What does it mean when you feel that the way you see feels uncomfortable?

This generally means that your brain sees portions of your new lenses that work differently from those of your old eyeglasses as strange.
There is the type of discomfort that you do not need to worry about where you get accustomed to them after a while, and there is the type of discomfort where immediate inspections at the shop where you purchased them or by your ophthalmologist are required.
You can also use your lenses comfortably by knowing their characteristics.

Please see our advice on the forms of discomfort classified by symptom, cause, and how to cope with your situation.

Symptom 1
I had my latest lenses mirror-coated.
Although they are no-color lenses, vision seemed whitened and not clear when I tried them on.

Cause

There is reflection of colors from the back surfaces because the mirror effects are also exerted there

Explanation

Mirror coating is applied on the front surfaces of lenses but the mirror reflection changes in accordance with the conditions of the base.
The mirror effects can also be exerted in the back surfaces of the lenses.

This means that mirror reflection will be the most intense if, for example, mirror coating is applied on a substance with zero permeability.

We are also sometimes told by customers that they suddenly discover webby lines all over their spectacle lenses. This is thought to be caused by heat.
However, the mirror reflection will be weaker on the front surfaces and more powerful on the back surfaces if mirror coating is applied on lenses with lighter colors or on no-color lenses such as in this case.
This effect causes whitened vision.

Mirror reflection varies not only according to lens colors, but to the environments where they are used as well.
For example, the lenses will be in the same condition as those that are darkly colored when worn in the early evening or later hours so the mirror reflection appears more powerful.

The photos below are of the same eyeglasses where a gold mirror coating has been applied on no-color lenses. The mirror reflection is more powerful when they are placed on a black object while there is almost no reflection when they are placed on a white object.

The photos below are of the angles of the inner sides of the eyeglasses in the photos above being altered.
The reflection is not as powerful when the eyeglasses are actually worn by the user as they are covered by the user’s face, but there may still be concern over some reflection.

There is the issue of what kinds of colors should be added to the lenses or how the differences in environments can alter the mirror reflection or produce mirror effects on the back surfaces. However, we would like to add that there are many users who are aware of these points and that they are satisfied with the differences in the mirror reflection because they serve as fashionable eyeglasses.

Symptom 2
I made them with a frame that looks like one for sunglasses.
I cannot use them because they make round objects look elliptic and straight lines look curved.

Probable cause

Objects look distorted because of the heavily curved design of the frame

Explanation

Distortions may occur if astigmatic power is high, but the point here is the frame that looks like one for sunglasses.
Frames with curves that fit the shape of the face more than regular frames may cause discomfort even if lenses of the same power are used.

If your new eyeglasses are more curved when looking at the eyeglass frames from above, the lens surfaces are facing outwards even though normal ones face directly forward as shown in the photos below.

You are looking at an object from an angle when looking directly ahead. Myopic power is stronger at the part of the lenses toward your nose while it is weaker at the part towards your ears. This is why objects directly in front of you appear condensed or why it can appear blurry when glancing sideways.
Although you will have to change the design of your frame, this can be solved by having the angles adjusted at your eyeglass shop in this case. However, there is a limit to how much they can be adjusted as overdoing it can break your frame.

If you have selected an eyeglass frame with a very curvy design, you can continue using it comfortably while maintaining its design if it has been made to fit not only with the curves of the lenses but with the camber angle as well.

However, there is a limit to how far this can be taken with such lenses so a frame that is a little less curvy should be selected when using lenses that are particularly high in power.

The possibility of such symptoms arising increases as power is enhanced or as the designs of frames get curvier. Those with less power are also lenses that fit curves rather than being specialized lenses and there are many users who see them as comfortable to use (perhaps they are easy to get accustomed to right away). Those who want curvy frames should visit their eyeglass shops for consultation.

Symptom 3
I cannot see very well with my new eyeglasses.

Probable cause

It is difficult to determine the cause as there can be many

Measures by condition

(1) I cannot see what is right in front of me with types where the powers change such as those for both short and far distances, those for short and intermediate distances, and those for short distances.

Step 1. Please shift your vision downward and look at an object such as a newspaper through the bottom part of your lenses without moving your face and while being aware that lenses are designed to change in power when viewing from the top parts to the bottom parts.

Step 2. Shift your vision up and down and move the newspaper closer and farther to find the position where it is the easiest to see. There is always a position where it is easy to see.

If you cannot see it without moving it extremely far away or if the position must be different from what it normally is, please explain this to the shop where you purchased them.
There are some that can be improved by adjusting the lenses, but they may be determined as requiring adjustments in power if adjustments of the lenses do not show good results.
However, the power that you decided on was based on factors such as how well you saw with them.

(2) Far places look blurry when using types for both short and far distances

Step 1. Turn your face directly ahead, pull your jaw back slightly, and glance slightly upward.

Step 2. Find a spot that you can see clearly while changing the far distance that you are looking at.

Step 3. Please visit the shop where you purchased them if you wish that you could see more.
However, there is the possibility that your lenses can make you tired if they are of a power that lets you see too much, so please remember that they might have been made with slightly less power.

(3) It is difficult to see with one lens of this power (single-vision lens)

Find a spot with a good focal point while changing distances and keeping in mind that the focal lengths of the lenses changes according to power.
Please consult with your eyeglass shop if the distance where you can see clearly is not what you had expected.

(4) Objects look distorted with single-vision lenses

This is a phenomenon that often occurs when curved or large frames are selected as in Symptom 2, or power (including astigmatic power) is increased.
The change in power may be the cause if the shape of the frame is not so different from that of your previous frame.
There is no need to worry if you get accustomed to them after a while, but please consult with the shop where you purchased them if they make you feel extremely ill or you do not get accustomed to them even after a long time as they may need adjustments in power.
