Contact lenses

To wear contact lenses is convenient and secure; however this is only the case if we follow the instructions of the producer and the optometrist. Contact lenses can be used in most circumstances; however it is not advised to wear them in saunas, sun beds, dusty surrounding or swimming pools.

Before advising a particular contact lens we warily examine the patient’s eyes with appropriate techniques. This will decide whether the eye is compatible with the contact lens and the type of the lens.

Before the first time of using a contact lens the optometrist or the eye doctor will explain the right way to apply them. When choosing the appropriate contact lens the measured data and the supposed frequency of wearing them will be taken into account.

The most popular types of contact lenses are those which are fortnightly or monthly changeable. These lenses can be used up to 16-18 hours a day. They contain high water quantity therefore the ability to let oxygen through is maximal.

A popular type is the 24-hour lens, which can be used up to 30 days after opening. Silikon-hydrogel ensures the flow of the oxygen.

Apart from this we know:

One-day contact lenses

They are advisable for a single use only. We place them in the morning, take out in the evening and throw them away.

Contact lenses for 14 days, 3 and 6 months.

Those who wishing to correct their sight with contact lenses, usually favor soft lenses. There is an adequate oxygen quantity for the eye all day if soft lenses are used.

According to their lifetime we distinguish between yearly, quarter yearly and monthly changeable lenses. The healthiest option is the monthly changeable lens, which are more cost friendly than we would expect.

The soft contact lens fits the eye very smoothly. After placing the first contact lens on your eye you will usually need 20 to 120 minutes to get used to it. After this time period it is unnoticeable. Nevertheless rarely it can happen that more time is needed than 120 minutes; however the getting use to process does not take more than few days. The advisor can give useful methods in order to shorten this time.

Apart from soft contact lenses we distinguish between gas pervious and firm contact lenses.

The gas pervious contact lens is firm, however produced from plastic. This kind of plastic is more flexible than those used for classic contact lenses. Therefore enables the flow of the oxygen to get through to the cornea.

The firm contact lens belongs to the oldest lens generation; they do not allow the flow of the oxygen to the cornea. There are materials which are more clement therefore they production of firm lenses are not that common any more.

While wearing contact lenses there is a certain amount of dirt which deposits from outside surrounding onto the lens as well as dirt from lipids and proteins which are coming from the tears. These materials can lead to irritation as well as infection. Subsequently it is particularly important that we clean our lenses on a regular basis.
