Best Contact Lenses

It’s import ant that your Prescription Contact Lens details are up to date as you will need them to compare and get the best value on line.

Also you may have noticed it’s different to your glasses, so it’s unique to your eyes and you must never use a friend’s prescription who seems to have similar vision, to buy online. 

First off there are 2 columns headed OS for the Left eye and OD for the Right; and you can also get OU which means the numbers are the same for both eyes. 

The other main headings are:

Power (PWR), which is the strength of contact lens you need, such as – 1:00, -1:75, + 2:00, + 3:00

Base Curve (BC) the inside curve of your contact lens, e.g. 8.6

Diameter (DIA) size of your contact lenses; 13:8, 14:2

Brand: Here you may want to see a major brand such as Acuvue, Johnson & Johnson and Focus. Then you can compare prices for the best deal online.

Add Power (ADD) A measurement of power for multifocal lenses that will help you with close up reading

Cylinder (CYL) is the strength of your astigmatism – 1:00, – 1:25 if you need it.

Axis (AXIS) is the orientation of your astigmatism such as 170 and compensates for the oval shape of your cornea and should improve your blurry vision.

Other stuff to look out for on your Prescription Contact Lens form is the expiry data which is typically 2 years and there will be a note on colours if you want tinted or colour contact lenses.

What can I do if my eyes are dry after wearing a prescription contact lens?

You may find that your eyes feel dry after long periods of wearing contacts. Initially try some of the artificial tear solutions that are approved for contact wearers and maybe go back to using glasses for a couple of days.

If the problem is still around it may be best to see your eye doctor and consider changing your contact lenses or your wear schedule to daily disposable lenses

What happens if I put two contact lenses into the same solution compartment?

Many people have pairs of clear and colored lenses, but you should always keep them separate.

If they are cleaned together they sometimes stick and the cleaning process just does not work properly, leaving harmful residue on the lens surface.

Can you swim with contacts?

Sometimes your eyes can become irritated and the pool water can damage your lenses. Not everyone seems to have a problem, so it you want to try it with lenses, best to use a good pair of tight fitting goggles, especially in chlorinated pools.

What happens if you sleep in prescription contact lenses?

Fine if they are designed for overnight wear, such as Acuvue Oasys, as they have very high oxygen permeability, for healthy eyes. If it happens very occasionally with your Daily’s then your eyes may feel very dry the next day as the lens isn’t designed to let through the essential oxygen. Best to stick to the wear schedule

How long does a prescription contact lens last?

In short there are 2 dates to look out for. When you receive your box of lenses, there will be an expiry date on them – say 20 Dec 2012. Then there is the life of the lenses once the individual seal is broken i.e. Daily, 14 or 30 day etc.
