Contact lenses are very common medical instruments worn directly onto the cornea of your eye. Like glasses, contact lenses perform this primary function by adding or removing focusing power to the lens and the corneal surface of the eye through the insertion of a lens insert. While there are a variety of different styles and designs available for today’s contact lenses, the most important purpose of these devices is to improve the vision of the wearer by correcting problems with farsightedness (farsightedness affects people as they get older), nearsightedness (nearsighted people see everything clearly, but suffer from blurry vision as a result of their problems), astigmatism (a person suffers from irregularly shaped vision because the corneal surface is irregularly shaped like a football), and presbyopia (acts like those of a pregnant woman, which means the lens of the eye does not allow light to pass through the pupil of the lens and into the retina, causing blurriness and blurry vision). Additionally, many other vision impairments can be corrected with the use of contact lenses.
The most popular method of providing visual correction is with corrective contact lenses, which are much like eyeglasses. However, unlike eyeglasses contacts do not have to be prescribed by an optometrist. There are many places you can go to get same day contact lenses. Simply going to a pharmacy and purchasing the item you need is usually sufficient to provide you with the corrective aids you require. This method allows for a more convenient and more economical approach to obtaining eyewear and will save you the time and trouble of making multiple trips to your optometrist’s office to receive your corrective aids.
As with any other vision correction technique, the effectiveness of contact lenses depends largely on the patient and his or her eyes. As such, you must visit an Optometrist or Ophthalmologist (the medical professional who is best known as an ophthalmologist) for consultation and prescription before deciding whether or not to wear contact lenses. If you already wear contact lenses, your doctor will likely instruct you to wear a protective eye shield during certain visual acuity tests. These tests are performed to determine if you have any problems with your eyesight at night. Your Optometrist will also likely instruct you to not drive after wearing your contact lenses, as well as not perform any outdoor physical activities after dusk.
Although wearing contact lenses is considered a safe and healthy way to treat vision problems, it is still important to be aware of some potential dangers when using your lenses. Although the risk of losing your eyesight while wearing them is infrequent, you must still follow-up care instructions given by your doctor. For instance, you must clean your hands thoroughly before removing the lenses. Likewise, you should not wear dirty or sweaty lenses–these can hinder proper lens function. If you run out of contact lenses or need a fresh pair at the spur of the moment, you will find many places offer same day contact lenses options.
For individuals who frequently wear hard contact lenses, soft contact lenses are often preferred due to the convenience of being able to remove them more easily than hard contact lenses. The biggest advantage of soft contact lenses is that they are generally less uncomfortable. However, it is still necessary to follow certain basic hygiene practices for handling and cleaning these products. Most experts recommend that you should never share your soft contact lenses with other people. Even though this may seem unappealing, it can help to reduce your risk of infection.
In addition to providing improved comfort, silicone-hydrogel contact lenses allow you to adjust the pressure of the lenses so that they are comfortable. As pressure is adjusted, you should change both sides of your eyes at once so that both eyes feel comfortable. In addition, you should avoid rubbing your eyes with your hands, as this can irritate your eyes and lead to pain. It is also recommended that you wash your hands after washing your hands with soap and water, which can irritate your eyes. In addition, you should avoid rubbing your eyes with towels, which can cause irritation and discomfort. If you suffer from dry eyes, you should not wear moisture-based eye makeup as this can make the eyes feel dry as well.
