Contact lenses are useful vision correctors that work like glasses, except they are placed directly into the surface of the eye. Contacts are thin and shaped to fit over your pupil, and they are prescribed to you by an eye doctor to get the correct lense that will properly correct your vision. Lenses are not supposed to be felt, so you can go about your daily life without a disturbance.
Many people are now switching to contact lenses, especially since new designs and types have been created to further comfort and correcting. Your eye doctor will first need to give you an eye exam and measure your eye to get the right fit. Although some use contact lenses for cosmetic uses to change the color and appearance of the eye, the ones most important to be informed about are the ones used for medical purposes.
Types and Uses
There are several different types of contacts that you can use. Some lenses are harder and thicker, while others softer. The thickness and softness of a contact is preferenced based, depending on the client. The types are also separated into categories of how long they can be worn, as some may be daily disposable while others can last up to a year.
There are options in between as well, as some are biannual or monthly. Contact lenses used for an extended amount of time are still removed at night, but you can get special lenses that are able to be slept in. It is also noted that you should not use contacts over the time allotted, or else they can permanently damage your eye.
There are also contacts designed not to dry out so quickly, as dry contacts can cause major irritation to the eye. The variety of contact lenses is made to give the user more comfort, and to help fit them in your daily life. However, there are a few contacts for those with specific problems and needs.
These contacts work in a way to help improve your field on vision. One lense is set to see far away into the distance, while the other is up close. People who suffer with presbyopia are prescribed these type of contacts.
These contacts are also intended for those with presbyopia. The lenses can correct provide two corrections for your vision, which over time move throughout the contact to give corrective refraction for eyes that are aging.
Torric lenses work with gravity and your eyelid to rotate the lense in the right angle, which in turn corrects the warp that occurs in the cornea that causes astigmatism. These lenses are cylindrical.
The lenses are spherical and are generally used to correct and treat presbyopia, myopia, and hyperopia.
Contacts are a good option from those who want to switch from glasses. Glasses may not stay on as well and may be an annoyance on the face, so lenses are useful and you do not notice them even being in your eye.
Although it may be a challenge at first to get over the fear of placing the lense in your eye, overtime you and your eyes will become used to it. Seriously consider switching to or getting contact lenses, and ask us if you have any questions.
