There are two things you should complete before purchasing contact lenses; learn the facts about contact lenses and visit a vision specialist. As an alternative to glasses, consider contact lenses. They were created more than a century ago, initially from glass and then from hard plastic.
These days, soft plastic is used to make contact lenses. They are tiny, thin discs that can be applied directly to the cornea. Contact lenses are typically prescribed by eye doctors or other qualified eye care specialists for visual issues such nearsightedness, farsightedness, and uneven focus. They may also be recommended by eye physicians to treat specific eye ailments and illnesses.
You must first make an appointment with an eye doctor or other qualified eye care practitioner if you want to wear contacts. Since contact lenses are a medical device, an eye care specialist must properly fit them. Even if you don’t wear glasses and only wish to wear contacts to change the color of your eyes, this is still true. The eye doctor can write you a prescription for contact lenses after examining your eyes to see whether it’s safe for you to wear contacts. Nine out of ten people who want to use contacts can, even though not everyone who needs glasses does. Contact lenses, however, might not be a wise choice for those who:
Had recurrent eye infections. Experience frequent severe allergy reactions. Have lubrication issues with your eyes. Are suffering from a specific vision issue or require special lenses, or are exposed to significant levels of dust, dirt, or smoke. There are various kinds of contacts. Usually, soft and hard objects are used. More oxygen can enter the eye’s cornea thanks to gas-permeable lenses. If using rigid gas-permeable contacts causes you discomfort, hybrid contact lenses a specialized option that you may want to consider.
Daily wear and extended wear are the two most common types of soft contact lenses. Water and a thin, flexible material are used to make both lenses. Every day, daily-wear lenses need to be taken out, cleaned, and stored. Extended-wear lenses are made to be worn all night. Extended-wear lenses do come with an increased risk of infection, though. They should be worn for the amount of time that your eye doctor has advised.
With certain eye diseases, hard contact lenses offer a sharper field of vision, and some varieties may last longer. Bifocal versions of most hard contact lens types are available. Hard contact lens wear may require more time to become used to than soft contact lens wear. When you participate in strenuous physical activity or sports, hard contact lenses may slide out of place more easily.
The benefits of daily-wear lenses are also available with extended-wear soft lenses. Up to one week can pass while using these lenses.
Depending on the type of lens, contacts require different care and cleaning. Every lens must be thoroughly cleaned and stored on a regular basis. Users with daily and extended use lenses need to take extra care to adhere to the suggested lens washing, rinsing, disinfecting, enzymatic cleaning, and lens case cleaning routine.
