Examination for eyeglasses and contact lens prescriptions

When you start to realize that you are constantly straining your eyes and no longer see as clearly, whether this be when viewing objects from near or far, it is futile to hope that your eyesight will improve again on its own. If you also suffer from headaches, it is high time to stop tiring your eyes and be sure to get a correct dioptre measurement.

Measuring the value of your dioptre

An examination for prescribing eyeglasses is usually part of a complete general ocular check-up, unless it is performed solely for the purpose of getting new glasses. In this case, it is sufficient to estimate visual acuity and to determine the dioptre value using a refractometer. For all examinations, we use only the latest equipment that enables very precise measurements. The final dioptre value for eyeglasses or contact lenses is prescribed according to your own subjective judgment of the quality of vision which you evaluate by trying on corrective glasses with different vergencies. The final dioptre value will undoubtedly be correctly measured at our centre. And you will also make the right decision by taking advantage of the expertise of our opticians at our MOOP optical clinic by letting them help you select the type of glass and frames that are most suitable for your face and lifestyle.

    My former optician diagnosed me with 90% vision, citing it would worsen over time. Morela Ophthalmologists discovered an error in the diagnosis and corrected it with the correct dioptre prescription. Today, I see perfectly without suffering continuous headaches and will gladly go back to Morela Ophthalmologists. Thank you Morela!

  • Performing eye measurements
    Duration: 10 minutes

    Similar to an examination that is performed due to the onset of other eye problems, an examination for prescribing eyeglasses or contact lenses is performed by first measuring dioptric value and intraocular pressure. For individuals who already wear eyeglasses, we also determine the dioptre of the eyeglasses they are wearing. We advise individuals who wear contact lenses not to wear them at least two days prior to the examination. If possible, you should bring the results from your last optometry examination with information on the contact lenses that were prescribed.

  • Determining visual acuity
    Duration: 10 minutes

    In order to evaluate your eyesight, it is very important to determine visual acuity both with and without corrective eyeglasses. This allows us to determine whether the cause of your worsening eyesight is due only to refractive error or whether it is caused by eye disease or innate visual impairment (undeveloped vision). In the latter two cases, a specialist ophthalmologic examination during which we clarify the cause of your poor vision is usually necessary.

  • Eye examination
    Duration: 10 minutes

    An eye examination using a biomicroscope is also always performed when prescribing eyeglasses or contact lenses. This examination allows us to evaluate the state of the cornea, which is particularly important in those who frequently use contact lenses. During this examination, we always make the time to discuss the needs and expectations of every individual as concerns their eyesight. This enables us to provide the best advice to each person who is deciding on a type of corrective glasses and/or contact lenses.

  • Evaluating vision using test eyeglasses or contact lenses
    Duration: 10 minutes

    Before finally prescribing eyeglasses or contact lenses, we normally evaluate each patient's vision using test eyeglasses. By testing vision under different types of lighting conditions and by looking at various distances, also while performing movement, we can obtain much more reliable data on the suitability of the chosen dioptre, which ensures that the correct eyeglasses are produced.



What is the main difference between soft, semi-hard and hard lenses?

The difference between them is in the type of the material that they are made from. Soft lenses are made from material that is most permeable to oxygen, which is why they are most comfortable to wear. These types of lenses are used by 99 percent of those who wear contact lenses. Semi-hard lenses are less permeable to oxygen and are used primarily by patients who suffer from keratoconus or high degrees of astigmatism that are not possible to correct with soft lenses. Hard lenses are no longer used because they have been entirely replaced by semi-hard lenses.

Which lens is the most suitable for me?

We cannot provide an answer to this question in advance and there is no general answer. People are different from one another and each person has individual needs. This is why we select the most suitable contact lenses for every person on the basis of an eye examination and a discussion about their lifestyle.

Can I use soft contact lenses if I suffer from astigmatism?

Yes. There are different types of daily, 14-day and monthly soft disposable contact lenses to correct astigmatism.

What is the risk of using 14-day contact lenses for one month?

The oxygen permeability of contact lenses decreases over longer use, so that more and more proteins and lipids accumulate from teardrops. This increases the risk of developing bacterial cornea infection. Due to there being a worse provision of oxygen for the cornea, chronic changes in the form of an expansion of thin arteries that gradually damage the cornea can occur. This happens because the body tries to improve the provision of oxygen to the corneal tissue. We cannot see this with the naked eye but it can clearly be seen in many long-term contact lens users under a microscope.
