What's new in contact lenses?
There is a lens to suit virtually everyone. There are lenses you can sleep in, lenses that correct for astigmatism and multifocal lenses for varifocal wearers. New materials are being developed all the time to increase wear and comfort.
Today's contact lenses have virtually eliminated the earlier uncomfortable hard lenses. Hard lenses in the past were made from a material that didn't allow valuable oxygen to pass through to the cornea. They had to be small (to leave the front of the eye as uncovered as possible) and their size often made blinking uncomfortable and allowed the lenses to pop out.
Today's lenses are made from materials that allow oxygen to pass freely to the eye, allowing it to breathe comfortably. They are comfortably held in place by the eye's own natural tears, which are always present between the lens and the eye. This enables the lenses to be bigger, greatly enhancing comfort and peripheral vision, whilst reducing the image distortion that can be caused by some spectacles.
There are many options in contact lens wear, with many price options. The sort that will suit you depends on your eyes, your lifestyle and the cost you wish to pay. The optometrist will discuss the different options with you. We have a monthly standing order scheme for easy payment and access to emergency appointments, 24 hour telephone advice from the optometrist, check ups, 20% off spectacles and a free pair of sunglasses each year.
There is a risk of eye infection and damage to lenses if they are not looked after properly.
- Wash or allow lenses to come into contact with tap water. This can lead to a serious sight threatening infection.
- Use eye medication or drops that have not been recommended by the optometrist
- Use tweezers, suction cups or anything sharp to remove lenses—only clean fingertips
- Swim in your lenses
- Use the contact lens care solutions recommended by your optometrist
- Attend annual check ups so that the optometrist can look for any damage caused by wearing your lenses
- Check your eyes daily - they should feel comfortable, vision should be clear and there should be no redness
- Change contact lenses as frequently as the optometrist recommends as over wearing can cause problems such as soreness and infection. It is advisable to have a pair of spectacles made up to your prescription as a back up if problems occur.
