The principle of glasses is the same as for contact lenses. They bend light and redirect it towards your retina to improve your eyesight.
Glasses are fashionable and popular. Compared with early models they are more light, flexible and strong. Today’s plastic lenses can be as scratchproof as glass but because they weigh very little, are more comfortable.
Which type of glasses should I wear?
Your optician will test your eyes to find the right prescription to correct your vision with glasses. He or she may recommend:
- Single-vision lenses for long-sightedness or short-sightedness.
- Progressive (varifocal) or multifocal lenses for presbyopia.
There may also be different coatings added to your prescription glasses’ lenses, such as:
- Anti-reflection, which is good for computer use and night driving.
- Anti-scratch to protect your glasses from damage.
- Permanently tinted or tint that turns your lenses darker in the sun (photocromic lenses).
There are also some special prescription glasses available for specific sports.
Your optician will also be able to advise you on which type of glasses will suit you. These days there are so many styles of frames you may want to take a friend to help you choose the style that suits your face best.
Contact lenses and glasses
Many people use both contact lenses and glasses, alternating between them depending on what they are doing. Even if you wear contact lenses most of the time, it is advisable to carry a pair of glasses with you in case you have to take your contact lenses out.
It is important to visit an optician for a proper eye test to ensure you have the right prescription and vision correction option for your vision needs.
If you are planning on getting glasses, ask your optician about contact lenses too, so you can be sure you have discussed all the vision correction options that are available to suit your lifestyle and vision needs.
