Contact lens, or just contacts, are tiny thin transparent lenses placed on the cornea of the eye. Contacts are one of the most comfortable and least invasive forms of cosmetic surgery, allowing you to wear corrective lenses and look normal at the same time. Contact lenses have revolutionized vision care, replacing eyeglasses with an almost effortless alternative. Many millions of people around the world wear contact lenses to address vision problems like nearsightedness or farsightedness, among others. Also, contact lenses are now used as prosthetic, ocular devices to correct visual impairment or other vision deficiencies. People wear contact lenses for a variety of reasons, ranging from for therapeutic or cosmetic reasons, to medical purposes.
The vast majority of contact lens wearers choose to wear lenses because of some kind of therapeutic benefit; either because they want to improve their vision, or because of some symptom they are currently facing, like dry eyes or itching and irritation around the eyes. Regardless of why we choose to wear contact lenses, the most popular variety available is hydration contact lens; these lenses allow the fluid in the eye to drain more easily, therefore decreasing the dryness of the eye. Another popular variety is gas permeable lenses, or gas permeable contacts. These lenses allow some of the fluid to drain, but maintain the proper pressure within the eye, which reduces some of the irritation. Finally, another popular variety is the silicone hydrogel lenses; these lenses use silicone as an active material to keep the eye lubricated and therefore reduce some of the irritation caused by dry eyes.
If you wear contact lenses you probably already know that you need to clean your contact lenses regularly. This is especially important if you wear daily contact lenses. However, there are a few situations where regular cleaning of contact lenses is not recommended, and in those cases, contact lens maintenance is a good idea. First, contact lenses that are regularly cleaned may have some residue remaining from the cleaning agent. Any residue left can irritate the eye and cause symptoms such as itching, burning and water drainage around the eye.
Second, contact lenses that are regularly worn may contain bacteria or other microorganism that can irritate the eye and cause symptoms such as redness, blurring of vision and even eye soreness. However, some of the new generation contact lenses include what is called a hybrid contact lens. This type of contact lens includes silicon hydrogel and allows some amount of moisture to be allowed to drain into the eye through the nose. Unfortunately, this type of hybrid contact lenses has also been associated with a significant increase in eye infections.
When it comes to daily care of your contact lenses, the simplest way to ensure optimal comfort and overall health is to simply ensure that the contact lens is replaced every day. Simply taking the time to replace your contact lenses on a daily basis will allow your eyes to be free of irritation and infections. If you do experience any pain, the easiest way to relieve it is to ice your eyes to relieve swelling. In addition, you should remove any contact lens that has come into contact with your face. Contact lens debris that has become lodged in the eye can actually become infected if it is not removed in a timely manner. Finally, it is important that you wash your hands before touching your eyes so as to avoid any dirt or contamination from getting into your eye.
Although it is important that you follow the correct steps when it comes to taking care of your contact lenses, these steps are only going to take you so far. For best results, it is recommended that you seek the advice of an Optometrist or Ophthalmologist when it comes to the maintenance of your contact lenses. These professionals are trained in the proper care of your lenses and are also skilled at identifying any problems that you may be experiencing. In addition, they are also familiar with the products that are available to provide you with improved comfort and overall visual performance while wearing your contact lenses.
