than soft lenses May chip or scratch

Deciding on a Style
Not only are there different types of lenses, but the lenses are available in different styles. Certain styles correct specific vision problems, allow you to wear your lenses overnight, or let you change the color of your eyes. Only soft lenses are available in every style. The chart below tells you the different ways you can get each type of lens.

	SOFT	RGP
Daily-Wear Lenses Most common type of lens Taken out at night to be cleaned and disinfected Cannot be worn safely during sleep
Extended-Wear Lenses Can be worn continuously for up to a week or used as daily-wear lenses May cause more frequent problems than daily-wear lenses when worn for extended periods
Disposable Lenses Extended-wear-worn for up to a week, then replaced by a new pair Daily-wear-regularly thrown out and replaced by a new pair
Bifocal Lenses Like bifocal glasses, improve both far and near vision May take longer to see clearly with these lenses than with traditional contact lenses
Torlc Lenses Specially curved lenses designed to correct astigmatism, a condition in which an irregularly shaped cornea distorts images
Cosmetically Tinted Lenses Change or enhance eye color
Lightly Tinted Lenses Don't affect eye color, but are easier to see when they're out of the eye
