Types Of Contact Lenses And Their Uses
First recognized in 1945, contact lenses have become a necessity for millions of people. Contact lenses are worn to correct vision and enhance appearance. Many people who are keen to change their eye colour wear colour-changing lenses. People with low vision also prefer to wear contacts as they facilitate a clearer vision in comparison to those bulky glasses. This is because the lens lies flat on the eye while spectacles sit above a few millimetres above the eye.
In the U.S.A., it is compulsory to show a prescription for lenses by a licensed eye doctor at pharmacies. Getting a prescription from the doctor can be expensive. However, at Lenskart one can easily buy contact lenses without any prescription. The website sells all types of lenses at discounted prices. Whether you have a prescription or not, your lens will be delivered to you at your doorstep. Following are some types of lenses and their uses.
Daily Disposable Contact Lenses
As the name suggests, daily disposable contact lenses are the type of lenses that are disposed of after single use. People who have allergies or have sensitive eyes should opt for these. The benefit of these lenses is that one does not need to clean them at all. People who are just starting to wear lenses should initially go for disposable lenses. One can wear these lenses for up to eighteen hours.
Two Week Disposable Contact Lenses
This type of lens can be worn for two weeks, daily. You will need to remove these lenses before sleeping and store them in lens solution for using them the next day. People wear these, as they are affordable. These lenses are made of silicone hydrogel material, which is very comfortable to the eyes.
Monthly Contact Lenses
These lenses can be worn daily for thirty days. They should be taken off before sleeping and demand proper cleaning and disinfection. Once you get in a habit of wearing lens, you can choose to wear monthly contacts, as they are more cost-effective than daily disposable ones.
Extended Wear Contact Lenses
Removing the lens every day and disinfecting them is a hassle for many people. For those, extended-wear contacts are created. They require minimum cleaning and maintenance. One can wear these contacts throughout the day and night straight for seven to thirty days.
Coloured Contact Lenses
These lenses change the colour of eyes while correcting far-sightedness, near-sightedness, or astigmatism. These lenses are always high in demand as many people desire for different eye colour. You can temporarily change your eye colour completely or enhance the tint of your eye colour.
Multifocal Contact Lenses
People who have a combination of far-sightedness and near-sightedness can choose to wear multifocal lenses. Just like multifocal glasses, these lenses will help you see objects at any distance clearly. You would not need to maintain a separate pair of glasses for reading if you buy yourself multifocal contacts.
However, it is recommended to consult an eye doctor if you are buying lenses for the first time or changing your brand.
