Contact lenses, also known as soft contact lenses, are tiny thin lenses usually placed directly on the cornea (the topmost layer of the eye). Contact lenses can be either soft lenses, which are made from a protein coating to provide a more rigid surface and thus provide better vision, or rigid gas permeable (RGP) lenses, which have a thicker lens surface and so provide better vision. Contact lenses were invented by a German physician during World War II. Since then, they have become a very popular way of changing your eye color or correcting vision.
Prescribed to you by a doctor or “off-the-shelf”
Contact lenses can either be prescribed to you by a doctor, bought over the counter with a prescription, or you can choose to wear lenses “off-the-shelf”. Some people who wear lenses find that they need to buy some additional contact lenses or their eyes get really sensitive to UV light from the sun. In this case, you might want to contact your optometrist and tell him/her about your special needs so that your eye doctor can order some additional lenses for you. These extra lenses usually cost a bit more than regular lenses, however, you will save money in the long run because you will not have to buy prescription eyeglasses for the rest of your life.
Consult your eye doctor
Some people wear contact lenses to change their eye color. These are called bifocals, which look very much like true eyes. To achieve the better vision while wearing contacts, it is necessary to see an eye doctor who can prescribe you the correct lens for your particular eyesight. However, some people just wear contact lenses for fun. If this is your case, please consult your eye doctor to see if you would need to take any corrective measures.
Cleaning your lens in warm soapy water
You may have noticed that your contact lenses seem to fog up after a while. Wearing contacts causes your eye to produce less of a certain protein that keeps the foggy appearance. You can eliminate this problem by simply taking them off for a while and cleaning your lens in warm soapy water. However, if your fogging occurs more frequently, you should contact your eye doctor and find out what is wrong.
Contact Lenses are a great option for those who do not want to wear glasses or contact lenses for one or more months. Your optometrist can fit you for either regular or extended wear lenses. He will also be able to advise you about replacement schedules for your lenses so that your eyes stay healthy. A good optometrist will make you feel at ease about the process since he is dealing with your vision daily.
Having poor-quality contact lenses results in having blurry vision and decreased comfort. You should therefore invest in high-quality ones to improve your vision. And remember, it is not wise to dispose of your lenses without your eye doctor’s approval. This is because some of your vision correction could be dependent on these items and some may require surgery if they are not properly fitted. Your eye care professional can check for the appropriate contact lenses for your particular condition.
