What Contact Lenses Is Right For You?
While reading glasses and bifocals are commonly thought of as the main treatment of presbyopia, it is possible to restore your vision with contact lenses. Contact lenses for treating presbyopia are available in soft lenses as well as rigid gas permeable lenses.
Alternating Bifocal Contact Lenses - Alternating bifocal lenses are similar to traditional bifocal eyeglasses. Since there are two different prescriptions or powers on each lens, your pupil alternates between the two when you look upward or downward.
Simultaneous Bifocal Contact Lenses - Simultaneous bifocal contacts have two powers on each lens; however, the different prescriptions are blended on the lens and the eye determines which power is needed based on the distance being viewed. These lenses feature a design that is similar to progressive bifocal contact lenses.
Monovision Contact Lenses - When monovision contacts are prescribed to treat presbyopia, the dominant eye is fitted with a lens for distance and the non-dominant eye with a lens for seeing near.

It Is Safe To Wear Extended Contact Lens?
Since they do not require daily cleaning or rinsing, extended wear contacts are often desired for the added convenience that they can provide the wearer. These lenses also offer those with vision correction needs a non-surgical alternative to LASIK surgery.
Contact lenses were initially FDA approved for continuous overnight wear for up to two weeks in the 1980s. However, the approval was modified to 7 continuous days after an increase in eye infections amongst those who wore contacts overnight was noticed.
The extended wear lenses that are available today are made from a new material, silicone hydrogel, which allows more oxygen to reach the wearer's eyes when the contacts are worn. When silicone hydrogel lenses are worn approximately 6 to 7 times more oxygen reaches the lens wearer's eyes, which helps to maintain good eye health.

Choosing Your Contact Lens Online
The good thing about contact lenses though is that they're easily available over the Internet if you prefer to shop from the comfort of your own home. It's important though that you consult your eye doctor first and get a prescription particularly when it's your first time to wear contact lenses. Your succeeding purchases may then be undertaken online.
Since there are many online contact lens stores, you need to be discriminate when choosing. Though your priority is getting the cheapest deal on contact lenses, you wouldn't want to sacrifice the loss of privacy or the trouble of not getting your lenses on time. Your first consideration would be to order from contact lens stores that are within your location. For instance, if you're from the US, it would be easier for you to have your contact lenses delivered from within the United States rather than from the UK and vice versa. This will save on shipping costs and time of delivery. You also have to review their privacy policy to ensure the security of your account and payment details.
Usually, ordering in bulk gets you a good deal on savings than when you buy per box. Not only do you get discounts, but you also have more of your contact lenses in store thus you don't have the fear of running out of them at the inopportune time.
