People choose to wear contact lenses for many reasons. Aesthetics and cosmetics are the main motivating factors for those who want to avoid wearing glasses or to change the appearance of their eyes. Others wear contact lenses for functional or optical reasons. When compared with spectacles, contact lenses typically provide better peripheral vision. This can make them preferable for sports and other outdoor activities. Contact lens wearers can also wear sunglasses, goggles, or other eyewear of their choice without having to fit them with prescription lenses or worry about compatibility with glasses.

Daily disposable contact lenses are single-use lenses that are removed and discarded at the end of each day. A new pair of lenses is applied to the eyes the next morning, and therefore require no care. Daily disposal contact lenses are gaining in popularity among practitioners and consumers for their health and convenience benefits

These lenses are available in Spherical, Toric and Multifocal form, although in toric and multifocal form, only in some prescriptions.

The average age of contact lens wearers globally is 31 years old, and two-thirds of wearers are female.

Daily disposable contact lenses are ideal for people who are on the go, and those individuals who want to wear lenses occasionally, as with traveling, or perhaps only on weekends. They are ideal for persons playing sport where it is difficult to play a particular sport with corrective spectacles, and then the lenses are worn during this time only.

These lenses are also best suited to those in environments where access to ablution facilities is lacking. Children are also best suited to daily disposables, as there is reduced risk of infections due to wearing regimen compliance and the potential of lens contamination where hygiene is lacking.

Corrective multifocal daily disposable contact lenses are designed to improve vision for both near and far. It must however be stressed that vision at near and far is not as clear as it might be with spectacles, but this no way detracts from the usefulness of the lenses, which offer you the convenience of being able to see both near and far with the same pair of lenses, although a compromise on absolute crystal clear vision is unavoidable, and must be expected.

Monovision is the use of single-vision daily disposables, which are spherical, (one focal point per lens) to focus an eye (typically the dominant one) for distance vision and the other for near work. The brain then learns to use this setup to see clearly at all distances.

While asleep, oxygen is supplied from the blood vessels in the back of the eyelid. A lens in the eye while asleep, can hinder the passage of oxygen to the cornea causing oxygen starvation to the cornea which can result in serious complications, such as corneal ulcer that, if left untreated, can permanently decrease vision

Wearing daily disposable lenses overnight also has an increased incidence of corneal neovascularization (small vessels growing int the clear cornea). This condition, once it sets in, cannot be reversed and will eventually spoil vision acuity through diminishing corneal transparency

Before touching the contact lens or the eye, it is important to wash hands thoroughly with soap and rinse well. Drying of hands using towels or tissues before handling contact lenses can transfer lint (fluff) to the hands and, subsequently, to the lenses, causing irritation upon insertion. Towels, unless freshly laundered on high temperature wash, are frequently contaminated with large quantities of bacteria and, as such, should be avoided when handling lenses.

Dust, lint and other debris may collect on the outside of contact lenses. Again, hand contact with this material, before handling contact lenses, may transfer it to the lenses themselves. Rinsing the case under a source of clean running water, before opening it, can help alleviate this problem. Next the lens should be removed from the foil tab, and inspected for defects (e.g. splits, folds, lint).

The technique for removing or inserting a contact lens varies. There are many subtle variations to insertion and removal techniques. Because of differences in anatomy, manual dexterity, and visual limitations, every person must find the technique that works best for them. In all cases, the insertion and removal of lenses requires some training and practice on part of the user. If in doubt, please contact your eye care practitioner.

Daily disposables are discarded after a single use and thus require no cleaning.

Researchers have linked ultraviolet (UV) light to the formation of cataracts. Exposure to excessive UV light also may result in a condition called photokeratitis, that's why some contact lenses now contain a UV-blocking agent. You can't tell if a contact lens has a UV blocker just by looking at it. The blocking agent is clear, so as not to disturb vision. The contact lens packaging will specify if the product has a UV blocker, or you can ask your eye care practitioner.

Very important: UV-blocking contacts are not meant to replace sunglasses. A contact lens covers only your cornea, not your entire eye.

However, UV-blocking contact lenses do help protect the portion of the white of your eye that is covered from formation of growths such as pingueculae and pterygia.

Sunglasses with UV protection can cover more of your eye and the parts of your face that surround the eye, depending on the size of the sunglass lens. That's why contacts with UV blockers are designed to complement sunglass use as an added protection.

Contact lenses are generally safe as long as they are used correctly. Complications from contact lens wear affects roughly 5% of wearers yearly. Factors leading to eye damage varies, and improper use of a contact lens may affect the eyelid, the conjunctiva, and, most of all, the whole structure of the cornea. Poor lens care can lead to infections by various microorganisms

Many complications arise when contact lenses are worn not as prescribed (improper wear schedule or lens replacement). Sleeping in lenses not designed or approved for extended wear is a common cause of complications. Many people go too long before replacing their contacts, wearing lenses designed for 1, 14, or 30 days of wear for multiple months or years. While this does save on the cost of lenses, it risks permanent damage to the eye and even loss of sight.

Mishandling of contact lenses can also cause problems. Corneal abrasions can increase the chances of infection. When combined with improper cleaning and disinfection of the lens, a risk of infection further increases. Decreased corneal sensitivity after extended contact lens wear may cause a patient to miss some of the earliest symptoms of such complications.

Safety Tips:

1. DO always rub contact lenses when you clean them, even if using a "no-rub" solution.
2. DO make sure contact lenses and lens storage cases are cleaned and disinfected regularly.
3. DO replace contact lenses regularly, according to your Eye Care Practitioner's directions.
4. DO put your lenses in before applying Eye Makeup.
5. DO always wash hands before handling contact lenses.
6. DO remove lenses before removing Eye Makeup.
7. DO have an annual checkup to ensure your eyes remain healthy and to check lens powers.
8. DON'T place contact lenses in your mouth or use your saliva to wet them.
9. DON'T "top off" old solution in your contact lens case. Instead, discard old solution and replace it with fresh solution.
10. DON’T apply eyeliner between your lashes and your eye.
