Can Biofinity Toric be worn overnight?
If you are wondering, “Can I sleep in the Biofinity toric contacts?”… the answer is yes. According to manufacturer instructions, Biofinity toric and Biofinity XR toric lenses may be worn up to a maximum of six nights/seven days. However, not everyone’s eyes can tolerate overnight wear of contact lenses.
What are the parameters of Biofinity toric XR?
Biofinity® XR toric lenses are available in sphere powers from +10.00D to -10.00D (0.50D steps after +/-6.00D), with cylinder powers from -2.75 to -5.75 (0.50 steps) and an axis of 5 degrees to 180 degrees in 5-degree steps.
What is base curve in contact lenses?
The base curve of a contact lens is the curvature of the back surface of the lens. It determines the type of fit the lens must have to match the natural curvature of your eye. Typical base curve values range between 8.0 and 10.0 mm, though it can be flatter (from 7.0mm) if you have a rigid gas-permeable lens.
How does a toric lens work?
A toric lens is shaped like a slice of the side of this donut. The shape of toric contact lenses creates different refractive, or focusing, powers on the vertical and horizontal orientations. The refractive strength increases or decreases gradually as you move around the lens.
Can you shower with Biofinity contacts?
Just like swimming with contacts, showering with your contact lenses isn’t a great idea. Contact lenses are like sponges that absorb what they come in contact with. The tap water in your home can contain microbes that you don’t want in your eyes.
How many hours can you wear Biofinity contacts?
Biofinity® lenses are designed for daily wear for 30 days, which means they should be cleaned and stored overnight. They can also be worn continuously for 29 nights if approved by your optician.
How do I know my base curve?
Simple Rule for estimating lens base curve on a PLUS POWER lens
- For plus power use the spherical equivalent (SE) and add 4.00 diopters to that. For example, if you have an Rx of + 2.00 sphere, the base curve for the lens will be approximately 6.00.
- Rx +2.00Sph -> [+2.00 +4.00D] = 6.00BC.
