Contact Lens Prescription vs. Spectacle Prescription

Contact Lens Prescription vs. Spectacle Prescription 

This is an article forward from http://biofilcon.com/contact-lens-prescription/#more-800

Contact lens prescription does differ from spectacle prescription, mainly due to the distance between the spectacle and your eyes.

For those with spectacle prescription less than -4.00 D, the difference is insignificant. Patients can choose to wear either the same prescription or slightly lower. Spectacle prescription of -4.00D above, the difference with contact lens prescription will become more significant.

The chart below, is a conversion chart of spectacle prescription to contact lens prescription.

(-) Minus prescription is refer for short sighted or myopia. (+) Plus precription is refer for long sighted or hyperopia.

Besides that, a simple calculation can be done to determine your contact lens prescription (as the diagram below)

_________________from this part, it is my opinion _______________

What if the prescription you are looking for is not available?

1) Try to keep the left-right eye balance 

For example, I am shortsighted and have a left eye spectacle prescription of -6.00, which according to the chart, it is -5.62, my right eye is -5.25, according to the chart I need -5.00. 

I would like to keep my left - right eye difference ( which is now by a 0.75 difference) 

So I choose  -5.75 for my left, and -5.00 for my right. 

2) Try to choose the power closest to your prescribed power. 

So some contact brands does not have -5.75 prescriptions. They only have -5.50 or -6.00. 

So I decide to go with -5.50 instead of -6.00, because my real prescription according to chart is -5.62 (closer to -5.50 an further to -6.00)

3) Go with your feeling. 

Sometimes you just need to try to know which one is better. Just try and feel it out. Order both prescriptions and try them out for a day. 

Hope this helps and Good Luck! 

i.Fairy Ruby Red Circle Lens Review

Hello! I bought the lens for Halloween and quite surprised about how comfy and bright they are. These lens are really red. These ones have a black ring outside. Got them for $21.95 from Candylens
Some basics:

Diameter:

14.5mm

42%

8.6mm

Design: ★★★★☆ 

The design of these lens are nice bright red colour, with a black ring on the outside. I love the intensity of these lens, they are definately not natural colour. (Well, if you are thinking about getting a pair of red lens, the chances are that you don't want natural colour!)

Comfort  ★★★★★
Extremely comfortable! Wear these for 6+ hours and still felt alright. 

Enlargement★★★★☆ 
These are 14.5 mm, the enlargement was big enough for me, but my eyes are on the small side.

Casual Shinny Black Nail Colour for Halloween

The Halloween is coming in two days, I am just as excited as a little kid. I used to feel Halloween is boring and was never a party person, but this year, something in the air make me feel spooky and fun.

Casual Black Nail Colour for Halloween

What did I use? 

COVERGIRL outlast glosstinis color: black heat (Base coat) 

Coverage: ★★☆☆☆
I needed to apply 2-3 coats to get nails covered. So really low coverage, the instruction also tells you to apply 2-3 coats. So I am not too surprised.


Application: ★☆☆☆☆

Really hard to apply not smooth and it was a little chunky, feels like an old nail polish passed expiration date.


Color /design: ★★★★☆
Color is not bad, the black heat color ended up a deep black with small golden sparkles. Although it is more black than shine. So that's why I topped it with a sparkle coat.


Hardness: ★★☆☆☆
It was kind of a soft coat, I was afraid that it was going to be easily peeled off.

from Pinterest (What Gem Crush big money looks like) 

This review is for Gem crush big money to be used alone. 

Application: ★★★★☆ 
Really easy to apply. Quite smooth (Not as smooth as OPI, of course).

Color /design: ★★★★☆ 
Love the color, one of my favourite from last year. It is a beautiful colour for winter holiday.

Hardness: ★★★★★
It gives a very hard coat. One thing to know is that it is very hard to come off. It took me so much time to clear it out.

As a top coat, it is excellent, because it gave me a really hard coat that prevent chipping. I love the sparkles. I only did one coat of it. 

Coverage: ★★★☆☆ 

I needed to apply 2-3 coats to get the effects in the picture, but that's what all sparkles, shinning nail polishes are like. So no complaints.

I finally got some time to take pictures of my new circle lens from Candylens.

There is a review of Vassen Rainbow Eyes Grayish Blue. I always wanted a pair of light grey lens. The colour looked great. I was worried that it may look weird close up because they looked so fake. However, from distance, the contacts looked wonderful, and I am really happy with the purchase.

Some basic information about the lens:
Brand:Vassen
Disposal: Yearly
Water Content: 38%
Diameter: 14.5 mm
Base Curve: 8.6

Ratings~

Design: ★★★✩✩ 3.5/5  There are a little unnatural looking when you look very close. But from distance, they are very legit gray contacts and opaque. I like the design, but do not love them. The black rings are quite visible, but not in a bad way. 

Comfort ★★★★★ 5/5 Very good! You can't feel them at all. I am very surprised by how comfortable these are (I have heard mostly good reviews on comfortableness about Vassen brand, glad they are correct!). I have really sensitive and dry eyes, so these are great. Haven't tried to wear them for a long period yet. So cannot give my word on how long these will last yet.  

Enlargement ★★★★★ 5/5 These are 14.5 mm, give you decent enlargement without making your eyes look freaky. I have relatively small eyes, so these are great size for me. My clear contacts are 13.8 mm and my usual circle lens are 14.2 mm. 

Vision   ★★★★★ 5/5 Clear vision, no problem with seeing at all. It does not move when I look away, they stay in perfect position. No blurs. 

Overall  ★★★★✩ 4/5 I give these 4 stars because of the comfort level and its enlargement. It lost one star because they do look kind of fake when you look at them close up.  

G&G Dueba Puffy 3 Tone Turquoise Review

G&G Puffy 3 Tone Turquoise

I was very excited to try out the puffy 3 tone turquoise. I am a big fan of the turquoise and aqua colours. The puffy 3 tone is a great series with comfortable wears. I ordered these from Candylens 

The bottle cap says "sky", which confused me a lot.

Design: ★★★✩✩ 3.5/5 Colour is not as bright as I thought, somehow I imagined these to be much more vibrant. 

Comfort ★★★★★ 5/5 AMAZING! Same as the Puffy Brown. I can't even feel them in my eyes. 

Enlargement ★★★★★ 5/5 These are 14.5 mm, give you great enlargement without making your eyes look freaky. I have relatively small eyes, so these are great size for me. My clear contacts are 13.8 mm and my usual circle lens are 14.2 mm. 

Vision   ★★★★★ 5/5 Clear vision, no problem with seeing at all. It does not move when I look away, they stay in perfect position. No blurs. 

Overall  ★★★★✩ 4/5 I give these 4 stars because of the comfort level, naturalness of the design, and its clear vision. Minus one star because of they are not as vibrant as I thought. But this would be a great pair for an enlarging natural look. It is opaque enough to let people see that you have a different eye colour.  

Dueba Shinny Brown (known as Puffy 3 tone) Review

My order from Candylens comes in, I have ordered the lens with their free Fedex shipping over $100 plus buy two get one pair free promotion.

Dueba Puffy 3 Tone has always been a series I wanted to try. I loved how it lighten up the eyes on all other people's pictures. However there were a couple things that I worried. One is the base curve ( these are 8.8 base curve), my eyes are 8.5. So I was worried that they won't be as comfortable or have a weird bubble. Second is the size of 14.5 mm. My normal lens are 14.00 mm or 14.2 mm. So I was worried they are going to look kind of fake.

In the end, I found that I didn't need to worry about these ones. Dueba Shinny Brow (Puffy 3 Tone) were super comfortable and my eyes did not look freaky.

So here are some pictures:

Ratings~

Design: ★★★★★ 5/5 Love the pattern, it is very natural looking. There is a black ring, but not dominant (which I like because I prefer contacts without black rings)  They enlarge my eyes and lighten them up, make my eyes look like a natural medium/ light brown. The exact effect I am looking for. 

Comfort ★★★★★ 5/5 AMAZING! You can't even feel it. I have to say that I am very surprised by how comfortable these are. I have really sensitive and dry eyes, so these are perfect. Haven't tried to wear them for a long period yet. So cannot give my word on how long these will last yet.  

Enlargement ★★★★★ 5/5 These are 14.5 mm, give you great enlargement without making your eyes look freaky. I have relatively small eyes, so these are great size for me. My clear contacts are 13.8 mm and my usual circle lens are 14.2 mm. 

Vision   ★★★★★ 5/5 Clear vision, no problem with seeing at all. It does not move when I look away, they stay in perfect position. No blurs. 

Overall  ★★★★★ 5/5 I give these 5 stars because of the comfort level and naturalness of the design, and its clear vision. 

Think these ones are going to be my favorite lens. 

How to Open Circle Lens Vials- Step by Step Pictures

Hello, when I first ordered circle lens, I wasn't really sure how to open the vials so that they don't break. If a vial breaks during the process, it is usually extremely hard to get it to open.

So here is a step by step post about opening the circle lens vials.

Step 1: Look for the mark for opening direction. 
There is usually an arrow signifying where to open. Find the arrow.

Step 2: Open the vial cap by lifting it up away from the arrow mark. 

Make sure to stop mid-way. Do not do it too fast. 

Step 3: Slowly rotate to left or right to open the second section of the vial

Once you successfully opened the vial to this stage, you are good to go. The rest will come off easily. 

Step 4:Take off the vial and take off the rubber stopper

        

Step 5: Pour the solution and the lens onto your hands in a quick motion. 

Get rid of the water, pick up the lens and put them away into lens cases. 

Step 6: Store the lens into the lens cases (make sure don't mix up left and right if you have prescription) with soft contact lens solutions.

Some vials are harder to open than others. Hope this helps! Good Luck!
