Yes, light is the natural agent that stimulates sight and makes things visible but part of it can be harmful.
Invisible UV rays constitutes about 10% of the total light output of the Sun, and is thus present in sunlight. UV rays are classified as UVA, UVB and UVC, most UVC is absorbed by the ozone layer and does not reach the earth but both UVA and UVB, however, penetrate the atmosphere and play an important role in conditions such as premature skin aging and eye damage (including cataracts).
Spending just two consecutive hours on a digital device can cause eyestrain and fatigue. Sources include digital screens (TVs, computers, laptops, smart phones and tablets), electronic devices, and fluorescent and LED lighting.
Sorry, but no. It’s not that we don’t want to help you, but it would be irresponsible to try to diagnose your problem without examining your eyes. Please refer to your eye specialist.
“6/6” is commonly accepted as the standard of normal distance vision for a human being. Basically it means that one have a good visual acuity at 6 meter. So if your vision is 6/6, you can read certain sizes of letters on a Snellen chart clearly at 6 meter or closer.
Better known as glasses, ophthalmic lenses are designed to correct the refractive errors or vision disorders.
Mineral glass was considered to be the premium material for manufacturing lenses for a long time. However, times change. Today, lenses are made almost exclusively of high-tech plastics, which are superior to mineral glass in almost all ways. Plastic lenses are:
- Lightweight (compared to glass lenses)
- Shatter-resistant (more than glass lenses)
- 50% safer than glass lenses
- Compressible for extreme vision impairments
A UV 400 lens absorbs and prevents the passage of UV rays, which are regarded as the most dangerous rays the eye can be exposed to.
The purpose of coating on a lens is to reduce reflections from the lens’ surface and ensure clear vision at all times. Three types of coating are available: Anti-reflective coating, hydrophobic coating and scratch resistant coating.
Anti-reflective coating reduces the reflection of the lenses themselves and the glare, allowing for a better and clearer vision.
Hydrophobic coating is characterized by its ability to easily clean the lens thanks to rolling droplets, which keep it transparent and hydrated, It also prevents smudges, and dustiness.
Scratch-resistant coating protects ophthalmic lenses from scratches, increasing their supposed life span. It is especially recommended for very active people such as children and athletes.
People with impaired vision should have their eyes checked periodically. Below is a recommended eye exam schedule for normal cases that don’t include any chronic illnesses:
- For children under 7 years of age: every 6 months
- For children aged 8 to 15 years: every year
- For adults aged 16 to 35 years: every year
- For people over 40 years of age: every year
- For people over 60 years of age: every 6 months
Suntech lenses are high-quality lenses that allow their wearers to move from a sunny to a darker place and vice versa with the utmost freedom and without the need to change glasses. They adapt to the amount of light available to provide the wearer with the best vision at all times.
No, ophthalmic lenses have many characteristics, which must be made by your specialist, who is fully capable of properly dispense it in your frame. For this reason, ophthalmic lenses are traded only with opticians.
It is only recommended to use a HI-Q microfiber cleaning cloth came along with you lens, do not use any other solvents, chemicals or third party cleaning kits because they have not been tested on our lenses and can possibly damage them.
HI-Q is committed to delivering the highest level of performance with every product. HI-Q adapted testing for optical and impact properties from standard methods found in industrial standards like ANSI Z80.1

As soon as you are no longer wearing your glasses, the best thing is to put them in a hard shell case. If you don’t have a case, then always keep them in a safe location with the lens side up.
Avoid very high temperatures, approximately as of 80°C. Neither lenses nor frames like to spend too much time in the sauna or on the dashboard of your car in the summer. In contrast, there are no known negative effects for use in the winter in temperatures that are below zero.
The easiest and most gentle way to clean your spectacles is with some washing up under running water. Afterwards, the best thing is to rub the glasses with a microfiber cloth. Please don’t rub them with a T-shirt or paper tissue. Scratches cannot be removed from plastic lenses. Even if the flaw seems to be only cosmetic, light is scattered by the micro-fine scratches, which irritates the eye.
Unfortunately not. Lenses are not just one pane of glass or plastic, rather a complex system of layers for anti-reflection, tinting and other additional functions. Therefore “polishing out” scratches don’t work. Scratched glasses should be replaced soon. The micro-fine scratches cause light to scatter. The eye has to correct constantly which leads to fatigue. Headaches may be the consequence.
