Some people consider their personality to be their most important asset. If you are such a person, then lenses may be the answer to your problem in eye care as they are practically invisible. Contact lenses make sense for people who do not think this way too. Once you get used to them, they are not as bothersome as spectacles.
Contact lenses are available in soft and hard varieties. They are usually made of different types of polymers and they also contain silicone hydrogel which is water soluble. This makes the lens flexible and suitable to put inside your eyes.
These days contact lenses are made of hydrophilic or water absorbing materials. It permits the oxygen to reach your eyes through the lenses itself and it makes lenses comfortable to use. Earlier, lenses were made of a polymer called PMMA. However, currently they have been replaced by rigid gas permeable contacts.
In some cases, contact lenses are the best prescription the doctor can give. This is usually the case when a patient suffers from keratoconus and aniseikonia. Eye glasses are especially dangerous when you are involved in physical activities like sports etc. In such cases, lenses are sensible as they provide a wide field of vision which is required in sports.
You can buy contact lenses online and this is the cheapest way. It is certainly cheaper than buying it from a doctor’s office. However, when you are buying contact lenses online, you must make sure to check the reputation of the distributor.
One tell-tale sign is when they check the doctor’s prescription that you have and verify it with the doctor to make sure the correct lenses are delivered to you so that you do not have any hassles.
There are many online websites from where you can buy lenses and the speed of delivery is also fast and they deliver right to your doorstep which is quite convenient.
