Enter your current contacts into the 'Switch & Save Widget' and find out.
An aspheric contact lens is not quite spherical in shape and has a varying curve on the surface of the lens, changing the power gradually from the center to the outer edge, this helps to focus the light entering the eye which can provide clearer crisper vision with fewer distortions and blurring.
Aspheric contacts can also be used to correct small amounts of astigmatism and help early stages of presbyopia.
Although aspheric contacts can correct a small amount of astigmatism they are not an astigmatic lens also known as a Toric lens.
Aspheric contacts are primarily designed to correct spherical aberrations that can be found on contact lenses or the human eye, the shape of the aspheric contacts and the gradual power change from the center out, helps focus the light entering the eye reducing distortion and providing clearer, crisper vision.
A Toric contact lens is specifically designed for people who have astigmatism - where the shape of the eye is not a perfect curve - a Toric contacts need to have two powers, one to correct the vision and one to correct the amount of astigmatism.
A Toric contact lens needs to remain stable to provide clear, crisp vision, as most contacts move and rotate as you blink, a Toric contact lens needs to be stabalized, manufactures do this in a number of ways

The Biomedics55 I ordered came in a mock-looking box, somewhat unlike the original box I saved from the last supply purchased here in the US. The quality of the lens are thinner than the ones I`ve used (for several years) and easily slip around--I don`t think they will last as well as the originals. I will wear them, but I can`t believe they are from the Biomedics company. The order was late, but customer service was good nonetheless as they kept me informed.
Editor: Coopervision have repackaged Biomedics 55 several times, so they can come in different boxes. The latest box is the Biomedics 55 evolution. However, the lenses remain the same. If they are slipping around, make sure that you have ordered the correct radius as your previous lenses, and that they have not been inserted inside out. All lenses that are supplied are genuine manufacturers products.
I have worn focus monthly visitint and softlens 59 both without any problems but I decided to try a new brand as I sometimes do. These lenses work great day 1-7, after that they are a pain to put in as they never sit right and then at the end of the day they are so dry it is horrible. Nearer the end of the month they will be uncomfortable all day and make your eyes itch. I don't know if it is just my eyes, but I REALLY hated these lenses when comparing them to the ones I usually use.
STRAIGHT TO THE CHASE, THESE ARE THE WORST LENSES I HAVE EVER HAD THE MISFORTUNE OF WEARING. I HAVE BEEN WEARING CONTACT LENSES SINCE 1994, THAT'S 18 YEARS OF BASICALLY EXPERIMENTING WITH ALMOST EVERY LENS ON THE MARKET, 3 MONTHLY, 1 MONTHLY, ONE DAY DISPOSABLE, CONTINUOUS WEAR ETC ETC I HAVE ALWAYS WORN MY LENSES WELL PAST THE RECOMMENDED TIME FRAME (I'VE WORN MONTHLY LENSES FOR OVER 4 MONTHS AND DAILY LENSES FOR A WEEK PLUS!!) THE POINT IS I'VE TESTED MY EYES TO THE LIMIT IN TERMS OF WHAT THEY CAN DEAL WITH. I POINT ALL THIS OUT SIMPLY TO SET THE SCENE TO EXPLAIN JUST HOW BAD THESE LENSES ARE.
THE ARE SO FLIMSY IT TAKES AN AGE TO GET THEM INTO THE EYE AS THEY JUST COLLAPSE ON YOUR FINGER PRIOR TO INSERTION.... WITH ANY OTHER LENS I RARELY TAKE MORE THAN A COUPLE OF SECONDS AND WITHOUT MIRROR). THEY RAPIDLY DETERIORATE WELL BEFORE THE 4 WEEKS HAS EXPIRED; THEY DRY OUT FREQUENTLY; TEAR EASILY; DEVELOP PROTEIN DEPOSITS AND BECOME GENERALLY UNUSABLE AFTER ABOUT TWO WEEKS OR LESS... THE AMOUNT OF TIMES I HAVE BEEN LET DOWN BY THESE LENSES IN THE PAST 6 MONTHS IS BEYOND A JOKE AND I'VE BEEN LEFT CURSING THE DAY I BOUGHT THEM ( AND LEFT HALF BLIND WHERE THEY HAVE TORN, FELL OUT ETC ETC....IN THE MOST INCONVENIENT OF PLACES. PLEASE DO NOT EVER BUY THESE, THEY REALLY ARE A TERRIBLE TERRIBLE PRODUCT. (ZERO STARS)
I wear these lenses for few years now and would not want to change to anything else. Regular eye checks give me all clear to continue using them. I wear them for weeks sometimes, only removing for a night every two weeks or so. (not recommended by opticians!) Even so, never had any issue or discomfort - sometimes I simply forget that I am short sighted!
These lenses are excellent for the first few days but they deteriorate far too quickly and seem to become progressively less efficient, so I tend to dump them after only 2 weeks wear and start over with a fresh pair. Cheap but not cheap! They don`t provide good comfort in air conditioned environments, drying out fairly easily. Fold into the eye and disappear at the slightest touch. I`ve given up on these lenses.
I have tried these lenses (not from this site I may add - i was given them free by an optcian!). And I found them to be fairly comfortable to start off with, - but are not good for extended wear. After I have had them in all day - they crinkle up in my eye. My eyes become iratated - and `get lost` easily within my eye - once they are all crinkled!
So would be great for a few hours wear, or a normal working day but not good for extended use
