Contact lenses, also known as colored contacts, are thin translucent lenses placed directly onto the cornea of the eye. Contacts are popular ocular prosthetics used by more than 150 million individuals worldwide, and they are often worn for corrective vision, to improve vision, or for therapeutic or aesthetic reasons. The contact lens is one of the most comfortable and least invasive forms of corrective eyewear, which makes it a popular choice for patients. In addition, in-home use is simple and inexpensive, while at the same time providing premium quality vision correction.
A wide range of soft contact lenses are available, from those made of extended-wear polycarbonate to those that only need to be worn for two weeks. The two-week soft lenses are the most flexible of all and come in a wide range of colors, such as green, yellow, light brown, or blue. If you wear a lot of fine hair color, you may want to consider wearing brown or blue colored contact lenses, since these are the most visible colors with dark hair.
To begin your search for a new contact lens, you should first schedule an appointment with an optometrist. This expert can help you find the right fit and can also order custom fitted contacts for you if necessary. To maintain the optimal comfort level, it is important that you clean and disinfect your contacts after each use. Although your optometrist can recommend specific contact lenses care products, you should try to use as many of them as possible. Some of these products include eye drops and wipes, which can help to eliminate bacteria and dryness on your eye’s surface.
Some people choose to wear gas permeable lenses. These soft lenses allow some of your natural eye color to show through, so you don’t have to completely change your look. A gas permeable lens usually covers more area of your eye than a traditional contact lens would, giving you a more uniform appearance. However, these types of lenses are not appropriate for astigmatism sufferers or those who have eye allergies.
The final type of contact lens to consider is silicone hydrogel. These lenses are made from a special type of silicone gel. Since they are made from a gel, there is little risk of infections. However, there are some advantages to these lenses. They are not as bulky as the other options, which makes them easier to handle and wear. Also, they do not offer as many benefits as gas permeable lenses, since they tend to be less resistant to infections.
RGP lenses (rigid gas permeable lenses) are often prescribed by ophthalmologists when the patient has problems with astigmatism. Because these lenses have a higher degree of resistance to infections, they can also be prescribed for people who may have eye allergies. In fact, many allergies may be traced back to having a poor fitting contact lens, so having an RGP lens is a good idea. This lens type can also be prescribed to those who are at a greater risk for corneal infections, such as those with cataracts. Because this type of lens is higher in resistance to infections, it is often prescribed to those who may be prone to infections.
