Contact Lenses, also known as pure lenses, are thin, curved lenses placed directly on your eyes. Contact Lenses are amazing ocular prosthetics, used by more than 150 million individuals worldwide, and they are worn to correcting vision for corrective, aesthetic or therapeutic reasons or for personal or cosmetic reasons. The average age of a first-time buyer of contact lens is 20 years old. Although the process to get an affordable pair of contact lens is somewhat complicated, if you follow some simple steps it should be relatively painless.
The first step to buying your first pair of contact lenses is to visit an eye doctor. If you have vision problems and/or are pregnant, you should avoid purchasing your first set of lenses online or from a retail outlet as contact lenses must be prescribed by an eye doctor. There are many different types and styles of contact lenses available and many online merchants will not sell to individuals without a prescription. In the event that your eye doctor prescribes the lenses for you would like to try out the pair(s), he or she may provide you with a small portion of the pair at no charge as a trial, however you must keep the contact lenses in your eye at all times.
Once you have received a prescription for the contact lenses you wish to purchase, you can visit a local optometrist or ophthalmology office where you will be fitted for the lenses. You will be given instructions on how to put the lenses in your eye correctly. If you wear contact lenses for cosmetic or practical reasons, you may be instructed to remove them once you are finished using them. If you do not remove them when instructed, the lenses may get accumulated behind the cornea and cause vision issues. If you notice that your eyes are red, puffy, sore or bruised, you should contact your eye doctor immediately and find out what can be done to alleviate the problem.
Some people who wear contact lenses to correct their vision correction need only to wear them twice daily for twenty minutes each time, while others who have more serious vision correction issues will need to wear contact lenses for up to thirty minutes daily. Most people who wear contact lenses for decorative purposes only choose to wear them during the day, but there are some soft contact lenses that are made especially for evening, daytime and even swimming use. When selecting soft contact lens wearers must take into account if they will be using the lenses at night that they need to consider the degree of softness and permeability of the lens material. It is also very important that the contact lenses are prescribed by a licensed eye doctor.
As a general rule, it is advisable to wear contact lenses that are thinner in the center than they are wide. This allows greater transfer of oxygen to the cornea, which flake’s are more susceptible to damage caused by rubbing against the cornea. If one is prone to scratches or abrasions near the cornea, it is advisable to purchase a soft lens with a little more permeability so that the scratches can be reduced. Most soft contact lenses can be discarded at the end of the day, if desired, because they do not retain any water.
To maintain the best eye care possible, it is recommended that one avoid rubbing their eyes, which could aggravate eye problems. One should wash their hands with soap and water before putting on their contacts, as this will minimize the risk of bacteria and viruses being transferred between the contact lens and the skin. It is also very important to be very careful when moving from one room to another, especially if wearing different types of contacts at the same time. One should always rinse their hands thoroughly after putting on or taking off a lens, as dirt and bacteria can get onto the lens and enter the eye, which could cause an infection. By following these simple precautions, anyone with an eye problem can enjoy great results with their eye care treatments.
