What are contact lenses?

Contact lenses are thin pieces of plastic that are placed directly on the eye to correct certain vision problems . Contact lenses are the ideal vision correction solution for those who do not want to wear glasses and / or undergo corrective surgery. Millions of people wear contact lenses, especially those who are active and want clear, clear vision without having to wear glasses on their face. Most people can wear contact lenses and enjoy their freedom of vision without the aid of glasses.

Contact Exam

If you want to wear contact lenses, the first step is to see your eye doctor for a contact lens exam . A contact lens exam is specifically designed to help you find the right contact lenses for you. If you plan to have a contact lens exam, prepare for a longer exam than you are used to. This type of examination is thorough and has several stages. By examining contact lenses, your doctor will first determine if your eyes are healthy enough to wear contact lenses. Since contact lenses actually touch and cover your eyes, your eyes should be as healthy as possible before trying to wear them. Then your eyes will be measured. Your ophthalmologist will try to get the most accurate measurements possible. These precise measurements will help your doctor find the correct contact lenses that will fit your eyes correctly and comfortably. If you are new to wearing contact lenses , your healthcare professional will teach you how to insert and remove contact lenses from your eyes. It will help you practice and get used to putting on and taking off the lenses yourself. You will then be taught how to properly care for them, including cleaning and storage.

Contact types

There are two main groups of contacts: soft contacts and hard gas permeable contacts. The soft contacts are very thin and comfortable to wear. They are composed mainly of water, so they are soft. Soft lenses are divided into four main categories: spherical (regular) lenses, astigmatism lenses, presbyopia , and colored (cosmetic) lenses. Rigid gas permeable contact lenses are made of hard plastic that provides crisp, clear vision and eliminates most vision problems. They are durable and last much longer than soft lenses.

Contact wear and replacement program

Some contacts are designed for everyday wear. Soft, everyday contacts are worn for one day and then discarded. Other soft lenses and some RGP lenses are worn during the day and then removed, cleaned, and disinfected each night. Soft lenses are usually replaced regularly. RGP lenses can last for years with regular care. Long-term contact lenses are worn overnight for a week and then replaced. Nightwear reduces the amount of oxygen available to the eyes and increases the chance of infection. For this reason, some doctors do not recommend long-term contact lens wear . Scleral contact lenses are becoming more and more popular and are a good option for people with sensitive eyes.

Get the word of drug information

Your ophthalmologist will show you how to clean and disinfect contact lenses. Use quality lens care products and clean your lenses as often as possible to remove bacteria buildup. Remember that wearing contact lenses for long periods can be dangerous. Overuse can cause problems like blurred vision, pain, and redness due to lack of oxygen entering the eyes. Remember, contact lenses are medical devices that should be taken seriously. However, with proper care, you will see better and have the peace of mind of knowing that your contact lenses are healthy and safe for your eyes.
