Contact Lens Questions

Extended wear contact lenses are designed to be slept in. However, it is always best to consult with your optician to see whether extended wear lenses are compatible with your eyes.
Some contact lens wearers do suffer with dry and gritty eyes. Environmental factors such as air conditioning and heating, the position you sit in and the amount of water you drink can also affect your eyes. It could also be the contact lenses you are wearing. For example, Focus Dailies All Day Comfort lenses should not be worn for more than 8 hours a day. However, Acuvue Trueye can be worn for up to 16 hours a day as they are made from silicone hydrogel which allows more oxygen to reach the eye. You can use artificial tear or eye drops as they are better known to help to rewet and moisturise the eye or you can talk to your optician about changing your lenses to suit your lifestyle.
Yes, you can try different contact lenses. However, it is always best to speak to your optician before doing so.
When you receive your contact lens prescription from your optician, you should be informed of the wearing pattern compatible with your lenses. The most common contact lenses are disposed of daily, or cleaned and stored overnight for wear over a two-week or monthly time period. Some contact lenses are designed for extended wear; this means they can be worn continuously for a certain time period. It is not advisable to wear your contact lenses continuously without consulting your optician first as not everyone's eyes are compatible with extended wear lenses.
