Why do people wear contact lenses?

There are people that wear contact lenses, rather than glasses, for esthetical reasons. They like themselves better with contact lenses than with glasses. one more reason that determines people to wear contact lenses is that the cosmetic one. there's an excellent sort of decorative contact lenses that will change the eye’s appearance. And there are those that appreciate their practical side. they can't play certain sports with glasses; they use devices that are incompatible with glasses etc. there's that category of individuals who are forced to wear contact lenses for therapeutic reasons. In their case, the contact isn't an option. The contact is often a bandage within the healing process of various diseases or injuries of the cornea and it's a luxury that heals. there's also a mixture between the 2 reasons - color lenses with correction power which actually please tons of persons.

The first contact lenses ever made were developed out of glass. Then, new types appeared, because the ones made from Plexiglas and therefore the rigid gas permeable ones, but, nowadays, the soft contact is that the most appreciated. Modern materials include silicon hydrogel or other plastic polymers like etalficon A. galyficon A, senofilcon A (used within the fabrication of Acuvue contact lenses). Rigid gas permeable contact lenses are recommended to the persons with dry eyes as these lenses contain no water that would evaporate during the wearing.

If you opt to wear contact lenses, you initially need to attend an ophthalmologist, regardless of what your reason could also be. The doctor is going to be the one to make a decision on which sort of contact lenses suit your eyes best. various factors are going to be considered for the prescription of a particular contact lens: the fabric (the silicone hydrogel is one among the most recent discoveries within the field), the wearing time (daily wear, extended wear or continuous wear), the form (spherical, toric or multifocal) and lots of more. Depending on the fabric, the contact is often either rigid or soft. The rigid one is often gas-tight or gas-permeable, but the soft one is usually gas-permeable. There also can be an extra classification made on the moisture content, on the quantity of water within the contact.

The wearing time

Daily contact is safer because the risk of infection is less than at the future contact. this sort doesn't require cleaning, being single-use only. it's sterile. And it even keeps you faraway from pocket money on cleaning or storage solutions. On the opposite hand, the extended wear sort of contact lenses allows people to simply wear contacts for an extended period while allowing oxygenation (they usually have a high oxygen permeability rate). Some people prefer them as their convenience is clear, but the danger of infection is above at the daily sort of contact lenses thanks to the bacterial stagnation, dust accumulation than on.

One of the foremost popular contact lenses brands within the world is Acuvue, produced by Johnson & Johnson’s subsidiary Vistakon Company. they supply both vision and esthetical contact lenses. They design disposable lenses, making types that are to get replaced every fortnight (Acuvue, Acuvue 2, Acuvue 2 Colors, Acuvue Advanced, and Acuvue Oasys) or less (1-Day Acuvue). They’ve also started making extended wear lenses.

Where to shop for them from

Contact lens quality is extremely important. Low-quality contact lenses can damage the attention, causing irritations or hurting the eyelid or the cornea.
