Lenses

What are the lenses made from? Coffee?
No, but our lenses are made from cellulose triacetate – recycled cotton, the world's most environmentally friendly lens material that exists today.

Which lenses do you use?
We use high-quality lenses in all our products. The basic sets include tinted UV-protective polarized lenses in brown or gray color for sunglasses and a clear set of lenses without any coatings for optical ones. Other than that, we offer a great variety of sun-protective and optical lenses, so you’ll be able to easily get the perfect ones for your prescription parameters or specific needs. Just click on the ‘select lenses’ option when making an order to choose your perfect frame+lenses combination. 

Are the lenses you use biodegradable?
Unfortunately, no. But they are made from cellulose triacetate, the most sustainable lens material that exists to this day.

Are the lenses you use recyclable?
Sadly, no. We couldn’t find any lens material that could be recycled. If you know about any, please let us know at hi@ochis.co — we would appreciate it a lot!

 

How do I take care of the lenses in Ochis?
Only clean the lenses with the cloth included in your parcel or other similar microfibre cloths. Don’t touch the lenses with fingers — hold the frames instead. Try not to scratch the lenses — even the tiniest pieces of dust can cause micro-scratches to them. Using the coffee-based hard case will save your Ochis from getting accidentally damaged inside your bag.

What types of lenses can you install?
After picking the model of eyewear, you can choose the lenses you need in the ‘Select Lenses’ section. Regular optical frames come with clear lenses and regular sunglasses — with tinted ones. 
We offer:  
- UV protection lenses (protecting your eyes from the sun’s harmful rays);
- Blue-light protection lenses (protecting your eyes from the light coming off screens);
- Photochromic lenses (changing their color from clear to tinted depending on the lighting around you and protecting your eyes from the sun’s harmful rays).
You can choose your perfect frame to lenses combination when making the order.

What are photochromic (adaptive and extra-adaptive) lenses?
Photochromic lenses are lenses that react to sun exposure. When you are inside, in darker places, they are clear so that you could see everything around you. If, on the other hand, you are outside or in a very bright place, the photochromic lenses will start to darken and turn your clear glasses into sunglasses. This mechanism helps your eyes to adjust to different lighting without pain and is especially helpful for people whose eyes are more receptive to light. Photochromic lenses also protect your eyes from UV-radiation.
The difference between adaptive lenses and extra-adaptive lenses is that the latter also have an anti-reflective coating and adjust to the surroundings quicker.

What are blue-light-protection (computer) lenses?
They are the lenses that help your eyes with looking at different screens without harm and strain. Computer and phone screens emit blue light, which is believed to be detrimental to the eyes, especially after extensive use. Our blue-light-blocking lenses have a special coating that will help your eyes to have a healthier workday.

What are high-index lenses?
High-index lenses are usually prescribed to people with high diopters parameters to compensate for the lens thickness. They are thinner and lighter than regular lenses with more extreme prescription parameters.

Is there any difference between gray and brown lenses?
Just the color, so choose whichever ones call out to you! Brown lenses will give a warmer tint to the world around you, and the gray ones provide for a colder one.

Which types of coating do your lenses have?

It depends on the type of lenses you choose to order. We have a variety of lenses we can install, each one with its own set of coatings.

Clear

Clear lenses without prescription parameters and without any coatings.

Tinted
Polarized lenses with sun-protective coating. Polarization helps to reduce glare from smooth surfaces like water when you’re outside. Be aware that they will most likely distort the images you see on screens. Tinted lenses come in gray or brown color.
Coating: UV + polarization

Tinted lenses with diopters / tinted lenses with diopters and astigmatic parameters
Vision correction lenses with sun protection. Tinted lenses come in gray or brown color.
Coating: UV + correction
Optional: astigmatism

Lenses with diopters / lenses with diopters and astigmatic parameters
Regular lenses that perform vision correction (according to your prescription parameters) and get scratched less. They have a number of coatings: they are anti-reflective and a 100% UV-protective. These lenses have a slight violet undertone.
Coating: anti-reflective + correction + UV protection 

Optional: astigmatism

High-index lenses with diopters / high-index lenses with diopters and astigmatic parameters
These high-index lenses are thinner than the regular ones and are usually used to compensate for the lens thickness in high diopters. They also have a multilayered strengthening anti-reflective and hydrophobic coating and get scratched less. These lenses have a slight green undertone.

Coating: anti-reflective + correction + high index + hydrophobic + astigmatism

Computer lenses / computer lenses with astigmatic parameters / high-index computer lenses / high-index computer lenses with astigmatic parameters
Lenses that make working on the computer harmless on the eyes, because the coating is specifically created to reflect the blue light coming from the screens. They are also anti-reflective and get scratched less. With or without prescription parameters. Could be high-index — thinner than the regular ones and usually used to compensate for the lens thickness in big diopters.
Coating: computer protection + anti-reflective 

Optional: correction + high index + astigmatism

Adaptive lenses / adaptive with astigmatic parameters
Lenses that go dark in the sun and become clear indoors, because they react to the amount of light in your surroundings. They are also anti-reflective and get scratched less. These lenses are sun-protective — they reflect the UV rays. Adaptive lenses come in gray or brown color.
Coating: UV + photochromic + anti-reflective
Optional: correction + astigmatism

High-index adaptive lenses
Lenses that go dark in the sun and become clear indoors, because they react to the amount of light in your surroundings. Strengthened water-, dirt- and dust-protective. With a slight turquoise undertone. Adaptive lenses come in gray or brown color.
Coating: UV + photochromic + correction + high index

Extra adaptive lenses / extra adaptive lenses with astigmatic parameters / high-index extra adaptive lenses / high-index extra adaptive lenses with astigmatic parameters
Lenses that quickly go dark in the sun, become clear indoors and get scratched less. You can work on your computer, walk in the sun or scroll through Instagram without harming your eyes. They are also anti-reflective and get scratched less. Extra adaptive lenses come in gray or brown color.
Coating: UV + photochromic + anti-reflective 
Optional: correction + high-index + astigmatism 

 

Prescription

Where can I get an eyewear prescription?
You can get your prescription at a local optician or eye practice. Find the nearest ophthalmologist or optometrist and go in for an eye exam.
*Please make sure that your specialist measures and writes down your interpupillary distance (PD/IPD). We require that parameter to install your chosen lenses correctly. 

Can you make Ochis according to my prescription?
Yes. We can install custom-made lenses with diopters and different prescription details including astigmatism. We also offer high-index lenses.
Please note that prescription lenses will take a bit longer to install, so you should remember to add an extra 2-5 days to the average waiting period.

How do I send you my prescription parameters?
To get our prescription glasses you just have to enter your prescription details in the appropriate boxes when you make the order on the website.

What do all the parameters in your prescription boxes mean?
OD - right eye, from Latin oculus dexter;
OS - left eye, from Latin oculus sinister;
*If your prescription contains OU - both eyes, from Latin oculus uterque, please enter the same parameters into both OD and OS boxes;
SPH (Sphere) - the amount of lens power for each eye specifically. The ‘+’ means you are farsighted, the ‘-’ means you are nearsighted. This parameter is measured in diopters, written D. 
*On our website you should enter your SPH into boxes named OD and OS respectively if you’ve checked the box that you don’t have astigmatism. If you do, the parameters boxes will specify the SPH as a separate parameter;
PD - pupillary distance, the distance between the pupil centers. 
CYL (Cylinder) - the amount of lens power for astigmatism, used to describe the part of the lens that should be cylindric rather than spherical to focus your sight properly;
Axis - the lens meridian that specifies exactly where astigmatism on your eye is and where your cornea doesn’t require a specific focusing.

Do you install lenses for astigmatism?
Yes, we do. After you choose your favorite frame design on our website, tick the prescription and astigmatism boxes and enter your parameters into the appropriate boxes.

Do I need high-index glasses?

If your optometrist or ophthalmologist suggests so or if you decide to install a thinner lens. High-index glasses are usually prescribed to people with high diopters (more than +/-2) to compensate for the lens thickness.

Can I get Ochis sunglasses with diopters?

Yes, you can. After you choose your favorite sunglasses design on our website, tick the prescription box and enter your parameters into the appropriate boxes.

Can I order more than 1 pair of Ochis with prescription parameters?
Yes, you can. Just enter your prescription parameters into the specific boxes when ordering another pair of Ochis.

Can my lenses be installed/replaced by my local optician?
If you wish to install them at your local optical store, you can easily do so, but we highly recommend that you let us do the job. Ochis aren’t your usual glasses, so there are some important rules to follow when installing new lenses. We know our material the best and will make sure that everything is done with the most attention to detail.
If you still choose to install them wherever else, make sure to always show these instructions to your optician to feel safe and sound. 
*These instructions are also included in the parcel.
To avoid frame damage, follow these steps:
1. Remove the lenses from the glasses by applying slight pressure.
2. When scanning the frame, attentively choose the measure of reducing the lens diameter depending on the type of lens you are installing. The bigger the lens diopter is, the more you should reduce it.
3. After the lenses have been cut out, slightly heat the frame (to a temperature of no more than 50°C/140°F). Don’t let the frames overheat — it may lead to cracks forming in the material.
4. Install the new lenses by gradually applying pressure across the lens perimeter. This should be done accurately, without extensive pressure against the frames.
