Contact lenses are God-given gifts if you are someone who hates wearing glasses. They are an excellent choice for anyone who needs vision correction but doesn’t want to undergo surgeries for that purpose. The concept of contact lenses was first introduced by Leonardo da Vinci in 1508. In the following centuries, contact lenses were made from glass and then from plastic, making them a nightmare to wear. The modern soft contact lenses originated only in 1971.
It is very important to choose your contact lenses carefully so they don’t create problems for you. The first thing to check is why you need vision correction. It is important to consider your options with respect to myopia, hypermetropia, astigmatism etc. Cylindrical and axial powers also play a major role in the type of lenses you could choose from.
The second thing to check is the material with which the lenses are made. There are many types like the rigid PMMA lenses, Gas Permeable lenses, Soft lenses, Silicone hydrogel lenses, and Hybrid contact lenses. Soft lenses and silicone hydrogel lenses are the most comfortable to use. They almost always fit the user’s eyes perfectly. PMMA lenses are things of the past these days as they are made of rigid plastic and are difficult to adapt to since they don’t allow oxygen contact to your cornea. They are replaced by porous Gas permeable lenses which allow oxygen to come in contact with the cornea but are also quite rigid. This type of lens is especially useful to someone who needs correction to astigmatism. Hybrid contact lenses are designed to provide wearing comfort that rivals soft or silicone hydrogel lenses, combined with the crystal-clear optics of gas permeable lenses. But these are too expensive to replace compared to the soft options available.
The third thing to consider is your daily usage. You have different options like extended wear lenses that can be worn overnight, planned replacement lenses that need to be replaced once in a few weeks, coloured lenses if you prefer them to add some character to you. In fact, coloured lenses are much more preferred these days and are manufactured by a lot of contact lens manufacturers. For example, Amara lenses is one of the leading manufacturers and their solotica hidrocor avela which is a beautiful hazelnut colour is a hit among youngsters and older people alike.
While soft lenses are more comfortable to wear than rigid gas permeable (RGP) lenses, they also come with a set of disadvantages. Irritants from your hands and environmental pollutants transfer easily when it comes to soft gel lenses. They are much more fragile and hence, they are easy to rip and tear. RGP lenses, while they are pretty difficult to adapt to, provide sharper vision than soft lenses. They require higher maintenance and greater care but may save your money in the longer run.
Contact lenses have become safer to wear these days but it is still important to care for them. Always wash your hands with a mild soap before you come in contact with your lens. Keep your nails short to avoid damage to both your eyes as well as your lens. Strictly follow the recommended time to wear your contact lenses; avoid prolonged contact. Clean them with a good lens-cleaning solution before wearing your lens and after taking them off. Contact lenses last longer depending on how you care for them.
