Contact lenses are popular alternatives to spectacles. Read on to learn how to care for these useful vision aids and take care of your eye health.
There are two types of contact lenses, i.e., rigid gas permeable (RGP) and soft:
RGP lenses are made of special firmer plastics suited for the passage of oxygen and other gases. These lenses are durable and typically last longer than soft lenses. They offer excellent vision and are often preferred by people with high degrees of astigmatism. However, they may need a longer time to get used to. Regular users find them easy to put on and to care for.
Soft contact lenses are made from flexible water-absorbent plastics. Some soft contact lenses are designed to be thrown away daily, weekly, biweekly or monthly (known as disposable or planned replacement lenses). Others can be used for up to a year (known as conventional soft lenses). Soft lenses require a very short adaptation period and are more comfortable to wear. They are usually easy to insert and fit comfortably and securely.
Your contact lens practitioner will advise you on the most suitable lenses which cater to your needs and suits your particular lifestyle.
American Optometric Association recommends you replace your contact lens storage case at least every three months. Your contact lens solution manufacturer may recommend replacement at anywhere between one and three months of use.
If you experience any of the signs below, contact your contact lens practitioner as soon as possible:
If you experience any other problems with your contact lenses, contact your contact lens practitioner as soon as possible. Stop wearing contact lenses immediately until you have seen your contact lens practitioner.
It is essential to follow your contact lens practitioner's advice on the lens care regime required. It is important to use the products prescribed by your contact lens practitioner, as some products are made for use with different types of contact lenses. What cleans one type may well damage another.
Personal wear and care regimens may depend upon the type of contact lenses prescribed, the nature of the vision problem being corrected, and the individual's unique eye chemistry.
The basic steps include cleaning, rinsing and disinfecting/storing to keep soft contact lenses clean, comfortable and free from bacteria. Weekly enzyme cleaning helps to maintain soft lenses free from deposits of protein naturally produced in your eyes and carried by your tears.
RGP lenses utilise a conditioning and cleaning regiment for effective cleaning, storing and comfortable wear. Daily disposable contact lenses require minimal care and are designed to be worn for a single day then thrown away and replaced by a new pair. For other disposable contact lenses, it is important to adhere to the recommended daily care regime and to dispose of the lenses at the appropriate intervals.
