Hard lenses or soft? Daily disposable or reusable? With so many different types of contact lenses available how do you choose?
What are the different types of contact lenses?
We can group contact lenses by the material they’re made from (hard or soft) and how long you wear them for. Lenses will also be prescribed by your optician based on your vision problem.
Soft lenses and hard lenses: the difference
Before you can start wearing soft lenses or hard lenses, you will need to book a contact lens appointment at your local practice. When you visit us the optician will carry out examinations to check that you do not have any problems that might make it difficult for you to wear lenses and advise you about the type of lenses that are most appropriate for your physiology (cornea, how dry your eyes are, etc.). This consultation is essential.After this consultation, you can try out your first lenses. Hard lenses last a long time, and can correct all types of vision problems, from the most common to the most extreme (e.g. irregular astigmatism). However, hard lenses require perseverance, as they take longer to get used to than soft lenses.If your vision problem is more common, soft lenses will certainly be the most appropriate for you. You will discover that it takes much less time to get used to them than to hard lenses, and right away you will find that they are pleasant to wear.Most contact lenses today are soft lenses or ‘hydrophilic lenses’ which means they stay moist and soft. Soft lenses are extremely thin and made from materials that allow oxygen to pass through them to the eye.
There are 3 types of soft contact lenses:
Contact lenses for myopia and hyperopia are spherical lenses. They correct basic vision problems including short-sightedness (myopia) and long-sightedness (hyperopia).Contact lenses for astigmatism are toric lenses. They correct astigmatism by compensating for the irregular surface of the eye.Contact lenses for presbyopia are bifocal or multifocal contact lenses. They are used to correct presbyopia (the inability to focus sharply for near vision).
