Frequently Asked Questions

Hypermetropia is an optical condition in which the image of a distant object is focused virtually behind the retina, either because the eye length is small or because the refractive power of the eye is poor. This condition causes near objects to appear out of focus.

If you have hyperopia, it is recommended that you go to your optician for regular check-ups.

Astigmatism is a condition (which can be combined with the previous ones) in which the ocular refractive power is different depending on the meridian considered. This generates a noticeable blur at all distances. It usually causes cross distortion and a clear symptom can be glare from lights, especially when driving at night.

If you have Astigmatism, it is recommended that you go for regular check-ups with your optician-optometrist.

Presbyopia is a defect caused by the inability to focus in near vision, which usually manifests itself after the age of 40: the lens that changes its shape to achieve near focus (the crystalline lens) loses its flexibility and stops performing its function properly.

Nowadays, thanks to a better understanding of the needs of the visual system in each case, as well as the enormous development of manufacturing techniques and materials, almost all patients enjoy a great visual comfort and a quick adaptation to progressive lenses.
However, these undoubted improvements do not guarantee the adaptation of all patients, they only make it easier. For each presbyopic individual, a complete visual examination by the optician is the essential tool for the practitioner to decide on the best lens type for a satisfactory fit. In the case of progressive lenses, it is also of vital importance the centering of the lenses once the frame of the glasses has been chosen.
At Interoptics we do a thorough visual examination to know the different needs of each presbyoptist. We have a great experience in advising and taking measurements of progressive lenses and also, we always work with the highest quality, we do not gamble.

According to experts, the excessive use of digital devices can cause the so-called Visual Computer Syndrome, discomfort related mainly to vision, cervical muscles, wrists, stress and irritability.
Starting from the fact that, nowadays, we look at our cell phones an average of 50 times a day, in many occasions as soon as we get up in the morning and just before going to bed at night, we spend an average of 6 hours a day in front of a digital screen and we have an average of 6 devices per person, we cannot deny how present digital devices are in our daily life and the truth is that our eyes notice it. If you use digital devices more than two hours a day do not forget to check your eyes.
The main symptoms of computer vision syndrome are:

• Blurred vision.
• Double vision.
• Ocular fatigue.
• Intense light phobia.
• Tearing.
• Ocular dryness.
• Red eyes.
• Stiffness and pain in shoulders, neck, back, arms, wrists and hands.
• Facial itching and swelling.
• Headaches, nausea, dizziness and vertigo.

At Interoptics we specialize in the effects of the use of digital devices on visual health and vision, if you have any further questions or doubts we will be happy to help you.
